    The subject of this paper is the implementation of a quality management system for suppliers of products and services for the petroleum and natural gas industry that meet the ISO TS 29001:2003 Standard requirements. This technical specification establishes supplementary requirements to ISO 9001:2000 Standard for the product and service suppliers of the petroleum and natural gas industries. It was the result of a partnership between API and ISO TC 67. It intends to become the common and unique reference for the quality management systems requirements for the industry in the world. Therefore, it helps to avoid multiple systems that ask multiple audits for the certification. The generality of the ISO 9001:2000 Standard, reference for the quality management system for any organization , independent of its size, activity and location, not always satisfies all requirements of the specific sectors.

    Natural gas, with its environmental advantages, will increase its development in the residential, professional and transportation markets. It will ensure the transition during the progressive implementation of more sustainable energy sources. This paper discusses some possible impacts of the deregulation on the future gas market (investments, risk management, competition, contracts). It is followed by a round table about the expectations of some gas producers (Qatar, Sweden) in front of the development of the European gas market (LNG projects, financing, contracts). (J.S.)

    Van Gelder, J.W.

    1999-01-01

    Deregulation in the energy sector has forced companies to scale up. Natural gas suppliers and installers are confronted with more pressure to cut prices and bigger turnover fluctuations. Companies doing business with gas companies try to escape the consequences of deregulation by developing new products and improving their services. In the sixth and last article in the series on the effects of the liberalisation of the Dutch gas market, suppliers express their concern about the changes triggered by the deregulated market. Challenges and opportunities of deregulation are discussed as well. The bigger companies in the installation sector will be looking for opportunities to render energy services independently or in co-operation with (foreign) partners. For smaller installers, however, co-operation seems to be an interesting option, either with other installers or with energy companies

    Full Text Available Purpose: In order to achieve excellence, outsourced maintenance contractors in Oil&Gas sector play a key role due to the important impact of their task on security, availability and energy consumption. This paper presents the process followed in order to implement a Supplier Development Program in a refinery using Company Maturity Model (CoMM and the results obtained in three cases validating the method to obtain a strategic improvement project medium term grid. Design/methodology/approach: The methodology followed consists of constructing a CoMM capturing the knowledge existing in the refinery and applying it with three supplier improvement teams. Findings and conclusions have arised through an observation of the three processes and extracting common conclusions. Findings: The resulting CoMM has been used for self-assessment by three suppliers and has demonstrated its potential to define a medium-term improvement project road map validated by the customer. Furthermore, during the design and application processes, the contribution of CoMMs to the SECI process of knowledge management has been observed. Practical implications: The use of CoMMs in a service contractor context can be applied in other sectors. It contributes to alignment of targets between the supplier and customer companies and to knowledge sharing inside both firms. Originality/value: Maturity models in many transversal fields (CMMI, EFQM, BPMM, PEMM, etc. have been thoroughly studied in the literature. Less effort has been made analysing the case of using maturity models constructed and implemented by a company for its specific purposes. In this paper, the process followed by a company to establish a Supplier Development Process using CoMMs is described.

  10. Presenting a Multi Objective Model for Supplier Selection in Order to Reduce Green House Gas Emission under Uncertion Demand

    Directory of Open Access Journals (Sweden)

    Habibollah Mohamadi

    2014-08-01

    Full Text Available Recently, much attention has been given to Stochastic demand due to uncertainty in the real -world. In the literature, decision-making models and suppliers' selection do not often consider inventory management as part of shopping problems. On the other hand, the environmental sustainability of a supply chain depends on the shopping strategy of the supply chain members. The supplier selection plays an important role in the green chain. In this paper, a multi-objective nonlinear integer programming model for selecting a set of supplier considering Stochastic demand is proposed. while the cost of purchasing include the total cost, holding and stock out costs, rejected units, units have been delivered sooner, and total green house gas emissions are minimized, while the obtained total score from the supplier assessment process is maximized. It is assumed, the purchaser provides the different products from the number predetermined supplier to a with Stochastic demand and the uniform probability distribution function. The product price depends on the order quantity for each product line is intended. Multi-objective models using known methods, such as Lp-metric has become an objective function and then uses genetic algorithms and simulated annealing meta-heuristic is solved.

    1996-01-01

    Gas-turbine technology has entered a new era; the simple-cycle units of yesterday are making room for new, highly sophisticated combined-cycle units. In July 1949, the first U.S. commercial power generation gas turbine was installed at Oklahoma Gas and Electric Co.'s Belle Isle Station. This unit was a General Electric (GE) MS3000 heavy-duty gas turbine rated at 3,5000 kW. In 1994, more than 900 gas turbines totaling over 33,000 MW were ordered worldwide, according to Power-Data Group, LaJolla, Calif. These figures show just how far gas turbines have come in less than 50 years. Today, simple-cycle units rated at up to 150 MW (with efficiencies around 35 percent) and combined-cycle units rated at over 200 MW (approaching 60-percent efficiency) are up and running

  15. Norwegian company suppliers for the oil and gas exploitation in Norway and abroad 2003

    2004-09-01

    The Institute for Research in Economics and Business Administration has for the forth time monitored how Norwegian suppliers to the petroleum activity find their way to various markets. The data are valid for activities during 2003. The study is carried out among 413 companies at the business level and for 21 at the corporation level. The companies are mainly small and middle sized while the corporations that comprises several companies, are to be considered as large in the Norwegian context. 204 of the small and middle sized companies replied. In the group of larger corporations about 95 % replied. As the latter group is responsible for 80-90 % of the turnover in the Norwegian petroleum sector the total estimates in the investigation should be quite accurate. More than 90 % of the registered sales abroad may be contributed to 22 companies. It should therefore be possible to catch important development characteristics in the petroleum sector by focusing on 30-40 companies. Another structural characteristic is that the companies involved in petroleum activities rarely involve themselves in pure research and development activities. The current innovation is made in the context of solving specific challenges connected to reservoir, ocean depth, climate and distance and usually in relation to customers and suppliers. The petroleum sector had an average turnover of 39 % in their trade with foreign countries in 2003 which is an increase. The majority of the companies have a registered sale abroad. The tendency is increasing. The petroleum regions that receive the majority of the Norwegian sales during 2003 as previously, are the UK/North Sea, the USA/Canada and South East Asia/Australia. The sales to the Western Africa and South America are also considerable. The petroleum sector in Norway has achieved market positions over almost the entire globe in less than 10 years. With the collected data material as a basis it is estimated a 34 thousand million NOK petroleum

  16. The influence of supplier assessment in the termination of oil and gas exploitation and production contracts in Brazil

    2016-03-01

    Full Text Available The supplier performance assessment literature shows that the prior identification of contracts considered unsatisfactory may prove crucial to the maintenance of a company, especially in sectors with high operational and environmental risk and significant investments, such as the oil and gas exploitation sector. Although considered important, contract termination has been little studied in the Brazilian oil segment, due to the small number of firms operating in the sector and restricted access to information from these companies. This article aims to reduce this gap by analyzing what service assessment criteria most influence contract terminations in the Brazilian sector of oil and gas exploitation and production. Therefore, the assessments of service contracts terminated between 1/1/2006 and 12/31/2014 by a business unit active in oil and gas exploitation and production located in Brazil were analyzed using logit regressions. In the resulting database, 273 contracts were found that include all specialized services in the activity, totaling 19,613 ratings. The results indicate that the Term and Logistics criteria reveal the greatest influence on contract cancelations of the sector activities. In addition, by segregating the analysis by specialty, it was found that different specialties have different requirements and therefore different contractual arrangements. These results empirically corroborate the theoretical discussions in the literature about the importance of compliance with contractual obligations, especially with regard to the negotiated deadlines.

  19. Cooperation between West and East German gas transmission companies - an example of collaboration with Eastern European gas suppliers

    Geweke, J.

    1994-01-01

    In the future, it can be assumed there will be a new quality of co-operation between the East and the West. The tremendous growth in demand for natural gas in Europe necessitates the development of new, increasingly distant gas resources. The investment required can not be raised by a few countries on their own. A strategy is needed for all states integrated in the European natural gas transmission system. Due to their geographic location, Eastern and Southern European countries have a key role to play. Central Europe will become the heart of the international natural gas business. Then the future co-operation between East and Western Europe must be taken into account. An important prerequisite for equal partners in the European gas industry will be coordination, if natural gas is to continue to make a growing contribution to an environmentally compatible and efficient energy supply in all European states and beyond.

    2010-01-01

    This paper examines the development of cooperative strategies between countries exporting Liquefied Natural Gas (LNG) and members of the Gas Exporting Countries Forum (GECF). This economic study focuses specifically on an often-raised scenario: the emergence of a cooperative approach designed with the sole aim of logistic rationalization, and which would not have any effect on LNG prices. We first assess the annual gains that may result from this market-power-free cooperative approach using a simple static transportation model. The numerical results obtained suggest that, in the absence of a gain redistribution policy, this cooperative strategy will probably not be adopted because cooperation would not be a rational move for some exporters. The problem of gain sharing is then formulated using cooperative game theory concepts. Several gain-sharing methods have been studied, including the Shapley value and various nucleolus-inspired concepts. Our results suggest that the choice of a redistribution policy appears relatively restricted. Out of the methods studied, only one - per capita nucleolus - satisfies two key requirements. core belonging and monotonicity (in the aggregate). Lastly, we look at how cooperation may give rise to a coordination cost and try to determine the maximum amount of this cost. In view of the low level of this amount and the relative complexity of the sharing method implemented, we consider that the credibility of a logistic cooperation scenario exempt from market power should be reappraised.

    This paper examines the development of cooperative strategies between 12 countries exporting Liquefied Natural Gas (LNG) and belonging to the Gas Exporting Countries Forum (GECF). This economic study is more specifically focused on a scenario often raised: that of the emergence of a cooperative approach designed with the sole aim of logistic rationalization, and which would not have any effect on LNG prices. As this is a standard transportation problem, we first assess the gains that may result from this cooperative approach using a simple static model calibrated on the year 2007. The numerical results obtained suggest that, in the absence of a gain redistribution policy, this cooperative strategy will probably not be adopted because cooperation would not be a rational move for some exporters. The problem of gain sharing is then formulated using cooperative game theory concepts. Several gain sharing methods have been studied, including the Shapley value and various nucleolus-inspired concepts. Our results suggest that the choice of a redistribution policy appears relatively restricted. Out of the methods studied, only one - the per capita nucleolus - satisfies two key requirements: core belonging and mono-tonicity (in the aggregate). Lastly, coordination costs are considered and we determine the maximum amount that can be tolerated by such a cooperation. In view of the low level of this amount and the relative complexity of the sharing method implemented, we consider that the credibility of a logistic cooperation scenario exempt from market power should be reappraised.

    Considerable misgivings concerning the quality assurance systems exist among the energy supply enterprises. However, the proper utilisation of these systems creates cost transparency, increases economic efficiency and promotes customer satisfaction. A working group comprising representatives of the insular works and the propane-air producers for peak demand have critically examined the quality requirements in the field of product, operation, application and management of the gas supply on the basis of a well-defined performance commission. The evaluation of the enquiry at the member plants showed that, especially concerning the gas quality, network management, operational security and the organisational procedures, a demand for an efficient quality management exists. For a long-term execution of the service commission a certification according to ISO 9000-Series is recommended. (orig.)

    José Felipe Figueiredo Barata

    2014-02-01

    Full Text Available The necessity of sustainability evaluation is rapidly growing alongside the expansion of civilization. Likewise, the supply chain suitability improvement is a need that has arisen in the petroleum industry, especially as it is responsible for the most part of CO2 emissions in the atmosphere. The modeling of this kind of problem deals with multiple criteria evaluations. This paper proposes an original multiple-criteria based approach to classifying the degree of organizational sustainability. This proposal was applied to evaluate a representative set of companies, which are suppliers of the Brazilian petroleum industry. The data collection was supported by a questionnaire. The results highlight that the studied companies have not yet reached an advanced level of maturity in the sustainability context. In a comprehensive vision of sustainability based on Triple Bottom Line (TBL, these companies are either in the initial stage or in the implementation phase of the sustainability practices.

  6. Natural gas corridors among the EU and its main suppliers. Simulation results with the dynamic GASTALE model

    2006-06-01

    European demand for natural gas has grown and is expected to expand considerably in the next decades. This growth is partly induced by the environmental policy targets, e.g., the Kyoto protocol, and the European energy market liberalisation. However, this development also poses a challenge for the energy consumers in the EU and other gas importing countries with respect to the increasing dependency on gas imports and consequently also the security of gas supplies. First, briefly the business-as-usual (BAU) scenario with a focus on the required gas infrastructure is presented. The analysis focuses on interactions among demand, supply and gas transport infrastructure, pipeline and LNG transport, storage, and necessary investments in the natural gas market over the period 2005-2030. For dealing with the great uncertainties that are part of our long term future, a number of policy scenarios in addition to the BAU case are formulated to study the impact of demand uncertainty and delaying investment behaviour on the gas transport infrastructure (pipeline transport, LNG facilities and storage capacity) required in the long run in Europe. In addition, some of the key tradeoffs among investments in pipelines, LNG liquifaction and regasification facilities, and storage capacity are investigated. The analyses in this paper indicate that substantial investments in gas transport corridors are needed to provide for security of supply. Especially the pipeline connections running from East to West need to be prioritised. The future gas price largely depends upon the sufficient availability of gas from Russia, Iran, and Central Asian countries

    An efficient management of the natural gas business chain, based on pipeline transmission network and taking into consideration the interaction between the main players such as shippers, suppliers, transmission companies and local distribution companies, requires the use of decision-making support systems to maximize resources and mitigate contingencies due to gas supply shortfalls, operational contingencies from scheduled and non-scheduled equipment outages as well as market demand shortfalls. This work presents a practical utilization of technologies such as thermohydraulic simulation of gas flow through pipelines, Monte Carlo simulation for compressor station availability studies and economic risk evaluation related to potential revenue losses and contractual penalties and linear programming for maximization and minimization objective function. The proposed system allows the definition of the optimum availability level to be maintained by the Transporter, by means of installing redundancy, to mitigate losses related to revenue and contractual penalties. Identifies, quantifies and justifies economically the installation of stand-by compressor units, mitigating Transporter exposure to losses due to capacity shortfalls as consequence of scheduled and non-scheduled outages.

    Growth in gas demand poses a challenge for European energy consumers and other gas-importing countries in terms of an increasing dependency on gas imports and consequently also supply security. This paper focuses on interactions among demand, supply, and investments in natural gas corridors, namely pipeline transport, LNG, and storage facilities, affecting the European natural gas market over the period 2005-2030. A number of policy scenarios, including a business-as-usual (BAU) scenario, are formulated to study the impact of demand uncertainty and delays in investment on the gas transport infrastructure required in the long run in Europe. The analyses indicate that substantial investments in gas transport corridors are needed to accommodate imports and seasonal demand variations. Analysis of scenarios of supply interruption, in the form of suddenly reduced import capacity for particular pipeline routes, indicates that portions of Europe could experience price increases of up to 100% in the case of a year-long interruption. To accommodate import needs and to mitigate possible disruptions, pipeline connections running from East to West need to be given special priority. (author)

    Growth in gas demand poses a challenge for European energy consumers and other gas-importing countries in terms of an increasing dependency on gas imports and consequently also supply security. This paper focuses on interactions among demand, supply, and investments in natural gas corridors, namely pipeline transport, LNG, and storage facilities, affecting the European natural gas market over the period 2005-2030. A number of policy scenarios, including a business-as-usual (BAU) scenario, are formulated to study the impact of demand uncertainty and delays in investment on the gas transport infrastructure required in the long run in Europe. The analyses indicate that substantial investments in gas transport corridors are needed to accommodate imports and seasonal demand variations. Analysis of scenarios of supply interruption, in the form of suddenly reduced import capacity for particular pipeline routes, indicates that portions of Europe could experience price increases of up to 100% in the case of a year-long interruption. To accommodate import needs and to mitigate possible disruptions, pipeline connections running from East to West need to be given special priority. (author)

    The Usiminas, Steelmaking Plant located in Ipatinga - MG, has the necessity to complement its energy matrix with additional fuel (oil derived from petroleum presently). Despite the high cost of this fuel, 24,3% of the LDG gas was wasted due to inadequate size of the LDG gas holder and the inappropriate tool to manage the distribution of the fuel. This paper presents how the Steelmaking Gas Prediction System was developed aiming to improve its management and other actions to increase the gas usage minimizing the matrix complementation.

  13. Electricity sales prospects for a landfill gas generator acting as a second tier supplier in England and Wales

    International Nuclear Information System (INIS)

    1996-01-01

    Following the liberalisation of the United Kingdom electricity market, there are now a growing number of companies trying to develop small generation projects based on a landfill gas fuel source. Because of their size they will typically be connected to the electricity distribution system and as such not using the transmission system -with all of the power typically being absorbed locally. In common with grid connected projects, these smaller 'embedded' generators must be able to: be connected to the system; have a market for their product; and be reasonably certain of the price they can receive for the power that they produce, in order to develop a business case and, if necessary raise finance for the scheme. Generators in England and Wales that have a capacity of less than 50MW do not need a Generation Licence, and as such have no 'natural' market for their power, even though it may be potentially more valuable than power sold by licensed generators into the Pool. The logical purchaser for this local power would normally be the host electricity supply company as they own and control the distribution network up to and including 132kV. (Author)

    This paper presents a new kind of alliance between a gas utility company (COMGAS - Sao Paulo - Brazil) and a meter supplier (Actaris). This partnership, being implemented in a new gas market, is in accordance with the modern energy regulatory strategies of development countries, for example the energy multiple transparency concepts. The scope of the contract between these two players is a meter park calibration and replacement program. Initially COMGAS meter park will be described according to a metrological point of view before the project, as well as, the reasons which drove COMGAS and Actaris to adopt this new contract philosophy. It will be mentioned also, the operational problems relating to the execution of this contract, the agreements with the Sao Paulo state energy regulator (CSPE) and the Brazilian metrological agency (INMETRO). Finally, the results of this alliance will be presented, emphasizing the gains obtained from the implementation of a fair metering policy and its cost-effectiveness, which demonstrates the viability of the application of modern energy market concepts relating to elaboration of partnerships between natural gas market players, in non consolidated gas markets, like the Brazilian natural gas market.

  16. 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

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

    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

    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

    The Brazilian Federal Government has the very purpose of increasing the participation of the Natural Gas in the primary energy internal supply from 7,5% nowadays to about 12% till 2010. However, for that, it is necessary to eliminate the great impedance represented by the restricted accessibility to the product, due to the high distribution costs involved. So, there is an urgent need for availability of technologies to help natural gas distribution systems. This paper proposes an innovative logistics-based approach on the subject of the natural gas distribution, through a computational tool (GASLOG System) to be applied in the North and Northeastern urban and country areas of Brazil, with initial case study in the city of Fortaleza. In its conception, the GASLOG System focuses on the point-of-view of everyone of the actors involved with the natural gas distribution process trying to respond their particular necessities in the sector.

    Since 1992, Transportadora de Gas del Sur (TGS) has been operating the longest gas pipeline system in South America. Prior to that date, the system was managed by GE, a state-owned company. Early on in the administration of the company, some improvement opportunities were identified in the technical, commercial, management and personnel fields. An integrated transformation process was developed which involved major investments, acquisition of new technology, re-design of the work force, and new work methodologies. The course of action followed by the company was based on an attempt to achieve permanent improvement on business results. This paper is the result of the improvements applied to our gas transportation system. Due to the time and cost assessment required by scheduled turbine compressor maintenance works (83 - 538.220 hp), a Contingency Plan for turbine compressor breakdowns was established as well as an Economic Dispatch, which can determine low-cost operations in specific periods of time (during the year).

The system is currently being developed by LASHIP-UFSC in partnership with PETROBRAS/CENPES and TBG. The SEGRED system consists of an environment designed to support natural gas pipeline management by means of remote supervision of process parameters and analysis of the mutual interactions of those parameters by an expert system integrated to a dynamic simulator. The system is deployed through a process that contributes to making available for use the knowledge about functions such as line packing analysis and line break detection, thus enhancing the quality of execution of these tasks, which are related to the management of natural gas transportation network. The main benefits consist of promoting efforts to acquire and organize expert knowledge. This process contributes to the generation of a knowledge base with corporate technical memory, which can be made available in a permanent, expansible and useful way for decision-making. (author)

    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.

    This paper presents a project to integrate expert system and dynamic simulation of natural gas transportation network applying the concept of agents. Natural gas pipeline operation requires the intermittent analysis of hundreds interrelated operational parameters, which represent the network state. The combination of expert system and dynamic simulation is a synergic solution for this kind of problem. With expert system techniques, it is possible to implement rules that describe the relationship between current operational parameters and the network normal operational conditions based on heuristic knowledge. By applying such rules, the system aims to evaluate the real network state and to predict abnormal conditions via dynamic simulation, allowing time analysis of operational situation in advance. At the current stage, the project presents a well defined model. The process of knowledge acquisition and representation has taken place following an incremental approach, considered as development paradigm. The project objectives are to reduce costs, increase the reliability and organize pipeline operation and maintenance information. This work is part of SEGRED project established as partnership among LASHIP/UFSC, SCGAS, TBG and PETROBRAS. The project also received support from FINEP. (author)

    CERN Multimedia

    Jenni, P

    The ATLAS Collaboration has recently rewarded two of its suppliers in the construction of very major detector components, fabricated in Japan. The ATLAS Supplier Award in recognition of excellent supplier performance was attributed on 2nd September 2002 during a ceremony in Hall 180 to Kawasaki Heavy Industries, while Toshiba Corporation received the award two months before at their headquarters in Japan. The ATLAS experiment will become a reality thanks to a large international collaboration partnership. The industrial suppliers for the components all over the world play a major role in the construction of this gigantic jigsaw for the LHC. And sometimes they perform so well, that their work deserves specially to be recognised. This is the case for Kawasaki Heavy Industries and Toshiba Corporation, producers of the Liquid Argon Barrel Cryostat and of the Superconducting Central Solenoid, respectively. With these awards, the ATLAS Collaboration wants to congratulate Kawasaki and Toshiba for fulfilling the hi...

  15. 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)

  3. 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.

    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.

  6. Supplier Selection Using Fuzzy Inference System

    Directory of Open Access Journals (Sweden)

    hamidreza kadhodazadeh

    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.

  7. Studying the emerging nuclear suppliers

    International Nuclear Information System (INIS)

    Rydell, R.F.

    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

  12. Supplier selection using different metric functions

    Directory of Open Access Journals (Sweden)

    Omosigho S.E.

    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.

    This paper presents the Conversion Project of Rio de Janeiro, Brazil, that converted all customers and the distribution network from Manufactured Gas (MG) to Natural Gas (NG), evaluating its logistic and benefits, highlighting those related to consumer safety. The Conversion Project was executed under the responsibility of CEG with the support of UERJ, specially on the definition and revision of the technical procedures as well as the quality assurance of the project execution. As main advantages followed by MG to NG network conversion, we can note: increasing of gas distribution network capacity and gas network operational condition improvements; elimination of production plant; revision and renovation of gas network; revision and repairing of building gas facilities; augmenting of NG usage; elimination of carbon monoxide as a supplied gas constituent. Conservation condition of most consumer internal gas facilities and ambient ventilation were so critical that conversion program resulted in no measurable accident prevention. The achieved safety level should be maintained through a periodically re-evaluation program of customer's gas facilities and appliances, with special focus on permanent ventilation required for NG safety usage.

    Considering the wide increase of natural gas participation in the Brazilian energetic source matrix, this paper describes, comments and analyzes how the natural gas flow measurement process has been structured in PETROBRAS, so that it become a potential factor of this increase. Initially, the work makes a metrological approach of measured volumes, based on volumetric balance of the gas flow in the two principals pipe segments of PETROBRAS gas line network, localized in the Brazilian southeast and northeast systems. This approach runs through the investigation of several parameters that have influence on that balance, considering field installation improvement and normative adjustments, sketching aims and suggesting best practices for its optimization. Further, it will be described PETROBRAS' systems being in use to provide natural gas flow measurement control and management, from available data in transporters' SCADA system to billing, and to integrate the processes of: shipping scheduling; transmission and delivering; real time supervision; and consolidation of these information for invoicing.

    2004-11-01

    In the last decade hydrocarbon gas geochemistry has significantly evolved especially regarding to the widespread use of GC-C-IRMS (Gas chromatography-combustion-ion ratio monitoring system) techniques that allowed accurate measurements of {delta}{sup 13} C in the C{sub 1}-C{sub 4} fraction. Also, due to the improvement of the sampling procedures, sample collection - relatively small amounts of gas samples at low pressure - has become easier, sample transportation has become safer - the risk of accidents has been reduced - and analysis has become faster. The 'state-of-the-art' of the use of gas geochemistry to study processes within petroleum systems is discussed in this paper. The discussion is mainly focused on the identification of the hydrocarbon gas origin (biogenesis versus thermo genesis, mixing) and hydrocarbon gas generation (primary versus secondary cracking), including the inference of the relative thermal evolution and possible secondary alterations caused by biodegradation, secondary migration and eventually leakage from petroleum accumulations. Brief comments were also made about the new technologies involving noble gases and their potential use as tracers of processes in petroleum systems. Additionally, the origin of non-hydrocarbon gases in petroleum accumulations is succinctly discussed, as well as their possible economic impacts. The use of gas geochemistry techniques has brought a significant improvement in the understanding of petroleum systems under exploration in Brazil and in other parts of the world. Besides, on-going research projects suggest that there is a great potential for technological advances, e.g., adding the hydrogen isotopic composition of hydrocarbons to the interpretations, and also integrating the available results to the isotopic variations of noble gases.

    2016-09-01

    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.

    The consumption of electricity in Brazil and mainly in the State of Sao Paulo is increasing gradually. On the other hand, the hydraulic potential is practically exhausted and the government has no resources for such new investments. One solution is the construction of thermo electrical plants with the use of the natural gas and sugar cane bagasse. The natural gas has the advantage of being available in great amount and less pollutant. And the sugar cane bagasse, besides being a by-product of low value, does not cause a global pollution. The work consists of the determination of the best option considering criterion of minimum cost for kWh of energy produced. For such, thermo economic analysis with electricity and steam production costs evaluation in exergetic basis, was accomplished. In the evaluations the consumption of natural gas and the costs of the sugar cane bagasse were varied. The results show that the cogeneration plant with combined cycle using natural gas and burning sugar cane bagasse in the recovery boiler presents the smallest cost of electricity and steam generation (even not being the cycle with larger exergetic efficiency). On the other hand, for a natural gas cost of 140 US$/t and a cost of sugar cane bagasse superior to 10,50 US$/t the cogeneration plant with combined cycle using only natural gas (and, therefore not burning or gasifying sugar cane bagasse) presented the smallest cost of electricity and steam generation.

    This paper discusses the Conversion Program of Rio de Janeiro city, from Town Gas to Natural Gas, looking for evaluating its logistic and benefits, highlighting mainly those related to consumer's safety. The Conversion Program is been implemented under Companhia Distribuidora de Gas do Rio de Janeiro (CEG) supervision, with support of Rio de Janeiro State University (UERJ) in service's quality appraisal and conversion technical procedure elaboration and review. This partnership has started in 2001 and 46% of all residential and commercial customers have already been converted up to July 2004. Conversion Program is divided into the following Phases: Design and Planning, Gas Distribution Network Renovation and Adaptation, Revision, Post-Revision, Conversion and Post-Conversion. This Program may serve as model for similar programs, to be developed in other cities where Natural Gas will be distributed, displacing the Liquefied Petroleum Gas (LPG), and it is one contribution to achieve the federal governmental goal of 12%-NG-participation within Brazilian Energetic Matrix in 2010.

    Considering the wide increase of natural gas participation in the Brazilian energetic source matrix, this paper describes, comments and analyzes how the natural gas flow measurement process has been structured in PETROBRAS, so that it become a potential factor of this increase. Initially, the work makes a metrological approach of measured volumes, based on volumetric balance of the gas flow in the two principals pipe segments of PETROBRAS gas line network, localized in the Brazilian southeast and northeast systems. This approach runs through the investigation of several parameters that have influence on that balance, considering field installation improvement and normative adjustments, sketching aims and suggesting best practices for its optimization. Further, it will be described PETROBRAS' systems being in use to provide natural gas flow measurement control and management, from available data in transporters' SCADA system to billing, and to integrate the processes of: shipping scheduling; transmission and delivering; real time supervision; and consolidation of these information for invoicing.

    This paper presents a technical, financial and environmental feasibility study, and market analysis, of a 50-TR chiller with vapor compression (mechanical) cycle powered by internal combustion engine. This type of equipment allows natural gas usage for medium-and-low-capacity refrigeration applications, for which there are not competitive commercial equipment based on absorption refrigeration cycle. The technical feasibility is not questionable because it is the association of two remarkably mature technologies and also because such equipment are common in Europe and USA. The natural gas powered equipment operation costs are lower than electricity powered ones, due to lower energy cost, while acquisition, installation and maintenance costs show the opposite. The Net Present Value is positive. The financial feasibility depends directly on the combination of prices of natural gas and electricity, as well as equipment energy efficiencies. The environmental analysis points to the use of electric-driven equipment, which avoids urban area emissions, reinforced by the hydroelectric generation, renewable, used in Brazil. This study had financial support from PETROBRAS/RedeGasEnergia. (author)

    This paper investigates energy resilience of countries by quantifying the supplier diversification of both direct and embodied energy import. In particular, we quantify two approaches to diversify a country's supplier portfolio: by lowering the dependency on each supplier (portfolio diversification) and by having embodied energy suppliers that are different from its direct energy suppliers (portfolio differentiation). We examine possibilities for strategic utilization of embodied energy trade to compensate for low diversity of direct energy trade for three types of fossil resources: coal, oil, and gas. We find that the diversity of embodied energy import is much greater than that of direct energy import. Of the three energy resources, coal enables countries to adopt portfolio diversification and portfolio differentiation more than gas and oil. Our results suggest embodied energy can be considered as a transfer of energy resources across national borders that can directly benefit from the diversity of the world energy production by “skipping” the limited diversity of the world energy export. - Highlights: • We quantify the diversity of countries’ supplier-portfolios of embodied energy. • The diversities of embodied energy import are greater than direct energy import. • Embodied energy is energy transfer that “skips” limited diversity of energy trade.

    The conversion of gasoline to natural gas powered vehicles faces some problems that limit its market expansion, so as the expensive costs inherent to the conversion, low autonomy and the reduction of the available trunk space. Thus, this research focuses on the adsorbed natural gas technology. Therefore three major items were analyzed: several porous materials so as to store the NG in lower pressure, without a drastic diminishing of capacity storage; new reservoir geometries, to optimize the trunk available space and the Brazilian legislation in order to determine the possibility of using cylinders made of alternative materials looking for a weight reduction. From the analysis of the Brazilian standards, we can conclude that there is a need for standardizing the use alternative NGV alternative cylinders, for example, the composite reservoir. The adsorption study over activated carbons resulted in an increased NG storage capacity when compare with compressed gas storage at the same operation conditions, but it is still far from the GNC maximum storage capacity and commercial application. For the reservoir structural modeling, three different geometries were selected and analyzed. (author)

    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

  10. 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

It provides several case studies and some useful links which can serve as a starting point for interested researchers. In the appendix several computer code wri...

  16. Emerging nuclear suppliers in the Third World

    International Nuclear Information System (INIS)

    Stahl, K.

    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

  17. Supplier Evaluation Process by Pairwise Comparisons

    Directory of Open Access Journals (Sweden)

    2015-01-01

    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.

  18. The emerging nuclear suppliers and nonproliferation

    International Nuclear Information System (INIS)

    Potter, W.C.

    1990-01-01

    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

    2001-01-01

    In order to motivate the hundreds of companies building their detectors, the CMS and ATLAS collaborations have recently been handing out awards of excellence to their top suppliers. At its second ceremony of this kind, CMS honoured four of its suppliers, while ATLAS for the first time paid tribute to two of its contractors. The atmosphere in the Council Chamber was festive rather than formal at the start of CMS week on Monday 5 March. Before embarking upon a long series of seminars and presentations, the Collaboration held its second awards ceremony to honour its top suppliers. By paying tribute to the exceptional efforts of certain suppliers, the Collaboration's aim is to motivate all the firms, some 500 in total, taking part in the experiment's construction. The CMS Awards panel thus singles out contractors who have not only provided full satisfaction in terms of compliance with specifications, quality and deadlines, but have in addition provided original solutions to delicate problems. Four firms came away...

    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.

  18. 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.

    Mehdi HakimiAsl

    2016-08-01

    Full Text Available In the previous decade, fossil energy resources shortage and environmental challenges such as air and water pollution, global warming, and greenhouse-gas emissions, etc. have increased environmental concerns considerably. Since, one of the most practical and useful solutions to decrease environmental pollutants is to deploy green purchasing and clean energies by organizations or even governments. Thus, the construction of renewable-energy power plants and, consequently, the green supplier selection for these plants’ equipment has become more important. With this respect, this article presents a novel approach to assess and select green suppliers of a solar power plant. The proposed approach integrates Fuzzy Analytic Hierarchy Process and VIKOR (Vise Kriterijumska Optimizacija I Kompromisno Resenje methodologies. The results demonstrate the efficiency of the proposed approach as a practical tool to assist managers and CEOs (Chief Executive Officers of electric power industry in assessing suppliers of solar power plant’s equipment.

  20. Supplier strategies and responses to institutional drivers for an emerging energy technology

    International Nuclear Information System (INIS)

    Strachan, N.; Dowlatabadi, H.

    2004-01-01

    This paper investigates the role of suppliers of a new energy technology, when the market for that technology continues to be in a state of flux, and is characterised by continued regulatory and institutional developments. This paper first summarises the institutional drivers resulting in the widely divergent diffusion of distributed generation (DG) based on natural gas engines in the Netherlands and the UK. Then, supplier responses to this institutionally driven market are discussed. Under regulatory support, supply firms were able to implement innovative operational and ownership arrangements, hugely growing the market while positioning themselves for new R and D and market developments. Under regulatory restrictions, supply firms fought to survive, with resultant implications for the reputation and longer term prospects for this new energy technology. The paper concludes by discussing how continuing institutional instability can limit the supplier strategies based on spillovers from successful regulatory experiments, Thus, the establishment of a viable energy supply industry is delayed under continuing regulatory uncertainty.

    This paper shows the effects on the gas turbine performance with a washing system out of line, based on liquid detergent and water for the case of 2 Ruston TB5000 gas turbines located in conditions of high contamination in the atmosphere such as ashes, high humidity and temperature. The investigation was realized making periodical measurements of the main parameters of the turbo-pump during 1 year of operation with load conditions without stopping of about 125 mbpd (million of barrels per day) of gas LP. This article suggests how the low performance of the turbines in a hostile atmosphere can be improved and which could be the limitations of the washing systems based on liquid detergents. The data of the washing sessions were collected during a year and studied under statistical methods creating performance curves and comparing them with curves of other machines being washed with other washing systems.

La investigacion fue realizada haciendo mediciones periodicas de los parametros principales de turbo bomba durante 1 ano de operacion con condiciones de carga sin parar de alrededor de 125 mbpd (millones de barriles por dia) de gas LP. Este articulo sugiere como se puede mejorar el bajo desempeno de las turbinas en un ambiente hostil y cuales podrian ser las limitaciones de los sistemas de lavado basados en detergentes liquidos. Los datos de las sesiones de lavado fueron recolectados durante un ano y estudiados bajo metodos estadisticos creando curvas de rendimiento y comparandolas con curvas de otras maquinas siendo lavadas con otros sistemas de lavado.

    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.

    2002-02-01

    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.

  14. 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."

    2017-01-01

    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.

    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.

    Full Text Available Entre los sistemas de refrigeración movidos térmicamente asistidos por energía solar y gas natural, el sistema de refrigeración con eyector ha recibido especial atención. Este sistema se caracteriza por su simplicidad constructiva, ausencia de partes móviles, operación en bajas temperaturas y bajo costo operacional. Sin embargo, el ciclo de refrigeración por eyector tiene usualmente un bajo coeficiente de desempeño. Una alternativa de solución a este problema lo constituye el sistema de refrigeración con eyector combinado. La primera etapa está constituida por un ciclo de compresión mecánica de vapor convencional con R134a, mientras que la segunda etapa la constituye un ciclo termo-movido con eyector usando R141b como fluido de trabajo. Colectores de placa plana y un quemador de energía auxiliar entregan calor al ciclo de eyector. Este artículo describe la simulación en base horaria de un sistema de refrigeración combinado eyector-compresión de vapor asistido por energía solar y gas natural. El sistema de refrigeración solar combinado es modelado usando la herramienta de simulación TRNSYS-EES y los datos climáticos de un año típico de Florianópolis, Brasil. Los resultados obtenidos con la modelación computacional desarrollada para este sistema muestran la ventaja del ciclo de refrigeración combinado eyector-compresión de vapor por sobre el ciclo simple con eyector.

    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.

    This paper presents the development of an integrated simulation model, for the numerical calculation of thermal-hydraulic behaviors in the Brazilian southeast onshore gas pipeline flow system, remotely operated by TRANSPETRO's Gas Pipeline Control Centre (CCG). In its final application, this model is supposed to provide simulated results at the closer range to reality, in order to improve gas pipeline simulation studies and evaluations for the system in question. Considering the fact that numerical thermo-hydraulic simulation becomes the CCG's most important tool to analyze the boundary conditions to adjust the mentioned gas flow system, this paper seeks and takes aim to the optimization of the following prime attributions of a gas pipeline control centre: verification of system behaviors, face to some unit maintenance stop or procedure, programmed or not, or to some new gas outlet or inlet connection to the system; daily operational compatibility analysis between programmed and realized gas volumes; gas technical expedition and delivery analysis. Finally, all this work was idealized and carried out within the one-phase flow domain (dry gas) (author)

  11. 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.

    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.

    2016-01-01

    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.

    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.

    2008-01-01

    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.

    Science.gov (United States)

    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.

    Full Text Available Supplier selection management has been considered as an important subject for industrial organizations. In order to remain on the market, to gain profitability and to retain competitive advantage, business units need to establish an integrated and structured supplier selection system. In addition, environmental protection problems have been big solicitudes for organizations to consider green approach in supplier selection problem. However, finding proper suppliers involves several variables and it is critically a complex process. In this paper, the main attention is focused on finding the right supplier based on fuzzy multi criteria decision making (MCDM process. The weights of criteria are calculated by analytical hierarchical process (AHP and the final ranking is achieved by fuzzy technique for order preference by similarity to an ideal solution (TOPSIS.

    2010-12-01

    Full Text Available This paper presents a multi-criteria decision making model used for supplier selection for software development outsourcing on e-marketplaces. 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.

  19. Consequences of information technology usage on retailer-supplier relations

    DEFF Research Database (Denmark)

    Esbjerg, Lars

    1. Retailers and suppliers increasingly tend to form long-term co-operative relationships. In the literature, the use of information technology is an enabling factor behind this trend. Nevertheless, our understanding of how information technology influences retailer-supplier relationships is still...... limited. The purpose of this paper therefore is to study the consequences of information technology usage on retailer supplier relationships, focusing on inter-organisational systems. 2. The paper begins by discussing the nature of retailer-supplier relations, noting that whereas these relationships have...... traditionally been adversarial, retailers and suppliers are beginning to realise that they can benefit from co-operating. Further, developmental processes in co-operative inter-organisational relations are discussed and the important role of social exchange in inter-organisational relationships is stressed. 3...

  20. Cooperative Evolutionary Game and Applications in Construction Supplier Tendency

    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.

  1. Would you procure radioactive containers without a supplier quality evaluation?

    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.

    2012-10-01

    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.

    Full Text Available This study presents a model for evaluating the carbon and energy management performance of suppliers by using multiple-criteria decision-making (MCDM. 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.

  8. Desktop war - data suppliers competing for bigger market share

    International Nuclear Information System (INIS)

    Sword, M.

    1999-01-01

    The intense competition among suppliers of computerized data and computer software to the petroleum and natural gas industry in western Canada is discussed. It is estimated that the Canadian oil patch spends a large sum, about $ 400 million annually on geoscience information and related costs and industry is looking for ways to significantly reduce those costs. There is a need for integrated, desktop driven data sets. Sensing the determination of industry to reduce information acquisition costs, data providers are responding with major consolidation of data sets. The major evolution in the industry is on-line access to increase the speed of information delivery. Data vendors continue to integrate land, well, log, production and other data sets whether public or proprietary. The result is stronger foundations as platforms for interpretive software. Another development is the rise of the Internet and Intranets and the re-definition of the role of information technology departments in the industry as both of these are paving the way for electronic delivery of information and software tools to the desktop. Development of proprietary data sets, acquisition of competitors with complimentary data sets that enhances products and services are just some of the ways data vendors are using to get a bigger piece of the exploration and development pie

    Juan Manuel Ramón Jerónimo

    2007-12-01

    Full Text Available This paper is focused on the effect that the exchange of management information has on client and/or supplier relationships. Moreover, this study extends the concept of the usefulness of management control information to inter-organizational relationships, analysing how the scope of such information affects continuity expectations, and how these in turn influence opportunistic behaviour and the mutual adaptation of production systems. The data was gathered from 104 purchasing and 90 sales managers of equipment manufacturers on the nature of their respective relationships with their suppliers/ clients. The results confirm that the use of broad-scope management control information sharing in buyer-supplier relationships increases continuity expectations and reduces opportunistic behaviour.El objetivo de este trabajo es analizar el efecto que ejerce el intercambio de información de gestión sobre las relaciones con clientes y/o proveedores. Para ello, se extiende el concepto de la utilidad de información de control de gestión a las relaciones ínter-organizativas, analizando cómo su contenido afecta a las expectativas de continuidad y éstas a su vez influyen en el comportamiento oportunista y en la adaptación mutua de sistemas de producción. Los datos analizados se han obtenido de las relaciones entre 104 directores de compras y 90 directores de ventas de empresas industriales con sus proveedores y clientes. Los resultados confirman que utilizar información compartida de control de gestión con un contenido más amplio en las relaciones compredor/proveedor favorece la creación de expectativas de continuidad y reduce comportamientos oportunistas.

    The UK residential (household) sector is responsible for approximately 30% of total carbon dioxide emissions and is often seen as the most promising in terms of early reductions. As most direct household emissions come from only two fuel sources, this paper critically examines how existing emissions reduction policies for the sector shape - and are shaped by - relations between the three main groups of actor in this policy domain: central government, gas and electricity suppliers, and energy users. Focusing on relations between three dyads (government-suppliers, suppliers-consumers and consumers-government) enables us to examine aspects of demand reduction that have often been overlooked to date. By 'relations' we refer to services, power relationships and flows of capital and information, as well as less easily defined elements such as loyalty, trust and accountability. The paper argues that the chosen government policy path to deliver demand reduction, which heavily emphasises the suppliers' role, suffers from principal-agent problems, fails to align consumers and supplier interests toward emissions reduction, and does not yet portray a lower-carbon future in positive terms. It suggests that more attention should be paid to government-consumer relations, recognising that energy consumers are also citizens. (author)

    2017-02-01

    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.

    logic theory and its performance was evaluated using a non- linear mathematical model that emulates the CTCC behavior. The fuzzy supervision system is integrated by three main modules: Supervision of blades temperature during the starting stage of the UTG; Supervision of blades temperature runback during the power generation stage of the UTG, and Control by Temperature during power generation stage of the UTG. The temperature fuzzy supervisor is implemented in a nonlinear mathematical model that simulates a CTCC. The obtained and analyzed results in the different sceneries of the simulation tests show that the temperature fuzzy supervision system displays a better performance than the obtained with the scheme of conventional supervision. [Spanish] En las Unidades Turbogas (UTG) de una Central Termoelectrica de Ciclo Combinado (CTCC), una de las variables criticas tanto desde el punto de vista operativo como desde el punto de vista de seguridad, es la temperatura de los alabes de la turbina. El mejor desempeno de la unidad turbogas desde el punto de vista de generacion electrica se obtiene cuando es posible lograr la mayor eficiencia termica. Desde el punto de vista de seguridad se busca mantener la temperatura de los alabes en el limite impuesto por el fabricante, garantizando con esto la integridad de las partes internas de la UTG al evitar que esfuerzos termicos considerables decrementen su vida util. Para mantener la temperatura de alabes dentro del limite establecido, el sistema de control de la UTG cuenta con un sistema de supervision de temperatura de alabes, que modifica la referencia de los controladores PI de velocidad o de potencia generada, mismos que regulan la valvula de flujo de combustible a la camara de combustion de la UTG. Este sistema de supervision esta basado en condiciones logicas para generar su salida. En las plantas de proceso cuya operacion es compleja y su comportamiento dinamico es no lineal, las estrategias de control de lazo simple no

    At the present time, the turbo-gas units (TGU) make an important contribution in the development and growth of the national power sector, since this type of units pertaining to the Comision Federal de Electricidad (CFE) contributes with the 6.23% of the national production, that is to say, 2600 MW approx. The turbo-gas units are aero-derivative gas turbines used for power generation, pumping and compression. Generally, they are used to support urgent requests in the demand of electricity or, for the permanent supply of electrical energy in isolated zones. In addition, they are used to quickly get into and get out of operation, which requires high availability, trustworthiness and flexibility. In this sense, and with the intention of improving the operation of the TGUs, the Gerencia de Control e Instrumentation (GCI) (Management of Control and Instrumentation) of the Instituto de Investigaciones Electricas (IIE), has developed a control technology for this type of units, able to replace the original control systems of units with even 30 years of continuous operation or to be installed in new units.

    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

  16. The responsibility of nuclear suppliers in the international market

    International Nuclear Information System (INIS)

    Thiessen, C.W.; Cotton, J.D.; Tait, B.I.

    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.

  17. An examination of hospital satisfaction with blood suppliers.

    Science.gov (United States)

    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.

  18. Preferred supplier contracts in post-patent prescription drug markets.

    Blankart, Carl Rudolf; Stargardt, Tom

    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.

  20. Using MACBETH method for supplier selection in manufacturing environment

    2013-04-01

    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.

  1. Shifting orders among suppliers considering risk, price and transportation cost

    Science.gov (United States)

    Revitasari, C.; Pujawan, I. N.

    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.

    Any design office or company is doubly concerned by the opening to competition of power and gas market since July 1, 2004, because any professional power or gas consumer will become eligible and will have the possibility to select its own energy supplier. Electricite de France (EdF) and Gaz de France (GdF) historical utilities are well-known in France and only few challengers have been identified by non-specialists so far. Also, only EdF and GdF have started since mid-April 2004 a promotion campaign for their commercial offers. This article recalls the regulatory context of the deregulation of gas and electricity markets and its forthcoming consequences on consumers' contracts and energy prices. (J.S.)

    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. The study has shown that the SMEs wereinvolved from the early stages of the product development process that is during the design stage. Theproduct development efforts have shown to contribute towards increasing firms’ market share andfirms were also able to gain a better understanding of future product demand. A significant number ofthe suppliers have managed to penetrate the export market. Unfortunately, among the respondents,there is only one system supplier. This indicates that, either the technological capabilities of theSMEs still needed upgrading for the requirement as

    The natural gas pipeline transport is carried out by one or more compression stations. Each station possesses one or more compressors. The compressor's fuel is usually natural gas itself. The amount of natural gas consumed by the compressors fluctuates daily according to the demand at the city-gates. The daily operational result of a pipeline is known as imbalance. The imbalance is the difference between the natural gas entering into a in a pipeline and the volume delivered in the city-gates added to system use gas. The imbalance analyses in a pipeline that uses natural gas powered compressors requires the analyses of the system use gas. The aim of this work is to study the system use gas in the Bolivia-Brazil pipeline using the available data from the Superintendencia de Comercializacao e Movimentacao de Petroleo, seus Derivados e Gas Natural - ANP and compare the change of the volume consumed before and after the entry into operation of the Campinas-Rio gas pipeline.

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

    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.

    2003-05-01

    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

    In this paper a hybrid solid oxide fuel cell (SOFC) system, applying a combined cycle using gas turbine for rational decentralized energy production is analyzed. The relative concepts about the fuel cell are presented, followed by some chemical and technical information such as the change of Gibbs free energy in isothermal fuel oxidation directly into electricity. This represents a very high fraction of the lower heating value (LHV) of a hydrocarbon fuel. In the next step a methodology for the study of SOFC and gas turbine system is developed, considering the electricity and steam production for a hospital. This methodology is applied to energetic analysis. Natural gas is considered as a fuel. A Sankey Diagram shows that the hybrid SOFC system is a good opportunity to strengthen the decentralized energy production in Brazil. It is necessary to consider that the cogeneration in this version also is a good technical alternative, demanding special methods of design, equipment selection and contractual deals associated to electricity and fuel supply.

    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

    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.

    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.

  11. 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

  13. Suppliers response to liberalization in Europe

    Boon Von Ochssee, T.

    2007-03-01

    Current EU target of achieving a fully liberalized internal market today does not guarantee the availability of volumes tomorrow. Europe will have to compete with other markets, such as the US in the Atlantic Basin and perhaps the Pacific Basin in the future as far as LNG is concerned. Thus, it is against the backdrop of scarcity in a seller's market that Europe's security of supply must be perceived in the period leading up to 2010, 2020 and beyond. Nevertheless, the focus of Europe's energy concerns will lay with internal developments, primarily competition, unbundling and the ostensible development of an increased share of sustainable energy mix by 2020. Whether the European Commission's ultimate goal, a transparent and completely liberalized gas network system, will be supplied with the necessary volumes to sustain demand growth is another matter. This article seeks to shine the limelight on the external aspects of the EU energy dimension.

    In the petroleum industry, the design of multiphase production systems requires an accurate estimation of the gas-oil ratio (GOR) in the transporting pipelines. However, existing GOR estimation methods are often inadequate in terms of desired accuracy and application range, due to the complex phase distributions and the wide range of fluid properties encountered in production operations. In this paper, the effectiveness of using artificial neural networks in determining GOR values is evaluated, proving to be a reasonable way to monitor this property during oil transportation.

    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

    Power systems based on fuel cells have been considered for residential and commercial applications in energy Distributed Generation (DG) market as these systems can minimize their acquisition, installation and operation high costs. In this work we present an experimental analysis of a power generation system formed by a 5 kW proton exchange membrane fuel cell unit and a natural gas reformer (fuel processor) for hydrogen production, of the CEPEL's Fuel Cell Laboratory. It was determined the electrical performance of the cogeneration system in function of the design and operational power plant parameters. Additionally, it was verified the influence of the activation conditions of the fuel cell electrocatalytic system on the system performance. It also appeared that the use of hydrogen produced from the natural gas catalytic reforming provided the system operation in excellent electrothermal stability conditions resulting in increase of the energy conversion efficiency and of the economicity of the cogeneration power plant. The maximum electrical efficiency achieved was around 38% and in all power range unit operated with average potential per single fuel cell higher than 0.60 V. (author)

    Before the beginning of PROALCOOL in 1975, the first effective program in the world using biomass in large scale as an automotive fuel, sugar/alcohol industries already used sugar cane bagasse - a by-product of sugar/alcohol production - to generate energy for sugar production. Currently, besides the fact that they are self-sufficient in thermal/electrical energy, sugar/alcohol industries produce small electricity excess which is exported to local utilities. Gasifier/gas turbine systems are more advanced technologies which are being developed and shall be commercialized in eight to ten years approximately, presenting much higher efficiency, at low cost and inducing more exportable electricity. In this study, possibilities of gasifier/gas turbine systems are evaluated and projections of bagasse based electricity production are presented, until year 2010, for Sao Paulo state and Brazil. Generation costs of gasified bagasse based electricity are calculated: they shall be lower than electricity cost from fossil origin. Influence of electricity sale on the reduction of alcohol production cost are also evaluated for several opportunity costs of bagasse. Environmental and social impacts are analyzed, including evaluation of the cost of avoided carbon, related to the substitution of fossil fuel by sugar cane bagasse in thermoelectric power plants.

    2014-01-01

    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.

    2016-01-01

    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.

    1998-07-01

    The present work analyses some proposals of cogeneration systems for the simultaneous generation of power, heat and refrigeration in a brewery. The requirements of steam, refrigeration and electricity, as well as the production of beer in a plant of the Antarctica Company, located in Jaguariuna - SP were collected monthly for the year of 1997. Three conceptions of systems using two gas turbines with heat recovery steam generator were then proposed to meet the surveyed demand. The proposals differ in the refrigeration system: the first one uses a traditional ammonia compression system while the second uses an ammonia absorption system, the third proposal is a combination of the compression and absorption systems. These proposals are compared to the present configuration which purchases electricity from the Public Utility for power and refrigeration (using an ammonia compression)system, and fuel oil to generate steam for process heat. The technical, economical and environmental feasibility of the proposals, as well as of the present configuration are discussed on the basis of mass balances, energy balances (first law of Thermodynamics), exergy fluxes (second law analysis), operational and capital cost, based on simulation of the performance of each configuration proposed to meet the monthly electricity, steam and refrigeration requirements for the referred plant. The turbines were chosen so as to meet the peek energy demand of the plant and two cases were simulated for each proposal: turbine operational meets only the demand of the plant and turbine operates at full load, selling electricity for the Public utility. Results obtained show that the current operational costs are higher than any of the proposals presented. The high capital costs of the proposals, though,make them less interesting financially. The simulation of the case of excess electricity to the Public Utility is very attractive, considering the cost of natural gas 3,38 U$/M btu and the fare of 40 U

    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.

    2014-06-01

    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.

    Jankovich, J.P.

    1991-01-01

    In this paper the quality assurance inspections of the transportation packaging supplier industry, conducted by the U.S. Nuclear Regulatory Commission (NRC) on a routine basis since 1989 are discussed. The term supplier is used to include designers, fabricators, and distributors that hold NRC approved Quality Assurance Programs and Certificates of Compliance for packagings to transport radioactive materials. The objective of the inspections is to provide assurance that transportation packagings are fabricated and procured in accordance with 10 CFR Parts 21 and 71 requirements. The inspections are conducted in a systematic and comprehensive manner, utilizing uniform inspection techniques in order to assure uniformity and comparability. During the April 1989 and May 1991 period approximately 21 inspections were conducted by the Transportation Branch, Office of Nuclear Material Safety and Safeguards of the NRC. The majority of the findings were identified in the areas of quality assurance procedures, control of special processes (e.g. welding, radiography), and maintenance of QA records

    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

    1990-06-01

    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

  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.

    Yorkshire Electricity, among other independent suppliers of gas, now competes for a share of the United Kingdom gas market, previously monopolised by British Gas. The experience of this successful electric utility company, expanding into the industrial and domestic gas supply market is described in the article. The company`s involvement stems partly from the fact that significant volumes of gas are landed at three terminals within its franchise area. The company will also seek to use subsidaries to generate electric power from gas turbine power plants and explore the possibilities of developing combined heat and power (CHP) plants where appropriate.

  4. Liability of German suppliers and service providers for foreign projects

    International Nuclear Information System (INIS)

    Raetzke, Christian

    2017-01-01

    Main topic is the question of the extent to which German plant constructors, suppliers, engineering consultants, experts or operators expose themselves to liability for the delivery of their products and services abroad. 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.

  5. ATLAS Supplier Award for the ECT Vacuum Vessels

    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...

  6. COLLABORATION BETWEEN SMALL RETAIL STORES AND SUPPLIERS OF FOOD PRODUCTS

    Lenka Branska

    2017-01-01

    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.

    Apesar das pesquisas com sistemas silvipastoris terem sido iniciadas no final da década de 1970, as informações geradas até hoje não são em grande número. As vantagens advindas de um sistema silvipastoril são inúmeras e devidamente reconhecidas. Pelo fato de ser uma técnica de uso da terra capaz de recuperar ecossistemas alterados pelo mau manejo, estes sistemas, pela integração de atividades agrícolas, pecuárias e silviculturais, passam a representar uma tecnologia que confere maior sustentabilidade que os sistemas tradicionais, nos quais os monocultivos são predominantes. Nos últimos anos, instituições de ensino, pesquisa e extensão do País têm se voltado para o desenvolvimento de tais sistemas. O governo de Minas Gerais, por meio de sua Secretaria de Estado de Agricultura e de órgãos vinculados, vem promovendo a condução de modelos agrossilvipastoris num processo integrado de ocupação do solo, denominado lavoura-pecuária-silvicultura. Apesar dos grandes avanços no conhecimento de culturas anuais e dos componentes arbóreos, principalmente o eucalipto, e de gramíneas forrageiras tolerantes à diminuição da intensidade luminosa, ainda é necessário se comnhecer melhor o manejo do sub-bosque sob os efeitos do pastejo.

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

    Directory of Open Access Journals (Sweden)

    Diana Puspita Sari

    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.

    Full Text Available Introduction/Objective. As a risk factor for chronic diseases, metabolic syndrome (MS is increasing at an alarming rate. The prevalence of MS varies according to lifestyle and occupation in different populations. The present study aimed to determine the prevalence of MS and its components in food suppliers. Methods. A total of 112 food suppliers were randomly selected from all around the city. Data collection tools included demographic, physical activity, and food frequency questionnaires. Body composition was measured using Bio-Electrical Body Analyzer. A sample of 5 ml of fasting blood was taken from participants to assess lipid profile, blood sugar, insulin, and liver enzymes. The data were analyzed using χ2, Kolmogorov–Smirnov and ANOVA tests. Results. Participants’ mean BMI was 27.1 ± 3.9 kg/m2, 43.6% were overweight, and 26.4% were obese. Consumption of vegetables was less and of meats more than recommended amounts. The prevalence of MS was 45.5% (51 people, which increased with aging (p = 0.02. Among factors causing MS, the most common one was waist-to-hip ratio (WHR > 0.09 (72.7%, followed by high triglyceride and low HDL. Conclusion. In this study, the prevalence of MS among food suppliers was higher than the world average and than prevalence in other countries. WHR (or obesity was found to be the most important risk factor for MS. To reduce the risk of MS, changing dietary consumption habits and increased physical activity are recommended to persons with high risk and sedentary occupations.

  5. Canada's future role as a propane supplier for the US market

    Energy Technology Data Exchange (ETDEWEB)

    Anderson, A.B.; Zittlau, W.T.

    In Canada, the fall of world crude oil prices that took hold at the beginning of 1986 coincided with the early stages of a long awaited program to dismantle the federal and provincial governments' regulatory framework for the industry. The momentum to deregulate has continued with the industry's support and most recently was manifested by the signing of The Canada-US Free Trade Agreement. Canada has historically been the major supplier of imported propane to the US market. This paper presents one producer and marketer's appraisal of the role Canada is likely to play in meeting US propane shortfalls through the 1990s. Canadian natural gas production will expand considerably during the 1990s to meet a modest expandion of domestic demand and in response to the growing opportunities of the US export market. Current forecasts suggest that gas exports to the US will increase from just under the 1 Tcf level achieved in 1987 to the 1.8 Tcf range by 1995/2000, thus pushing total sales of Canadian gas to 4.3 Tcf by 2000. The other factor to be considered when forecasting propane production from natural gas streams is the liquids content of the gas. Canadian end-use markets for propane are similar to those in the US: residential and commercial space heating, crop drying, specialty industrial applications, transportations and petrochemicals. In addition, over the next five years growing volumes are expected to be used in miscible flood projects. The petrochemical sector accounts for the balance of final consumption of propane in Canada. Based on the foregoing supply/demand analysis the authors see Canadian propane surpluses growing from an estimated 50 thousand b/d achieved in 1987 to nearly 65 thousand b/d in the early 1990s.

  9. 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.

    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)

  16. Production control and supplier selection under demand disruptions

    2010-12-01

    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.

  17. Improving environmental impact and cost assessment for supplier evaluation

    2004-02-01

    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.

    Full Text Available A structured evaluation of the construction industry's suppliers, considering aspects which make their quality and credibility evident, can be a strategic tool to manage this specific supply chain. This study proposes a multi-criteria decision model for suppliers' selection from the construction industry, as well as an efficient evaluation procedure for the selected suppliers. The model is based on SMARTER (Simple Multi-Attribute Rating Technique Exploiting Ranking method and its main contribution is a new approach to structure the process of suppliers' selection, establishing explicit strategic policies on which the company management system relied to make the suppliers selection. This model was applied to a Civil Construction Company in Brazil and the main results demonstrate the efficiency of the proposed model. This study allowed the development of an approach to Construction Industry which was able to provide a better relationship among its managers, suppliers and partners.

    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.

    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

    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)

  12. Natural gas is more than gas power plants

    International Nuclear Information System (INIS)

    Lind, Oddvar

    2000-01-01

    Through the Statpipe gas line at Karmoey, Norway supplies 20% of the natural gas on the European market. The pipeline is 'leaking' a little bit of gas to the local communities at Karmoey and Haugesund. These communities have replaced 65% of their oil consumption with natural gas, which is a fine contribution to a better environment. The supplier of the natural gas, Gasnor ASA in this case, claims an energy efficiency of 90% at the end user because the gas burns directly and the loss in the pipeline is minimal. The efficiency of natural gas utilisation is twice that of the planned gas power stations in West-Norway, subtracting the losses in the electrical network. Gasnor ASA competes with oil suppliers and, if necessary, with electric utilities. The county hospital at Haugesund is quoted as an example. The hospital has two large boilers with dual fuel burners. They have been using natural gas since 1998 because it was worth while both economically and environmentally. The use of natural gas in the transport sector would be very important, but the necessary infrastructure is very little developed. For instance, five diesel-powered ferries on the Boknafjord emit as much NOx as the planned gas power plant at Kaarstoe

    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.

    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.

    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

    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.

  14. 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

    2008-04-01

    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.

    The evaluation, certification, approval and disclosure system of reserves applied in Mexico since 2010 aims to replicate the best practices of the international oil industry. It has gained rigor, simplicity, truthfulness and transparency, however its performance has been unequal: it has achieved to provide more certitude over the proved reserves but it has failed to dissipate the uncertainty over the probable and possible reserves. [Spanish] El sistema de evaluacion, certificacion y aprobacion de reservas aplicado en Mexico desde 2010 busca reproducir las mejores practicas de la industria petrolera internacional.

    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

  1. Suspect/Counterfeit Items Information Guide for Subcontractors/Suppliers

    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

    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.

    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.

  20. 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.

  3. Key Supplier Relationship Management: The Case of Croatian Medium-Sized and Large Manufacturing Companies

    Directory of Open Access Journals (Sweden)

    Dario Miočević

    2011-06-01

    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.

    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.

    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.

    Full Text Available The supplier selection problem represents one of the most important components of the supply chain management. This article presents a multiple criteria decision making analysis contributing to the selection of the most convenient supplier in the flexible packaging industry. 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. According to our extensive experiments, the model developed in this paper is the best model...

    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. This project contributes to the future research on similar topics.

    Full Text Available Selection of one or a combination of the most suitable potential providers and outsourcing problem is the most important strategies in logistics and supply chain management. In this paper, selection of an optimal combination of suppliers in inventory and supply chain management are studied and analyzed via multiple attribute decision making approach, data mining and evolutionary optimization algorithms. For supplier selection in supply chain, hierarchical clustering according to the studied indexes first clusters suppliers. Then, according to its cluster, each supplier is evaluated through Grey Relational Analysis. Then the combination of suppliers’ Pareto optimal rank and costs are obtained using Artificial Bee Colony meta-heuristic algorithm. A case study is conducted for a better description of a new algorithm to select a multiple source of suppliers.

    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.

    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.

  20. Natural gas for utility generation

    Forecasters predict that natural gas will be the dominant fuel choice for utility capacity additions in the coming decade and that power generation will be by far the largest growth market for gas sales. While gas's low emissions, high efficiency potential, and present low cost argue persuasively for a surge in gas-fired generation, many utilities have been slow to commit to a gas future, citing reasoned concern about long-term price trends and the ability of gas suppliers to deliver the fuel where and when it will be needed. Meanwhile, the relatively low cost of gas-fired units is providing an opportunity for independent power producers to compete strongly with utilities for generation contracts. EPRI studies suggest that a sound, competitive strategy will be based not on how much gas a utility burns, but rather on how this capacity fits into its overall generating mix at various fuel price levels. Gas suppliers will need to pay special attention to the operating needs of power generators if they are to solidify this important market
