  1. A Framework for Assessing and Managing Large Purchaser - Minority Supplier Relationships in Supplier Diversity Initiatives

    OpenAIRE

    Theodorakopoulos, Nicholas; Ram, Monder

    2008-01-01

    Supplier diversity initiatives can function as platforms for EMSs strategic learning (Theodorakopoulos et al., 2005; Theodorakopoulos & Ram, 2006) and the scant research in supplier diversity underscores the importance of relationship factors to the success of supplier diversity/development programmes (e.g. Pearson et al., 1993). However, purchaser-supplier relationship management as a vehicle for enhancing EMSs learning and supply capabilities has not been examined to any length within the c...

    Sommer, Anita Friis; Dukovska-Popovska, Iskra; Steger-Jensen, Kenn

    2013-01-01

    Increased market demand and shortened product life cycles generate industrial customer requests for collaborative product development. Manufacture-to-stock suppliers struggle to manage the request process to obtain profitability. The purpose of this paper is to investigate if request management...... is profitable for suppliers, and to examine possible relations between profitability of requests and the requesting customer. Through a case study, request management is identified as a profitable process due to long-term accumulated profit from developed products. Request profitability is not identified...... as related to profitability or turnover of existing customers, and thus profitability of requests cannot be predicted based on these customer data. Results from a coupled interview study indicate that request management has a large potential for future exploitation, and an outline of the supplier value...

    The prevailing research in supplier innovation has been conceptual or based on small data sets. The analysis of a large data set gives a clearer perspective on the actual type and degree of involvement of suppliers in the customer’s innovation process. The supplier perspective of the research...... counterbalances the customer bias that exists in the prevailing literature in this area. Similarly, the issue of the benefit of supplier involvement in the innovation/NPD process can be better understood. Manufacturing suppliers benefit financially from their involvement in the innovation/NPD process of their key...

  8. Affecting the value chain through supplier kaizen.

    Science.gov (United States)

    Forman, C R; Vargas, D H

    1999-02-01

    In the aerospace industry, typically 60 percent of a product's cost and 70 percent of the lead time are due to purchased material. To affect price and customer responsiveness, improvement initiatives must be extended into the supply chain. Many companies have developed supply base management systems that include long-term agreements with suppliers, partnering with suppliers in risk taking and product design, information sharing, and quality and delivery rating systems. The premise is that suppliers are an extension of the factory. But to take full advantage of customer-supplier relationships, the suppliers must be "developed" in the same manner as a manufacturing unit. Supplier kaizen is a method of bringing suppliers to the same level of operations as the parent company, through training and improvement projects, to ensure superior performance and nurture the trust that is required for strong partnerships. This article describes Sikorsky Aircraft's use of kaizen to improve its supply base management.

  10. Emerging nuclear suppliers

    International Nuclear Information System (INIS)

    Sands, A.

    1990-01-01

    Efforts to prevent the spread of nuclear weapons have usually taken two tracks: The traditional approach has concentrated on a potential proliferant's perceived need for nuclear technology and possibly weapons; a second approach has targeted the supply side of the proliferation equation. The issue being examined in this book---emerging nuclear suppliers---falls between these two approaches. The potential proliferants have emerged as possible unrestrained suppliers of nuclear materials and technology. They threaten the entire nonproliferation regime by their exporting, not their weapons development. Analyzing and understanding the issue of emerging suppliers requires a refined definition of suppliers in general. The simple dichotomy of traditional versus emerging suppliers is no longer an adequate framework for analysis. Suppliers differ significantly in their technical capabilities, experience, and regime involvement, and these distinctions result in different nuclear export policies

  11. Dependence on Supplier, Supplier Trust and Green Supplier Integration: The Moderating Role of Contract Management Difficulty

    Directory of Open Access Journals (Sweden)

    Xuesong Zhao

    2018-05-01

    Full Text Available This study aims to investigate the impacts of dependence on supplier and supplier trust on green supplier integration, and the moderating role of contract management difficulty. In this study, we develop a dependence-trust-integration model based on resource dependence theory, social capital theory and transaction cost theory. We examine the hypothesized relationships using hierarchical regression analyses based on data collected from 187 Chinese firms. Our findings suggest that dependence on supplier has positive impacts on green supplier integration and supplier trust. Supplier trust partially mediates the relationship between dependence on supplier and green supplier integration. In addition, contract management difficulty negatively moderates the relationship between supplier trust and green supplier integration. This research contributes to the literature by offering empirical evidence concerning the indirect relationship between dependence on supplier and green supplier integration via supplier trust, and the trust-integration link depends on the level of contract management difficulty.

    Since the early 1980s, a growing amount of attention has been paid to a small group of mostly developing countries that have come to be called the emerging nuclear suppliers. Argentina and Brazil, China and South Korea, India and Pakistan, Spain and Yugoslavia have frequently been mentioned in this category. Their actual and potential nuclear export dealings and policies have been the subject of academic writings and policy papers, of scholarly symposia and exchanges at meetings of the traditional nuclear suppliers. With foundation and other support, UCLA's Center for International and Strategic Affairs has begun a major project to develop a database on the transactions, policies, and export control institutions of the emerging suppliers. This chapter provides some guidelines for policy toward the emerging nuclear suppliers

    1990-01-01

    This paper reports that with the appearance of such third-tier suppliers as Argentina, Brazil, South Korea, Taiwan, China, and others capable of producing nuclear components and sensitive nuclear materials, assurance that importers are using nuclear energy benignly and safely may become more uncertain. It is therefore important to integrate emerging exporters and importers into a regime of norms designed to minimize nuclear risks. The experience of the London Nuclear Suppliers Group (NSG) to arrive at a code of conduct is encouraging. Placed in the context of the larger evolving nuclear energy regime that seeks to address nuclear safety, proliferation, terrorism, and military attacks on reactors, the international community has made substantial progress. Still, there is much that remains to be done

    This is document is a guide for conducting quality assurance inspections of transportations packaging suppliers, where suppliers are defined as designers, fabricators, distributors, users, or owners of transportation packaging. This document can be used during an inspection to determine regulatory compliance within the requirements of 10 Code of Federal Regulations, Part 71, Subpart H (10 CFR 71.101--71.135). The guidance described in this document provides a framework for an inspection. It provides the inspector with the flexibility to adapt the methods and concepts presented here to meet the needs of the particular facility being inspected. The guide was developed to ensure a structured and consistent approach for inspections. The method treats each activity at a supplier facility as a separate entity (or functional element), and combines the activities within the framework of an ''inspection tree.'' The method separates each functional element into several areas of performance and then identifies guidelines, based on regulatory requirements, to be used to qualitatively rate each area. This document was developed to serve as a field manual to facilitate the work of inspectors. 1 ref., 1 fig., 5 tabs

    2014-01-01

    Supplier selection plays an important role in the supply chain management and traditional criteria such as price, quality, and flexibility are considered for supplier performance evaluation in researches. In recent years sustainability has received more attention in the supply chain management literature with triple bottom line (TBL) describing the sustainability in supply chain management with social, environmental, and economic initiatives. This paper explores sustainability in supply chain management and examines the problem of identifying a new model for supplier selection based on extended model of TBL approach in supply chain by presenting fuzzy multicriteria method. Linguistic values of experts' subjective preferences are expressed with fuzzy numbers and Neofuzzy TOPSIS is proposed for finding the best solution of supplier selection problem. Numerical results show that the proposed model is efficient for integrating sustainability in supplier selection problem. The importance of using complimentary aspects of sustainability and Neofuzzy TOPSIS concept in sustainable supplier selection process is shown with sensitivity analysis.

    2013-01-01

    In today's global marketplace, businesses are becoming increasingly reliant on suppliers for the provision of key processes, activities, products and services in support of their strategic business goals. The result is that now, more than ever, the failure of a key supplier has potential to damage reputation, productivity, compliance and financial performance seriously. Yet despite this, there is no recognised standard or guidance for identifying a tier one key supplier base and, up to now, there has been little or no research on how to do so effectively. This paper outlines the key findings of a BCI-sponsored research project to investigate good practice in identifying tier one key suppliers, and suggests a scalable framework process model and risk matrix tool to help businesses effectively identify their tier one key supplier base.

    1989-01-01

    Experimental and numerical studies were performed to investigate crack initiation behavior near a surface of stainless steel and tungsten when subjected to extremely high heat flux. The improved electron beam test facility was used as the heat source. Two-dimensional thermal and elasto-plastic stress analyses were also performed. From the results for stainless steel, micro-cracks about 0.1 mm deep only initiated in the resolidified layer along dendrites. No cracks propagated into the non-melted zone, and repeated heating of up to 20 times did not affect the depth and population of the cracks. According to the elasto-plastic stress analyses, no fatigue cracks were expected. Cracks with a depth of more than a few millimeters were observed in a tungsten plate. The cracks initiated at a boundary between heated and unheated areas. They grew into the non-melted zone, and curved towards the center part of the heated area. The elasto-plastic stress analyses indicated that the cracks were initiated due to the residual tensile strain after heated at the surface of the test specimen. When the heat flux was repeated, the cracks propagated and penetrated to the rear side of the test specimen in several repetition. (author)

    1983-01-01

    The pH step alkaline elution and alkaline sucrose gradient techniques were utilized to evaluate alterations in DNA replication (initiation and elongation) induced by heat and low dose X-irradiation in synchronized Chinese hamster ovary cells. The initiation and elongation processes of DNA synthesis were radioresistant at the G 1 /S boundary (4 hours after mitosis) while in mid S phase (9 hours after mitosis) DNA initiation and elongation were sensitive to X-irradiation. The initiation and elongation processes of DNA synthesis which were radiation resistant at the G 1 /S boundary could be inhibited by a hyperthermia treatment (43 0 C for 1 hour beginning at 4 hours after mitosis). The impairment of initiation in the heated cells was maintained through late S phase while that of elongation was reversible as judged by full recovery at 15 hours after mitosis. These data suggest that the known synergistic lethality of heat and radiation may be mediated by an impairment of initiation of DNA synthesis. (author)

  7. Understanding Supplier Resistance - Overcoming Obstacles to Supply Innovation

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available This paper explores an important but unexplored theme in the development of 'total quality' relationships in the supply chain: why suppliers may exhibit resistance to quality initiatives, and why what seems to customers as cooperation can appear as unwelcome interference or even exploitation to suppliers. This is a question of great relevance to all those seeking to understand current business practice, and also to those seeking to bring about practical improvements in supply chain quality. Too much of the supply chain and quality literature assumes the issue of supplier's compliance with customer initiatives is unproblematic (unable to understand this sentence; experience suggests it is one of the major obstacles in developing the quality-oriented, integrated supply chain.

    The total loss of the ultimate heat sink is an initiating event which, even it is mainly of external origin, has been considered in the frame of internal events Level 1 PSA by IRSN. The on-going actions on the development of external hazards PSA and the recent incident of loss of the heat sink induced by the ingress of vegetable matter that occurred in France in 2009 have pointed out the need to improve the modeling of the loss of the heat sink initiating event and sequences to better take into account the fact that this loss may be induced by external hazards and thus affect all the site units. The paper presents the historical steps of the modeling of the total loss of the heat sink, the safety stakes of this modeling, the main assumptions used by IRSN in the associated PSA for the 900 MWe reactors and the results obtained. The total loss of the heat sink was not initially addressed in the safety demonstration of French NPPs. On the basis of the insights of the first probabilistic assessments performed in the 80's, the risks associated to this 'multiple failure situation' turned out to be very significant and design and organisational improvements were implemented on the plants. Reviews of the characterization of external hazards and of their consequences on the installations and French operating feedback have revealed that extreme hazards may induce a total loss of the heat sink. Moreover, the accident that occurred at Fukushima in 2011 has pointed out the risk of such a loss of long duration at all site units in case of extreme hazards. In this context, it seems relevant to further improve the modelling of the total loss of the heat sink by considering the external hazards that may cause this loss. In a first step, IRSN has improved the assumptions and data used in the loss of the heat sink PSA model, in particular by considering that such a loss may affect all the site units. The next challenge will be the deeper analysis of the impact of external hazards on

    Cryogen spray cooling (CSC) is used to minimize the risk of epidermal damage during laser dermatologic therapy. However, the dominant mechanisms of heat transfer during the transient cooling process are incompletely understood. The objective of this study is to elucidate the physics of CSC by measuring the effect of initial substrate temperature (T 0 ) on cooling dynamics. Cryogen was delivered by a straight-tube nozzle onto a skin phantom. A fast-response thermocouple was used to record the phantom temperature changes before, during and after the cryogen spray. Surface heat fluxes (q'') and heat-transfer coefficients (h) were computed using an inverse heat conduction algorithm. The maximum surface heat flux (q'' max ) was observed to increase with T 0 . The surface temperature corresponding to q'' max also increased with T 0 but the latter has no significant effect on h. It is concluded that heat transfer between the cryogen spray and skin phantom remains in the nucleate boiling region even if T 0 is 80 0 C

    1984-03-01

    Gap heat transfer between fuel pellet and cladding have a large influence on the LWR fuel behaviors under reactivity initiated accident (RIA) conditions. The objective of the present study is to investigate the effects of gap heat transfer on RIA fuel behaviors based on the results of the gap-gas parameter tests in NSRR and on their analysis with NSR-77 code. Through this study, transient variations of gap heat transfer, the effects of the gap heat transfer on fuel thermal behaviors and on fuel failure, effects of pellet-cladding sticking by eutectic formation, and the effects of cladding collapse under high external pressure have been clearified. The studies have also been performed on the applicability and its limit of modified Ross and Stoute equation which is extensively utilized to evaluate the gap heat transfer coefficient in the present fuel behavior codes. The method to evaluate the gap conductance to the conditions beyond the applicability limit of the Ross and Stoute equation has also been proposed. (author)

  20. An integrated model for supplier selection process

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    In today's highly competitive manufacturing environment, the supplier selection process becomes one of crucial activities in supply chain management. In order to select the best supplier(s) it is not only necessary to continuously tracking and benchmarking performance of suppliers but also to make a tradeoff between tangible and intangible factors some of which may conflict. In this paper an integration of case-based reasoning (CBR), analytical network process (ANP) and linear programming (LP) is proposed to solve the supplier selection problem.

    2014-01-01

    Full Text Available Suppliers are one of the most vital parts of supply chain whose operation has significant indirect effect on customer satisfaction. Since customer's expectations from organization are different, organizations should consider different standards, respectively. There are many researches in this field using different standards and methods in recent years. The purpose of this study is to propose an approach for choosing a supplier in a food manufacturing company considering cost, quality, service, type of relationship and structure standards of the supplier organization. To evaluate supplier according to the above standards, the fuzzy inference system has been used. Input data of this system includes supplier's score in any standard that is achieved by AHP approach and the output is final score of each supplier. Finally, a supplier has been selected that although is not the best in price and quality, has achieved good score in all of the standards.

  4. Method for solving the problem of nonlinear heating a cylindrical body with unknown initial temperature

    Science.gov (United States)

    Yaparova, N.

    2017-10-01

    We consider the problem of heating a cylindrical body with an internal thermal source when the main characteristics of the material such as specific heat, thermal conductivity and material density depend on the temperature at each point of the body. We can control the surface temperature and the heat flow from the surface inside the cylinder, but it is impossible to measure the temperature on axis and the initial temperature in the entire body. This problem is associated with the temperature measurement challenge and appears in non-destructive testing, in thermal monitoring of heat treatment and technical diagnostics of operating equipment. The mathematical model of heating is represented as nonlinear parabolic PDE with the unknown initial condition. In this problem, both the Dirichlet and Neumann boundary conditions are given and it is required to calculate the temperature values at the internal points of the body. To solve this problem, we propose the numerical method based on using of finite-difference equations and a regularization technique. The computational scheme involves solving the problem at each spatial step. As a result, we obtain the temperature function at each internal point of the cylinder beginning from the surface down to the axis. The application of the regularization technique ensures the stability of the scheme and allows us to significantly simplify the computational procedure. We investigate the stability of the computational scheme and prove the dependence of the stability on the discretization steps and error level of the measurement results. To obtain the experimental temperature error estimates, computational experiments were carried out. The computational results are consistent with the theoretical error estimates and confirm the efficiency and reliability of the proposed computational scheme.

    Accurate label-free methods or assays to obtain the initial reaction rates have significant importance in fundamental studies of enzymes and in application-oriented high throughput screening of enzyme activity. Here we introduce a label-free approach for obtaining initial rates of enzyme activity from heat measurements, which we name initial rate calorimetry (IrCal). This approach is based on our new finding that the data recorded by isothermal titration calorimetry for the early stages of a reaction, which have been widely ignored, are correlated to the initial rates. Application of the IrCal approach to various enzymes led to accurate enzyme kinetics parameters as compared to spectroscopic methods and enabled enzyme kinetic studies with natural substrate, e.g. proteases with protein substrates. Because heat is a label-free property of almost all reactions, the IrCal approach holds promise in fundamental studies of various enzymes and in use of calorimetry for high throughput screening of enzyme activity.

    Non-lethal hyperthermia is used clinically as adjuvant treatment to radiation, with mixed results. Denaturation of protein during hyperthermia treatment is expected to synergize with radiation damage to cause cell cycle arrest and apoptosis. Alternatively, hyperthermia is known to cause tissue level changes in blood flow, increasing the oxygenation and radiosensitivity of often hypoxic tumors. In this study, we elucidate a third possibility, that hyperthermia alters cellular adhesion and mechanotransduction, with particular impact on the cancer stem cell population. We demonstrate that cell heating results in a robust but temporary loss of cancer cell aggressiveness and metastatic potential in mouse models. In vitro, this heating results in a temporary loss in cell mobility, adhesion, and proliferation. Our hypothesis is that the loss of cellular adhesion results in suppression of cancer stem cells and loss of tumor virulence and metastatic potential. Our study suggests that the metastatic potential of cancer is particularly reduced by the effects of heat on cellular adhesion and mechanotransduction. If true, this could help explain both the successes and failures of clinical hyperthermia, and suggest ways to target treatments to those who would most benefit. - Highlights: • Non-lethal hyperthermia treatment of cancer cells is shown to cause a reduction in rates of tumor initiation and metastasis. • Dynamic imaging of cells during heat treatment shows temporary changes in cell shape, cell migration, and cell proliferation. • Loss of adhesion may lead to the observed effect, which may disproportionately impact the tumor initiating cell fraction. • Loss or suppression of the tumor initiating cell fraction results in the observed loss of metastatic potential in vivo. • This result may lead to new approaches to synergizing hyperthermia with surgery, radiation, and chemotherapy

  8. On choosing a nonlinear initial iterate for solving the 2-D 3-T heat conduction equations

    2009-01-01

    The 2-D 3-T heat conduction equations can be used to approximately describe the energy broadcast in materials and the energy swapping between electron and photon or ion. To solve the equations, a fully implicit finite volume scheme is often used as the discretization method. Because the energy diffusion and swapping coefficients have a strongly nonlinear dependence on the temperature, and some physical parameters are discontinuous across the interfaces between the materials, it is a challenge to solve the discretized nonlinear algebraic equations. Particularly, as time advances, the temperature varies so greatly in the front of energy that it is difficult to choose an effective initial iterate when the nonlinear algebraic equations are solved by an iterative method. In this paper, a method of choosing a nonlinear initial iterate is proposed for iterative solving this kind of nonlinear algebraic equations. Numerical results show the proposed initial iterate can improve the computational efficiency, and also the convergence behavior of the nonlinear iteration.

    An experiment to understand the complexity of boiling phenomena on a narrow gap, which has occurs in severe accident at TMI-2 NPP is necessary to be done in aimed to increase the understanding of accident management. The goal of research is to obtain a heat flux and critical heat flux (CHF) value during boiling heat transfer process in a narrow gap annulus. The method of research is experimental using HeaTiNG-01 test section. The experiment has been done with heating-up heated rod until a certain initial temperature, for this experiment, three initial temperature variations was decided at 650°C, 750°C dan 850°C. Then, a cooling process in heated rod by saturated water was recorded based on temperature data changes. Temperature data was used to calculate a value of heat flux and wall superheat temperature, until the results could be defined in boiling curve. The result of this research shows that, although the initial temperature of heated rod was different, the value of CHF is almost similar with CHF average 253.7 kW/m 2 with the changes of only 4.7%. The event of boiling in a narrow gap is not included pool boiling category based on the comparison of film boiling area of the experiment to Bromley correlations. (author)

    Local heat transfer has been experimentally studied on the initial portion of the flat channel in the turbulent air flow. The channel measures 37.5 mm in height and 212.5 mm in width. The heat transfer measurements have been taken at inlet flow turbulence of epsilon 0 =0.7-0.8%. The charts are plotted showing variation of trannser with inlet and additional agitation of the flow. Critical values are found of the Reynolds number which are characteristic of the zones with various types of flow (laminar, transient and turbulent) at epsilon 0 =0.7-0.8%: Resub(crit 1) = 9.3x10sup(4), Resub(crit 2) = 2.9x10sup(5). With the increase of epsilon 0 up to 5% and above, the flow in the boundary layer becomes turbulent practically from the very beginning of the experimental portion. Considerable increase has been revealed of the heat transfer in this group of the experiments. At epsilon (>=) 5% the heat transfer grows up regularly

    High current discharge channels can neutralize both current and space charge of very intense ion beams. Therefore, they are considered an interesting solution for final focus and beam transport in a heavy ion beam fusion reactor. At the Gesellschaft für Schwerionenforschung accelerator facility, 50 cm long, free-standing discharge channels were created in a 60 cm diameter metallic chamber. Discharges with currents of 45 kA in 2 to 25 mbar ammonia (NH3) gas are initiated by a CO2 laser pulse along the channel axis before the capacitor bank is triggered. Resonant absorption of the laser, tuned to the v2 vibration of the ammonia molecule, causes strong gas heating. Subsequent expansion and rarefaction of the gas prepare the conditions for a stable discharge to fulfill the requirements for ion beam transport. The influence of an electric prepulse on the high current discharge was investigated. This article describes the laser-gas interaction and the discharge initiation mechanism. We found that channels are magnetohydrodynamic stable up to currents of 45 kA, measured by fast shutter and streak imaging techniques. The rarefaction of the laser heated gas is studied by means of a one-dimensional Lagrangian fluid code (CYCLOPS) and is identified as the dominant initiation mechanism of the discharge.

  12. Studying the emerging nuclear suppliers

    1990-01-01

    None of these events---nor any of the many others that are cited in the case studies of this book---can be singled out as heralding a revolutionary transformation of the global nuclear marketplace. The cumulative effect of such developments, however, may well be the emergence of a market in the year 2000 that is far less concentrated than today's market for nuclear reactors and fuel cycle technology. If this gradual structural transformation is accompanied by the entry into the market of new buyers and sellers that do not accept the Nuclear Non-Proliferation Treaty (NPT), safeguards administered by the IAEA, or other international norms directed at preventing the spread of nuclear weapon capabilities, the result may indeed have revolutionary dimensions for the business, diplomacy, and research of nuclear energy. A similar outcome could arise even f these norms are widely accepted but are not matched by an increase in the resources available to national governments and key international agencies that implement these norms. This paper identifies some of the pitfalls that researchers often encounter in researching the emerging suppliers and will outline some basic ground rules to guide the collection and interpretation of empirical evidence on supplier behavior

    2015-01-01

    Full Text Available Supplier selection is an important component of supply chain management in today’s global competitive environment. Hence, the evaluation and selection of suppliers have received considerable attention in the literature. Many attributes of suppliers, other than cost, are considered in the evaluation and selection process. Therefore, the process of evaluation and selection of suppliers is a multi-criteria decision making process. The methodology adopted to solve the supplier selection problem is intuitionistic fuzzy TOPSIS (Technique for Order Preference by Similarity to the Ideal Solution. Generally, TOPSIS is based on the concept of minimum distance from the positive ideal solution and maximum distance from the negative ideal solution. We examine the deficiencies of using only one metric function in TOPSIS and propose the use of spherical metric function in addition to the commonly used metric functions. For empirical supplier selection problems, more than one metric function should be used.

    The Advanced Toroidal Facility (ATF) is a moderate aspect ratio torsatron that will utilize 53.2 GHz 200 kW Electron Cyclotron Heating (ECH) to produce nearly current-free target plasmas suitable for subsequent heating by strong neutral beam injection. The initial configuration of the ECH system from the gyrotron to ATF consists of an optical arc detector, three bellows, a waveguide mode analyzer, two TiO 2 mode absorbers, two 90 0 miter bends, two waveguide pumpouts, an insulating break, a gate valve, and miscellaneous straight waveguide sections feeding a launcher radiating in the TE 02 mode. Later, a focusing Vlasov launcher will be added to beam the ECH power to the saddle point in ATF magnetic geometry for optimum power deposition. The ECH system has several unique features; namely, the entire ECH system is evacuated, the ECH system is broadband, forward power is monitored by a newly developed waveguide mode analyzer, phase correcting miter bends will be employed, and the ECH system will be capable of operating short pulse to cw. Initial high-power tests show that the overall system efficiency is 87%. The waveguide mode analyzer shows that the gyrotron mode output consists of 13% TE 01 , 82.6% TE 02 , 2.5% TE 03 , and 1.9% TE 04 . 4 refs

    The durability of industrial tissue is a necessary condition, and certainly the most important, for the performance of actual park and the successful of its renewal. Reciprocally, the maintenance and the evolution of the actual park, the preparation of its renewal, are sources of activities to insure this durability of industrial and favour their international development. In the period of reduced activity, which began for the nuclear market, the dialogue which has always existed between EDF and its suppliers must be reinforced, in the respect of their respective responsibility, to insure: a right reciprocal understanding of activities and strategies, a right adaptation to these activities, and finally, the maintenance of the competitiveness.

    Full Text Available Purpose: The research explores and examines factors for supplier evaluation and its impact on process improvement particularly aiming on a steel pipe manufacturing firm in Gujarat, India. Design/Methodology/approach: The conceptual research framework was developed and hypotheses were stated considering the analysis of literature and discussions with the managers and engineers of a steel pipe manufacturing company in Gujarat, India. Data was collected using in-depth interview. The questionnaire primarily involves the perception of evaluation of supplier. Factors influencing supplier evaluation and its influence on process improvement is also examined in this study. The model testing and validation was done using partial least square method. Outcomes signified that the factors that influence evaluation of the supplier are quality, cost, delivery and supplier relationship management. Findings: The study depicted that quality and cost factors for supplier evaluation are insignificant. The delivery and supplier relationship management have significant influence on evaluation of the supplier. The research also depicted that supplier evaluation has significant influence on process improvement. Research limitations/implications: The study has been made specifically for ABC steel pipe manufacturing industry in Gujarat, India and may not be appropriate to the other industries or any parts of the world. There is a possibility of response bias as the conclusions of this research was interpreted on survey responses taken from the employees of case study company, so it is suggested that future research can overcome this problem by employing various methodologies in addition to surveys like carrying out focus group and in-depth interviews, brainstorming sessions with the experts etc. Originality/value: Many researchers have considered quality, cost and delivery as the factors for evaluating the suppliers. But for a company it is quintessential to have good

    Full Text Available The key supplier relationship management represents a vital organizational process. Companies should pay attention not only to managing customer relationships but also to managing relationships with suppliers in order to perform well. They should identify the extent to which a certain supplier adds value through the procurement process. In this line of reasoning, both theory and practice make a distinction between strategic (key and non-strategic (transactional suppliers. By employing the segmentation of the supply market, companies balance their supplier portfolio and are capable of identifying the key suppliers. They can also develop specific programs and initiatives that are aimed at preserving these relationships. In the empirical part of the paper, a survey was conducted on a sample of 123 medium-sized and large Croatian manufacturing companies. The structural model involving the relationship between the key supplier relationship management and value-oriented purchasing was tested. The results indicate that there is a statistically direct, positive and significant relationship between these two constructs. Likewise, the results stress that a theoretical conceptualization and operationalization of the key supplier relationship management construct is both valid and justified. Finally, the theoretical and practical implications and limitations of this study are offered.

  7. Solid and liquid Equation of state for initially porous aluminum where specific heat is constant

    2011-06-01

    A porous solid's initial state is off the thermodynamic surface of the non-porous solid to start with but when pressure is high enough to cause total pore collapse or crush up, then the final states are on the condensed matter thermodynamic surfaces. The Hugoniot for the fully compacted solid is above the Principle Hugoniot with pressure, temperature and internal energy increased at a given v. There are a number of ways to define this hotter Hugoniot, which can be referenced to other thermodynamic paths on this thermodynamic surface. The choice here was to use the Vinet isotherm to define a consistent thermodynamic surface for the solid and melt phase of 6061 aluminum where specific heat is constant for the P-v-T space of interest. Analytical equations are developed for PH and TH.

    At the third awards ceremony to honour its top suppliers, the CMS collaboration presented awards to eight firms. Seven of them are involved in the manufacture of the magnet. The winners of the third CMS suppliers' awards visit the assembly site for the detector. Unsurprisingly, the CMS magnet was once again in the limelight at the third awards ceremony in honour of the collaboration's top suppliers. 'Unsurprisingly', because this magnet, which must produce an intense field of 4 Tesla inside an enormous volume (12 metres in diameter and 13 metres in length) is the detector's key component. As a result, many firms are involved in its construction. The CMS suppliers' awards are an annual event aimed at rewarding the exceptional efforts of certain companies. Firms are only eligible once they have delivered at least 50% of their supplies. This year, the collaboration honoured eight firms at a ceremony held on Monday 4 March in the main auditorium.

    Early in 1989, the Virginia Power purchasing department decided that a different approach was needed for resolving supplier partnering issues and to motivate the supplier to perform as promised to purchase order requirements. Purchasing formed task teams composed of purchasing personnel and requested that they investigate and evaluate alternative methods of order administration and supplier communications. The task teams were asked to research the feasibility of using a reward/penalty approach or to suggest an alternative method to motivate results. The task teams determined that the root cause of the problems for the identified areas of concern was that purchasing personnel and supplier personnel neither communicated well nor fully understood the effect that their actions or inactions had on each other

  16. Households' switching behavior between electricity suppliers in Sweden

    Ek, Kristina; Soederholm, Patrik [Economics Unit, Luleaa University of Technology, 971 87 Luleaa (Sweden)

    2008-12-15

    The overall purpose of this paper is to analyze the factors affecting households' decisions to: (a) switch to a new electricity supplier; and (b) actively renegotiate the electricity contract with the prevailing supplier. The study is based on 536 survey responses from Swedish households and they are analyzed econometrically using probit regression techniques. The analysis is based on a theoretical framework, which embraces both economic and psychological motives behind household decision-making. The results show that households that anticipate significant economic benefits from choosing a more active behavior are also more likely to purse this, while those with smaller potential gains (e.g., households without electric heating) are less likely to change supplier and/or renegotiate their contracts. The impact of overall electricity costs and knowledge about these is particularly important for the latter decision, while respondents that perceive relatively high search and information costs are less likely to switch to an alternative electricity supplier. Moreover, constraints on time, attention, and the ability to process information, may lead to optimizing analyses being replaced by imprecise routines and rules of thumb, and the benefits of the status quo appear to represent one of those simplifying rules. This also opens up for other influences on households' activity such as social interaction and media discourses that raise the attention level. Our results show that these influences are more likely to affect households' choice to switch to new service providers, i.e., the one area of the two investigated here that put the most demand on people's ability to search for and process information.

  20. Supplier Selection Using Weighted Utility Additive Method

    Science.gov (United States)

    Karande, Prasad; Chakraborty, Shankar

    2015-10-01

    Supplier selection is a multi-criteria decision-making (MCDM) problem which mainly involves evaluating a number of available suppliers according to a set of common criteria for choosing the best one to meet the organizational needs. For any manufacturing or service organization, selecting the right upstream suppliers is a key success factor that will significantly reduce purchasing cost, increase downstream customer satisfaction and improve competitive ability. The past researchers have attempted to solve the supplier selection problem employing different MCDM techniques which involve active participation of the decision makers in the decision-making process. This paper deals with the application of weighted utility additive (WUTA) method for solving supplier selection problems. The WUTA method, an extension of utility additive approach, is based on ordinal regression and consists of building a piece-wise linear additive decision model from a preference structure using linear programming (LP). It adopts preference disaggregation principle and addresses the decision-making activities through operational models which need implicit preferences in the form of a preorder of reference alternatives or a subset of these alternatives present in the process. The preferential preorder provided by the decision maker is used as a restriction of a LP problem, which has its own objective function, minimization of the sum of the errors associated with the ranking of each alternative. Based on a given reference ranking of alternatives, one or more additive utility functions are derived. Using these utility functions, the weighted utilities for individual criterion values are combined into an overall weighted utility for a given alternative. It is observed that WUTA method, having a sound mathematical background, can provide accurate ranking to the candidate suppliers and choose the best one to fulfill the organizational requirements. Two real time examples are illustrated to prove

    Kuo-Ping Lin

    2017-12-01

    Full Text Available A decision model for selecting a suitable supplier is a key to reducing the environmental impact in green supply chain management for high-tech companies. Traditional fuzzy weight average (FWA adopts linguistic variable to determine weight by experts. However, the weights of FWA have not considered the public voice, meaning the viewpoints of consumers in green supply chain management. This paper focuses on developing a novel decision model for green supplier selection in the One Belt and One Road (OBOR initiative through a fuzzy weighted average approach with social media. The proposed decision model uses the membership grade of the criteria and sub-criteria and its relative weights, which consider the volume of social media, to establish an analysis matrix of green supplier selection. Then, the proposed fuzzy weighted average approach is considered as an aggregating tool to calculate a synthetic score for each green supplier in the Belt and Road initiative. The final score of the green supplier is ordered by a non-fuzzy performance value ranking method to help the consumer make a decision. A case of green supplier selection in the light-emitting diode (LED industry is used to demonstrate the proposed decision model. The findings demonstrate (1 the consumer’s main concerns are the “Quality” and “Green products” in LED industry, hence, the ranking of suitable supplier in FWA with social media information model obtained the difference result with tradition FWA; (2 OBOR in the LED industry is not fervently discussed in searches of Google and Twitter; and (3 the FWA with social media information could objectively analyze the green supplier selection because the novel model considers the viewpoints of the consumer.

    1990-01-01

    The emergence of new supplier states of nuclear technology within the Third World has raised concern, if those nuclear supplier states will promote an unrestricted and uncontrolled transfer of nuclear technology to developing countries and augment the risk of nuclear weapons proliferation. The article analyses the nuclear export capacities, nuclear exports and the export policy of Argentina, Brazil and India. Argentina is considered as the most important emerging nuclear supplier state in the Third World. Nuclear exports have to be authorisized by the government in all three states and will be covered by IAEA-safeguards in the recipient country. The three states will exercise restraint in the transfer of sensitive nuclear technology. Nuclear exports of Argentina, Brazil and India so far will not augment the danger of nuclear weapons proliferation. (orig./HSCH) [de

  8. Supplier Evaluation Process by Pairwise Comparisons

    Full Text Available We propose to assess suppliers by using consistency-driven pairwise comparisons for tangible and intangible criteria. The tangible criteria are simpler to compare (e.g., the price of a service is lower than that of another service with identical characteristics. Intangible criteria are more difficult to assess. The proposed model combines assessments of both types of criteria. The main contribution of this paper is the presentation of an extension framework for the selection of suppliers in a procurement process. The final weights are computed from relative pairwise comparisons. For the needs of the paper, surveys were conducted among Polish managers dealing with cooperation with suppliers in their enterprises. The Polish practice and restricted bidding are discussed, too.

    The number of states capable of exporting nuclear material, technology, equipment, and services is large and growing. Once confined primarily to states party to the Nuclear Non-Proliferation Treaty (NPT), the list of actual and potential nuclear suppliers now includes many countries that do not subscribe to the NPT or to other international nuclear export control agreements. Although international control accords---such as the Nuclear Exporters' (Zangger) Committee and the London Nuclear Suppliers Group (NSG) guidelines---do not prohibit the export of sensitive nuclear materials and equipment, they do reduce the risks of proliferation by imposing international safeguards as a condition for export. The purpose of this book---the culmination of one phase of an ongoing international research project on the emerging nuclear suppliers and nonproliferation---is to remedy, at least in part, this data deficiency

    In 2011/12, JET started operation with its new ITER-Like Wall (ILW) made of a tungsten (W) divertor and a beryllium (Be) main chamber wall. The impact of the new wall material on the JET Ion Cyclotron Resonance Frequency (ICRF) operation was assessed and also the properties of JET plasmas heated with ICRF were studied. No substantial change of the antenna coupling resistance was observed with the ILW as compared with the carbon wall. Heat-fluxes on the protecting limiters close the antennas quantified using Infra-Red (IR) thermography (maximum 4.5 MW/m{sup 2} in current drive phasing) are within the wall power load handling capabilities. A simple RF sheath rectification model using the antenna near-fields calculated with the TOPICA code can well reproduce the heat-flux pattern around the antennas. ICRF heating results in larger tungsten and nickel (Ni) contents in the plasma and in a larger core radiation when compared to Neutral Beam Injection (NBI) heating. Some experimental facts indicate that main-chamber W components could be an important impurity source: the divertor W influx deduced from spectroscopy is comparable when using RF or NBI at same power and comparable divertor conditions; the W content is also increased in ICRF-heated limiter plasmas; and Be evaporation in the main chamber results in a strong and long lasting reduction of the impurity level. The ICRF specific high-Z impurity content decreased when operating at higher plasma density and when increasing the hydrogen concentration from 5% to 20%. Despite the higher plasma bulk radiation, ICRF exhibited overall good plasma heating efficiency; The ICRF power can be deposited at plasma centre and the radiation is mainly from the outer part of the plasma. Application of ICRF heating in H-mode plasmas started, and the beneficial effect of ICRF central electron heating to prevent W accumulation in the plasma core could be observed.

    1999-11-15

    The sorption of hydrogen sulfide was studied on activated carbons of various origins by means of inverse gas chromatography at infinite dilution. The conditions of the experiment were dry and anaerobic. Prior to the experiments the surface of some carbon samples was oxidized using either nitric acid or ammonium persulfate. Then the structural parameters of carbons were evaluated from the sorption of nitrogen. From the IGC experiments at various temperatures, heats of adsorption were calculated. The results showed that the heat of H{sub 2}S adsorption under dry anaerobic conditions does not depend on surface chemistry. The dependence of the heat of adsorption on the characteristic energy of nitrogen adsorption calculated from the Dubinin-Raduskevich equation was found.

    Full Text Available An efficiency of the heat exchange equipment and reducing their weight and size parameters can be considerably improved by using the optimal methods of heat transfer enhancement, which include a two-dimensional roughness, i.e. ribs, backward-facing steps, cavities, etc. deposited on the heat transfer surface. Their shape, sizes and positional relationship have a significant impact on the structure of the boundary layer and its exchange processes.As known, the most affordable and effective method of controlled influence on the structure of turbulent flow is to create a separation zone or other organized vortex structure in it. In order to successfully use the separation zone, it is necessary to know the mechanism of their interaction with the main turbulent flow and the mechanism of the process in separation zone itself. Heat transfer enhancement is provided mainly due to roughness impact on hydrodynamics of turbulent flow, if the rib height h does not exceed the thickness of the viscous sublayer, since heat transfer enhancement arises from breaking and destruction of viscous sublayer produced by the roughness ribs and emerging vortex zones – sources of turbulence. Usually, the height of ribs y+ ≈ 50, and the distance between them along the streamlined surface is 10-20 times greater. The coefficient of friction also increases, but if the height of ribs is sufficiently small and most of them are in the sublayer, the increase of the friction factor will not exceed the increase of the heat transfer coefficient.The paper presents results of experimental investigation of hydrodynamics and heat transfer in the separation zone before and after a rib and in the area of two rectangular ribs with the height of y+ £ 60. The ribs are placed on the flat plate and heated according to the law of qw = const. The structure of turbulent boundary layer from the standpoint of the universal logarithmic law of velocity distribution has been experimentally

    Supply chain management has increased more significance with the impact of globalization. In the present worldwide market, well-managed supply chain is a standout amongst the most vital requirement to be more competitive in the market. For any organization incorporate cement industry, the most critical decision in initial process of supply chain management is to buy products, materials or services from suppliers. So the role of suppliers is irrefutable important in the global aggressive markets. Appropriate decision of supplier selection can lead to reducing cost in supply chain management. However, it is becoming more complex because of existing various criteria and involving the suitable experts in the company to make valid decision in accordance with its criteria. In this study, the supplier selection of an Indonesia’s leading cement company is analyzed by using one of the popular multi-criteria decision making method, Saaty’s analytical network process (ANP). It is employed for the selection of the best alternative among three suppliers of pasted bag. Supplier with the highest rank comes from several major steps from building the relationship between various criteria to rating the alternatives with the help of experts from the company. The results show that, Communication capability, Flexible payment terms, Ability to meet delivery quantities are the most important criteria in the pasted bag supplier selection in Indonesian cement industry with 0.155, 0.110 and 0.1 ANP coefficient respectively. And based on the ANP coefficient values in limit supermatrix, the A2 or supplier 2 had the highest score with 64.7% or 0.13 ANP coefficient.

    2014-02-15

    The in vitro digestion of heated whey protein aggregates having different structure and physicochemical properties was evaluated under simulated gastric conditions. Aggregates were formed by heating whey protein isolates (WPI) at 3-9% w/w initial protein concentration and pH 3.0-7.0. Results showed that high protein concentration led to formation of larger WPI aggregates with fewer remaining monomers. Aggregates formed at high protein concentrations showed slower degradation rate compared to those formed at low protein concentration. The effect of initial protein concentration on peptide release pattern was not apparent. Heating pH was a significant factor affecting digestion pattern. At pH above the isoelectric point, the majority of the proteins involved in the aggregation, and aggregates formed at pH 6.0 were more susceptible to pepsin digestion than at pH 7.0. At acidic conditions, only small amount of proteins was involved in the aggregation and heated aggregates were easily digested by pepsin, while the remaining unaggregated proteins were very resistant to gastric digestion. The potential physiological implication of these results on satiety was discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available In today’s dynamic business environment, firms are required to utilize efficiently and effectively all the useful resources to gain competitive advantage. Supplier development has evolved as an important strategic instrument to improve buyer supplier relationships. For that reason, this study focuses on providing the strategic significance of supplier development approaches to improve business relationships. By using qualitative research method, an integrated framework of supplier development and buyer-supplier relationship development has been tested and validated in a Finnish case company to provide empirical evidence. It particularly investigates how supplier development approaches can develop buyer-supplier relationships. The study present a set of propositions that identify significant supplier development approaches critical for the development of buyer-supplier relationships and develop a theoretical framework that specifies how these different supplier development approaches support in order to strengthen the relationships. The results are produced from an in-depth case study by implementing the proposed research framework. The findings reveal that supplier development strategies i.e., supplier incentives and direct involvements strongly effect in developing buyer-supplier relationships. Further research may focus on considering in-depth investigation of trust and communication factors along with propositions developed in the study to find out general applicability in dynamic business environment. Proposed integrated framework along with propositions is a unique combination of useful solutions for tactical and strategic management’s decision making and also valid for academic researchers to develop supplier development theories.

    A dense (approx. 10 17 cm -3 ) plasma has been heated via the relativistic two-stream instability using a 3 MeV, intense (5 x 10 5 A/cm 2 ) electron beam. Evidence for heating has been obtained with diamagnetic loops, thin-foil witness plates, and a 2-channel, broad-band soft x-ray detector. Measurements of energy loss from the beam using calorimetry techniques have been attempted. The measured strong dependence of heating on beam transverse temperature and the very short interaction length ( 100 ns after the beam pulse are consistent with a plasma temperature <150 eV and line emission near 80 to 90 eV

  14. Sourcing for Quality: Cooperating with a Single Supplier or Developing Two Competing Suppliers?

    Directory of Open Access Journals (Sweden)

    Jingxian Chen

    2016-01-01

    Full Text Available Supplier efforts regarding product quality are an important issue in outsourcing and play a critical role in a manufacturer’s choice of sourcing strategy. Consider a manufacturer that wants to outsource the manufacturing of two substitute products to external suppliers. This paper studies the strategic interactions under two sourcing strategies: single and dual sourcing. A four-stage noncooperative game model is established to describe each member’s decisions. We further propose four decision scenarios: single sourcing with and without manufacturer quality investment sharing and dual sourcing when suppliers cooperate or do not cooperate on quality decisions. By the backward induction approach, we obtain analytical equilibrium solutions for each decision scenario. By comparing each pair of equilibrium profiles, we find that an appropriate proportion of quality investment sharing by the manufacturer can enable a cooperating strategy with a single supplier to be the dominant strategy. When the manufacturer does not want to share or does not want to share a relatively large portion of its supplier’s quality investment, it will always prefer to develop two competing suppliers when the cost of dual sourcing is sufficiently low. However, dual sourcing can be extremely risky for the manufacturer because the suppliers could provide a relatively low product quality level by cooperating on the quality decision to extract the manufacturer’s profit.

    Full Text Available This study sought to determine the factors that contribute to the failure of small and medium enterprises (SMEs in meeting supplier performance standards. Suppliers are faced with the challenge of SMEs failing to meet supplier performance standards because they rely on these providers of products and services, mainly SMEs, for their operations and to ultimately achieve their mandate. The researchers were able to establish the main factors contributing to SME failure in meeting supplier performance standards. These are as follows: unclear specifications and terms of references from suppliers; insufficient information provided to SME suppliers to ensure understanding of requirements; insufficient feedback and support; no support of SME suppliers based on their Black Economic Empowerment (BEE status; limited or no use of business support programs by SME suppliers; and external factors such as access to finance, changes in the economy, and location.

    2000-01-01

    A detailed numerical analysis of initial evolution of thermal stratification in a curved pipe with a finite wall thickness is performed. A primary emphasis of the present study is placed on the investigation of the effect of existence of pipe wall thickness on the evolution of thermal stratification. A simple and convenient numerical method of treating the unsteady conjugate heat transfer in Cartesian as well as non-orthogonal coordinate systems is presented. The proposed unsteady conjugate heat transfer analysis method is implemented in a finite volume thermal-hydraulic computer code based on a cell-centered, non-staggered grid arrangement, the SIMPLEC algorithm and a higher-order bounded convection scheme. Calculations are performed for initial evolution of thermal stratification with high Richardson number in a curved pipe. The predicted results show that the thermally stratified flow and transient conjugate heat transfer in a curved pipe with a specified wall thickness can be satisfactorily analyzed by using the numerical method presented in this paper. As the result, the present analysis method is considered to be effective for the determination of transient temperature distributions in the wall of curved piping system subjected to internally thermal stratification. In addition, the method can be extended to be applicable for the simulation of turbulent flow of thermally stratified fluid

    This paper is focused on the description of changes in the porous structure during fast heating to the activation temperature of the viscose fibres, pyrolysed to different final temperatures. Standard regenerated cellulose fibre structures were tested. Fabrics were subjected to pyrolysis, the samples being heated to final temperatures of 400, 600 and 850 C. Carbon fibres were subsequently heated to activation temperature (850 C) at a rate of 100 C/min, and then the samples were cooled down. The characteristics of obtained carbon preparations were examined. We have defined a level of restructuring and internal ordering of fibres which originated during slow pyrolysis as well as the range of temperature differences of pyrolysis and activation where fast increase of carbon fibre temperature before activation is advantageous for the development of porous structure. It allows for partial release of pores and fast rebuilding of structure accompanied by a considerable number of defects in the carbon matrix with higher reactivity to oxidiser which, in turn, promotes the development of pores in active carbon during oxidation. Temperature difference for viscose carbon fibres is approximately 150-300 C at pyrolysis temperature of 550-700 C.

    Full Text Available Leaf photosynthesis, a major determinant for yield sustainability in rice, is greatly conditioned by high temperature stress during growth. The effect of short-term high temperatures on leaf photosynthesis, stomatal conductance, Fv/Fm, SPAD readings and yield characteristics was studied in two Colombian rice cultivars. Two genotypes, cv. Fedearroz 50 (F50 and cv. Fedearroz 733 (F733 were used in pot experiments with heat stress treatment (Plants were exposed to 40°C for two and half hours for five consecutive days and natural temperature (control treatment. Heat treatments were carried out at the initiation of panicle primordial (IP or grain-filling (GF phases. The results showed that short-term high temperature stress produced a reduction on the photosynthesis rate in both cultivars either IP or GF phases. Similar trends were found on stomatal conductance in all cases due to high temperatures. Although Fv/Fm and SPAD readings were not affected by high temperatures, these variables diminished significantly among phenological phases. 'F733' rice plants showed higher number spikelet sterility due to heat stress treatments. These results seem to indicate that heat-tolerant cultivars of rice is associated with high levels of photosynthesis rate in leaves.

    This paper describes an experimental study of the relationship between coherent vortical structures and the intensity of heat transport in the initial region of a round, free jet. Simultaneous measurements of velocity and temperature were taken with a four-wire combined probe in a jet that was acoustically stimulated with a frequency corresponding to the jet-column mode. The obtained results suggest that the mutual phase relations between oscillatory and random components of velocity and temperature lead to substantial intensification of the radial heat transport. Due to the same reason the longitudinal heat flux does not reveal a significant change in the presence of coherent structures and, as a result, a much wider spread of the temperature field in comparison with velocity may be observed as a characteristic feature of this flow. It was also observed that heat transfer processes are realized in substantial part by random turbulence generated due to the action of coherent motion. (orig.) With 13 figs., 27 refs.

    Coal remains a key feature of the world's energy and steel markets and coal mining is a global industry. Suppliers of equipment to the coal-mining industry have seen traditional markets almost disappear and new markets emerge. Suppliers need to work closely with customers, sometimes in remote areas developing long-term partnerships and continually improving the product to their mutual benefit. An attempt to explain how global changes to the underground coal industry have influenced the supply of coal-mining equipment is illustrated by recent developments in the Long-Airdox group. An example is given of how the group worked with the Cayirhan Mine in Turkey supplying cast armoured face conveyors for longwall mining. The paper was presented at a meeting of the Nottinghamshire Branch of the Institution of Mining and Metallurgy on 3 June 1998 in Nottinghamshire, UK. 1 fig.

    2009-01-01

    Plasma facing components (PFCs) in magnetic confinement controlled fusion machines are armoured with carbon fibre composite (CFC) bonded to a copper alloy heat sink. The manufacturing process induces high level of residual stresses due to the thermal expansion mismatch between CFC and copper and PFCs have to withstand strong stress ranges during operation. To study the initiation and propagation of damage in the CFC part, the ONERA damage model is used to describe the behaviour of the N11 material. The finite element simulations show that the damage is located near the interface and develops during the manufacturing of the PFCs as a consequence of the high amplitude of shear stresses. Under high heat flux, stresses decrease and the damage does not evolve. Further studies will take into account the damageable behaviour of the composite/copper interface, which will lead to geometrical optimisations and better knowledge of the link between damage and conductivity.

  15. Partners in quality: managing your suppliers.

    Science.gov (United States)

    Conway, B A

    1991-05-01

    Just expecting more from your supplier is not what partnership is about. We have had the experience where the quality improvement and partnership banner has been waved but the tone and spirit of the meeting did not encourage or support a joint quality improvement effort. Benefits will not be achieved until the wall truly begins to come apart and the relationship is built on mutual respect and trust. Data collection and open answers to questions often reveal embarrassing errors and obvious needs for improvements. As stated before, blame and finger-pointing must be replaced with a mutual commitment to asking and answering the question, "How can we improve?" As Dr. W. Edwards Deming has stated, "End the practice of awarding business on the basis of price tag. Instead, minimize total cost. Move toward a single supplier for any one item on a long-term relationship of loyalty and trust." The structured approach of a quality improvement process and the application of quality methods and techniques has proven useful in removing emotion and helping the team focus on the process rather than the people and the issues involved. Quality improvement methods are focused on achieving both customer and supplier goals--customer satisfaction, employee satisfaction, and operational efficiency and effectiveness. Our experience with Partners in Quality as well as our experience with the quality leadership process supports a recent quote in the Harvard Business Review: "Quality is not just a slogan...(it is) the most profitable way to run a business."

    2012-02-01

    Several factors were studied as affecting protein degradation and texture of skipjack tuna muscle following ambient pressure thermal processing (precooking). These included degree of mushy tuna syndrome (MTS) evidenced in the raw meat, raw meat pH, abusive thawing/holding, and precooking temperature/time. Slurries and intact pieces from frozen skipjack tuna, either tempered for 2 h or thawed and held at 25 °C for 22 h (abusive treatment) were heated at temperatures ranging from 40 to 80 °C for up to 2 h, and also at 90 °C for 1 h, with or without prior adjustment of pH to 5 or 7 to favor cathepsin or calpain activity, respectively. Proteolysis of precooked samples was monitored by Lowry assay and SDS-PAGE; cooked texture of intact meat was measured using a Kramer shear press and by sensory profile analysis. Proteolysis maximally occurred in slurries of skipjack tuna muscle that had been abusively stored (22 h at 25 °C) and adjusted to pH 5 prior to heating at 55 °C. Intact pieces of tuna abusively thawed/held for 22 h with subsequent heating at 55 °C also evidenced the most proteolysis and were the least firm in texture. Raw fish that evidenced higher severity of MTS when raw displayed higher levels of proteolysis prior to cooking, which were further increased after cooking at 55 °C. The kinetic data presented here can be used to optimize processing conditions for skipjack tuna canning to minimize textural degradation and optimize quality. © 2012 Institute of Food Technologists®

    2010-01-01

    A vacuum heat pretreatment is applied, in order to enhance the reactivity of hydride-forming metals towards hydrogen reaction. For gadolinium, as for other rare-earth metals and some actinides, pretreatment temperatures of about 470 K are sufficient to induce such activation. The different factors that may be involved in that activation mechanism are identified and analyzed for gadolinium and their role is evaluated. It is concluded that the most prominent effect is desorption of surface hydroxyl groups, which impede the dissociative chemisorptions of hydrogen.

    Full Text Available Increasing reliance on outsourcing has made supplier selection a critical success factor for a supply chain/network. In addition to cost, the synergy among product components and supplier selection criteria should be considered holistically during the supplier selection process. This paper shows this synergy using coupled-attribute analysis. The key coupling attributes, including total cost, quality, delivery reliability, and delivery lead time of the final product, are identified and formulated. A max-max model is designed to assist the selection of the optional combination of suppliers. The results are compared with the individual supplier selection. Management insights are also discussed.

    2016-01-01

    A mathematical model of fractional order two-temperature generalized thermoelasticity with diffusion and initial stress is proposed to analyze the transient wave phenomenon in an infinite thermoelastic half-space. The governing equations are derived in cylindrical coordinates for a two dimensional axi-symmetric problem. The analytical solution is procured by employing the Laplace and Hankel transforms for time and space variables respectively. The solutions are investigated in detail for a time dependent heat source. By using numerical inversion method of integral transforms, we obtain the solutions for displacement, stress, temperature and diffusion fields in physical domain. Computations are carried out for copper material and displayed graphically. The effect of fractional order parameter, two-temperature parameter, diffusion, initial stress and time on the different thermoelastic and diffusion fields is analyzed on the basis of analytical and numerical results. Some special cases have also been deduced from the present investigation.

    2013-09-01

    This paper elaborates the importance of evaluating supplier quality performance to an organization. Supplier quality performance evaluation reflects the actual performance of the supplier exhibited at customer's end. It is critical in enabling the organization to determine the area of improvement and thereafter works with supplier to close the gaps. Success of the customer partly depends on supplier's quality performance. Key criteria as quality, cost, delivery, technology support and customer service are categorized as main factors in contributing to supplier's quality performance. 18 suppliers' who were manufacturing automotive application parts evaluated in year 2010 using weight point system. There were few suppliers with common rating which led to common ranking observed by few suppliers'. Analytical Hierarchy Process (AHP), a user friendly decision making tool for complex and multi criteria problems was used to evaluate the supplier's quality performance challenging the weight point system that was used for 18 suppliers'. The consistency ratio was checked for criteria and sub-criteria. Final results of AHP obtained with no overlap ratings, therefore yielded a better decision making methodology as compared to weight point rating system.

    2017-08-01

    Full Text Available Supplier evaluation and selection are fundamental tasks since they are part of the production process and even initiate the supply chain (SC. Despite their importance in the production system, supplier evaluation and selection may be challenging activities to be performed if companies look at the wide range of available evaluation techniques and methodologies, which now seek to integrate both traditional and green attributes. In addition, companies may refuse to take into account green attributes during the supplier selection process, because they do not know their impact on commercial benefits. To overcome this limitation, this study examines the Mexican manufacturing sector and measures the impact of supplier traditional attributes and green attributes on business performance, namely production process benefits and commercial benefits. As data collection instrument, we administered a survey to 253 supplier evaluators and selectors; then, using the gathered data, we constructed a structural equation model. The model includes four variables to determine the impact of traditional and green attributes on business performance: green attributes, traditional attributes, production process benefits, and commercial benefits. The results indicate that all the latent variables have positive direct effects on one another. For instance, process benefits show the largest effects on commercial benefits, but the most significant effect is caused by traditional attributes on commercial benefits through green attributes and production process benefits.

  12. Use of ICRH for startup and initial heating of the TMX-U central cell

    International Nuclear Information System (INIS)

    Molvik, A.W.; Falabella, S.

    1982-05-01

    Ion cyclotron resonance heating (ICRH) was evaluated and it was found to be satisfactory for use in establishing the conditions necessary to form a thermal barrier in TMX-upgrade (TMX-U). We discuss the constraints that must be satisfied in order to maintain a plasma, and outline a complete startup scenario that ends with the plasma at design parameters. The detailed discussions in this report concentrate on those parts of startup where ICRH is necessary. The ability of ICRH to couple power into a plasma at the fundamental ion cyclotron resonance, w/sub ci/, is determined from experiments with a half-turn loop antenna in the Phaedrus tandem mirror central cell. From these experiments, we get the empirical scaling that shows power deposited in the plasma is proportional to the plasma density

    2018-05-01

    This study uses a global land-atmosphere coupled model, the land-atmosphere component of the Global Seasonal Forecast System version 5, to quantify the degree to which soil moisture initialization could potentially enhance boreal summer surface air temperature forecast skill. Two sets of hindcast experiments are performed by prescribing the observed sea surface temperature as the boundary condition for a 15-year period (1996-2010). In one set of the hindcast experiments (noINIT), the initial soil moisture conditions are randomly taken from a long-term simulation. In the other set (INIT), the initial soil moisture conditions are taken from an observation-driven offline Land Surface Model (LSM) simulation. The soil moisture conditions from the offline LSM simulation are calibrated using the forecast model statistics to minimize the inconsistency between the LSM and the land-atmosphere coupled model in their mean and variability. Results show a higher boreal summer surface air temperature prediction skill in INIT than in noINIT, demonstrating the potential benefit from an accurate soil moisture initialization. The forecast skill enhancement appears especially in the areas in which the evaporative fraction—the ratio of surface latent heat flux to net surface incoming radiation—is sensitive to soil moisture amount. These areas lie in the transitional regime between humid and arid climates. Examination of the extreme 2003 European and 2010 Russian heat wave events reveal that the regionally anomalous soil moisture conditions during the events played an important role in maintaining the stationary circulation anomalies, especially those near the surface.

    2015-11-01

    Full Text Available Background: Products in corner stores may be affected by the network of suppliers from which storeowners procure food and beverages. To date, this supplier network has not been well characterized. Methods: Using network analysis, we examined the connections between corner stores (n = 24 in food deserts of Baltimore City (MD, USA and their food/beverage suppliers (n = 42, to determine how different store and supplier characteristics correlated. Results: Food and beverage suppliers fell into two categories: Those providing primarily healthy foods/beverages (n = 15 in the healthy supplier network (HSN and those providing primarily unhealthy food/beverages (n = 41 in the unhealthy supplier network (UHSN. Corner store connections to suppliers in the UHSN were nearly two times greater (t = 5.23, p < 0.001, and key suppliers in the UHSN core were more diverse, compared to the HSN. The UHSN was significantly more cohesive and densely connected, with corner stores sharing a greater number of the same unhealthy suppliers, compared to HSN, which was less cohesive and sparsely connected (t = 5.82; p < 0.001. Compared to African Americans, Asian and Hispanic corner storeowners had on average −1.53 (p < 0.001 fewer connections to suppliers in the HSN (p < 0.001. Conclusions: Our findings indicate clear differences between corner stores’ HSN and UHSN. Addressing ethnic/cultural differences of storeowners may also be important to consider.

  2. Opportunities for suppliers in the North Sea

    International Nuclear Information System (INIS)

    D'Ancona, J.E.

    1992-01-01

    If European suppliers to the offshore industry are to prosper, it has to be on the basis of a single internationally competitive North Sea market. If we continue to talk and think in terms of a British sector, a Norwegian sector, Dutch and Danish sectors, then we will inhibit the full development of contractors and suppliers. The long term future in oilfield supplies lies in a mixed portfolio of international projects. Oil and gas exploration and development, particularly offshore, is notoriously cyclical. To survive the downturns in one market supply, companies need to have access to the upswing in others. The significance of a single North Sea market is that it presents an international arena for the best companies to demonstrate their technical and commercial abilities. Individual national sectors do not - cannot - provide that opportunity to anything like the same extent. Taking then the North Sea as a single competitive market, it represents the most important offshore area in the world at the present time, and this is likely to continue during the 1990s. The prospects of achieving a single North Sea market are discussed. (author)

  4. A Fuzzy MCDM Approach to Evaluate Green Suppliers

    Directory of Open Access Journals (Sweden)

    Gizem Cifci

    2011-10-01

    Full Text Available Nowadays the effect of industrial production on the environment brought out the importance of the green concept in supply chains. Particularly for supplier firms, greening is essential in a supply chain because with growing worldwide awareness of environmental protection, green production has become an important theme for almost every manufacturer. While literature related to supplier evaluation is plentiful, the works on green supplier evaluation are rather limited. Therefore, a green supplier evaluation model is proposed in this study. Due to its multi-criteria nature, the green supplier evaluation process requires an appropriate multi criteria analysis and solution approach. Selecting a proper method involves an insight analysis among available multi-criteria decision making (MCDM techniques. Among numerous methods of MCDM, this paper presents a decision framework based on group decision making (GDM and fuzzy analytic hierarchy process (FAHP for evaluating and selecting green suppliers. The applicability of the proposed approach is verified through a case study.

    The research on service supply chain has attracted more and more focus from both academia and industrial community. In a service supply chain, the selection of supplier portfolio is an important and difficult problem due to the fact that a supplier portfolio may include multiple suppliers from a variety of fields. To address this problem, we propose a novel supplier portfolio selection method based on a well known machine learning approach, i.e., Ranking Neural Network (RankNet). In the proposed method, we regard the problem of supplier portfolio selection as a ranking problem, which integrates a large scale of decision making features into a ranking neural network. Extensive simulation experiments are conducted, which demonstrate the feasibility and effectiveness of the proposed method. The proposed supplier portfolio selection model can be applied in a real corporation easily in the future.

    Full Text Available The performance of the supplier is a crucial factor for the success or failure of any company. Rational and effective decision making in terms of the supplier selection process can help the organization to optimize cost and quality functions. The nature of supplier selection processes is generally complex, especially when the company has a large variety of products and vendors. Over the years, several solutions and methods have emerged for addressing the supplier selection problem (SSP. Experience and studies have shown that there is no best way for evaluating and selecting a specific supplier process, but that it varies from one organization to another. The aim of this research is to demonstrate how a multiple attribute decision making approach can be effectively applied for the supplier selection process.

    The dependence of divertor particle and power deposition widths on plasma current (I_p) for lower hybrid current driven (LHCD) L- and H-mode plasmas was initially studied in the Experimental Advanced Superconducting Tokamak (EAST) under a lower single null (LSN) divertor configuration. And the profile widths were obtained from the divertor triple Langmuir probe array and an infra-red (IR) camera. It is shown that the deposition widths of divertor particle and heat flux profiles both display a strong negative dependence on increasing plasma current, in L-mode, ELM-free H-mode and ELMy H-mode scenarios. The experimental results show good agreement with the heuristic SOL width model proposed by Goldston. (author)

    Lewis A. Dunn, a former Assistant Director of the US Arms Control and Disarmament Agency and now a senior analyst with Science Applications International Corporation, looks to the future to offer "The Emerging Nuclear Suppliers: Some Guidelines for Policy ." Mr. Dunn notes that although most emerging suppliers are cautious, many are not party to existing nonproliferation treaties. He calls upon the nonproliferation community to continue the present policy of not supporting unsafeguarded nuclear activities. He suggests that the nonproliferation community work within existing standards and infrastructures of nuclear suppliers to convince emerging supplier nations of the merits of nuclear export control.

  13. Multiattribute Supplier Selection Using Fuzzy Analytic Hierarchy Process

    2010-11-01

    Full Text Available Supplier selection is a multiattribute decision making (MADM problem which contains both qualitative and quantitative factors. Supplier selection has vital importance for most companies. The aim of this paper is to provide an AHP based analytical tool for decision support enabling an effective multicriteria supplier selection process in an air conditioner seller firm under fuzziness. In this article, the Analytic Hierarchy Process (AHP under fuzziness is employed for its permissiveness to use an evaluation scale including linguistic expressions, crisp numerical values, fuzzy numbers and range numerical values. This scale provides a more flexible evaluation compared with the other fuzzy AHP methods. In this study, the modified AHP was used in supplier selection in an air conditioner firm. Three experts evaluated the suppliers according to the proposed model and the most appropriate supplier was selected. The proposed model enables decision makers select the best supplier among supplier firms effectively. We confirm that the modified fuzzy AHP is appropriate for group decision making in supplier selection problems.

    This paper aims to develop an analytical study of heat propagation in biological tissues for constant and variable heat flux at the skin surface correlated with Hyperthermia treatment. In the present research work we have attempted to impose two unique kind of oscillating boundary condition relevant to practical aspect of the biomedical engineering while the initial condition is constructed as spatially dependent according to a real life situation. We have implemented Laplace's Transform method (LTM) and Green Function (GFs) method to solve single phase lag (SPL) thermal wave model of bioheat equation (TWMBHE). This research work strongly focuses upon the non-invasive therapy by employing oscillating heat flux. The heat flux at the skin surface is considered as constant, sinusoidal, and cosine forms. A comparative study of the impact of different kinds of heat flux on the temperature field in living tissue explored that sinusoidal heat flux will be more effective if the time of therapeutic heating is high. Cosine heating is also applicable in Hyperthermia treatment due to its precision in thermal waveform. The result also emphasizes that accurate observation must be required for the selection of phase angle and frequency of oscillating heat flux. By possible comparison with the published experimental research work and published mathematical study we have experienced a difference in temperature distribution as 5.33% and 4.73%, respectively. A parametric analysis has been devoted to suggest an appropriate procedure of the selection of important design variables in viewpoint of an effective heating in hyperthermia treatment.

    Nuclear materials must be delivered by either the manufacturer or the distributor with objective, documented evidence that the material was manufactured, inspected, and tested by proven techniques performed by qualified personnel working to documented procedures. Measurement devices used for acceptance must be of proven accuracy. The material and all records must be identified for positive traceability as part of the quality history of the nuclear components, system, or structure in which the material was used. In conclusion, the nuclear material supplier must join the fabricator, the installer, and the user in effective implementation of the total systems approach to the application of quality assurance principles to all phases of procurement, fabrication, installation, and use of the safety-related components, systems, and structures in a nuclear power plant

    The concept of attraction is not reserved for the study of interpersonal relationships between husband and wife, family members, or lifelong friends. On the contrary, it contains much potential as a variable describing interpersonal business exchange relationships. This potential has been noted...... by well-known industrial marketing scholars in the past, and recent theoretical advances have incorporated attraction to describe buyer– supplier exchange, although primarily at the interorganizational level of analysis. The in-depth understanding of interpersonal attraction between boundary spanners...... representing buying and supply companies has yet to be developed. By drawing on social psychology and social exchange literature, this paper attempts to fill some of this gap. It contributes by uncovering the elements and process of interpersonal attraction. Furthermore, propositions are formulated to guide...

    A water-filled differentially heated rotating annulus with initially prepared stable vertical salinity profiles is studied in the laboratory. Based on two-dimensional horizontal particle image velocimetry data and infrared camera visualizations, we describe the appearance and the characteristics of the baroclinic instability in this original configuration. First, we show that when the salinity profile is linear and confined between two non-stratified layers at top and bottom, only two separate shallow fluid layers can be destabilized. These unstable layers appear nearby the top and the bottom of the tank with a stratified motionless zone between them. This laboratory arrangement is thus particularly interesting to model geophysical or astrophysical situations where stratified regions are often juxtaposed to convective ones. Then, for more general but stable initial density profiles, statistical measures are introduced to quantify the extent of the baroclinic instability at given depths and to analyze the connections between this depth-dependence and the vertical salinity profiles. We find that, although the presence of stable stratification generally hinders full-depth overturning, double-diffusive convection can lead to development of multicellular sideways convection in shallow layers and subsequently to a multilayered baroclinic instability. Therefore we conclude that by decreasing the characteristic vertical scale of the flow, stratification may even enhance the formation of cyclonic and anticyclonic eddies (and thus, mixing) in a local sense.

  1. Initial Business Case Analysis of Two Integrated Heat Pump HVAC Systems for Near-Zero-Energy Homes

    Energy Technology Data Exchange (ETDEWEB)

    Baxter, Van D [ORNL

    2006-11-01

    The long range strategic goal of the Department of Energy's Building Technologies (DOE/BT) Program is to create, by 2020, technologies and design approaches that enable the construction of net-zero energy homes at low incremental cost (DOE/BT 2005). A net zero energy home (NZEH) is a residential building with greatly reduced needs for energy through efficiency gains, with the balance of energy needs supplied by renewable technologies. While initially focused on new construction, these technologies and design approaches are intended to have application to buildings constructed before 2020 as well resulting in substantial reduction in energy use for all building types and ages. DOE/BT's Emerging Technologies (ET) team is working to support this strategic goal by identifying and developing advanced heating, ventilating, air-conditioning, and water heating (HVAC/WH) technology options applicable to NZEHs. Although the energy efficiency of heating, ventilating, and air-conditioning (HVAC) equipment has increased substantially in recent years, new approaches are needed to continue this trend. Dramatic efficiency improvements are necessary to enable progress toward the NZEH goals, and will require a radical rethinking of opportunities to improve system performance. The large reductions in HVAC energy consumption necessary to support the NZEH goals require a systems-oriented analysis approach that characterizes each element of energy consumption, identifies alternatives, and determines the most cost-effective combination of options. In particular, HVAC equipment must be developed that addresses the range of special needs of NZEH applications in the areas of reduced HVAC and water heating energy use, humidity control, ventilation, uniform comfort, and ease of zoning. In FY05 ORNL conducted an initial Stage 1 (Applied Research) scoping assessment of HVAC/WH systems options for future NZEHs to help DOE/BT identify and prioritize alternative approaches for further

    This paper proposes a conceptual framework to compare criteria/factor that influence the supplier selection. A mixed methods approach comprising qualitative and quantitative survey will be used. The study intend to identify and define the metrics that key stakeholders at Public Works Department (PWD) believed should be used for supplier. The outcomes would foresee the possible initiatives to bring procurement in PWD to a strategic level. The results will provide a deeper understanding of drivers for supplier’s selection in the construction industry. The obtained output will benefit many parties involved in the supplier selection decision-making. The findings provides useful information and greater understanding of the perceptions that PWD executives hold regarding supplier selection and the extent to which these perceptions are consistent with findings from prior studies. The findings from this paper can be utilized as input for policy makers to outline any changes in the current procurement code of practice in order to enhance the degree of transparency and integrity in decision-making.

    Full Text Available This study examines the types and extent of supplier development activities undertaken by an identified manufacturing firm, along with the importance of supplier development goals. Data was collected through a cross-sectional survey of 26 respondents, consisting of officers, engineers, managers and senior managers from various sections within the buying firm's organisation. The analysis is based primarily on descriptive statistics. The results reveal that the supplier-specific factors are more prominent predictors of the outcomes of the supplier development efforts as compared to the other factors. The manufacturer's focus on the supplier development programme appears to be a short-term, results-oriented approach involving limited or no significant efforts on the side of thebuying firm. There is evidence indicating that the manufacturer has not fully utilised the expertise of its suppliers in designing its products, since there is lack of supplier involvement in the early stages of the design and development activities. The overallresults point to numerous deficiencies in the supplier development programme. Practical implications are provided in light of the findings.

    Nakandala, Dilupa; Lau, Henry; Zhang, Jingjing; Gunasekaran, Angappa

    2018-05-01

    For enterprises, it is imperative that the trade-off between the cost of inventory and risk implications is managed in the most efficient manner. To explore this, we use the common example of a wholesaler operating in an environment where suppliers demonstrate heterogeneous reliability. The wholesaler has partial orders with dual suppliers and uses lateral transshipments. While supplier reliability is a key concern in inventory management, reliable suppliers are more expensive and investment in strategic approaches that improve supplier performance carries a high cost. Here we consider the operational strategy of dual sourcing with reliable and unreliable suppliers and model the total inventory cost where the likely scenario lead-time of the unreliable suppliers extends beyond the scheduling period. We then develop a Customized Integer Programming Optimization Model to determine the optimum size of partial orders with multiple suppliers. In addition to the objective of total cost optimization, this study takes into account the volatility of the cost associated with the uncertainty of an inventory system.

This model can be used in auctions. The supplier selection process becomes complex and difficult on last twenty years since the Internet plays an important role in business management. Companies have to concentrate their efforts on their core activities and the others activities should be realized by outsourcing. They can achieve significant cost reduction by using e-marketplaces in their purchase process and by using decision support systems on supplier selection. In the literature were proposed many approaches for supplier evaluation and selection process. The performance of potential suppliers is evaluated using multi criteria decision making methods rather than considering a single factor cost.

    2018-01-01

    Full Text Available Major construction projects have a great influence on the national economy and society, wherein cooperative relationship between construction suppliers plays an increasingly significant role in the overall supply chain system. However, the relationships between suppliers are noncontractual, multistage, dynamic, and complicated. To gain a deeper insight into the suppliers’ cooperative relationships, an evolutionary game model is developed to explore the cooperation tendency of multisuppliers. A replicator dynamic system is further formulated to investigate the evolutionary stable strategies of multisuppliers. Then, fourteen “when-then” type scenarios are concluded and classified into six different evolutionary tracks. Meanwhile, the critical influencing factors are identified. The results show that the suppliers’ production capacity, owner-supplier contract, and the owner’s incentive mechanism influence the cooperation tendency of suppliers directly. The managerial implications contribute to insightful references for a more stable cooperative relationship between the owner and suppliers.

    U.S. Department of Energy (DOE) sites/contractors purchase several different types of containers (such as boxes, drums, large bulk dump trucks, railcars, cargo containers, burrito wraps, and super sacks) for use in the storage and transportation of low-level waste. These containers are purchased from several suppliers - all of whom must be pre-approved according to DOE rules, orders and guidelines - and the suppliers must manufacture the containers to exact specifications and designs supplied by the DOE site/contractor. DOE studies and qualitative evaluations indicate that the current supplier evaluation process is too costly and inefficient. Therefore, DOE, in coordination with sites/contractors, instituted a corporate approach to centralize the supplier quality evaluation program for the procurement of containers. That effort resulted in the development of this Container Suppler Evaluation Program. The program was implemented when two suppliers were evaluated using this program.

    Full Text Available Supplier selection is one of the most important decisions made in supply chain management. Supplier evaluation problem has been in the center of supply chain researcher’s attention in these years. Managers regard some of these studies and methods inappropriate due to simple, weight scoring methods that generally are based on subjective opinions and judgments of decision maker units involved in the supplier evaluation process yielding imprecise and even unreliable results. This paper seeks to propose a methodology to integrate data envelopment analysis (DEA and group analytical hierarchy process (GAHP for evaluating and selecting the most efficient supplier. We develop a methodology, which consists of 6 steps, one by one has been introduced in lecture and finally applicability of proposed method is indicated by assessing 12 suppliers in a numerical example.

By conducting a literature review and gathering expert opinions, 10 criteria on carbon and energy performance were identified to evaluate low carbon suppliers using the Fuzzy Delphi Method (FDM. Subsequently, the decision-making trial and evaluation laboratory (DEMATEL method was used to determine the importance of evaluation criteria in selecting suppliers and the causal relationships between them. The DEMATEL-based analytic network process (DANP and VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR were adopted to evaluate the weights and performances of suppliers and to obtain a solution under each evaluation criterion. An illustrative example of a hotel company was presented to demonstrate how to select a low carbon supplier according to carbon and energy management. The proposed hybrid model can help firms become effective in facilitating low carbon supply chains in hotels.

    1991-01-01

    Initiation of replication of lambda DNA requires assembly of the proper nucleoprotein complex consisting of the lambda origin of replication-lambda O-lambda P-dnaB proteins. The dnaJ, dnaK and grpE heat shock proteins destabilize the lambda P-dnaB interaction in this complex permitting dnaB helicase to unwind lambda DNA near ori lambda sequence. First step of this disassembling reaction is the binding of dnaK protein to lambda P protein. In this report we examined the influence of dnaJ and grpE proteins on stability of the lambda P-dnaK complex. Our results show that grpE alone dissociates this complex, but both grpE and dnaJ together do not. These results suggest that, in the presence of grpE protein, dnaK protein has a higher affinity for lambda P protein complexed with dnaJ protein than in the situation where grpE protein is not used.

    Full Text Available According to several studies, power and interdependence play a considerable role in understanding the buyer–supplier relationships, yet, empirical research is still limited. Also, the nature of the buyer-supplier relationship and managing them might vary based on the power position of buyers and suppliers. Few studies focused on the reason behind this interrelation and strong influence of power on the buyer-supplier relationships. Thus, the purpose of this study is to gain better understanding and try to identify how power position and buyer-supplier relationships are interrelated, and whether there are common determinants and/or characteristics behind this strong bond between the two concepts. Both transaction cost analysis theory and social exchange theory were integrated in building the argument. Regarding the methodology, qualitative exploratory research design was employed by using multiple-case study as the main research method, where three multinational Egyptian organizations were selected. Moreover, data was collected using individual in-depth interviews, and analyzed through coding and cross case analysis techniques. The results showed that there are common factors that influence both buyer-supplier relationship characteristics and power position attributes. And according, the findings helped in pointing out a new lens of discussing and investigating the bond between buyer-supplier relationships ad power in research.

  6. Contributions to the initial development of a microelectromechanical loop heat pipe, which is based on coherent porous silicon

    Science.gov (United States)

    Cytrynowicz, Debra G.

    The research project itself was the initiation of the development of a planar miniature loop heat pipe based on a capillary wick structure made of coherent porous silicon. Work on this project fell into four main categories, which were component fabrication, test system construction, characterization testing and test data collection, performance analysis and thermal modeling. Component fabrication involved the production of various components for the evaporator. When applicable, these components were to be produced by microelectronic and MEMS or microelectromechanical fabrication techniques. Required work involved analyses and, where necessary, modifications to the wafer processing sequence, the photo-electrochemical etching process, system and controlling computer program to make it more reliable, flexible and efficient. The development of more than one wick production process was also extremely necessary in the event of equipment failure. Work on developing this alternative also involved investigations into various details of the photo-electrochemical etching process itself. Test system construction involved the actual assembly of open and closed loop test systems. Characterization involved developing and administering a series of tests to evaluate the performance of the wicks and test systems. Although there were some indications that the devices were operating according to loop heat pipe theory, they were transient and unstable. Performance analysis involved the construction of a transparent evaporator, which enabled the visual observation of the phenomena, which occurred in the evaporator during operation. It also involved investigating the effect of the quartz wool secondary wick on the operation of the device. Observations made during the visualization study indicated that the capillary and boiling limits were being reached at extremely low values of input power. The work was performed in a collaborative effort between the Biomedical Nanotechnology Research

    Although both 1st harmonic ordinary mode (O1) and 2nd harmonic extra-ordinary mode (X2) have been successfully used to initiate pre-ionization and breakdown in many devices, a complete theoretical model is still missing to explain the success of this method. Moreover, some experimental observations are not completely understood, such as what occurs during the delay time between the turn-on of ECRH power and first signals of density or light measurements. Since during this free period the ECRH power has to be absorbed by in-vessel components, it is of prime importance to know what governs this delay time. Recently, dedicated start-up experiments have been performed on WEGA, using a 28 GHz ECRH system in X2-mode. This machine has the interesting capability to be run also as a tokamak allowing comparative experiments between stellarator (ι/2π > 0) and tokamak (ι/2π = 0) configurations. Different scans in heating power, neutral gas pressure, and rotational transform (ι) show clearly that the start-up is a two step process. A first step following the turn-on of the ECRH power during which no measurable electron density (or just above the noise level in some cases), ECE and radiated power is detected. Its duration depends strongly on the level of injected power. The second step corresponds to the gas ionization and plasma expansion phase, with a velocity of density build-up and filling-up of the vessel volume depending mainly on pressure, gas and rotational transform. Moreover, an interesting scenario of ECRH pre-ionization without loop voltage in tokamak configuration by applying a small optimal vertical field is relevant for start-up assistance on future experiments like ITER. The results from this experimental parametric study are useful for the modeling of the start-up assisted by the second harmonic electron cyclotron resonance heating. The aim of this work is to establish predictive scenarios for both ITER and W7-X operation

    Background The assessment of suppliers of critical goods and services to European blood establishments is a regulatory requirement proving difficult to resource. This study was to establish whether European Blood Alliance member blood services could collaborate to reduce the cost of auditing suppliers without diminishing standards. Materials and method Five blood services took part, each contributing a maximum of one qualified auditor per audit (rather than the usual two). Four audits were completed involving eight auditors in total to a European Blood Alliance agreed policy and process using an audit scope agreed with suppliers. Results Audits produced a total of 22 observations, the majority relating to good manufacturing practice and highlighted deficiencies in processes, procedures and quality records including complaints’ handling, product recall, equipment calibration, management of change, facilities’ maintenance and monitoring and business continuity. Auditors reported that audits had been useful to their service and all audits prompted a positive response from suppliers with satisfactory corrective action plans where applicable. Audit costs totalled € 3,438 (average € 860 per audit) which is no more than equivalent traditional audits. The four audit reports have been shared amongst the five participating blood establishments and benefitted 13 recipient departments in total. Previously, 13 separate audits would have been required by the five blood services. Discussion Collaborative supplier audit has proven an effective and efficient initiative that can reduce the resource requirements of both suppliers and individual blood service’s auditing costs. Collaborative supplier audit has since been established within routine European Blood Alliance management practice. PMID:24553596

    Dust accumulation in the components of heating, ventilation, and air-conditioning (HVAC) systems is a potential source of contaminants. To date, very little information is available on recognized methods for assessing dust buildup in these systems. The few existing methods are either objective in nature, involving numerical values, or subjective in nature, based on experts' judgments. An earlier project aimed at assessing different methods of sampling dust in ducts was carried out in the laboratories of the Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST). This laboratory study showed that all the sampling methods were practicable, provided that a specific surface-dust cleaning initiation criterion was used for each method. However, these conclusions were reached on the basis of ideal conditions in a laboratory using a reference dust. The objective of this present study was to validate these laboratory results in the field. To this end, the laboratory sampling templates were replicated in real ducts and the three sampling methods (the IRSST method, the method of the U.S. organization National Air Duct Cleaner Association [NADCA] and that of the French organization Association pour la Prévention et l'Étude de la Contamination [ASPEC]) were used simultaneously in a statistically representative number of systems. The air return and supply ducts were also compared. Cleaning initiation criteria under real conditions were found to be 6.0 mg/100 cm(2) using the IRSST method, 2.0 mg/100 cm(2) using the NADCA method, and 23 mg/100 cm(2) using the ASPEC method. In the laboratory study, the criteria using the same methods were 6.0 for the IRSST method, 2.0 for the NADCA method, and 3.0 for the ASPEC method. The laboratory criteria for the IRSST and NADCA methods were therefore validated in the field. The ASPEC criterion was the only one to change. The ASPEC method therefore allows for the most accurate evaluation of dust accumulation in HVAC

    When the then-26 adherents to the Nuclear Suppliers Group (NSG) Guidelines met for the first time in more than 13 years in The Hague in April 1991 it began a new and dynamic process for coordinating the full range of nuclear supplier issues. In less than four years the NSG has expanded its membership to 31 countries and has implemented major changes to its Guidelines and commodity control lists. Enhancements to the Regime agreed to by the Group since its reinvigoration include the adoption of controls on nuclear-related-dual-use equipment, materials and technology; the requirements for a recipient country to have an agreement with the International Atomic Energy Agency calling for safeguards on its entire nuclear program, both now and in the future; a major expansion of the Trigger List (the list of commodities which ''trigger'' safeguards as a condition of supply) to clarify and add detail to the controlled commodities; comparable controls on technologies associated with Trigger List items; and ''fixes'' to the Guidelines to control retransfers and exports to countries with suspect nonproliferation credentials. This paper provides a comprehensive overview of the NSG and discusses in detail the past, present and future work of the Group

    Full Text Available Effective supplier-buyer relationship management should not be seen only in terms of cost and financial measures, as outlined by Transaction cost economics, but also in terms of other (“softer” relational benefits, like e.g. more comprehensive information sharing, higher levels of trust, better cooperation and increased relationship flexibility. This second view is grounded in both Relationship marketing and Resource-advantage theory. Surprisingly, only a few research papers on supplier-buyer relationships address both of these perspectives equally, as well as in terms of long-term competitiveness (vis-avis a traditional short-term performance. The purpose of this paper is to analyze business relationship determinants of supplier-buyer relationship competitiveness, where we study the impact of (1 relationship-based information exchange, (2 network spillover effects, (3 transaction-specific investments, (4 trust, (5 cooperation (joint actions and (6 flexibility on perceived (7 supplier-buyer relationship competitiveness. In this regard the main research question of our study is: Which relational and transactional dimensions determine supplier-buyer relationship competitiveness, as well as how strongly? To provide the answer this research question we employ an exploratory-type Partial Least Squares (PLS regression in conjunction with a novel perspective of network spillover effects, as a set of independent variables in our model. The data set consists of a sample of 130 international suppliers (approx. 30 % response rate connected to a transnational company (TNC headquartered in Slovenia, which operates in the steel construction solutions’ industry. Our results clearly identify a relational and a transactional set of determinants of supplier-buyer relationship competitiveness, with the former having a significantly higher impact on competitiveness than the latter.

This paper propose a comprehensive study on the supplier selection metrics for infrastructure building, weight the importance of each metrics assigned and to find the relationship between the metrics among initiators, decision makers, buyers and users. With the metrics hierarchy of criteria importance, a supplier selection process can be defined, repeated and audited with lesser complications or difficulties. This will help the field of procurement to improve as this research is able to develop and redefine policies and procedures that have been set in supplier selection. Developing this systematic process will enable optimization of supplier selection and thus increasing the value for every stakeholders as the process of selection is greatly simplified. With a new redefined policy and procedure, it does not only increase the company’s effectiveness and profit, but also make it available for the company to reach greater heights in the advancement of procurement in Malaysia.

  6. The responsibility of nuclear suppliers in the international market

    International Nuclear Information System (INIS)

    1978-01-01

    As a result of escalating oil prices, the developing countries are more and more turning to nuclear energy. As these countries become a more significant part of the international market, unique issues must be faced by the utility and country concerned and the nuclear supplier. A fundamental prerequisite of a successful supplier/customer relationship is a good relationship between their two governments. The supplier can fulfil an effective liaison function to ensure efficiency of communications in this area. In the preplanning phase the supplier can play a major role in supplying information relative to siting, unit size, system planning and plant economics. Once the nuclear choice is made, the pros and cons of purchasing plants on a turnkey versus non-turnkey basis must be weighed. The customer must balance his available resources and experience against his desires for acquisition of overall plant and systems knowledge. During the planning and procurement phase the subject of training, maintenance and service facilities can be an effective part of a comprehensive nuclear programme. In fact, local training and service centres could logically be the first step of a long-term localization effort. With respect to localization the supplier should be capable and experienced in developing this capability and willing to make a long-term commitment in this area. Through a clearer understanding of the responsibilities of the nuclear supplier and a clear delineation of his role, developing nations can more adequately assess the basis upon which to move forward on a nuclear programme.

    Carden, Robert; DelliFraine, Jami L

    2004-11-01

    The purpose of this study was to identify factors that predict overall hospital satisfaction with blood suppliers. The data for this study came from a 2001 satisfaction survey of hospital blood bank managers conducted by the National Blood Data Resource Center. A total of 1325 blood-utilizing hospitals were included in the final study database. The measurement of hospital satisfaction with its blood supplier encompasses the five composites of the SERVQUAL model. The five composites are 1) tangibles, 2) reliability, 3) responsiveness, 4) assurance, and 5) empathy. Linear regression was performed with overall hospital satisfaction as the dependent variable and the five composites of the SERVQUAL model and control variables as predictors of overall hospital satisfaction with blood suppliers. Significant predictors of hospital satisfaction with blood suppliers are satisfaction with medical and clinical support provided by the blood center, satisfaction with the routine delivery schedule, and price (service fee) of red cells. Prior studies have demonstrated the importance of customer satisfaction to organizations. As organizations, blood centers can benefit from improved satisfaction from their hospital customers. Blood center strategies that focus on improving these three predictors of overall hospital satisfaction with primary blood suppliers will be the most likely to improve and/or maintain hospital customer satisfaction with primary blood suppliers.

    2016-02-22

    In recent years, the expiration of patents for large drug classes has increased the importance of post-patent drug markets. However, previous research has focused solely on patent drug markets. In this study, the authors evaluate the influence of preferred supplier contracts, the German approach to tendering, in post-patent drug markets using a hierarchical market share attraction model. The authors find that preferred supplier contracts are a powerful strategic instrument for generic manufacturers in a highly competitive environment. They quantify the effects of signing a preferred supplier contract and show that brand-name manufacturers are vulnerable to tendering. Therefore, brand-name manufacturers should readjust their strategies and consider including preferred supplier contracts in their marketing mix. In addition, the authors employ a simulation to demonstrate that a first-mover advantage might be gained from signing a preferred supplier contract. Furthermore, their results can be used as a blueprint for decision makers in the pharmaceutical industry to assess the market share effects of different contracting strategies regarding preferred supplier contracts.

    Full Text Available The main purpose of this article is to demonstrate how supplier relationship management (SRM enables the capture and creation of intellectual capital, thereby attaining and sustaining a strategic competitive advantage and increasing supply chain profitability. In order to achieve this purpose, a large part of the article is devoted to exploring the relatively new and unknown field of SRM. It is shown that an organisation must possess a thorough understanding of good supplier characteristics and of the drivers, benefits and requirements for the successful implementation of SRM, in order to enable that organisation to leverage their supplier relationships to ensure the capture of supplier expertise, patents, experiences etc. (i.e. their intellectual capital. The article then explores how the integration of technology in SRM applications can improve the efficiency of supplier collaboration and intellectual capital capture and creation. It is then demonstrated how efficient and collaborative supplier relationships improve supply chain profitability and competitiveness. Lastly, the article explores the implementation pitfalls and trends of SRM that must be constantly considered and monitored by an organisation in order to continually capture and create intellectual capital and reap the full benefits of SRM. This exploration involved an examination of contemporary literature, theories and business cases and subsequently revealed that SRM is a vital discipline/philosophy that must be implemented by any organisation wishing to achieve greater supply chain efficiency and competitiveness. This competitiveness can only be achieved through the mutual unlocking, sharing and leveraging of intellectual capital.

  10. Using MACBETH method for supplier selection in manufacturing environment

    Full Text Available Supplier selection is always found to be a complex decision-making problem in manufacturing environment. The presence of several independent and conflicting evaluation criteria, either qualitative or quantitative, makes the supplier selection problem a candidate to be solved by multi-criteria decision-making (MCDM methods. Even several MCDM methods have already been proposed for solving the supplier selection problems, the need for an efficient method that can deal with qualitative judgments related to supplier selection still persists. In this paper, the applicability and usefulness of measuring attractiveness by a categorical-based evaluation technique (MACBETH is demonstrated to act as a decision support tool while solving two real time supplier selection problems having qualitative performance measures. The ability of MACBETH method to quantify the qualitative performance measures helps to provide a numerical judgment scale for ranking the alternative suppliers and selecting the best one. The results obtained from MACBETH method exactly corroborate with those derived by the past researchers employing different mathematical approaches.

    2018-04-01

    Supplier order allocation is an important supply chain decision for an enterprise. It is related to the supplier’s function as a raw material provider and other supporting materials that will be used in production process. Most of works on order allocation has been based on costs and other supply chain performance, but very limited of them taking risks into consideration. In this paper we address the problem of order allocation of a single commodity sourced from multiple suppliers considering supply risks in addition to the attempt of minimizing transportation costs. The supply chain risk was investigated and a procedure was proposed in the risk mitigation phase as a form of risk profile. The objective including risk profile in order allocation is to maximize the product flow from a risky supplier to a relatively less risky supplier. The proposed procedure is applied to a sugar company. The result suggests that order allocations should be maximized to suppliers that have a relatively low risk and minimized to suppliers that have a relatively larger risks.

    This final rule implements a number of regulatory provisions that are applicable to all providers and suppliers, including durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) suppliers. This final rule establishes appeals processes for all providers and suppliers whose enrollment, reenrollment or revalidation application for Medicare billing privileges is denied and whose Medicare billing privileges are revoked. It also establishes timeframes for deciding enrollment appeals by an Administrative Law Judge (ALJ) within the Department of Health and Human Services (DHHS) or the Departmental Appeals Board (DAB), or Board, within the DHHS; and processing timeframes for CMS' Medicare fee-for-service (FFS) contractors. In addition, this final rule allows Medicare FFS contractors to revoke Medicare billing privileges when a provider or supplier submits a claim or claims for services that could not have been furnished to a beneficiary. This final rule also specifies that a Medicare contractor may establish a Medicare enrollment bar for any provider or supplier whose billing privileges have been revoked. Lastly, the final rule requires that all providers and suppliers receive Medicare payments by electronic funds transfer (EFT) if the provider or supplier, is submitting an initial enrollment application to Medicare, changing their enrollment information, revalidating or re-enrolling in the Medicare program.

    Full Text Available The local automotive suppliers are facing a number of important challenges such asglobalisation, new requirement in market specifications and the competition brought about by theAsean Free Trade Area (AFTA agreements. In an effort to enhance the competitiveness of themanufacturing sector, the government has implemented the Second Industrial Master Plan, IMP2(1996-2005. The focus of the IMP2 is more on innovation and applications of new technologies, sothat industries can move up the value chain of their activities. Innovative capabilities achieved fromcompanies’ new product development activities have been recognized to be crucial for companies tosustain their competitiveness and organisational success. The importance of product development ismost obvious in the context of the discussion on the competitiveness of the Malaysian automotivesuppliers. The study will focus on the small medium enterprises (SMEs that make up more than 60 %of these automotive suppliers. The study is to determine the extensiveness of the suppliers’ productdevelopment activities by examining the involvement of the suppliers in customer’s productdevelopment activities. Consequently, the impact of this involvement to the competitiveness of thesuppliers is examined. The results were established based from a survey to parts and componentssuppliers of Proton, the Malaysian car national assembler.

    2004-03-01

    CO 2-laser photothermal radiometry (PTR) was demonstrated to be suitable for the non-destructive and non-contact characterization (both optical and thermal) of solid phase agricultural commodities (fresh vegetables, fruits) and confectionery products (candy). Proper interpretation of PTR signals enable one to calculate two parameters, i.e. the well known thermal effusivity e ( e= λρc p, where λ and ρcp are the thermal conductivity and the volume specific heat, respectively) and a newly introduced physical quantity termed 'initial heating coefficient' chi ( χ= β/( ρcp), β is the absorption coefficient). Obtained values for e are in a good agreement with data reported in the literature. PTR enables one to rapidly determine e via a single measurement. As opposed to this, the knowledge of two out of three thermophysical parameters (thermal diffusivity, thermal conductivity and volume specific heat) is a condition sine qua non for determining effusivity in the conventional manner.

    Full Text Available The “Jatropha for Galápagos” (JFG project in Ecuador aims to progressively replace diesel with jatropha oil in the generation of electricity in The Galápagos Islands. Thus, understanding and motivating the participation of jatropha suppliers is a priority for the sustainability of JFG. For this reason, the factors influencing their decision-making to participate in the project have been identified and analyzed using a binomial logit model. The results show that factors found to positively influence the likelihood of participation include, amongst others, the supplier’s experience within the project, their participation in local organizations, and the degree of satisfaction with the price of jatropha oil. In addition, children from producer families’ collaboration in the harvest of jatropha increases the overall likelihood of participation within the project. Similarly, the distance to the collection center positively influences the chances of participation. Conversely, those suppliers with higher wages and those who declared that jatropha harvest starts in April have a reduced likelihood of participating in the project. The findings obtained from this project can help decision-makers develop new measures to improve the sustainability of the project through initiatives to motivate the participation of jatropha suppliers in the program.

  2. Optimizing Supply Chain Collaboration Based on Agreement Buyer-Supplier Relationship with Network Design Problem

    Directory of Open Access Journals (Sweden)

    Wahyudi Sutopo

    2016-12-01

    Full Text Available In recent years, the rising competitive environment with shorter product life cycles and high customization forces industries to increase their flexibility, speed up their response, and enhance concurrent engineering designs. To integrate these prospects, supply chain collaboration becomes a pertinent strategy for industries to strengthen their competitiveness. The network design problem is used to implement supply chain collaboration. In the buying and selling process, sharing information between buyer and supplier are important to obtain a transaction decision. The optimimum supply chain profit can be identified by mathematical model of network design problem. The Mathematical Model takes into consideration the uncertainity in negotiation of supply chain, transportation problems, and locationallocation of products from supplier to buyer in the planning based on the time value of money. The results show that the model can be used to optimize the supply chain profit. The supplier gets a profit because income were received in the initial contract, while the buyer profit comes from lower pay.

  3. Heat/mass transfer on effusion plate with circular pin fins for impingement/effusion cooling system with initial crossflow

    Hong, Sung Kook; Rhee, Dong Ho; Cho, Hyung Hee

    2005-01-01

    Impingement/effusion cooling technique is used for combustor liner or turbine parts cooling in gas turbine engine. In the impingement/effusion cooling system, the crossflow generated in the cooling channel induces an adverse effect on the cooling performance, which consequently affects the durability of the cooling system. In the present study, to reduce the adverse effect of the crossflow and improve the cooling performance, circular pin fins are installed in impingement/effusion cooling system and the heat transfer characteristics are investigated. The pin fins are installed between two perforated plates and the crossflow passes between these two plates. A blowing ratio is changed from 0.5 to 1.5 for the fixed jet Reynolds number of 10,000 and five circular pin fin arrangements are considered in this study. The local heat/mass transfer coefficients on the effusion plate are measured using a naphthalene sublimation method. The results show that local distributions of heat/mass transfer coefficient are changed due to the installation of pin fins. Due to the generation of vortex and wake by the pin fin, locally low heat/mass transfer regions are reduced. Moreover, the pin fin prevents the wall jet from being swept away, resulting in the increase of heat/mass transfer. When the pin fin is installed in front of the impinging jet, the blockage effect on the crossflow enhances the heat/mass transfer. However, the pin fin installed just behind the impinging jet blocks up the wall jet, decreasing the heat/mass transfer. As the blowing ratio increases, the pin fins lead to the higher Sh value compared to the case without pin fins, inducing 16%∼22% enhancement of overall Sh value at high blowing ratio of M=1.5

  4. A model of the supplier involvement in the product innovation

    Directory of Open Access Journals (Sweden)

    Kumar Manoj

    2017-01-01

    Full Text Available In this paper we examine the product innovation in a supply chain by a supplier and derive a model for a supplier’s product innovation policy. The product innovation of a supplier can contribute to the long-term competitiveness for the supply chain, and as it is for many supply chains a major factor, it should be considered in the development of strategies for a supplier. Here, we evaluate the effectiveness of supplier product innovation as a strategic tool to enhance the competitiveness and viability of supply chain. This paper explores the dynamic research performance of a supplier with endogenous time preference under a given arrangement of product innovation. We find that the optimal effort level and the achieved product innovation obey a saddle point path, or show tremendous fluctuations even without introducing the stochastic nature of product innovative activity. We also find that the fluctuation frequency is largely dependent both on the supplier’s characteristics such as supplier’s product innovative ability and on the nature of product innovation process per se. Short-run analyses are also made on the effect of supply chain cooperation in the product innovation process.

    This paper studies the Swedish component suppliers in the wind power industry. This group has not received much attention so far, and today very little is known. This study addresses the fact that the Swedish component suppliers have not been able to penetrate the wind power market despite the Swedish industry's strength in mechanical and electrical engineering. The aims of this paper were to gather information regarding the existing production and to identify factors that affect the Swedish component suppliers' scope to penetrate the wind turbine market. To date, although Sweden has spent considerable amounts of money on projects involving wind turbines, there is no series production of large wind turbines in Sweden. The historical development of the wind turbine industry suggests this alone would have inhibited the development of component production in Sweden. Yet, the country's proximity and good access to large wind turbine producing countries should be an advantage. Various factors and issues are identified and discussed in this paper that are relevant for the Swedish component suppliers' scope to penetrate the wind turbine market. These include market and product development, buyer-supplier relationships, export and sourcing behaviors, and time of market entry. This is a first step towards increasing the knowledge of Swedish component production and it is recognized that more studies are required. Various areas where relevant knowledge is largely missing or scarce are identified and discussed as well, and should serve as relevant starting points for continued research

    1986-01-01

    The suppliers of its goods and services are a most important resource of the utility industry. The unique and mutually beneficial technical relationship between utilities and their suppliers has been and continues to be a major contributor to the power industry's viability, vitality and growth, and thus to America's standard of living. The commercial and legal aspects of this relationship have been changing. This paper addresses the principles of: reasonably allocating and responsibility and accountability for ''the products'' provided to utilities including nuclear utilities; equitable risk-sharing as a prime requirement of utility procurement decision making; and the present and future relationship of the unique supplier/utility partnership as influenced and shaped by these requirements

    2006-01-01

    With energy demand rising and the increasing recognition of the role of nuclear power as part of the energy mix, opportunities and challenges face the nuclear industry. The ability of nuclear industries to respond to utility requirements in terms of costs, schedule and quality will be determined by entire supplier base. The author speaks to the challenge of the entire infrastructure of suppliers to respond to these opportunities and challenges. Key issues are resource planning, procurement, risk management, supplier collaborations (such as teaming and partnerships); standardization of practices to minimize costs and time; and not least of which, the training, development and recruitment of labour. The author shares his perspective on the role of the supply chain to ensure it has the right resources to provide safe, cost-effective and reliable nuclear deliverables

  13. A Hybrid Multiple Criteria Decision Making Model for Supplier Selection

    2013-01-01

    Full Text Available The sustainable supplier selection would be the vital part in the management of a sustainable supply chain. In this study, a hybrid multiple criteria decision making (MCDM model is applied to select optimal supplier. The fuzzy Delphi method, which can lead to better criteria selection, is used to modify criteria. Considering the interdependence among the selection criteria, analytic network process (ANP is then used to obtain their weights. To avoid calculation and additional pairwise comparisons of ANP, a technique for order preference by similarity to ideal solution (TOPSIS is used to rank the alternatives. The use of a combination of the fuzzy Delphi method, ANP, and TOPSIS, proposing an MCDM model for supplier selection, and applying these to a real case are the unique features of this study.

    It is essential for the safe and stable operations of Nuclear Power Plants that various resources in the supply chain are effectively managed. Supplier is a significant resource of nuclear entities serving as an extension of the operation process. Scientific and radiation evaluation of the performance of suppliers is of vital importance to an effective and high quality supply chain. This paper establishes an advance and practical supplier evaluation system that is applicable for the operational nuclear power plants, based on the analysis of the current operation status of Daya Bay Nuclear Power Station against its targeted objectives, the acquisition of relevant practices home and abroad and the benchmarking with advanced peers, in order to enhance the core competence of nuclear power plant.

  15. Weekly changes of power supplier - consequences for the network owner

    International Nuclear Information System (INIS)

    Graabak, Ingeborg

    1997-01-01

    In Norway, it is expected that owners of electric distribution networks will be required to make it possible for the customers to change supplier each week. This report examines what consequences such a requirement will have for the network owners. An inquiry among nine network owners shows that at present changing supplier implies a great deal of manual work on the part of the network owner since many do not have computer based tools adapted to handle the situation. If the number of weekly changes of suppliers does not increase beyond a few percent of the network owner's total number of customers over 1 to 3 years, the network owner can cope with the situation. However, if for some reason the increase becomes larger, many network owners will have great problems because they lack the necessary computer tools. 1 table

  16. The effects of magmatic redistribution of heat producing elements on the lunar mantle evolution inferred from numerical models that start from various initial states

    Science.gov (United States)

    Ogawa, Masaki

    2018-02-01

    To discuss how redistribution of heat producing elements (HPEs) by magmatism affects the lunar mantle evolution depending on the initial condition, I present two-dimensional numerical models of magmatism in convecting mantle internally heated by incompatible HPEs. Mantle convection occurs beneath a stagnant lithosphere that inhibits recycling of the HPE-enriched crustal materials to the mantle. Magmatism is modeled by a permeable flow of magma generated by decompression melting through matrix. Migrating magma transports heat, mass, and HPEs. When the deep mantle is initially hot with the temperature TD around 1800 K at its base, magmatism starts from the beginning of the calculated history to extract HPEs from the mantle. The mantle is monotonously cooled, and magmatism ceases within 2 Gyr, accordingly. When the deep mantle is initially colder with TD around 1100 K, HPEs stay in the deep mantle for a longer time to let the planet be first heated up and then cooled only slightly. If, in addition, there is an HPE-enriched domain in the shallow mantle at the beginning of the calculation, magma continues ascending to the surface through the domain for more than 3 Gyr. The low TD models fit in with the thermal and magmatic history of the Moon inferred from spacecraft observations, although it is not clear if the models are consistent with the current understanding of the origin of the Moon and its magnetic field. Redistribution of HPEs by magmatism is a crucial factor that must be taken into account in future studies of the evolution of the Moon.

  17. Nuclear liability and research reactor fuel. A plant supplier's view

    International Nuclear Information System (INIS)

    Roegler, H.-J.; Hetzmann, A.

    2000-01-01

    Contracts on Research Reactors are normally entered into by the owner and - very often - later user and the supplier of such plants. They are not concluded by the fuel supplier, except fuel supplier and plant supplier are identical. Thus, the fuel supplier mostly has no direct influence into the contract negotiations and the clauses which are eventually agreed upon between the parties. So has any other subcontractor for any other system or component. Any such subsupplier can and will negotiate a subsidiary supply contract (subcontract) with the supplier of the plant. The supplier drafts the related clauses so as to pass on to the subsupplier as many risks out of his contracts as possible. The subsupplier, on the other hand, tries to protect himself, tries to limit the risks he takes over, e.g. to the worth of his subcontract maximum. A critical issue in such negotiations is those concerning the risks the supplier had to accept and the subsupplier, although he may be responsible later for the risk changing to reality; i.e. the occurrence of a loss, cannot be hold liable for in full because the subcontract limits his liability, e.g. to the subcontract value or a certain delay penalty. A typical example for this conflict are delays of the entire project caused by one subsupplier. A very specific case in this context is the so-called nuclear liability. Nuclear liability means being hold responsible for the consequences or damages originating from a nuclear event in the plant. Those consequences or damages may be suffered by third parties, which are neither the owner/operator nor the supplier and result in a liability to such party (third party liability). Several of the aspects below may be related to the nuclear liability issue: The supplier often has its registered office not in the country where the plant is; The supplier may have far bigger assets than the owner/operator. The legal system of the supplier's country may be more favourable for enforcing claims of

    The author argues that international markets and multinational suppliers provide large benefits to utilities. It represents a long term commitment to the nuclear business that these companies will be able to supply nuclear technology on the long haul. The technology that is available around the world becomes available to everyone through the international markets and multinational suppliers. The increased experience base is seen as valuable in that errors that have been made or have not been made yet can be avoided through the transfer or experience. The security of supply is discussed as important to any utility that is operating a reactor

    Radionuclides in nuclear medicine can be used for diagnosis and therapy. The {sup 99m}Tc, son of {sup 99}Mo, is most often used in nuclear medicine as tracer element because of its favorable nuclear properties, accounting for about 80% of all diagnostic procedures in vivo. Aiming to resolve the dependency of Brazil with respect to the supply of {sup 99}Mo was created the Brazilian Multipurpose Reactor project (BMR), started in 2008, having as main objective to produce about 1000 Ci/week of {sup 99}Mo. This study is part of the project to obtain {sup 9}'9Mo by alkaline dissolution of UAl{sub x}-Al targets. The initial reaction temperature is an important parameter, since it has great influence on the value of the maximum temperature and dissolution time. According to literature, for security reasons the dissolution process must have its temperature controlled so that the maximum temperature has to be around 90 deg C. The behavior of the temperature during dissolution using three different methods of heating in order to minimize the fluctuation of temperature during dissolution, keeping its maximum value at around 90 deg C was studied. The three methods of heating chosen were: a) initial temperature of 85 deg C with continuous heating, b) heating water bath until it reaches the initial temperature (70 to 95 deg C), turning off after that, and c) external heating until it reached the starting temperature (60-95 deg C). The alkaline solution used was 3 mol.L{sup -1} NaOH{sub 3} and 2 mol.L{sup -1} NaNO{sub 3}. In the first study it was observed that after 1 minute of dissolution the solution temperature reached 100 deg C on average, up to a maximum of 109 deg C, ending with values around 95 deg C. In the second study after 3 minutes of dissolution the maximum temperature was 106 deg C and the minimum 100 deg C. In the third study the temperature rise during dissolution increased with increasing initial temperature which practically remains constant until the end

    Two-dimensional arrays of circular air jets impinging on a heat transfer surface parallel to the jet orifice plate are considered. The jet flow, after impingement, is constrained to exit in a single direction along the channel formed by the jet orifice plate and the heat transfer surface. The configurations considered are intended to model those of interest in current and contemplated gas turbine airfoil midchord cooling applications. The effects of an initial crossflow which approaches the array through an upstream extension of the channel are considered. Flow distributions as well as heat transfer coefficients and adiabatic wall temperatures resolved to one streamwise hole spacing were measured as a function of the initial crossflow rate and temperature relative to the jet flow rate and temperature. Both Nusselt number profiles and dimensionless adiabatic wall temperature (effectiveness) profiles are presented and discussed. Special test results which show a significant reduction of jet orifice discharge coefficients owing to the effect of a confined crossflow are also presented, along with a flow distribution model which incorporates those effects. A nonuniform array flow distribution model is developed and validated.

    The number of small heating plants using biomass is growing. According to TREND's information, Hrinovska energeticka, is the only one that controls the whole supplier chain in cooperation with its parent company in Bratislava. Starting with the collection and processing of wood chips by burning, heat production and heat distribution to the end user. This gives the company better control over costs and consequently its own prices. Last year, the engineering company, Hrinovske storjarne, decided to focus only on its core business and sold its heating plant, Hrinovske tepelne hospodarstvo, to Intech Slovakia and changed the company name to Hrinovska energeticka. Local companies and inhabitants were concerned that the new owner would increase prices. But the company publicly declared and kept promises that the heat price for households would remain at 500 Slovak crowns/gigajoule (13.33 EUR/gigajoule ), one of the lowest prices in Slovakia. This year the prices increased slightly to 570 Slovak crowns (15.2 EUR). 'We needed - even at the cost of lower profit - to satisfy our customers so that we would not lose them. We used this time for transition to biomass. This will allow us to freeze our prices in the coming years,' explained the statutory representative of the company, Ivan Dudak. (authors)

    Full Text Available In the market economy, competition is typically due to the difficulty in selecting the most suitable supplier, one that is capable to help a business to develop a profit to the highest value threshold and capable to meet sustainable development features. In addition, this research discusses a wide range of consequences from choosing an effective supplier, including reducing production cost, improving product quality, delivering the product on time, and responding flexibly to customer requirements. Therefore, the activities noted above are able to increase an enterprise’s competitiveness. It can be seen that selecting a supplier is complex in that decision-makers must have an understanding of the qualitative and quantitative features for assessing the symmetrical impact of the criteria to reach the most accurate result. In this research, the multi-criteria group decision-making (MCGDM approach was proposed to solve supplier selection problems. The authors collected data from 25 potential suppliers, and the four main criteria within contain 15 sub-criteria to define the most effective supplier, which has viewed factors, including financial efficiency guarantee, quality of materials, ability to deliver on time, and the conditioned response to the environment to improve the efficiency of the industry supply chain. Initially, fuzzy analytic network process (ANP is used to evaluate and rank these criteria, which are able to be utilized to clarify important criteria that directly affect the profitability of the business. Subsequently, data envelopment analysis (DEA models, including the Charnes Cooper Rhodes model (CCR model, Banker Charnes Cooper model (BCC model, and slacks-based measure model (SBM model, were proposed to rank suppliers. The result of the model has proposed 7/25 suppliers, which have a condition response to the enterprises’ supply requirements.

    Over the years, avionics systems have increased in complexity to the point where 1st tier suppliers to an aircraft OEM find it financially beneficial to outsource designs of subsystems to 2nd tier and at times to 3rd tier suppliers. Combined with challenging schedule and budgetary pressures, the environment in which safety-critical systems are being developed introduces new hurdles for regulatory agencies and industry. This new environment of both complex systems and tiered development has raised concerns in the ability of the designers to ensure safety considerations are fully addressed throughout the tier levels. This has also raised questions about the sufficiency of current regulatory guidance to ensure: proper flow down of safety awareness, avionics application understanding at the lower tiers, OEM and 1st tier oversight practices, and capabilities of lower tier suppliers. Therefore, NASA established a research project to address Regulatory Compliance in a Multi-tier Supplier Network. This research was divided into three major study efforts: 1. Describe Modern Multi-tier Avionics Development 2. Identify Current Issues in Achieving Safety and Regulatory Compliance 3. Short-term/Long-term Recommendations Toward Higher Assurance Confidence This report presents our findings of the risks, weaknesses, and our recommendations. It also includes a collection of industry-identified risks, an assessment of guideline weaknesses related to multi-tier development of complex avionics systems, and a postulation of potential modifications to guidelines to close the identified risks and weaknesses.

    Full Text Available The paper focuses on the issue of choice of suppliers in the market environment. It discusses expert systems as modern methods of its computer support. The issue of supplier choice is presented and viewpoints for the formulation of the decision-making task introduced. The piece of writing furthermore pinpoints the expert character of the solution of this task, making use of the knowledge of experienced professionals. It introduces the principles of fuzzy oriented expert systems as a suitable solution of the task at hand. Language models of the expert systems formalise the high quality mental models of an experienced expert. The global decision-making task is split into partial tasks; the expert modules for their formalisation are integrated into the hierarchic structure. The paper presents the structures of language models and the implementation of the structure of expert systems in the MATLAB-Simulink program environment. Special attention is paid to the issue of supplier flexibility. The efficiency of the decision-making system is proven by the solution of a simulation exercise which represents the classification of two current and two newly contemplated suppliers with various characteristics. The results are analysed and commented on.

    Full Text Available The determination of the optimal purchasing strategy in enterprise that is a part of global supply chain could be performed in two steps. In step one, a classification of potential suppliers is performed in order to determine the optimal portfolio of suppliers. This is delivered by using the fuzzy multicriteria proposed ABC classification method. Uncertainties in relative importance of criteria and their values are described by linguistic expressions. Modelling of linguistic expressions is based on the fuzzy sets theory. In the second step, ranking of optimal portfolio of suppliers is performed by using the modified ELECTRE method. The obtained results represent valuable input for determining the long time purchasing strategy and building partnership with the best suppliers. The developed two-step model is verified on real life data. The obtained results indicate good compliance with the opinions management in this type of industry. It is worth to mention that the proposed model can be easily extended and adopted to the analysis of other issues of management which could be applicable in different research areas.

    The industrial production route of Grain Oriented Electrical Steels (GOES) is complex and fine-tuned for each grade. Its metallurgical process requires in all cases the abnormal grain growth (AGG) of the Goss orientation during the final high temperature annealing (HTA). The exact mechanism of AGG is not yet fully understood, but is controlled by the different inhibition systems, namely MnS, AlN and CuxS, their size and distribution, and the initial primary recrystallized grain size. Therefore, among other parameters, the initial heating stage during the HTA is crucial for the proper development of primary and secondary recrystallized microstructures. Cold rolled 0.3 mm Cu-bearing Grain Oriented Electrical Steel has been submitted to interrupted annealing experiments in a lab tubular furnace. Two different annealing cycles were applied:• Constant heating at 30°C/h up to 1000°C. Two step cycle with initial heating at 100°C/h up to 600°C, followed by 18 h soaking at 600°C and then heating at 30°C/h up to 1050°C. The materials are analyzed in terms of their magnetic properties, grain size, texture and precipitates. The characteristic magnetic properties are analyzed for the different extraction temperatures and Cycles. As the annealing was progressing, the coercivity values (Hc 1.7T [A/m]) decreased, showing two abrupt drops, which can be associated to the on-set of primary and secondary recrystallization. The primary recrystallized grain sizes and recrystallized fractions are fitted to a model using a non-isothermal approach. This analysis shows that, although the resulting grain sizes were similar, the kinetics for the two step annealing were faster due to the lower recovery. The on-set of secondary recrystallization was also shifted to higher temperatures in the case of the continuous heating cycle, which might end in different final grain sizes and final magnetic properties. In both samples, nearly all the observed precipitates are Al-Si-Mn nitrides

As the annealing was progressing, the coercivity values (Hc 1.7T [A/m] decreased, showing two abrupt drops, which can be associated to the on-set of primary and secondary recrystallization. The primary recrystallized grain sizes and recrystallized fractions are fitted to a model using a non-isothermal approach. This analysis shows that, although the resulting grain sizes were similar, the kinetics for the two step annealing were faster due to the lower recovery. The on-set of secondary recrystallization was also shifted to higher temperatures in the case of the continuous heating cycle, which might end in different final grain sizes and final magnetic properties. In both samples, nearly all the observed precipitates are Al

    An investigation was carried out on the effect of different sterilization time on the trace metals concentration of palm oil whole extract. Palm fruits were collected, cleaned and sterilized for 0, 20, 40 and 60 minutes. The kernels were then stripped from the sterilized fruits to get the pulp and later the pulp was pressed using small scale expeller. The resulting puree was centrifuge at 4000 rpm for 20 minutes. The palm oil whole extract were then collected and trace metals analysis was conducted using Inductively Couple Plasma-Mass Spectrometry (ICP-MS). The result showed that the highest yield was obtained at 40 minutes of sterilization with 19.9 {+-} 0.21 % (w/w). There was no significant different (p < 0.5) in total trace metals content between the degrees of the heat treatment. Na+ was found as the highest trace metals content in the extract with mean concentration ranging from 1.05 {+-} 0.03 ppm to 2.36 {+-} 0.01 ppm. 40 minutes of heating time was predicted to have good oil quality due to higher content in trace metals that inhibit the lipase enzyme activity.

    Full Text Available On existing conditions on global market (almost identical quality, almost identical purchasing values companies have to definite the total rating of importance of evaluative criteria. In post-crisis period the problem of suppliers’ evaluation is one of the biggest, because companies had to use all resources and all possibilities to develop their own business. Many authors wrote about collaborative planning and warehousing as one of possibilities to optimization work inside supply chain. For this paper define small and medium-sized enterprises (SME as enterprises with the size of maximum 250 em­ployers. In literature was read we couldn’t find information about own system of suppliers evaluation for small and medium-sized enterprises. SME can have some different types of business and in this case need the universal system of eva­lua­tion. The research of this paper is oriented on small and medium-sized enterprises with different types of business. The new theoretical universal method of calculation for evaluation existing suppliers for small and medium-sized enterprises will present in this paper. This theoretical method is based on average values. This method includes traditional evaluative criteria (quality, delivery time and other (mobility of supplier, possibilities of new level of partnership. This method of evaluation can not be used for continual manufacture. New method can improve the total evaluation of supplier in small and medium-sized enterprises.

    Full Text Available Background: Supplier performance management continues to be a significant concern for small & medium enterprises (SME. How can small & medium enterprises better position themselves to check and sustain actual supplier performance improvement? A key framework is the establishment of a value-added supplier performance audit program that places significant emphasis on supplier performance controls. A value-added supplier audit program can help SME mitigate business and regulatory risk while reducing the cost of poor quality (COPQ. Thus a good supplier performance audit program is the cornerstone of supplier performance management integrity. Methods: By acknowledging and addressing the challenges to an effective supplier Performance Audit program, this paper proposes an objective framework of supplier performance audit program, built on a strong, yet versatile statistical methodology - Analysis of variance (ANOVA. This performance audit framework considers process definition, standardization, review of the contemporary literature on ANOVA & its practical application in supplier performance scorecard of one of the reputed Sports Goods Industry in India. Results and conclusions: The advantages of this framework are that: it simultaneously considers multiple supplier performance in multiple time frames and effectively identifies the differences across the suppliers in terms of their performance. Through this framework the organization will be able to increase the odds of performing a predictable and successful implementation of a value-added supplier performance audit.

    Full Text Available The Firebrick Resistance-Heated Energy Storage (FIRES concept developed by the Massachusetts Institute of Technology aims to enhance profitability of the nuclear power industry in the next decades. Studies carried out at Massachusetts Institute of Technology already provide estimates of the potential revenue from FIRES system when it is applied to industrial heat supply, the likely first application. Here, we investigate the possibility of operating a power plant (PP with a fluoride-salt-cooled high-temperature reactor and a closed Brayton cycle. This variant offers features such as enhanced nuclear safety as well as flexibility in design of the PP but also radically changes the way of operating the PP. This exploratory study provides estimates of the revenue generated by FIRES in addition to the nominal revenue of the stand-alone fluoride-salt-cooled high-temperature reactor, which are useful for defining an initial design. The electricity price data is based on the day-ahead markets of Germany/Austria and the United States (Iowa. The proposed method derives from the equation of revenue introduced in this study and involves simple computations using MatLab to compute the estimates. Results show variable economic potential depending on the host grid but stress a high profitability in both regions.

  16. Dryout-type critical heat flux in vertical upward annular flow: effects of entrainment rate, initial entrained fraction and diameter

    Science.gov (United States)

    Wu, Zan; Wadekar, Vishwas; Wang, Chenglong; Sunden, Bengt

    2018-01-01

    This study aims to reveal the effects of liquid entrainment, initial entrained fraction and tube diameter on liquid film dryout in vertical upward annular flow for flow boiling. Entrainment and deposition rates of droplets were included in mass conservation equations to estimate the local liquid film mass flux in annular flow, and the critical vapor quality at dryout conditions. Different entrainment rate correlations were evaluated using flow boiling data of water and organic liquids including n-pentane, iso-octane and R134a. Effect of the initial entrained fraction (IEF) at the churn-to-annular flow transition was also investigated. A transitional Boiling number was proposed to separate the IEF-sensitive region at high Boiling numbers and the IEF-insensitive region at low Boiling numbers. Besides, the diameter effect on dryout vapor quality was studied. The dryout vapor quality increases with decreasing tube diameter. It needs to be pointed out that the dryout characteristics of submillimeter channels might be different because of different mechanisms of dryout, i.e., drying of liquid film underneath long vapor slugs and flow boiling instabilities.

    2014-12-01

    Evaluating supplier quality performance is vital in ensuring continuous supply chain improvement, reducing the operational costs and risks towards meeting customer's expectation. This paper aims to illustrate an application of Fuzzy Analytical Hierarchy Process to prioritize the evaluation criteria in a context of automotive manufacturing in Malaysia. Five main criteria were identified which were quality, cost, delivery, customer serviceand technology support. These criteria had been arranged into hierarchical structure and evaluated by an expert. The relative importance of each criteria was determined by using linguistic variables which were represented as triangular fuzzy numbers. The Center of Gravity defuzzification method was used to convert the fuzzy evaluations into their corresponding crisps values. Such fuzzy evaluation can be used as a systematic tool to overcome the uncertainty evaluation of suppliers' performance which usually associated with human being subjective judgments.

    International Nuclear Information System (INIS)

    Schmidt, D.G.

    1993-01-01

    The fundamental decision to automate a particular radiochemical synthesis for in house use depends primarily on the demand for the compound and the total number of studies to be carried out with that compound. For a commercial supplier of automated chemistry systems, much more goes in to the decision to design, develop and produce a particular automated chemistry system. There is a dramatic difference in design effort between an industrial environment and an academic environment. An in house system must be built only once and needs only to incrementally simplify the synthesis process. A commercial product must: have reasonable manufacturing costs; be easy to use; be aesthetically pleasing; be easy to install and service; be functionally integral with other equipment sold by the manufacturer; be marketable within the regulatory environment; address radiation safety issues. This paper discusses issues that guide commercial suppliers in the formation of their product lines

    This document provides guidelines for planning and conducting performance-based audits of suppliers of items used in nuclear power plants. A common purpose of audits is to provide a basis for confidence in the supplier's controls to ensure that products received will perform their intended functions satisfactorily. Performance-based audits offer means of raising the level of confidence. This confidence comes from evaluation of important features of the product and the processes and activities that produce it. This document does not add requirements to those in existing codes, standards, or regulations. The guidance herein is intended to complement the information in existing industry standards and practices. Performance-based audits are one element of an effective procurement program. A companion EPRI/NCIG document, EPRI NP-6629, Guidelines for the Procurement and Receipt of Items for Nuclear Power Plants (NCIG-15), provides guidance for other elements of an effective procurement program

In principle, in almost all nuclear power countries, liability is channelled to the operator; suppliers and service providers are exempted from liability. However, there are conceivable cases in which this principle does not apply. This can occur, for example, if a major accident is assumed to have an impact on neighbouring countries of the country of destination; here, depending on the applicable law, the German supplier or service provider could be ordered to pay for damages. The risk of liability remaining in this way can be reduced if necessary by means of an exemption clause in the supply contract. The regulation of the operator's recourse to the contractor, insofar as the latter is responsible for the accident, and the - controversial -question of to what extent damage to the plant itself gives rise to claims for damages by the operator against the contractor are also discussed.

    CERN Multimedia

    Jenni, P

    On 12 February the Netherlands firm Schelde Exotech was awarded the ATLAS Supplier Award for the construction of the two vacuum vessels for the ATLAS End- Cap Toroid (ECT) magnets. ATLAS Supplier Award ceremonies have now become something of a tradition. For the third consecutive year, ATLAS has given best supplier awards for the most exceptional contributors to the construction of the detector. The Netherlands firm Schelde Exotech has just received the award for the construction of the two vacuum vessels for the ECTs. With a diameter of 11 metres and a volume of 550 cubic metres, the ECT vacuum vessels are obviously impressive in scale. They consist of large aluminium plates and a stainless steel central bore tube. In order to obtain the required undulations, the firm had to develop a special assembly and welding technique. Despite the chambers' imposing size, a very high degree of precision has been achieved in their geometry. Moreover, the chambers, which were delivered in July 2002 to CERN, were built i...

    Full Text Available Small grocery stores are forced to look for ways to retain customers. One possibility is through collaboration with suppliers. Therefore, the aim of this research was to determine the forms of collaboration between small Czech grocery stores and suppliers and to specify the differences in this collaboration depending on store location and the possible affiliation of the store with a retail chain. To achieve this goal, quantitative research was carried out among 65 Czech retail stores using face-to-face interviews with predetermined questions. Collaboration was assessed on the basis of four criteria defined by the authors. It was found that the most frequently occurring element of collaboration was the provision of trade credit to retailers – less often, long-term contracts and synchronization of replenishment. The least used was information sharing. The research results show that the form of collaboration is significantly affected by customer value. Therefore, the level of collaboration can be improved by building horizontally interconnected retail chains. The paper enriches theoretical knowledge by specifying possible elements of collaboration between small retail stores and suppliers and mapping the frequency of their implementation.

    Several technical and logistical obstacles were encountered. These included high data costs; difficulty in accessing AT information from the public healthcare sector, the largest supplier of AT; and the high human resource demand of collecting and keeping up-to-date device-level information within a complex and fragmented supply sector that spans private, public and civil society entities. The challenges were dealt with by keeping the data burden low and eliminating product-level tracking. The App design was expanded to include disability services, contextually specific AT categories and make navigation more intuitive. Long-term sustainability strategies like generating funding through advertisements on the App or supplier usage fees must be explored. Outreach and sensitisation programmes about both the App and AT in general must be intensified. The project team must continually strengthen partnerships with private and public stakeholders to ensure ongoing project engagement. The lessons learnt might be of value to others who wish to embark on initiatives in AT and/or implement Apps in health or disability in southern Africa and in low-resourced settings around the world.

    A market for energy services is emerging. Energy suppliers and building services contractors have the same customers but have traditionally operated in different markets. The boundary between the energy and building services markets is blurred. Substantial degrees of freedom are being created for the customer in a free market. After the initial euphoria about this, there will be a realization that there are also risks, for example as a result of price fluctuations, uncertainty about supplier reliability, the effects of the rates system, complex regulation and political decision making. If people want to reduce these risks and through this make costs controllable, attention must be paid to the interdependence between aspects on the supply side, in the energy supply system and on the demand side [nl

  7. Joint Economic Lot Sizing Optimization in a Supplier-Buyer Inventory System When the Supplier Offers Decremental Temporary Discounts

    2012-02-01

    Full Text Available This research discusses mathematical models of joint economic lot size optimization in a supplier-buyer inventory system in a situation when the supplier offers decremental temporary discounts during a sale period. Here, the sale period consists of n phases and the phases of discounts offered descend as much as the number of phases. The highest discount will be given when orders are placed in the first phase while the lowest one will be given when they are placed in the last phase. In this situation, the supplier attempts to attract the buyer to place orders as early as possible during the sale period. The buyers will respon these offers by ordering a special quantity in one of the phase. In this paper, we propose such a forward buying model with discount-proportionally-distributed time phases. To examine the behaviour of the proposed model, we conducted numerical experiments. We assumed that there are three phases of discounts during the sale period. We then compared the total joint costs of special order placed in each phase for two scenarios. The first scenario is the case of independent situation – there is no coordination between the buyer and the supplie-, while the second scenario is the opposite one, the coordinated model. Our results showed the coordinated model outperform the independent model in terms of producing total joint costs. We finally conducted a sensitivity analyzis to examine the other behaviour of the proposed model. Keywords: supplier-buyer inventory system, forward buying model, decremental temporary discounts, joint economic lot sizing, optimization.

    Full Text Available Supplier selection is one of the most critical activities of purchasing management in supply chain. Supplier selection is a complex problem involving qualitative and quantitative multi-criteria. A trade-off between these tangible and intangible factors is essential in selecting the best supplier. The work incorporates AHP in choosing the best suppliers. The results suggest that AHP process makes it possible to introduce the optimum order quantities among the selected suppliers so that the Total Value of Purchasing (TVP becomes maximum. In this work, an AHP-based supplier selection model is formulated and then applied to a real case study for a steel manufacturing company in Malaysia. The use of the proposed model indicates that it can be applied to improve and assist decision making to resolve the supplier selection problem in choosing the optimal supplier combination. The work represents the systematic identification of the important criteria for supplier selection process. In addition, the results exhibit the application of development of a multi-criteria decision model for evaluation and selection of suppliers with proposed AHP model, which by scoring the performance of suppliers is able to reduce the time taken to select a vendor.

    Full Text Available Suppliers of goods present a very important cost object for trading companiessuch as retail. There is, however, no theoretical explanation as to how to calculate a contribution to profits generated from an individual supplier. This calculation is the subject of the paper. There is no calculation that shows how goods, provided from the supplier, create profit through gross margin and how the supplier`s behavior influences the costs (like delivery terms, costs of keeping specific goods fresh…. The final costs further decrease the profit generated by suppliers. As they have long found it illogical to calculate contribution to profit from suppliers in a production company, trading companies have long ignored it, as well. The Activity Based Costing (ABC, as the up-to-date system, still does not possess the cost hierarchy for suppliers as the cost object. The aim of the paper is to present a proposal for creating the cost hierarchy for suppliers in a trade company through creating a theoretical financial model as a method. The model also offers a theoretical explanation of how to calculate the contribution from a supplier or a group of suppliers. It is based on empirically evident activities in any supermarket or hypermarket, which makes it possible to create explanatory theoretical research.

    Full Text Available Malware suppliers use various modes to provide goods and services to customers. By mode, we mean “the way” the malware supplier chooses to function. These modes increase monetization opportunities and enable many security breaches worldwide. A theoretically sound framework that can be used to examine the various modes that malware suppliers use to produce and sell malware is needed. We apply a general model specified recently by Hagiu and Wright to study five modes that malware suppliers use to deliver goods and services to their customers. The framework presented in this article can be used to predict the mode in which a malware supplier will function; to study which types of malware suppliers, agents, and customers are attracted to each mode; to discover new modes; and to better understand the threat a malware supplier presents.

    Chicken slaughterhouse industry is one of the fastest growing industries that depends on the freshness of raw materials. The raw materials quality arrive at the company depends heavily on the suppliers. Fresh chicken and frozen chicken meat are the main raw materials for this industry. Problems occurred by the suppliers are catering the amount of raw material needs that are not appropriate and also delay during delivery process. This condition causes disruption of the production process in the company. Therefore, it is necessary to determine the best suppliers to supply the main raw materials of fresh and frozen chicken meat on the slaughterhouse chicken industry. This study analyze the supplier’s capability by using TOPSIS method. This method use to find out the best supplier. The TOPSIS method is performed using the principle that chosen alternative must have the shortest distance from the positive solution and furthest from the ideal solution of the geometric point by using the Euclidean distance to determine the relative proximity of the optimum solution alternative. TOPSIS method found the rank of best supplier’s order is supplier A followed by supplier D, supplier B, supplier C, supplier E, supplier F, and supplier G. Based on the rank order obtained from each company, it will assist the company in prioritizing the order to the supplier with the best rank. Total supply from All suppliers are 885,994 kg per month. Based on the results of research, the top five suppliers have been sufficient to meet the needs of the company.

    The development of a centralised and sustainable heat supply through the construction of heat grids offers consumers numerous advantages compared to a decentralised energy supply of residential and commercial properties. Where the migration to centralised heat supply relegates fossil fuels through the long-term incorporation of sustainable renewable energy sources, the projects make an important contribution towards meeting the government's climate protection goals. Heat generation and heat sales from renewable energy sources should be ensured in the long term. In the countryside, biogas plant operators are frequently the initiators of heat grid investments, or they take on the role of supplier for the provision of low-cost CHP heat from cogeneration units. In view of the limited remuneration period under the terms of the German Renewable Energy Act, the clock is ticking for the establishment of a centralised heat supply. This paper presents the advantages and disadvantages of a centralised, sustainable heat supply and additionally considers the flexibi/isation of biogas plants in view of the construction of the heat grid and the associated infrastructure. A focus is placed on the security of supply for customers after the discontinuation of remuneration under the German Renewable Energy Act and on how a competitive heat price from alternative energy sources can continue to be ensured.

  5. How Do Contractors Select Suppliers for Greener Construction Projects? The Case of Three Swedish Companies

    Directory of Open Access Journals (Sweden)

    Shahin Mokhlesian

    2014-06-01

    Full Text Available There are many studies of contractor selection based on clients and the selection of suppliers by contractors. However, supplier selection specifically related to green construction projects has been much less studied. Green construction differs from conventional construction because of differences in its underlying principles and use of environmentally-friendly materials and technologies. This paper studies how procurers in contractor companies in Sweden adopt green projects and how contractor perception of supplier mastery of green knowledge affects supplier selection. The investigation is based on a set of semi-structured interviews conducted among three large contractors in Sweden. A main finding is that the perceived differences between green and conventional projects do not change supplier selection dramatically. An implication is that “greener projects” is a more appropriate denotation than “green project”. Evidence shows that suppliers’ green knowledge is an important factor in supplier selection, as respondents rated suppliers’ knowledge of green projects as very important, and to fix his, there was a consensus among respondents about the need for close collaboration between contractors and suppliers. To ensure knowledge acquisition from suppliers and to increase their competitive advantage over rivals, contractors collaborate with their suppliers in a partnering setting. It is anticipated that the results of this study will be used to fill the gap in the literature on supplier selection in green projects and can also be used for construction firms contemplating getting involved in green projects.

    Full Text Available This study aims to establish a green supplier selection and guidance mechanism by integrating the features of an ANP (Analytic Network Process and an IPA (Importance–Performance Analysis to achieve sustainable management for green supply chains. Using an expert survey, this study developed green supplier selection criteria. It adopted an ANP, which allows for interdependencies and feedback between the various criteria, to select competitive green suppliers. Then, it used an IPA, which can analyze the criteria’s significance and performance levels, to provide green suppliers with direction for guidance and improvements. The green supplier selection and guidance mechanism featuring an ANP and IPA is thus established and validated through case studies. The research results showed the following: (1 the green supplier selection criteria comprise a total of 11 performance evaluation criteria from the three dimensions of operation, competence, and environmental consciousness; (2 as shown by the APN evaluation results, environmental benefits, environmental regulations, finance, technological competence, and delivery time are the top five among the overall green criteria of the company; the performance of the various suppliers is thus arranged in order, and the most competitive supplier is selected; (3 an IPA is used to analyze the criteria’s significance and supplier performance levels and to provide the suppliers with suggestions on priority improvements, including implementing the requirements in the environmental regulations, establishing comprehensive financial management procedures, improving corporate technological competence, and consolidating customer service; (4 it is suggested that an ANP and IPA should be integrated in the applications, which could simplify the green supplier selection and guidance mechanisms and increase the efficiency of supplier management, thus creating a three-win situation for the clients, the company, and the

    Supplies are always in great demand when it comes to industrial operations. The quality of raw material their price accompanied by sustainability and environmental effects are a major concern for industrial operators these days. Supply Chain Management is the subject which is focused on how the supply of different products is carried out. The motive is that each operation performed can be optimized and inherently the efficiency of the whole chain is integrated. In this paper we will be dealing with all the criteria that are required to be evaluated before selecting a supplier, in particular, focusing on Thermal Power Plant. The most suppliers of the thermal power plant are the coal suppliers. The quality of coal directly determines the efficiency of the whole plant. And when there are matters concerning coal environmental pollution plays a very crucial role. ANP method has been used here to select suppliers of thermal power sectors in Indian context. After applying ANP to prioritize the sustainable supplier selection criteria, it is found that for thermal power industries best suppliers are Nationalized/State owned suppliers then 2nd ranked suppliers are imported supplier. Private owned suppliers are ranked least. So private owned suppliers must be more concerned about their performance. Among these suppliers it is found that to compete in the global market privatized suppliers have to give more emphasize on most important criteria like sustainability, then fuel cost and quality. Still some sub-criteria like a clean program, environmental issues, quality, reliability, service rate, investment in high technology, green transportation channel, waste management etc needs for continuous improvement as per their priority.

    Full Text Available This paper investigates the effects of demand disruptions on production control and supplier selection in a three-echelon supply chain system. The customer demand is modeled as a jump-diffusion process in a continuous-time setting. A two-number production-inventory policy is implemented in the production control model for the manufacturer. The objective is to minimize the long-term average total cost consisting of backlog cost, holding cost, switching cost, and ordering cost. The simulated annealing method is applied to search the optimal critical switching values. Furthermore, an improved analytical hierarchy process (AHP is proposed to select the best supplier, based on quantitative factors such as the optimal long-term total cost obtained through the simulated annealing method under demand disruptions and qualitative factors such as quality and service. Numerical studies are conducted to demonstrate the effects of demand disruptions in the face of various risk scenarios. Managerial insights from simulation results are provided as well. Our approaches can be implemented as the “stress test” for companies in front of various supply chain disruption scenarios.

    Improving a company"s environmental and financial performance necessitates the evaluation of environmental impacts deriving from the production and cost effects of corporate actions. These effects have to be made transparent and concrete targets have to be developed. Such an evaluation has to be done on a regular basis but with limited expenses. To achieve this, different instruments of environmental controlling such as LCA and environmental performance indicators have to be combined with methods from cost accounting. Within the research project CARE (Computer Aided Resource Efficiency Accounting for Medium-Sized Enterprises), the method Resource Efficiency Accounting (REA) is used to give the participating companies new insights into hidden costs and environmental effects of their production and products. The method combines process based cost accounting with environmental impact assessment methodology and offers results that can be integrated into a company"s environmental controlling system and business processes like cost accounting, supplier assessment, etc. Much of the data necessary for the combined assessment can be available within a company"s IT system and therefore can be efficiently used for the assessment process. The project CARE puts a strong focus on the use of company data and information systems for the described assessment process and offers a methodological background for the evaluation and the structuring of such data. Besides the general approach of the project CARE the paper will present results from a case study in which the described approach is used for the evaluation of suppliers.

    Coordinating business operation with suppliers becomes increasingly important to survive and prosper under the dynamic business environment. A good partnership with suppliers not only increase efficiency, but also strengthen corporate competitiveness. Associated with such concern, this study aims to develop a practical approach of multi-criteria supplier evaluation using combined methods of Taguchi loss function (TLF), best-worst method (BWM) and VIse Kriterijumska Optimizacija kompromisno Resenje (VIKOR). A new framework of integrative approach adopting these methods is our main contribution for supplier evaluation in literature. In this integrated approach, a compromised supplier ranking list based on the loss score of suppliers is obtained using efficient steps of a pairwise comparison based decision making process. Implemetation to the case problem with real data from crumb rubber industry shows the usefulness of the proposed approach. Finally, a suitable managerial implication is presented.

    2016-01-01

    Within their own organizations, utilities have made significant improvements in human performance and safety culture, supported by a strong community of practice through INPO and WANO. In recent years, utilities have been making increasing use of suppliers for design, construction, inspection and maintenance services in support of their NPPs. Many of these suppliers do not have the benefit of being members of a community of practice when it comes to human performance and safety culture. To help the supplier community make improvements similar to what the utilities have achieved, INPO has recently expanded its Supplier Participant program to address the issue of human performance and safety culture in the supplier community. The intent of this paper will be to share the INPO’s perspectives and activities in helping suppliers of services and products to NPPs enhance their human performance and safety culture. (author)

    2014-01-01

    We introduce a wholesale pricing strategy for an incumbent supplier facing with a competitive counterpart. We propose a profit function which considers both the present loss and future loss from a wholesale price and then study the optimal wholesale prices for different objectives about this profit function for the incumbent supplier. First, we achieve an optimal wholesale price for the incumbent supplier to maximize his expected profit. Then, to reduce the risk originating from the fluctuation in the competitive supplier's wholesale price, we integrate the conditional value-at-risk (CVaR) measure in financial risk management into this study and derive an optimal wholesale price to maximize CVaR about profit for the incumbent supplier. Besides, the properties of the two optimal wholesale prices are discussed. Finally, some management insights are suggested for the incumbent supplier in a competitive setting.

    2018-01-01

    Full Text Available Supplier selection is one of the most important elements in supply chain management. This function involves evaluation of many factors such as, material costs, transportation costs, quality, delays, supplier capacity, storage capacity and others. Each of these factors varies with time, therefore, supplier identified for one period is not necessarily be same for the next period to supply the same product. So, mixed integer linear programming (MILP was developed to overcome the dynamic supplier selection problem (DSSP. In this paper, a mixed integer linear programming model is built to solve the lot-sizing problem with multiple suppliers, multiple periods, multiple products and quantity discounts. The buyer has to make a decision for some products which will be supplied by some suppliers for some periods cosidering by discount. To validate the MILP model with randomly generated data. The model is solved by Lingo 16.

    2014-06-01

    Full Text Available Supplier selection is an important concern of a firm’s competitiveness, more so in the context of the imperative of supply-chain management. In this paper, we use an approach to a multiobjective supplier selection problem in which the emphasis is on building supplier portfolios. The supplier evaluation and order allocation is based upon the criteria of expected unit price, expected score of quality and expected score of delivery. A fuzzy approach is proposed that relies on nonlinear S-shape membership functions to generate different efficient supplier portfolios. Numerical experiments conducted on a data set of a multinational company are provided to demonstrate the applicability and efficiency of the proposed approach to real-world applications of supplier selection

  19. Utility Expectations for Human Performance and Safety Culture in the Supplier Community

    2016-01-01

    Canadian NPPs, like many others around the world, make use of suppliers for the design and execution of major projects, and to support on-going inspection and maintenance activities. The work performed by suppliers today represents a significant portion of the work performed at utility NPPs, and, at times, can even exceed the work performed by utility staff. It is imperative for both the utility and the supplier work forces to work in collaboration to ensure that the probability of consequential errors impacting plant safety or contributing to broader enterprise risk is kept very low. An important element for keeping the risk low is for utilities to work with their suppliers to develop a high degree of confidence that the supplier workforce is performing to the same standards of human performance and safety culture as its own staff. This paper will provide a senior utility executive’s expectations and perspective on achieving excellence in supplier human performance and safety culture. (author)

    2015-11-10

    Pharmaceutical excipients have different functions within a drug formulation, consequently they can influence the manufacturability and/or performance of medicinal products. Therefore, critical to quality attributes should be kept constant. Sometimes it may be necessary to qualify a second supplier, but its product will not be completely equal to the first supplier product. To minimize risks of not detecting small non-similarities between suppliers and to detect lot-to-lot variability for each supplier, multivariate data analysis (MVA) can be used as a more powerful alternative to classical quality control that uses one-parameter-at-a-time monitoring. Such approach is capable of supporting the requirements of a new guideline by the European Parliament and Council (2015/C-95/02) demanding appropriate quality control strategies for excipients based on their criticality and supplier risks in ensuring quality, safety and function. This study compares calcium hydrogen phosphate from two suppliers. It can be assumed that both suppliers use different manufacturing processes. Therefore, possible chemical and physical differences were investigated by using Raman spectroscopy, laser diffraction and X-ray powder diffraction. Afterwards MVA was used to extract relevant information from each analytical technique. Both CaHPO4 could be discriminated by their supplier. The gained knowledge allowed to specify an enhanced strategy for second supplier qualification. Copyright © 2015 Elsevier B.V. All rights reserved.

    2008-08-01

    Full Text Available Several authors have been studying group decision making over the years, which indicates how relevant it is. This paper presents a multicriteria group decision model based on ELECTRE IV and VIP Analysis methods, to those cases where there is great divergence among the decision makers. This model includes two stages. In the first, the ELECTRE IV method is applied and a collective criteria ranking is obtained. In the second, using criteria ranking, VIP Analysis is applied and the alternatives are selected. To illustrate the model, a numerical application in the context of the selection of suppliers in project management is used. The suppliers that form part of the project team have a crucial role in project management. They are involved in a network of connected activities that can jeopardize the success of the project, if they are not undertaken in an appropriate way. The question tackled is how to select service suppliers for a project on behalf of an enterprise that assists the multiple objectives of the decision-makers.Vários autores têm estudado decisão em grupo nos últimos anos, o que indica a relevância do assunto.

    Henckes, A.

    2010-01-01

    With a road map of 84 (low scenario) to 198 (high scenario)* nuclear power plants to be build in the coming decade arise with intensity safety concerns. The challenge for governments and for nuclear companies as they increase construction is to manage a growing army of contractors and subcontractors worldwide and the quality of their production as well as their ability to deliver in time considering the speed-up and increasing pace of project development. Moreover by the last few years, the scope of needs for nuclear companies to set a QA/QC plan all along the supply chain has been increasingly enlarged with new stakes such as cost savings, social responsibilities and technical compliance. At last, with 'nuclear renaissance', the path to renew accreditation of existing suppliers facing international and domestic law/regulations combinations after a long period of low tide is now clear and wide. Nuclear operating companies and EPIC contractors now face a complex situation where on one side political pressure is hugely strong for a zero incident status to be considered as on the contrary the 'renaissance' will be suddenly stopped, on the other the status of 'industrial' maturity of the supply chain candidates is difficult to assess in a uniform and 'fair' way. Through this paper, the speaker will explain the full size supplier assessment strategy from paper to field which has been implemented in the Oil and Gas sector whose requirements of quality is high too. The speaker will present the key practices of this initiative from which the nuclear market can find more than a source of inspiration. (authors)

    1987-01-01

    In the past 10 yr, the international market for nuclear fuel cycle products and services, mainly yellowcake and separative work units (SWUs), has been characterized by shifting patterns in global demand and resource allocation. For suppliers as well as buyers, the analysis of the supply and demand pattern over the next 10 yr can be a useful exercise, especially if it highlights geopolitical realities and the influence of new technologies. This paper will attempt to answer two questions related to the marketing of natural uranium and enrichment services: (1) on a global basis (i.e., for the Western World), are uranium and enrichment capacities now on line sufficient to meet long-term demand. (2) On a regional basis (the US, Europe, and Far East), what is the short-to-medium term pattern of the supply-and-demand balance

    2011-04-01

    Full Text Available Managing multiple buyer-seller relationships in business-to-business networks demands an understanding of a firm’s competence to manage in an interconnected environment.  This paper reports on an attempt to measure network competence by using the NetCompTest scale in business-to-business markets in South Africa. Based on a pilot study refinement, the paper proposes an adjusted measurement scale and details the results of a second round of measurement conducted amongst 495 business-to-business managers in South Africa. The results established partial support for the use of the NetCompTest scale in a South African context, and analysis of variance indicated that some differences in the measurement based on firm and individual characteristics can be observed in the data. The paper assists in theory-building and provides managerial insights for managing buyer-supplier relationships in networks.

    2016-01-01

    Full Text Available In today’s competitive environment, supply chain need to be of high speed and flexibility, i.e., agile. Agility has been proposed as a response to the high levels of complexity and uncertainty in modern markets. It is a business-wide capability that embraces organizational structures, information systems and logistics processes. This study employs the hierarchical fuzzy MCDM algorithm proposed by Karsak and Ahiska for the evaluation of agile suppliers. This algorithm is based on the proximity to the ideal solution concept and it can address the problems containing both crisp and fuzzy data. The application of the decision making method is illustrated through a case study conducted in a privet hospital and the results are analysed.

  20. Postirradiation effects in alanine dosimeter probes of two different suppliers

    International Nuclear Information System (INIS)

    Anton, Mathias

    2008-01-01

    The measurand relevant for the dosimetry for radiation therapy is the absorbed dose to water, D W . The Physikalisch-Technische Bundesanstalt (PTB) is establishing a secondary standard for D W for high-energy photon and electron radiation based on electron spin resonance (ESR) of the amino acid alanine. For practical applications, like, for example, intercomparison measurements using the ESR/alanine dosimetry system, the temporal evolution of the ESR signal of irradiated probes is an important issue. This postirradiation behaviour is investigated for alanine pellets of two different suppliers for different storage conditions. The influence of the storage conditions on the temporal evolution may be dependent on the type of probes used. The measurement and analysis method developed at the PTB is able to circumvent the apparent difficulties in the case of alanine/paraffin probes. Care has to be taken in case this method cannot be applied

    Full Text Available Since the mid 1990s, the global aircraft industry has been creating new solutions for product development. Risk-sharing partnerships with suppliers began to be established in an attempt to reduce investments and, consequentially, the dependence on loans. The partners began not only to invest in tooling, engineering and infrastructure, but also to participate more directly in the projects, in the investments and design activities, acquiring rights to future sales income of products. This contractual modality, called risk-sharing partnership, is the focus of this study. Specifically, it analyzes the risk-sharing partnerships made by Embraer during the projects of the ERJ-170/190 family of aircrafts. It also aims to justify these partnerships, considering the current global aircraft market conditions, evaluating the critical success factors, requirements and macro-economic conditions which supported the adoption of this new policy.

    New evidence shows expansion by Unilever palm oil suppliers is driving species extinction in Central Kalimantan, and fuelling climate change. In November 2007, Greenpeace released 'Cooking the Climate', an 82-page report summarizing the findings of a two-year investigation that revealed how the world's largest food, cosmetic and biofuel companies were driving the wholesale destruction of Indonesia's rainforests and peatlands through growing palm oil consumption. This follow-up report provides further evidence of the expansion of the palm oil sector in Indonesia into remaining rainforests, orang-utan habitat and peatlands in Kalimantan. It links the majority of the largest producers in Indonesia to Unilever, probably the largest palm oil corporate consumer in the world.

    New safety requirements for coal mines in the United States requires the installation of wireless two-way tracking systems. The Office of Miners' Health Safety and Training has demanded that the owners of West Virginia's 170 coal mines submit plans by July 31, 2007 that describe how and when they intend to procure communication and electonic tracking systems. An estimated 430 additional coal mines across the U.S. will be required to file their plans concerning communications and tracking equipment by June 15, 2009, according to the U.S. federal government's Mine Improvement and New Emergency Response (MINER) Act. Radio communication and leaky feeder systems are routine in Canada's hard rock mines. Several Ontario-based supply companies are well placed to take advantage of this opportunity. The plans of three Ontario suppliers regarding proposed communications systems, quotations, costs, and tracking are outlined. 3 figs.

    For the next nuclear power plant generation, REP 2000, the Engineering and construction Division (ED) and the Research and development Division (R and D) of Electricite de France are working together in the field of Instrumentation and Control (I and C) to improve its engineering method and tools. This method and these tools are defined on the basis of the experience feedback from the N4 nuclear power plant generation and the current information technology, to improve engineering competitiveness and quality of control applications. We intend to decouple the I and C processing from the I and C Human Machine Interface (HMI), because methods and tools are different. In this paper, we only focus on method and tools for I and C processing. We define the I and C processing life cycle into three phases. The first phase is the specification of the control application processing, the product of which is called Functional Requirement Diagrams (FRDs). The second phase is the design of the I and C system. This phase is subdivided into two steps. The step 1 is the distribution of the FRDs into an I and C architecture. The step 2 is the allocation of resources of the I and C system, to support the distributed FRDs. The third phase is the implementation of the distributed FRDs into I and C equipment. The aim of the Engineering Division is to achieve formal FRDs, independent of I and C suppliers. This allows a large improvement for the quality of the specification and the dimensioning of the I and C system before calls for tenders. For the specification phase, studies are almost completed. For the design and the implementation phases, studies and experiments are in progress with European I and C system suppliers. As a conclusion, we present the interest of EDF for standards and especially IEC 1131 improvements. (author). 5 figs

    Counterfeiting of industrial and commercial grade items is an international problem that places worker safety, program objectives, expensive equipment, and security at risk. In order to prevent the introduction of Suspect/Counterfeit Items (S/CI), this information sheet is being made available as a guide to assist in the implementation of S/CI awareness and controls, in conjunction with subcontractor's/supplier's quality assurance programs. When it comes to counterfeit goods, including industrial materials, items, and equipment, no market is immune. Some manufactures have been known to misrepresent their products and intentionally use inferior materials and processes to manufacture substandard items, whose properties can significantly cart from established standards and specifications. These substandard items termed by the Department of Energy (DOE) as S/CI, pose immediate and potential threats to the safety of DOE and contractor workers, the public, and the environment. Failure of certain systems and processes caused by an S/CI could also have national security implications at Los Alamos National Laboratory (LANL). Nuclear Safety Rules (federal Laws), DOE Orders, and other regulations set forth requirements for DOE contractors to implement effective controls to assure that items and services meet specified requirements. This includes techniques to implement and thereby minimizing the potential threat of entry of S/CI to LANL. As a qualified supplier of goods or services to the LANL, your company will be required to establish and maintain effective controls to prevent the introduction of S/CI to LANL. This will require that your company warrant that all items (including their subassemblies, components, and parts) sold to LANL are genuine (i.e. not counterfeit), new, and unused, and conform to the requirements of the LANL purchase orders/contracts unless otherwise approved in writing to the Los Alamos National Security (LANS) contract administrator

    2016-08-01

    The development of a centralised and sustainable heat supply through the construction of heat grids offers consumers numerous advantages compared to a decentralised energy supply of residential and commercial properties. Where the migration to centralised heat supply relegates fossil fuels through the long-term incorporation of sustainable renewable energy sources, the projects make an important contribution towards meeting the government's climate protection goals. Heat generation and heat sales from renewable energy sources should be ensured in the long term. In the countryside, biogas plant operators are frequently the initiators of heat grid investments, or they take on the role of supplier for the provision of low-cost CHP heat from cogeneration units. In view of the limited remuneration period under the terms of the German Renewable Energy Act, the clock is ticking for the establishment of a centralised heat supply. This paper presents the advantages and disadvantages of a centralised, sustainable heat supply and additionally considers the flexibi/isation of biogas plants in view of the construction of the heat grid and the associated infrastructure. A focus is placed on the security of supply for customers after the discontinuation of remuneration under the German Renewable Energy Act and on how a competitive heat price from alternative energy sources can continue to be ensured.

  10. Initiation but no execution - modulation of peripheral blood lymphocyte apoptosis in rheumatoid arthritis - a potential role for heat shock protein 70

    Full Text Available Abstract Background Rheumatoid arthritis (RA is a chronic autoimmune disease, which causes synovial damage. Persistence of lymphocyte infiltrates in the rheumatoid synovium has been attributed to abnormal apoptosis. While not comprehensively investigated, perturbations in peripheral blood lymphocyte (PBL apoptosis may also be involved in perpetuation of autoimmune processes in RA. Methods We investigated total, CD4+ and CD19+ PBL apoptosis in our study cohort by monitoring the translocation of phosphatidylserine using the Annexin-V assay. To examine the role of death receptor mediated apoptosis as well as activation-induced-cell-death (AICD, PBLs were labeled with CD95/Fas and CD69 markers and enumerated by flow cytometry. Proteolytic activity of initiator and executioner caspases was determined by luminometry. DNA fragmentation assays were used to examine whether apoptotic signals were transduced to the nucleus. Quantitative PCR arrays were used to investigate apoptotic pathways associated with RA-PBLs. Since heat-shock-protein-70 (HSP70 is an inducible protein which modulates apoptotic signals, we determined HSP70 levels by intra-cellular flow cytometry and western blots. Results The RA-PBLs showed signs of elevated apoptosis whilst in circulation. These include increases in the loss of plasma membrane asymmetry, indicated by increased externalization of phosphatidylserine (especially in B-lymphocytes. RA-PBLs showed a bias to CD95/Fas mediated apoptotic pathways, but low levels of the CD69 marker suggested that this was not associated with immune activation. Although downstream markers of apoptosis such as caspase-3/7 activity, were increased, no DNA fragmentation was observed in RA-PBLs. Interestingly, elevated levels of apoptosis did not correlate with absolute lymphocyte counts in RA patients. Levels of HSP70 were highly elevated in RA-PBLs compared to controls. Conclusion The results suggest that while apoptosis may be initiated in RA

    2012-04-01

    Full Text Available Evaluation of proper supplier for manufacturing organizations is one of the most challenging problems in real time manufacturing environment due to a wide variety of customer demands. It has become more and more complicated to meet the challenges of international competitiveness and as the decision makers need to assess a wide range of alternative suppliers based on a set of conflicting criteria. Thus, the main objective of supplier selection is to select highly potential supplier through which all the set goals regarding the purchasing and manufacturing activity can be achieved. Because of these reasons, supplier selection has got considerable attention by the academicians and researchers. This paper presents a combined multi-criteria decision making methodology for supplier evaluation for given industrial applications. The proposed methodology is based on a compromise ranking method combined with Grey Interval Numbers considering different cardinal and ordinal criteria and their relative importance. A ‘supplier selection index’ is also proposed to help evaluation and ranking the alternative suppliers. Two examples are illustrated to demonstrate the potentiality and applicability of the proposed method.

    2009-01-01

    Full Text Available The relationship between buyers and suppliers has received considerable attention in recent years. There are fourth major questions being discussed in this research, i.e. firstly, how to determine the support of the top management to influence strategic purchasing; secondly, how to determine the influence of strategic purchasing to good communication and collaboration with supplier; and thirdly, how to determine the influence of communication and collaboration to supplier involvement; and the last, how to increase enterprise performance by collaboration and supplier involvement. Based on previous research, it is found that top management support influenced to strategic purchasing and effect to communication and collaboration and affect to supplier involvement. Collaboration and supplier involvement have been to influence enterprise performance. According survey by questionnaires to 105 respondent and 98 completed questionnaires were returned. Two responses were considered incomplete and had to be discarded, and this left 96 valid responses. It is found, top management support as an organization don’t have influenced strategic purchasing, but strategic purchasing have impact to communication and collaboration to supplier involvement. Collaboration will bring significant contribution to increase performance, even without the supplier involvement.

  5. Where to place the saving obligation: Energy end-users or suppliers?

    International Nuclear Information System (INIS)

    Bertoldi, Paolo; Labanca, Nicola; Rezessy, Silvia; Steuwer, Sibyl; Oikonomou, Vlasis

    2013-01-01

    Obligations to save energy differentiate, among other features, by obliged parties. These are obligations on energy suppliers and energy end-users. Supplier obligations have been introduced in North America, Europe and Australia. Under supplier obligations energy suppliers have to comply with mandatory energy saving targets and thus they implement (directly or via third parties) energy efficiency projects on their clients’ premises, or they decide to trade certified project savings if this option is envisaged by their obligation scheme. In several emerging schemes such as the UK Carbon Reduction Commitment (CRC) Energy Efficiency Scheme, the Tokyo Emission Trading Scheme or the Perform Achieve and Trade (PAT) Scheme in India, the obligation to reduce energy consumption is placed on large end-users directly and end-users are allowed to trade emissions allowances or energy saving certificates. The paper starts with presenting these two conceptually different ways for introducing energy saving obligations. Then it analyses advantages and disadvantages of end-users obligations compared to suppliers obligations. The preliminary conclusion of the paper is that supplier obligations seem to be well-suited for the residential sector, but end-user saving obligations may offer advantages when it comes to the industrial and commercial sectors. - Highlights: • We present different ways for introducing energy saving obligations. • We analyse energy end-users obligations vs. supplier obligations. • Supplier obligations seem to be well-suited for the residential sector. • End-user obligations offer advantages in the industrial and commercial sectors

    2013-07-01

    Full Text Available The public sector is recognised as being one of the most important customer groups for many suppliers and service providers because of the volume of public expenditure. Supplier relationship management (SRM is a necessary tool on which businesses in the public and private sectors rely. However, in the South African public sector, despite the intention to boost service delivery through efficient and effective supplier-management processes, the development of sound supplier relationships is a challenge. The purpose of this article is to provide insight into supplier-relationship challenges and to suggest a framework for implementing SRM in the South African public sector. The research presented is based on a survey using both descriptive and exploratory research. Data were gathered through semi-structured interviews with 15 participants at eight institutions in KwaZulu-Natal. Purposive sampling techniques were used. The findings reveal that the main supplier-related challenges that handicap procurement practices in the province are a lack of experience, a lack of affirmable suppliers, threats and bribes, a lack of integrity, an inability to meet delivery deadlines and quality issues. The findings further reveal that supplier relationships in the public sector are of a transactional nature. A five-stage framework is therefore recommended for implementing SRM in the South African public sector and in order to assist government procurement officials to reap the benefits of SRM whilst supporting the requirements of public-sector procurement.

    Full Text Available Engineering equipment is essential part in the construction project and usually manufactured with long lead times, large costs and special engineering requirements. Construction manager targets that equipment to be delivered in the site need date with the right quantity, appropriate cost and required quality, and this entails an efficient supplier can satisfy these targets. Selection of engineering equipment supplier is a crucial managerial process .it requires evaluation of multiple suppliers according to multiple criteria. This process is usually performed manually and based on just limited evaluation criteria, so better alternatives may be neglected. Three stages of survey comprised number of public and private companies in Iraqi construction sector were employed to identify main criteria and sub criteria for supplier selection and their priorities.The main criteria identified were quality of product, commercial aspect, delivery, reputation and position, and system quality . An effective technique in multiple criteria decision making (MCDM as analytical hierarchy process (AHP have been used to get importance weights of criteria based on experts judgment. Thereafter, a management software system for Evaluation and Selection of Engineering Equipment Suppliers (ESEES has been developed based on the results obtained from AHP. This model was validated in a case study at municipality of Baghdad involved actual cases of selection pumps suppliers for infrastructure projects .According to experts, this model can improve the current process followed in the supplier selection and aid decision makers to adopt better choices in the domain of selection engineering equipment suppliers.

    2010-11-01

    With over 5, 660 MW installed in end-2010, France ranks fourth in Europe, behind Germany, Spain and Italy. The wind power industry currently employs almost 11, 000 people in France throughout the value chain. In 2009, the first edition of this directory listed over one hundred companies working in around twenty different areas. Encouraged by these initial positive results, and with the help of ADEME, the French syndicate for renewable energies (SER) asked Capgemini Consulting to undertake a study to identify and raise awareness among French industrials likely to enter into the wind energy market. The French Ministry for Ecology, Energy, Sustainable Development and the Sea, along with the Ministry for the Economy, Finance and Employment, were involved in the work. 400 companies were questioned as part of the study. Over 150 replies testified to the dynamic character of the wind power market in France and overseas, and the opportunities for diversification that it represents for traditional industries like metallurgy, aeronautics, defence and shipyards, etc. The study led to the creation of the initiative Windustry France, which currently groups over 300 companies either active in the French wind power market or set to enter it. Windustry France is a showcase of the industrial know-how that can be used in the wind power industry both onshore and offshore. It includes local set-ups developed around major fields of activity (e.g. car industry, aeronautics, mechanics, etc.) and industrial port zones (Dunkerque, Rouen/Le Havre, Brest, Nantes Saint-Nazaire, Bordeaux, etc.). Several ministries, regional stakeholders and authorities are also involved (local authorities, Regional directorates for industry, research and the environment (DReal) networks and chambers of commerce and industry), all of which contribute to making Windustry France a collective approach to industrial policy.

    Supplier selection is a decision with many criteria. Supplier selection model usually involves more than five main criteria and more than 10 sub-criteria. In fact many model includes more than 20 criteria. Too many criteria involved in supplier selection models sometimes make it difficult to apply in many companies. This research focuses on designing supplier selection that easy and simple to be applied in the company. Analytical Hierarchy Process (AHP) is used to weighting criteria. The analysis results there are four criteria that are easy and simple can be used to select suppliers: Price (weight 0.4) shipment (weight 0.3), quality (weight 0.2) and services (weight 0.1). A real case simulation shows that simple model provides the same decision with a more complex model.

    Full Text Available In product development close collaboration between systems integrators and suppliers is important. The purpose of this article is to investigate the impact of the work breakdown structure (WBS and work packages (WPs in product development on the possibility of carrying through the strategy of supplier involvement into collaborative practice and to investigate how supplier involvement can be improved by altering the design of collaborative WBS and WP structures. Dependence Structure Matrix (DSM is introduced in order to analyse, visualise and manage interdependencies, in terms of information exchange between the systems integrator and supplier. This article shows how DSM can support the alternative design of integrated and collaborative WBS and integrated WPs following the logic of dependencies and the flow of information in order to support a strategy focusing on integration of suppliers on project and team level.

Due to the fact that in today's supply chain management, the performance of potential suppliers is evaluated against multiple criteria rather than taking into account only the cost factor, the appropriate criteria in the supplier selection have been identified, and the considered variants are assessed, considering the decision maker’s preferences and existing constraints. The variants are ranked in terms of their suitability for selecting a supplier with the use of Electre III method. The results obtained from the simulation experiment suggest that this methodology is a feasible decision support model.

    Full Text Available Supplier selection is a widely considered issue in the field of management, especially in quality management. In this paper, in the selection of suppliers of electronic components we used the integrated QFD and fuzzy AHP approaches. The QFD method is used as a tool for translating stakeholder needs into evaluating criteria for suppliers. The fuzzy AHP approach is used as a tool for prioritizing stakeholders, stakeholders’ requirements, evaluating criteria and, finally, for prioritizing suppliers. The paper showcases a case study of implementation of the integrated QFD and fuzzy AHP approaches in the selection of the electronic components supplier in one Serbian company that produces electronic devices. Also presented is the algorithm of implementation of the proposed approach. To the best of our knowledge, this is the first implementation of the proposed approach in a Serbian company.

    systems. The item acquisition lead times of suppliers are random variables. Backorder is allowed and shortage cost is charged based on not only per unit in shortage but also per time unit. Continuous review (s,Q) policy has been assumed. When the inventory level depletes to a reorder level, the total...... order is split among n suppliers. Since the suppliers have different characteristics, the quantity ordered to different suppliers may be different. The problem is to determine the reorder level and quantity ordered to each supplier so that the expected total cost per time unit, including ordering cost......, procurement cost, inventory holding cost, and shortage cost, is minimized. We also conduct extensive numerical experiments to show the advantages of our model compared with the models in the literature.

    Jardim, Kevin P.

    Supplier performance that meets the requirements of the customer has long plagued quality professionals. Despite the vast efforts by organizations to improve supplier performance, little has been done to standardize the plan to improve performance. This project presents a guideline and problem-solving strategy using a Define, Measure, Analyze, Improve, and Control (DMAIC) structured tool that will assist in the management and improvement of supplier performance. An analysis of benchmarked Quality Improvement Plans indicated that this topic needs more focus on how to accomplish improved supplier performance. This project is part of a growing body of supplier continuous improvement efforts. With the input of Zodiac Aerospace quality professionals this project's results provide a solution to Quality Improvement Plans and show objective evidence of its benefits.

    2014-01-01

    Full Text Available We introduce a wholesale pricing strategy for an incumbent supplier facing with a competitive counterpart. We propose a profit function which considers both the present loss and future loss from a wholesale price and then study the optimal wholesale prices for different objectives about this profit function for the incumbent supplier. First, we achieve an optimal wholesale price for the incumbent supplier to maximize his expected profit. Then, to reduce the risk originating from the fluctuation in the competitive supplier’s wholesale price, we integrate the conditional value-at-risk (CVaR measure in financial risk management into this study and derive an optimal wholesale price to maximize CVaR about profit for the incumbent supplier. Besides, the properties of the two optimal wholesale prices are discussed. Finally, some management insights are suggested for the incumbent supplier in a competitive setting.

    2016-01-01

    Full Text Available In today’s highly competitive environment, organizations need to evaluate and select suppliers based on their manufacturing strategy. Identification of supply chain strategy of the organization, determination of decision criteria, and methods of supplier selection are appearing to be the most important components in research area in the field of supply chain management. In this paper, evaluation of suppliers is done based on the balanced scorecard framework using new distance measure in fuzzy TOPSIS by considering the supply chain strategy of the manufacturing organization. To take care of vagueness in decision making, trapezoidal fuzzy number is assumed for pairwise comparisons to determine relative weights of perspectives and criteria of supplier selection. Also, linguistic variables specified in terms of trapezoidal fuzzy number are considered for the payoff values of criteria of the suppliers. These fuzzy numbers satisfied the Jensen based inequality. A detailed application of the proposed methodology is illustrated.

    2012-04-15

    Local Village Heating project relates to smaller villages which are located outside existing or planned district heating areas in Denmark. The analysis phase of Local Village Heating has shown that the concept can be the most feasible common heating system for villages that: 1. has a high building density - the buildings must be placed close together; 2. at least one large heat consumer, school, elder home or company is present in the village; 3. the number of buildings/households in the village is less than approx. 100. The analysis has shown that it is theoretical possible to establish a controlling system for the combined supplier/consumer option and an overall system for prioritizing the primary heat suppliers. A feasible Local Village Heating organisation could be a cooperative similar to other supply systems, such as common water supply and waste water cooperative. (Author)

  12. Addressing the Challenges of Sharing Lessons Learned Amongst Suppliers in a Fragmented and Competitive Marketplace

    International Nuclear Information System (INIS)

    Dennier, D.

    2016-01-01

    Historically, COG member utilities largely drew from in-house supporting functions or the original plant designers, allowing active sharing of operational and human performance experience amongst a small number of relevant parties. As the industry has evolved, utilities have increasingly drawn upon a greater number of independent external suppliers to provide goods and services. This diversification in supplier base within a competitive environment changes operating dynamics, as a safety culture-focused supplier must remain mindful of developing and retaining competitive advantages over other suppliers. A market-driven perspective may undermine the likelihood of sharing certain lessons learned and best practices for fear of weakening competitive position. Utility procurement procedures must ensure fair markets to be effective, but in doing so may limit opportunity for collaboration between supplier and utility compared to historic levels. Vibrant competitive markets attract a large number of suppliers, which adds to the complexity of effective sharing and absorption of industry lessons learned. This paper will explain the activities underway through the COG Supplier Participant program to remove impediments and share industry-wide operational lessons learned and best practices. (author)

  13. SUPPLIER SELECTION CRITERIA IN A POWER UTILITY IN MALAYSIA: ENGINEERS’ PERCEPTIONS

    Directory of Open Access Journals (Sweden)

    Sivadass Thiruchelvam

    2012-06-01

    Full Text Available Supplier selection of electricity generating, transmitting and distributing systems is part of the problem-solving environment in a power utility because it is a long-term investment for the organisation. Therefore, the decision over supplier selection directly influences the operational and financial position of a power utility. In addition, the supplier selection of a power-related system is a complex multi-criteria decision problem. While some criteria may be common across different industries, there are some criteria unique to the power industry. This research aims to understand what constitutes the suitable supplier selection criteria for a power utility. This study reveals some interesting findings of how engineers perceive the importance of each criterion and suggests strongly that product quality, price and delivery are key determinants in the supplier evaluation process. The eighteen criteria considered for this study were mapped onto their respective cluster, namely: supplier’s organisational system and technology, buyer-supplier relationship and economic value. The findings of this study should assist various groups of stakeholders (e.g., suppliers, buyers and end users to gain a better understanding of social behaviour in making purchase decisions, particularly with regard to power utilities.

    Directory of Open Access Journals (Sweden)

    F K Bondinuba

    2016-07-01

    Full Text Available Effective and efficient management of suppliers within a supply chain is an essential requirement for improving organisational performance within construction companies. However, factors inherent within the supply chain of supplier-buyer exchanges such as culture, politics, dependence and trust may influence supplier relationship quality (SRQ. This research therefore seeks to identify the influence that these factors have upon SRQ in the Ghanaian construction industry and develop a conceptual framework that explains the interconnectivity between them. A literature review is used to develop a conceptual framework of the antecedents influencing supplier relationship quality. Primary ‘perception’ data obtained from 152 building material suppliers is used to test the proposed model using Partial Least Squares (PLS. Findings reveal that culture, politics, dependence and trust have a significant influence on relationship quality in supply chain collaborations amongst purchasers and suppliers of building materials. While politics has a strong influence on dependence, it also generates a negative influence on SRQ and trust. The research confirms the positive effect of trust and dependence in SRQ management and extends understanding of the influence of culture and politics. Practical implications suggest that managers of building material suppliers should focus upon building trust and dependence and be discouraged from over-reliance upon politics and political affiliations as a basis for long-term relationship building.

  16. A hybrid agent-based computational economics and optimization approach for supplier selection problem

    Full Text Available Supplier evaluation and selection problem is among the most important of logistics decisions that have been addressed extensively in supply chain management. The same logistics decision is also important in freight transportation since it identifies trade relationships between business establishments and determines commodity flows between production and consumption points. The commodity flows are then used as input to freight transportation models to determine cargo movements and their characteristics including mode choice and shipment size. Various approaches have been proposed to explore this latter problem in previous studies. Traditionally, potential suppliers are evaluated and selected using only price/cost as the influential criteria and the state-of-practice methods. This paper introduces a hybrid agent-based computational economics and optimization approach for supplier selection. The proposed model combines an agent-based multi-criteria supplier evaluation approach with a multi-objective optimization model to capture both behavioral and economical aspects of the supplier selection process. The model uses a system of ordered response models to determine importance weights of the different criteria in supplier evaluation from a buyers’ point of view. The estimated weights are then used to calculate a utility for each potential supplier in the market and rank them. The calculated utilities are then entered into a mathematical programming model in which best suppliers are selected by maximizing the total accrued utility for all buyers and minimizing total shipping costs while balancing the capacity of potential suppliers to ensure market clearing mechanisms. The proposed model, herein, was implemented under an operational agent-based supply chain and freight transportation framework for the Chicago Metropolitan Area.

    The need for accurate and complete information and the need to have the information in a timely manner are needs which permeate the Guidelines of the Nuclear Suppliers Group (NSG), both Parts 1 and 2. In response to these needs, the US Department of Energy is sponsoring the development and deployment of a computerized information sharing system among all of the member states of the NSG and at the Permanent Mission of Japan in Vienna, the NSG Point of Contact or Secretariat. The system when fully deployed and operation will be supportive of both the nuclear nonproliferation objectives and the commercial interests of the member states by access to a wide range of policy and technical information. The NSG Information Sharing System, or NISS, has three major components. The first feature of the NISS is its ability to rapidly transmit notifications of export denials to export control officials in the capitals of the member states. An electronic mail capability will provide a means of informal communications among persons engaged in all aspects of the work of the NSG, including license review and preparation for the meetings of the Group. A final feature of the NISS is its ability to provide rapid access to a comprehensive library of reference documents and a complete and up-to-date set of records of the NSG meetings

    Fu, Yelin; Keung Lai, Kin; Liang, Liang

    2016-03-01

    We formulate the supplier selection and allocation problem in outsourcing under an uncertain environment as a stochastic programming problem. Both the decision-maker's attitude towards risk and the penalty parameters for demand deviation are considered in the objective function. A service level agreement, upper bound for each selected supplier's allocation and the number of selected suppliers are considered as constraints. A novel robust optimisation approach is employed to solve this problem under different economic situations. Illustrative examples are presented with managerial implications highlighted to support decision-making.

    1999-06-01

    Full Text Available This paper describes the results of a preliminary study to determine the effective heating and cooling time constants of ionospheric currents in a simulated modulated HF heating, `beam painting' configuration. It has been found that even and odd harmonics of the fundamental ELF wave used to amplitude modulate the HF heater are sourced from different regions of the ionosphere which support significantly different heating and cooling time constants. The fundamental frequency and its odd harmonics are sourced in a region of the ionosphere where the heating and cooling time constants are about equal. The even harmonics on the other hand are sourced from regions of the ionosphere characterised by ratios of cooling to heating time constant greater than ten. It is thought that the even harmonics are sourced in the lower ionosphere (around 65 km where the currents are much smaller than at the higher altitudes around 78 km where the currents at the fundamental frequency and odd harmonics maximise.Key words.

    2001-02-01

    In addition to the consumer goods, capital goods offer a great potential for ecological and economic optimization. In view of this fact the project WiMonDi (Re-Use of Assembly Systems as new Business Fields), started in September 1998, focuses a marketable Remanufacturing and Re-Use of modules and components of assembly systems by using technically and organizationally continuous concepts. The objective of the closed Facility-Management-System is to prolong the serviceable lifespan of assembly facilities through the organized dismantling, refurbishment and reconditioning of the assembly facilities as well as their components. Therefore, it is necessary to develop easible and methodical strategies to realize a workable Re-Use concept. Within the project the focus is based on the optimization of Re-Use-strategies - the direct Re-Use, the Re-Use including Refurbishment as well as Material Recycling. The decision for an optimal strategy depends on economical (e.g. residual value, cost/benefit of relevant processes, etc.), ecological (e.g. pollutant components /substances), etc.) and technical parameters (e.g. reliability, etc.). For the purpose to integrate the total cost-of-ownership of products or components, WiMonDi integrates the costs of the use of products as well as the Re-Use costs/benefits. To initiate the conception of new distribution and user models between the supplier and the user of assembly facilities the described approach is conducted in close cooperation between Industry and University.

    International Nuclear Information System (INIS)

    Hamm, L.L.

    1998-01-01

    A transient natural convection model of the APT blanket primary heat removal (HR) system was developed to demonstrate that the blanket could be cooled for a sufficient period of time for long term cooling to be established following a loss-of-flow accident (LOFA). The particular case of interest in this report is a complete loss-of-pumping accident. For the accident scenario in which pumps are lost in both the target and blanket HR systems, natural convection provides effective cooling of the blanket for approximately 68 hours, and, if only the blanket HR systems are involved, natural convection is effective for approximately 210 hours. The heat sink for both of these accident scenarios is the assumed stagnant fluid and metal on the secondary sides of the heat exchangers

    This paper looks at current experiences of geospatial users and geospatial suppliers and how they have been limited by suitable frameworks for managing and communicating data quality, data provenance and intellectual property rights (IPR). Current political and technological drivers mean that increasing volumes of geospatial data are available through a plethora of different products and services, and whilst this is inherently a good thing it does create a new generation of challenges. This paper consider two examples of where these issues have been examined and looks at the challenges and possible solutions from a data user and data supplier perspective. The first example is the IQmulus project that is researching fusion environments for big geospatial point clouds and coverages. The second example is the EU Emodnet programme that is establishing thematic data portals for public marine and coastal data. IQmulus examines big geospatial data; the data from sources such as LIDAR, SONAR and numerical simulations; these data are simply too big for routine and ad-hoc analysis, yet they could realise a myriad of disparate, and readily useable, information products with the right infrastructure in place. IQmulus is researching how to deliver this infrastructure technically, but a financially sustainable delivery depends on being able to track and manage ownership and IPR across the numerous data sets being processed. This becomes complex when the data is composed of multiple overlapping coverages, however managing this allows for uses to be delivered highly-bespoke products to meet their budget and technical needs. The Emodnet programme delivers harmonised marine data at the EU scale across seven thematic portals. As part of the Emodnet programme a series of 'check points' have been initiated to examine how useful these services and other public data services actually are to solve real-world problems. One key finding is that users have been confused by the fact that often

    At the last moment Kosice managed to overcome the threat of a more than 30-percent heating price increase. The biggest local heat producer, Teplaren Kosice, is running out of coal supplies. The only alternative would be gas, which is far more expensive. The reason for this situation was a dispute of the heating plant with one of its suppliers, Kimex. Some days ago, the dispute was settled and the heating plant is now expecting the first wagon loads of coal to arrive. These are eagerly awaited, as its supplies will not last for more than a month. It all started with a public tender for a coal supplier. Teplaren Kosice (TEKO) announced the tender for the delivery of 120,000 tons of coal in June. Kimex, one of the traditional and biggest suppliers, was disqualified in the course of the tender. The winners of the tender were Slovenergo, Bratislava and S-Plus Trade, Vranov nad Toplou. TEKO signed contracts with them but a district court in Kosice prohibited the company from purchasing coal from these contractors. Kimex filed a complaint claiming that it was disqualified unlawfully. Based on this the court issued a preliminary ruling prohibiting the purchase of coal from the winners of the tender. The heating plant had to wait for the final verdict. The problem was then solved by the company's new Board of Directors, who were appointed in mid October who managed to sign new contracts with the two winners and Kimex. The new contracts cover the purchase of 150-thousand tons of coal, which is 30,000 more than in the original tender specification. Each company will supply one third. (authors)

    Full Text Available This study proposes a novel hybrid multiple-criteria decision-making (MCDM method to evaluate green suppliers in an electronics company. Seventeen criteria in two dimensions concerning environmental and management systems were identified under the Code of Conduct of the Electronic Industry Citizenship Coalition (EICC. Following this, the Decision-Making Trial and Evaluation Laboratory (DEMATEL used the Analytic Network Process (ANP method (known as DANP to determine both the importance of evaluation criteria in selecting suppliers and the causal relationships between them. Finally, the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR method was used to evaluate the environmental performances of suppliers and to obtain a solution under each evaluation criterion. An illustrative example of an electronics company was presented to demonstrate how to select green suppliers.

    Full Text Available Supplier selection is a complex multi-criteria problem which includes both qualitative and quantitative criteria.  In order to select the suppliers, it is necessary to make a tradeoff between these criteria some of which may conflict. Different approaches are suggested to solve the supplier selection problem in the literature. Especially, Saaty’s analytic hierarchy process (AHS is more useful approach for the problem, because of its inherent capability to handle qualitative and quantitative criteria.The main purpose of this study is to solve the supplier selection problem of the textile firm by using AHS.  The proposed model consists of a hierarchical network of connections among five alternatives, seven main and thirteen sub criteria. Twenty-one pairwise comparison matrices were obtained by using focus group methodology.  The results are presented and the sensitivity analyses are performed. Finally, some suggestions and important clues for the management are presented.

    The purpose of this research is to develop a concurrent supplier selection model to minimize the purchasing cost and fuzzy quality loss considering process capability and assembled product specification. Design/methodology/approach: This research integrates fuzzy quality loss in the model to concurrently solve the decision making in detailed design stage and manufacturing stage. Findings: The resulted model can be used to concurrently select the optimal supplier and determine the tolerance of the components. The model balances the purchasing cost and fuzzy quality loss. Originality/value: An assembled product consists of many components which must be purchased from the suppliers. Fuzzy quality loss is integrated in the supplier selection model to allow the vagueness in final assembly by grouping the assembly into several grades according to the resulted assembly tolerance.

    Full Text Available The purpose of this study was to investigate the influence of intellectual capital of Turkish automotive supplier industry upon their innovation performance. This study showed that three types of intellectual capital – employee capital, structural capital, and customer capital – had a significantly positive relationship with innovation performance. Moreover, the results also indicated that the higher the growth rate of an industry, the stronger were the positive relationships between three types of intellectual capital and innovation performance. Besides, customer capital was the greatest among these three types of intellectual capital in Turkish automotive supplier industry, employee capital was the next, and structural capital was the least. This shows two points; first, Turkish automotive supplier industry emphasized the interactive “relations” with their suppliers, clients, and partners; second, it was imperative for Turkish manufacturing enterprises to develop their structural capital to increase their innovation performance.

    basis, most often only once per month. In addition lead-times are long, as the suppliers are situated overseas.  Therefore the company must keep all the inventories at considerable costs. The company wishes to make contracts with its suppliers such that they keep some reserve inventory that can...... be accessed (at a higher unit price than the normal one) but also with a shorter lead-time. Furthermore the company must also pay a cost proportional to inventory level for maintaining this reserve inventory. This problem can be considered as an inventory control model with two suppliers. We propose a dynamic......This work inspired by a contact with a larger telecommunication company. Many of the products offered are unique for this company and they also have very short lifetimes, normally about 18 months. Furthermore the suppliers do not wish to keep any inventories and they only accept orders on periodic...

    Full Text Available The purpose of the paper is to explore the supplier relationship practices of travel agencies in Gauteng. Gerber (2008 indicated that the current level of relationships that exists between travel agencies and their suppliers in Gauteng are fragmented and impact negatively on the ability of travel agents to deliver a quality service to their customers. It is against this background that the research was undertaken. The target population for this study was 228 travel agencies of which 134 managers and/or owners participated through personal interviews in the completion of questionnaires. The results indicate that the owners and managers of travel agencies are of the opinion that the level of trust between themselves and their suppliers needs to be strengthened. The stimulation of open channel communication between themselves and their suppliers could enhance the strengthening of a long-term relationship between the parties.

    Full Text Available The growing uncertainty of business environment that negatively influences the contemporary supply chains is one of the major challenges for today’s managers. The literature recommends the development of resistant supply chains, defining them as adaptive and flexible. However, there are a few scientific publications that directly link to the area of Supplier Relationship Management in this regard. The article aims to answer the question what is the flexibility and adaptability and how to perceive these two characteristics in terms of an upstream supply chain. The observations indicate that building relationships resistant to these disruptions with suppliers includes the formulation of appropriate strategies towards both the suppliers and the purchasing process. Their choice depends on the source of uncertainty and the costs of switching the suppliers
