    Operating room (OR) scheduling information systems can decrease perioperative labor costs. Material management information systems can decrease perioperative inventory costs. We used computer simulation to investigate whether using the OR schedule to trigger purchasing of perioperative supplies is likely to further decrease perioperative inventory costs, as compared with using sophisticated, stand-alone material management inventory control. Although we designed the simulations to favor financially linking the information systems, we found that this strategy would be expected to decrease inventory costs substantively only for items of high price ($1000 each) and volume (>1000 used each year). Because expensive items typically have different models and sizes, each of which is used by a hospital less often than this, for almost all items there will be no benefit to making daily adjustments to the order volume based on booked cases. We conclude that, in a hospital with a sophisticated material management information system, OR managers will probably achieve greater cost reductions from focusing on negotiating less expensive purchase prices for items than on trying to link the OR information system with the hospital's material management information system to achieve just-in-time inventory control. In a hospital with a sophisticated material management information system, operating room managers will probably achieve greater cost reductions from focusing on negotiating less expensive purchase prices for items than on trying to link the operating room information system with the hospital's material management information system to achieve just-in-time inventory control.

    The principles of Just-in-Time inventory management are essentially those of sensible management of productivity and waste. Much of the literature written about JIT, however, is limited in scope in that it focuses on applications in a manufacturing operation. The best way to assess JIT's applicability to all businesses, including hospitals, is to synthesize the characteristics into a basic, conceptual model, which the author does in the following article.

    Just when the power generation industry was stabilizing along came mega government regulations and changing economic conditions that threw a monkey wrench into the works. Although improved inventory practices have helped solve some coal problems, other still remain. The Clean Air Act has resulted in fuel switching, blending, equipment changes, and other factors, all contributing to power plant personnel grey hair. Then along came Just-In-Time inventory practices. Not only is the plant required to make all these changes to meet regulatory requirements, but reduce the quantity of fuel in inventory to unheard of low levels. Why is it so difficult to precisely account for coal in inventory? After all, inventory is a simple matter of accurately measuring the coal coming in to the plant, measuring the coal used by the plant, and conducting an accurate physical inventory to measure the remaining coal. Add to this, a major coal inventory reduction policy, when base maps are not maintained or updated and are, therefore, not likely to be accurate. Some coal may have been stored below the prevailing water table, rendering the coal unusable. Weather conditions, such as major ice storms can render much of the coal unburnable. Unless accounted for, these things reduce the perceived amount of coal in inventory. This presentation will address these issues to assist in preventing potential unscheduled plant shut down and the need to purchase unscheduled blocks of emergency power. Just-In-Time Inventory isn`t as straightforward as first meets the eye.

    Full Text Available Just-In-Time (JIT has been playing an important role in supply chain environments. Countless firms have been applying JIT in production to gain and maintain a competitive advantage. This study introduces an innovative model which integrates inventory and quality assurance in a JIT supply chain. This approach assumes that manufacturing will produce some defective items and those products will not influence the buyer’s purchase policy. The vendor absorbs all the inspection costs. Using a function to compute the expected amount of total cost every year will minimize the total cost and the nonconforming fraction. Finally, a numerical example further confirms this model.

    In recent years, inventory management is continuous challenge for all organizations not only due to heavy cost associated with inventory holding, but also it has a great deal to do with the organizations production process. Cement industry is a growing sector of Pakistan's economy which is now facing problems in capacity utilization of their plants. This study attempts to identify the key strategies for successful implementation of just-in-time (JIT) management philosophy on the cement industry of Pakistan. The study uses survey responses from four hundred operations' managers of cement industry in order to know about the advantages and benefits that cement industry have experienced by Just in time (JIT) adoption. The results show that implementing the quality, product design, inventory management, supply chain and production plans embodied through the JIT philosophy which infect enhances cement industry competitiveness in Pakistan. JIT implementation increases performance by lower level of inventory, reduced operations & inventory costs was reduced eliminates wastage from the processes and reduced unnecessary production which is a big challenge for the manufacturer who are trying to maintain the continuous flow processes. JIT implementation is a vital manufacturing strategy that reaches capacity utilization and minimizes the rate of defect in continuous flow processes. The study emphasize the need for top management commitment in order to incorporate the necessary changes that need to take place in cement industry so that JIT implementation can take place in an effective manner.

    During the 1950s, the Japanese recognized that they would have to upgrade their manufacturing operations significantly if they were going to make inroads into world markets. One of the targets they set for themselves was to eliminate waste, particularly, excess inventory. The Toyota Company originated a concept called kanban hoshiki, which, when translated, means "card system". The name refers to the use of tags (cards) to track the flow of work-in-progress inventory. On this side of the Pacific, the kanban hoshiki inventory management system has been renamed Just-in-Time. The basic premise of JIT is that inventory is an evil presence that drains company cash flow, contributes to wast and misuse of company assets, takes up valuable space, and undermines company profitability. The principal goal of JIT, then, is to get as close to zero inventory as possible. JIT has been applied with success in large manufacturing industries and recently has found a home in small business as well. A growing number of hospitals are also experimenting with the JIT concept, sometimes under the name of stockless purchasing.

    Full Text Available Many companies experience difficulty in implementing Just-in-Time (JIT in their manufacturing system. Based on observations, the article argues that the problem is partly due to confusion about JIT and its implications and partly due to a desire to implement JIT within an existing organisational structure. A four-level classification system is presented as a way of summarising the different degrees of JIT implementation and their difficulties.JIT philosophy has been of great interest to the manufacturers and researchers over the past few decades. JIT systems are designed to produce the goods & deliver services as and when required.JIT systems are capable to attain the far-reaching productivity and quality standards. Numerous benefits have been claimed by the firms implementing JIT across the World. Efforts are being made day-by-day to look into the benefits and their feasibility in the Manufacturing Industries. Despite the profound interest in it, the extent of implementation in India has not been satisfactory. Many firms which had benefitted from JIT systems appear to address only a few features, rather than looking into the whole philosophy of JIT. The paper attempts to address the necessary initiatives required to be taken by the Management of Indian Manufacturing Industry for the implementation of the various JIT subsets, through a survey based on previous literature. Further, it analyzes and concludes the modification of procedures and operations required for its successful implementation along with the challenges encountered during the JIT philosophy implementation.

    Science.gov (United States)

    Singh, D. K.; Singh, Satyendra

    2012-03-01

    Investment in inventory absorbs a large portion of the working capital of a company and often it represents a large portion of the total assets of a business. By improving return on investment by increasing the rate of inventory turnover, management often wants to ensure economic efficiency. Effective inventory management enables a firm to provide lower costs, rapid response and flexibility for its customers. Just-in-time (JIT) philosophy is most widely adopted and practices in the recent years worldwide. It aims at reducing total production costs by producing only what is immediately needed and eliminates wastes. It is based on a radically different concept, deviating substantially from the existing manufacturing practices in many respects. It is a very effective tool to reduce the wastage of inventory and manage it effectively. It has the potential to bring substantial changes in the existing setup of a company; can give it a new face, broaden its acceptability and ensure a longer life. It can strategically change the atmosphere needed for longer survival. JIT is radically different from MRP and goes beyond materials management. The new outlook acquired by the company can meet global expectations of the cust

    Vendor-managed inventory (VMI) represents the methodology through which the upstream stage of a supply chain (vendor) takes responsibility for managing the inventories at the downstream stage (customer) based on previously agreed limits. VMI is another method by which supply chains can be managed......, and, owing to centralised decision-making and constant information sharing, the benefits are much higher than in traditional supply chain case. However, there exists a lack of research that identifies the dimensions of VMI, benefits of VMI, methods, and levels used in the VMI environment. The focus...... of this paper is to explore the existing literature on VMI, to categorise it according to the criteria evaluated, and to present a systematic review. In this study, we have classified the review into three categories such as dimension-based, methodology-based, and level-based. From the thorough literature...

    Biomechanics education is a vital component of kinesiology, sports medicine, and physical education, as well as for many biomedical engineering and bioengineering undergraduate programmes. Little research exists regarding effective teaching strategies for biomechanics. However, prior work suggests that student learning in undergraduate physics courses has been aided by using the Just-in-Time Teaching (JiTT). As physics understanding plays a role in biomechanics understanding, the purpose of study was to evaluate the use of a JiTT framework in an undergraduate biomechanics course. This two-year action-based research study evaluated three JiTT frameworks: (1) no JiTT; (2) mathematics-based JiTT; and (3) concept-based JiTT. A pre- and post-course assessment of student learning used the biomechanics concept inventory and a biomechanics concept map. A general linear model assessed differences between the course assessments by JiTT framework in order to evaluate learning and teaching effectiveness. The results indicated significantly higher learning gains and better conceptual understanding in a concept-based JiTT course, relative to a mathematics-based JiTT or no JiTT course structure. These results suggest that a course structure involving concept-based questions using a JiTT strategy may be an effective method for engaging undergraduate students and promoting learning in biomechanics courses.

  5. Just in Time DSA the Hanford Nuclear Safety Basis Strategy

    The U.S. Department of Energy, Richland Operations Office (RL) is responsible for 30 hazard category 2 and 3 nuclear facilities that are operated by its prime contractors, Fluor Hanford, Incorporated (FHI), Bechtel Hanford, Incorporated (BHI) and Pacific Northwest National Laboratory (PNNL). The publication of Title 10, Code of Federal Regulations, Part 830, Subpart B, Safely Basis Requirements (the Rule) in January 2001 requires that the Documented Safety Analyses (DSA) for these facilities be reviewed against the requirements of the Rule. Those DSAs that do not meet the requirements must either be upgraded to satisfy the Rule, or an exemption must be obtained. RL and its prime contractors have developed a Nuclear Safety Strategy that provides a comprehensive approach for supporting RL's efforts to meet its long-term objectives for hazard category 2 and 3 facilities while also meeting the requirements of the Rule. This approach will result in a reduction of the total number of safety basis documents that must be developed and maintained to support the remaining mission and closure of the Hanford Site and ensure that the documentation that must be developed will support: Compliance with the Rule; A ''Just-In-Time'' approach to development of Rule-compliant safety bases supported by temporary exemptions; and Consolidation of safety basis documents that support multiple facilities with a common mission (e.g. decontamination, decommissioning and demolition [DD&D], waste management, surveillance and maintenance). This strategy provides a clear path to transition the safety bases for the various Hanford facilities from support of operation and stabilization missions through DD&D to accelerate closure. This ''Just-In-Time'' Strategy can also be tailored for other DOE Sites, creating the potential for large cost savings and schedule reductions throughout the DOE complex.

    The scientific method is a system for acquiring knowledge based on the collection of data through observation, experimentation and the integration of previous knowledge. This is followed by the formulation and testing of hypotheses resulting in new knowledge and possibly the correction previous knowledge. From a system design perspective the scientific method is a well defined system, use cases are abundant, requirements are readily accessible and guiding principles are fully articulated. With advancement of technology new implementations emerge to support and enable science. We are now in the age of Virtual Observatories where distributed data are coupled through services and well-defined metadata. The paradigm is one in which information is sought and retrieved just in time for its use. We discuss a system model for a Just In Time Information (JITI) system that addresses the clearly identified needs of scientists. It includes tasks such as coordinate system conversion, file format transformation, subsetting, aggregation, and rendering. We also discuss the discovery needs of the scientist which range from the initial discovery of available resources to complex scientific queries. Overall the system is composed of a collection of small services which are tied together on a task-by-task basis, similar to that of a workflow, but with distributed and loosely coupled components. In a JITI system each service is invoked as needed with unique resource identifiers passed as the common reference thread that enables the service integration. The services that are part of a JITI system can be utilized in a number of ways to implement portals, search engines, aggregators, and mash-ups. JITI-like systems are emerging in the Virtual Observatory communities. We look at NASA's Virtual Magnetospheric Observatory, the Heliophysics Event List Manager (HELM), Europe's HELIO project and Canada's CSSDP project as examples.

    The four functions of management--planning, organizing, directing, and controlling--are described in relation to the hospital pharmacy inventory control system. Planning includes the development of inventory system objectives and identification of the resources needed to complete them. Organizing requires the manager to decide on the best method of grouping system activities and resources to complete the objectives in order of priority. Directing is a continual activity that involves obtaining optimal performance from the inventory system resources available. Controlling consists of regulation and verification of inventory system activities. The effective inventory system manager integrates planning, organizing, directing, and controlling in a continuous cycle.

    The basic financial purpose of a firm is to maximize its value. An inventory management system should also contribute to realization of this basic aim. Many current asset management models currently found in financial management literature were constructed with the assumption of book profit maximization as basic aim. However these models could lack what relates to another aim, i.e., maximization of enterprise value. This article presents a modified value-based inventory management model.

    Ensuring adequate stocks of wound care supplies at wound care to be tied up, and too little can cause problems for patients. Most facilities maintain a "par" level for each item, which requires that supplies be ordered even if the "par" is numerically short by one item. In addition, due to the current just-in-time environment, if attention is not paid to the par level, unexpected shortages of supplies can develop. By using Inventory Trak software developed by Intellicure, facility managers will always know how much stock is presentfor each item, as individual item barcodes are registered in the system each time an item is used through software-linking scanners. The result is increased efficiency, reduced cost to the facility, and an assurance that the facility will not run out of critical items.

    Transportation and disposal of wastes generated by Department of Energy (DOE) activities, including weapons production and decontamination and decommissioning (D&D) of facilities, require that wastes be certified as complying with various regulations and requirements. These certification requirements are typically summarized by disposal sites in their specific waste acceptance criteria. Although a large volume of DOE wastes have been generated by past activities and are presently in storage awaiting disposal, a significant volume of DOE wastes, particularly from D&D projects. have not yet been generated. To prepare DOE-generated wastes for disposal in an efficient manner. it is suggested that a program of just-in-time characterization and certification be adopted. The goal of just-in-time characterization and certification, which is based on the just-in-time manufacturing process, is to streamline the certification process by eliminating redundant layers of oversight and establishing pro-active waste management controls. Just-in-time characterization and certification would rely on a waste management system in which wastes are characterized at the point of generation, precertified as they are generated (i.e., without iterative inspections and tests subsequent to generation and storage), and certified at the point of shipment, ideally the loading dock of the building from which the wastes are generated. Waste storage would be limited to accumulating containers for cost-efficient transportation.

    Full Text Available This study explores the relationship between just-in-time technique and manufacturing performance of some selected Nigerian companies. Just-in time was considered to be an overall organisational phenomenon. Data were obtained through a structured questionnaire from a sample size of 300 knowledgeable employees to test the developed model and formulated hypotheses that cover both just-intime and the supporting infrastructures. Bivariate correlation analysis was used to test the three hypotheses. The results showed that: (1 there was a significant relationship between total quality management (supporting infrastructure and just-in-time practices; (2 Human resources management (supporting infrastructure was positively related to just-in-time practices; (3 there was a positive significant relationship between Just-in-time practices and manufacturing performance. These results demonstrate that justin- time practices can be successfully implemented if certain supporting infrastructures are provided, and also support the notion that just-in-time should be practiced at all levels and departments of the organisation, rather than viewing it strictly for shop floor workers.

    The IDEAL trial shows that the decision to start renal replacement treatment should not depend on GFR alone, but should be taken on the basis of clinical parameters. Quality of Life (QoL) questionnaires and bio-impedance analysis are potential tools for detecting subtle changes in the predialysis clinic. Too early an initiation of dialysis may be deleterious for the patient and the healthcare system. We are convinced that ESRD patients should be informed about intensive haemodialysis (HD), especially nocturnal (home) HD, as the best available dialysis modality. There is substantial evidence which shows that intensive HD improves clinical, biochemical and biological parameters, and may even prolong survival. We believe that 'just-in-time delivery of intensive haemodialysis' may result in optimised QoL and reduced economic burden.

    Early Java implementations relied on interpretation, leading to poor performance compared to compiled programs. Java just-in-time (JIT) compiler can compile Java programs at runtime, so it not only improves Java's performance prominently, but also preserves Java's portability. In this paper the design and implementing techniques of Java JIT compiler based on Chinese open system are discussed in detail. To enhance the portability, a translating method which combines the static simulating method and macro expansion method is adopted. The optimization technique for JIT compiler is also discussed and a way to evaluate the hotspots in Java programs is presented. Experiments have been conducted to verify JIT compilation technique as an efficient way to accelerate Java.

    2008-01-01

    The scale of large neuronal network simulations is memory-limited due to the need to store connectivity information: connectivity storage grows as the square of neuron number up to anatomically-relevant limits. Using the NEURON simulator as a discrete-event simulator (no integration), we explored the consequences of avoiding the space costs of connectivity through regenerating connectivity parameters when needed – just-in-time after a presynaptic cell fires. We explored various strategies for automated generation of one or more of the basic static connectivity parameters: delays, postsynaptic cell identities and weights, as well as run-time connectivity state: the event queue. Comparison of the JitCon implementation to NEURON’s standard NetCon connectivity method showed substantial space savings, with associated run-time penalty. Although JitCon saved space by eliminating connectivity parameters, larger simulations were still memory-limited due to growth of the synaptic event queue. We therefore designed a JitEvent algorithm that only added items to the queue when required: instead of alerting multiple postsynaptic cells, a spiking presynaptic cell posted a callback event at the shortest synaptic delay time. At the time of the callback, this same presynaptic cell directly notified the first postsynaptic cell and generated another self-callback for the next delay time. The JitEvent implementation yielded substantial additional time and space savings. We conclude that just-in-time strategies are necessary for very large network simulations but that a variety of alternative strategies should be considered whose optimality will depend on the characteristics of the simulation to be run.

    Full Text Available Distribution process of a supply chain management is very important and strategic. To stay efficient in delivering the finished goods in the hands of end user, the speed and responsiveness of distribution mechanism are most essential. Just in Time (JIT has proved result oriented in the manufacturing systems since 1985. Since then its applicability in several fields are being investigated. Low inventory, small lot size, least lead time and quality product are some desirable features of JIT, which proves beneficiary to the firm. This paper highlights JIT applied distribution process in order to shorten the lead time, inventory holding costs. Application of Graph theory (GTA methodology has been used to investigate the interdependencies of dimensions and its attributes of JIT implemented distribution. Then an empirical value of JIT distribution process (JDP of an organisation has been derived , subsequently coefficient of distribution dissimilarity and similarity have been found for two organisation and based on these values comparison 0f any two organisation can be done. Approach can be used to know the lacks of various organizations based on their feasibility index of transition (FIT value and which is required to develop to transform the organisation applying JIT in distribution process.

  17. Just In-Time Maintenance of Nuclear Power Plants

    Energy Technology Data Exchange (ETDEWEB)

    DR. Alexander G. Parlos

    2002-01-22

    The goal of this project has been to develop and demonstrate the feasibility of a new technology for maintenance engineering: a Just-In-Time Maintenance (JITM) system for rotating machines. The JITM system is based on several key developments at Texas A and M over the past ten years in emerging intelligent information technologies, which if integrated into a single system could provide a revolutionary approach in the way maintenance is performed. Rotating machines, such as induction motors, range from a few horse power (hp) to several thousand hp in size, and they are widely used in nuclear power plants and in other industries. Forced outages caused by induction motor failures are the reason for as much as 15% - 40% of production costs to be attributable to maintenance, whereas plant shutdowns caused by induction motor failures result in daily financial losses to the utility and process industries of $1 M or more. The basic components of the JITM system are the available machine sensors, that is electric current sensors and accelerometers, and the computational algorithms used in the analysis and interpretation of the occurring incipient failures. The JITM system can reduce the costs attributable to maintenance by about 40% and it can lower the maintenance budgets of power and process plants by about 35%, while requiring no additional sensor installation. As a result, the JITM system can improve the competitiveness of US nuclear utilities at minimal additional cost.

  18. Just in Time in Space or Space Based JIT

    Science.gov (United States)

    VanOrsdel, Kathleen G.

    1995-01-01

    Our satellite systems are mega-buck items. In today's cost conscious world, we need to reduce the overall costs of satellites if our space program is to survive. One way to accomplish this would be through on-orbit maintenance of parts on the orbiting craft. In order to accomplish maintenance at a low cost I advance the hypothesis of having parts and pieces (spares) waiting. Waiting in the sense of having something when you need it, or just-in-time. The JIT concept can actually be applied to space processes. Its definition has to be changed just enough to encompass the needs of space. Our space engineers tell us which parts and pieces the satellite systems might be needing once in orbit. These items are stored in space for the time of need and can be ready when they are needed -- or Space Based JIT. When a system has a problem, the repair facility is near by and through human or robotics intervention, it can be brought back into service. Through a JIT process, overall system costs could be reduced as standardization of parts is built into satellite systems to facilitate reduced numbers of parts being stored. Launch costs will be contained as fewer spare pieces need to be included in the launch vehicle and the space program will continue to thrive even in this era of reduced budgets. The concept of using an orbiting parts servicer and human or robotics maintenance/repair capabilities would extend satellite life-cycle and reduce system replacement launches. Reductions of this nature throughout the satellite program result in cost savings.

    This paper considers the experiences of people with lupus in comparison with those with diabetes, and discusses the impact of lupus specialist nurses in information-giving and education under the guise of 'just in case' vs. 'just in time'. Now recognized as a difficult condition to diagnose, lupus can lead to significant worry and distress especially during delays to diagnosis and times of high disease activity. Providing appropriate, individualized information to people with lupus is embedded in specialist nursing practice and enables individuals to use the tools of self-management approaches in gaining control over everyday symptoms.

    Bandera, Cesar; Marsico, Michael

    2005-05-01

    The diversity of first responders and of asymmetric threats precludes the effectiveness of any single training syllabus. Just-in-time training (JITT) addresses this variability, but requires training content to be quickly tailored to the subject (the threat), the learner (the responder), and the infrastructure (the C2 chain from DHS to the responder"s equipment). We present a distributed system for personalized just-in-time training of first responders. The authoring and delivery of interactive rich media and simulations, and the integration of JITT with C2 centers, are demonstrated. Live and archived video, imagery, 2-D and 3-D models, and simulations are autonomously (1) aggregated from object-oriented databases into SCORM-compliant objects, (2) tailored to the individual learner"s training history, preferences, connectivity and computing platform (from workstations to wireless PDAs), (3) conveyed as secure and reliable MPEG-4 compliant streams with data rights management, and (4) rendered as interactive high-definition rich media that promotes knowledge retention and the refinement of learner skills without the need of special hardware. We review the object-oriented implications of SCORM and the higher level profiles of the MPEG-4 standard, and show how JITT can be integrated into - and improve the ROI of - existing training infrastructures, including COTS content authoring tools, LMS/CMS, man-in-the-loop simulators, and legacy content. Lastly, we compare the audiovisual quality of different streaming platforms under varying connectivity conditions.

  4. Just-in-time: maximizing its success potential.

    Science.gov (United States)

    Johnston, S K

    1990-08-01

    The effective implementation and use of JIT manufacturing practices depends largely on the education, training, and commitment of all levels of management to a fundamental quality-first policy. Management must transfer and demonstrate that commitment to every level and extension of the manufacturing endeavor. As a company establishes and reaches toward that goal, the move to JIT manufacturing practices becomes rational and justifiable. Failing to establish and commit to a quality directive greatly diminishes the potential benefits of JIT. If all levels of manufacturing participate in the JIT planning, implementing, and maintenance procedure, the realization of positive change and improvement drives the process. Total participation makes the task of JIT implementation not only possible, but practical. Enhanced mutual respect for all concerned is a likely consequence, advancing the productive environment.

    Scanlin, T

    1997-10-01

    When people complain about the escalating cost of health care, malpractice suits are often blamed. But the reality is that hospitals' biggest problem may lie in the storeroom, rather than the courtroom. According to a recent study, hospitals spend about $83 billion per year on supplies--$11 billion of which could be reduced through more efficient supply chain practices. In fact, one leading consultant was recently quoted as saying the supply chain may be the number one area where hospitals can reduce cost. While these statements may be ambitious, the sad truth is that the healthcare industry has been slower than others to adopt money-saving logistics practices like just-in-time (JIT) and continuous replenishment, as well as supporting technology like bar coding and radio frequency. As a result, it has been missing out on some significant cost advantages. This article takes a look at how St. Luke's-Roosevelt Hospital Center in New York City implemented a customized JIT inventory system, saving more than $3 million per year.

  10. Just in Time DSA-The Hanford Nuclear Safety Basis Strategy

    Energy Technology Data Exchange (ETDEWEB)

    Olinger, S. J.; Buhl, A. R.

    2002-02-26

    The U.S. Department of Energy, Richland Operations Office (RL) is responsible for 30 hazard category 2 and 3 nuclear facilities that are operated by its prime contractors, Fluor Hanford Incorporated (FHI), Bechtel Hanford, Incorporated (BHI) and Pacific Northwest National Laboratory (PNNL). The publication of Title 10, Code of Federal Regulations, Part 830, Subpart B, Safety Basis Requirements (the Rule) in January 2001 imposed the requirement that the Documented Safety Analyses (DSA) for these facilities be reviewed against the requirements of the Rule. Those DSA that do not meet the requirements must either be upgraded to satisfy the Rule, or an exemption must be obtained. RL and its prime contractors have developed a Nuclear Safety Strategy that provides a comprehensive approach for supporting RL's efforts to meet its long term objectives for hazard category 2 and 3 facilities while also meeting the requirements of the Rule. This approach will result in a reduction of the total number of safety basis documents that must be developed and maintained to support the remaining mission and closure of the Hanford Site and ensure that the documentation that must be developed will support: compliance with the Rule; a ''Just-In-Time'' approach to development of Rule-compliant safety bases supported by temporary exemptions; and consolidation of safety basis documents that support multiple facilities with a common mission (e.g. decontamination, decommissioning and demolition [DD&D], waste management, surveillance and maintenance). This strategy provides a clear path to transition the safety bases for the various Hanford facilities from support of operation and stabilization missions through DD&D to accelerate closure. This ''Just-In-Time'' Strategy can also be tailored for other DOE Sites, creating the potential for large cost savings and schedule reductions throughout the DOE complex.

    To help assure mission success for long-duration exploration activities, NASA is actively pursuing wireless technologies that promote situational awareness and autonomy. Wireless technologies are typically extensible, offer freedom from wire tethers, readily support redundancy, offer potential for decreased wire weight, and can represent dissimilar implementation for increased reliability. In addition, wireless technologies can enable additional situational awareness that otherwise would be infeasible. For example, addition of wired sensors, the need for which might not have been apparent at the outset of a program, night be extremely costly due in part to the necessary routing of cables through the vehicle. RFID, or radio frequency identification, is a wireless technology with the potential for significant savings and increased reliability and safety in space operations. Perhaps the most obvious savings relate to the application of inventory management. A fully automated inventory management system is highly desirable for long-term sustaining operations in space environments. This assertion is evidenced by inventory activities on the International Space Station, which represents the most extensive inventory tracking experience base in the history of space operations. In the short tern, handheld RFID readers offer substantial savings owing to reduced crew time for inventory audits. Over the long term, a combination of improved RFID technology and operational concepts modified to fully utilize the technology should result in space based inventory management that is highly reliable and requires very little crew time. In addition to inventory management, RFID is likely to find space applications in real-time location and tracking systems. These could vary from coarse-resolution RFID portals to the high resolution afforded by ultra-wideband (UWB) RFID. Longer range RFID technologies that leverage passive surface acoustic wave (SAW) devices are being investigated to

    2006-05-01

    Skilled Support Personnel (SSP) serve emergency response organizations during an emergency incident, and include laborers, operating engineers, carpenters, ironworkers, sanitation workers and utility workers. SSP called to an emergency incident rarely have recent detailed training on the chemical, biological, radiological, nuclear and/or explosives (CBRNE) agents or the personal protection equipment (PPE) relevant to the incident. This increases personal risk to the SSP and mission risk at the incident site. Training for SSP has been identified as a critical need by the National Institute for Environmental Health Sciences, Worker Education and Training Program. We present a system being developed to address this SSP training shortfall by exploiting a new training paradigm called just-in-time training (JITT) made possible by advances in distance learning and cellular telephony. In addition to the current conventional training at regularly scheduled instructional events, SSP called to an emergency incident will have secure access to short (graphics, animation, and assessment designed for the user interface of most current cell phones. Engineering challenges include compatibility with current cell phone technologies and wireless service providers, integration with the incident management system, and SCORM compliance.

    Full Text Available Just in time is one of the most important components of having efficient production plan. The primary objective of JIT is to reduce the amount of storage as much as possible to remove the cost of inventories and work-in-progress. However, the implementation of JIT is a tedious task especially in developing countries, where there are shortages for essential infrastructures and increase the risk of production in case of JIT adaptation. In this paper, we present a survey to detect important factors preventing JIT implementation in Iran. The proposed study designs a questionnaire for assessing important factors influencing JIT adaptation, which includes inflation, political sanction, unreliable suppliers, shortage of cash flow and weak organizational culture. The results of our survey confirm that shortage of cash flow is the most important factor, follows by economical sanction and inflation.

  20. Just-in-Time Teaching in undergraduate physics courses: Implementation, learning, and perceptions

    Science.gov (United States)

    Dwyer, Jessica Hewitt

    Regardless of discipline, a decades-long battle has ensued within nearly every classroom in higher education: instructors getting students to come to class prepared to learn. In response to this clash between teacher expectations and frequent student neglect, a group of four physics education researchers developed a reformed instructional strategy called Just-in-Time Teaching (JiTT). This dissertation investigates the following three areas: 1) the fidelity with which undergraduate physics instructors implement JiTT, 2) whether student performance predicts student perception of their instructor's fidelity of JiTT implementation, and 3) whether student perception of their instructor's fidelity of JiTT implementation correlates with student views of their physics course. A blend of quantitative data (e.g., students grades, inventory scores, and questionnaire responses) are integrated with qualitative data (e.g., individual faculty interviews, student focus group discussions, and classroom observations). This study revealed no statistically significant relationship between instructors who spent time on a predefined JiTT critical component and their designation as a JiTT user or non-user. While JiTT users implemented the pedagogy in accordance with the creators' intended ideal vision, many also had trouble reconciling personal concerns about their role as a JiTT adopter and the anticipated demand of the innovation. I recommend that this population of faculty members can serve as a JiTT model for other courses, disciplines, and/or institutions. Student performance was not a predictor of student perception instructor fidelity of JiTT implementation. Additionally, the majority of students in this study reported they read their textbook prior to class and that JiTT assignments helped them prepare for in-class learning. I found evidence that exposure to the JiTT strategy may correlate with a more favorable student view of their physics course. Finally, according to students

    2006-01-01

    Full Text Available The advent of widespread distributed computing environment, such as information systems and computational grids computing has enabled a new generation of applications that are based on seamless access, aggregation and interaction. The dramatic side of the story is a strong presence of the plea that those decentralized Grids are potentially affected by a number of primitives derived from their anatomy, in that, they are inherently large, complex, heterogeneous and dynamic, globally aggregating a large number of independent computing and communication resources. This has clearly exposed an essential exigency for a vital change to how these applications are developed and managed, which has motivated researchers to consider other techniques used by biological systems to deal with such problems. This is referred to as autonomic computing, which is defined by Ganek and Corbi[1] “… as a collection and integration of technologies that enable the creation of an information technology computing infrastructure for the next era of computing—e-business on demand …”. This study presents a computational model to support just-in-time and on-demand services for autonomic computing. Service reservation and job schedule systems are employed in this model to estimate the required services in advanced. Intelligent classification is utilized to cluster consumers into groups sharing the same behaviour and hence offer the required services for each consumer in advance, according to the group’s usage pattern of application services. To this end, a machine learning middleware service based on Self-Organizing Maps (SOM is designed, developed and implemented to carry out the intelligent classification for the autonomic computing. A case-study scenario of intelligent connected homes is demonstrated in this study to show the usability of such system.

    Clinical guidelines and policies are widely available on the hospital intranet or from the internet, but can be difficult to access at the required time and place. Clinical staff with smartphones could use Quick Response (QR) codes for contemporaneous access to relevant information to support the Just in Time Learning (JIT-L) paradigm. There are several studies that advocate the use of smartphones to enhance learning amongst medical students and junior doctors in UK. However, these participants are already technologically orientated. There are limited studies that explore the use of smartphones in nursing practice. QR Codes were generated for each topic and positioned at relevant locations on a medical ward. Support and training were provided for staff. Website analytics and semi-structured interviews were performed to evaluate the efficacy, acceptability and feasibility of using QR codes to facilitate Just in Time learning. Use was intermittently high but not sustained. Thematic analysis of interviews revealed a positive assessment of the Just in Time learning paradigm and context-sensitive clinical information. However, there were notable barriers to acceptance, including usability of QR codes and appropriateness of smartphone use in a clinical environment. The use of Just in Time learning for education and reference may be beneficial to healthcare professionals. However, alternative methods of access for less technologically literate users and a change in culture of mobile device use in clinical areas may be needed.

    Pyarali, Maisam

    2017-01-01

    The LHC is a 26.7 km circumference ring lined with superconducting magnets that operate at 1.9 K. These magnets are used to control the trajectory of beams of protons traveling in opposite directions and collide them at various experimental sites across the LHC where their debris is analyzed. The focus of this paper is the cryogenic system that allows the magnets to operate in their superconducting states. It aims to highlight the operating principles of helium refrigeration and liquefaction, with and without nitrogen pre-cooling; discuss the various refrigerators and liquefiers used at CERN for both LHC and Non-LHC applications, with their liquefaction capacities and purposes; and finally to deliberate the management of the LHC inventory and how it contributes to the strategic decision CERN makes regarding the inventory management during the Year-End Technical Stop (YETS), Extended Year-End Technical Stop (EYETS) and long shutdowns.

  1. Software for Managing Inventory of Flight Hardware

    Science.gov (United States)

    Salisbury, John; Savage, Scott; Thomas, Shirman

    2003-01-01

    The Flight Hardware Support Request System (FHSRS) is a computer program that relieves engineers at Marshall Space Flight Center (MSFC) of most of the non-engineering administrative burden of managing an inventory of flight hardware. The FHSRS can also be adapted to perform similar functions for other organizations. The FHSRS affords a combination of capabilities, including those formerly provided by three separate programs in purchasing, inventorying, and inspecting hardware. The FHSRS provides a Web-based interface with a server computer that supports a relational database of inventory; electronic routing of requests and approvals; and electronic documentation from initial request through implementation of quality criteria, acquisition, receipt, inspection, storage, and final issue of flight materials and components. The database lists both hardware acquired for current projects and residual hardware from previous projects. The increased visibility of residual flight components provided by the FHSRS has dramatically improved the re-utilization of materials in lieu of new procurements, resulting in a cost savings of over $1.7 million. The FHSRS includes subprograms for manipulating the data in the database, informing of the status of a request or an item of hardware, and searching the database on any physical or other technical characteristic of a component or material. The software structure forces normalization of the data to facilitate inquiries and searches for which users have entered mixed or inconsistent values.

  3. Managing the maintenance inventory of a cement manufacturer

    Directory of Open Access Journals (Sweden)

    Morne Eloff

    2013-05-01

    Full Text Available Inventory management is a crucial aspect of managing a company successfully. This is even more apparent in the case of maintenance inventories for production equipment, which impact directly on production equipment efficiency. This is a typical inventory management issue for a cement manufacturer that faces the problem of managing its maintenance inventories optimally when certain maintenance items have exceptionally long lead times (100 weeks and values in excess of R500 000. An assessment of the cement manufacturer’s approach to managing its maintenance inventories indicated various shortcomings, which have resulted in a significant level of obsolescence. One approach to managing maintenance inventories efficiently is to implement a classification of the inventory items in terms of their criticality to the cement production process. The critical nature of a component could be established through a risk-based approach (minimisation of the risk of production loss and taking into account the type of maintenance (planned vs unplanned that the component is required for. A risk-based approach should form the basis of the maintenance inventory management of the cement manufacturer as this would allow the cement manufacturer to utilise other inventory management methods effectively. In addition, it is important to ensure that employees are well versed in the different inventory management approaches utilised and that high levels of integration between departments are pursued.

    2014-12-01

    Full Text Available Firstly, the purpose of the empirical part of the study is to analyze the inventory balances of surveyed companies and secondly, to explore the dependence between companies’ level of inventory and profitability expressed in terms of return on assets. Thirdly, the aim of the theoretical research is to explore the cost and benefits from changes in the inventory level as well as to define variables that determine net savings from changes in inventory level. An optimal inventory level should be based on consideration of incremental profitability resulting from increased merchandise with the opportunity cost of carrying higher inventory balances. The results will provide a model equation for calculating net savings from changes in inventory level as well as a new mathematical optimization model. With this model a company can consider net earnings from changes in inventory level and establish the optimal inventory level as well as improve profitability.

  6. Nash and integrated solutions in a just-in-time seller-buyer supply chain with buyer's ordering cost reductions

    Science.gov (United States)

    Lou, Kuo-Ren; Wang, Lu

    2016-05-01

    The seller frequently offers the buyer trade credit to settle the purchase amount. From the seller's prospective, granting trade credit increases not only the opportunity cost (i.e., the interest loss on the buyer's purchase amount during the credit period) but also the default risk (i.e., the rate that the buyer will be unable to pay off his/her debt obligations). On the other hand, granting trade credit increases sales volume and revenue. Consequently, trade credit is an important strategy to increase seller's profitability. In this paper, we assume that the seller uses trade credit and number of shipments in a production run as decision variables to maximise his/her profit, while the buyer determines his/her replenishment cycle time and capital investment as decision variables to reduce his/her ordering cost and achieve his/her maximum profit. We then derive non-cooperative Nash solution and cooperative integrated solution in a just-in-time inventory system, in which granting trade credit increases not only the demand but also the opportunity cost and default risk, and the relationship between the capital investment and the ordering cost reduction is logarithmic. Then, we use a software to solve and compare these two distinct solutions. Finally, we use sensitivity analysis to obtain some managerial insights.

    Splinting is a multistep procedure that is seldom performed by primary care physicians. Just-in-time training (JITT) is an emerging teaching modality and can be an invaluable asset for infrequently performed procedures or in locations where teaching resources and trained professionals are limited. Our objective was to determine the utility of JITT for teaching medical students the short-arm (SA) volar splinting technique. This was a prospective randomized controlled pilot study. An instructional video on SA volar splinting was produced. Students viewed the video or had access to standard medical textbooks (control group) immediately before applying an SA volar splint. The students were assessed for the quality of the splint via a standard 6-point skills checklist. The times required for presplinting preparation and for completion of the splint were also measured. Just-in-time training group students scored higher on the splint checklist (mean [SD], 5.45 [1.06]; 95% confidence interval [CI], 4.99-5.92 vs mean [SD], 1.58 [1.12]; 95% CI, 1.04-2.12; P teaching and disseminating procedural skills, such as SA volar splinting.

  8. JiTTree: A Just-in-Time Compiled Sparse GPU Volume Data Structure

    KAUST Repository

    Labschutz, Matthias

    2015-08-12

    Sparse volume data structures enable the efficient representation of large but sparse volumes in GPU memory for computation and visualization. However, the choice of a specific data structure for a given data set depends on several factors, such as the memory budget, the sparsity of the data, and data access patterns. In general, there is no single optimal sparse data structure, but a set of several candidates with individual strengths and drawbacks. One solution to this problem are hybrid data structures which locally adapt themselves to the sparsity. However, they typically suffer from increased traversal overhead which limits their utility in many applications. This paper presents JiTTree, a novel sparse hybrid volume data structure that uses just-in-time compilation to overcome these problems. By combining multiple sparse data structures and reducing traversal overhead we leverage their individual advantages. We demonstrate that hybrid data structures adapt well to a large range of data sets. They are especially superior to other sparse data structures for data sets that locally vary in sparsity. Possible optimization criteria are memory, performance and a combination thereof. Through just-in-time (JIT) compilation, JiTTree reduces the traversal overhead of the resulting optimal data structure. As a result, our hybrid volume data structure enables efficient computations on the GPU, while being superior in terms of memory usage when compared to non-hybrid data structures.

    2012-03-01

    Full Text Available Background: As it is well know, the implementation of instruments of logistics management is only possible with the use of the latest information technology. So-called agent technology is one of the most promising solutions in this area. Its essence consists in an entirely new way of software distribution on the computer network platform, in which computer exchange among themselves not only data, but also software modules, called just agents. The first aim is to propose the alternative method of the implementation of the concept of the inventory management by the supplier with the use of intelligent software agents, which are able not only to transfer the information but also to make the autonomous decisions based on the privileges given to them. The second aim of this research was to propose a new model of a software agent, which will be both of a high mobility and a high intelligence. Methods: After a brief discussion of the nature of agent technology, the most important benefits of using it to build platforms to support business are given. Then the original model of polymorphic software agent, called Multi-Dimensionally Versioned Software Agent (MDV is presented, which is oriented on the specificity of IT applications in business. MDV agent is polymorphic, which allows the transmission through the network only the most relevant parts of its code, and only when necessary. Consequently, the network nodes exchange small amounts of software code, which ensures high mobility of software agents, and thus highly efficient operation of IT platforms built on the proposed model. Next, the adaptation of MDV software agents to implementation of well-known logistics management instrument - VMI (Vendor Managed Inventory is illustrated. Results: The key benefits of this approach are identified, among which one can distinguish: reduced costs, higher flexibility and efficiency, new functionality - especially addressed to business negotiation, full automation

    2016-01-01

    Full Text Available The problem addressed in this paper is the two-machine job shop scheduling problem when the objective is to minimize the total earliness and tardiness from a common due date (CDD for a set of jobs when their weights equal 1 (unweighted problem. This objective became very significant after the introduction of the Just in Time manufacturing approach. A procedure to determine whether the CDD is restricted or unrestricted is developed and a semirestricted CDD is defined. Algorithms are introduced to find the optimal solution when the CDD is unrestricted and semirestricted. When the CDD is restricted, which is a much harder problem, a heuristic algorithm is proposed to find approximate solutions. Through computational experiments, the heuristic algorithms’ performance is evaluated with problems up to 500 jobs.

    2011-10-01

    Full Text Available The Just-in-Time (JIT philosophy originated from the Toyota Production System (TPS and has been used in the manufacturing industry for many decades. It has helped to increase the productivity of the industry and has also increased the quality of its products. In recent years, numerous studies in developed countries have endeavoured to introduce JIT in the construction industry to reap similar benefits. This study focused on applying JIT to the Chinese construction industry with the goal of improving its performance and thus its competitiveness. This paper discusses the current state of the Chinese construction industry; presents the potential impediments to implementing JIT; and proposes a framework for JIT implementation in the areas of design, procurement, construction and inspection. The results of this study suggest that government and educational institutions should play a key role in spearheading the application of JIT in the construction industry in China.

    2008-04-01

    An RFID-based mobile handheld inventory management system is proposed in this paper. Differing from the manual inventory management method, the proposed system works on the personal digital assistant (PDA) with an RFID reader. The system identifies electronic tags on the properties and checks the property information in the back-end database server through a ubiquitous wireless network. The system also provides a set of functions to manage the back-end inventory database and assigns different levels of access privilege according to various user categories. In the back-end database server, to prevent improper or illegal accesses, the server not only stores the inventory database and user privilege information, but also keeps track of the user activities in the server including the login and logout time and location, the records of database accessing, and every modification of the tables. Some experimental results are presented to verify the applicability of the integrated RFID-based mobile handheld inventory management system.

This quantitative study is important to the manufacturing organization in Malaysia because it provides the guidelines to the employers of manufacturing small medium enterprises in Batu Pahat, Johor.

  4. BIM-Integrated Construction Operation Simulation for Just-In-Time Production Management

    Directory of Open Access Journals (Sweden)

    WoonSeong Jeong

    2016-10-01

    Full Text Available Traditional construction planning, which depends on historical data and heuristic modification, prevents the integration of managerial details such as productivity dynamics. Specifically, the distance between planning and execution brings cost overruns and duration extensions. To minimize variations, this research presents a Building Information Modeling (BIM-integrated simulation framework for predicting productivity dynamics at the construction planning phase. To develop this framework, we examined critical factors affecting productivity at the operational level, and then forecast the productivity dynamics. The resulting plan includes specific commands for retrieving the required information from BIM and executing operation simulations. It consists of the following steps: (1 preparing a BIM model to produce input data; (2 composing a construction simulation at the operational level; and (3 obtaining productivity dynamics from the BIM-integrated simulation. To validate our framework, we applied it to a structural steel model; this was due to the significance of steel erections. By integrating BIM with construction operation simulations, we were able to create reliable construction plans that adapted to project changes. Our results show that the developed framework facilitates the reliable prediction of productivity dynamics, and can contribute to improved schedule reliability, optimized resource allocation, cost savings associated with buffers, and reduced material waste.

  10. Just-in-Time Compilation-Inspired Methodology for Parallelization of Compute Intensive Java Code

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Compute intensive programs generally consume significant fraction of execution time in a small amount of repetitive code. Such repetitive code is commonly known as hotspot code. We observed that compute intensive hotspots often possess exploitable loop level parallelism. A JIT (Just-in-Time compiler profiles a running program to identify its hotspots. Hotspots are then translated into native code, for efficient execution. Using similar approach, we propose a methodology to identify hotspots and exploit their parallelization potential on multicore systems. Proposed methodology selects and parallelizes each DOALL loop that is either contained in a hotspot method or calls a hotspot method. The methodology could be integrated in front-end of a JIT compiler to parallelize sequential code, just before native translation. However, compilation to native code is out of scope of this work. As a case study, we analyze eighteen JGF (Java Grande Forum benchmarks to determine parallelization potential of hotspots. Eight benchmarks demonstrate a speedup of up to 7.6x on an 8-core system

    Full Text Available This paper presents a combination of variable neighbourhood search and mathematical programming to minimize the sum of earliness and tardiness penalty costs of all operations for just-in-time job-shop scheduling problem (JITJSSP. Unlike classical E/T scheduling problem with each job having its earliness or tardiness penalty cost, each operation in this paper has its earliness and tardiness penalties, which are paid if the operation is completed before or after its due date. Our hybrid algorithm combines (i a variable neighbourhood search procedure to explore the huge feasible solution spaces efficiently by alternating the swap and insertion neighbourhood structures and (ii a mathematical programming model to optimize the completion times of the operations for a given solution in each iteration procedure. Additionally, a threshold accepting mechanism is proposed to diversify the local search of variable neighbourhood search. Computational results on the 72 benchmark instances show that our algorithm can obtain the best known solution for 40 problems, and the best known solutions for 33 problems are updated.

  12. HOPE: A Python Just-In-Time compiler for astrophysical computations

    Akeret, Joel; Amara, Adam; Refregier, Alexandre

    2014-01-01

    The Python programming language is becoming increasingly popular for scientific applications due to its simplicity, versatility, and the broad range of its libraries. A drawback of this dynamic language, however, is its low runtime performance which limits its applicability for large simulations and for the analysis of large data sets, as is common in astrophysics and cosmology. While various frameworks have been developed to address this limitation, most focus on covering the complete language set, and either force the user to alter the code or are not able to reach the full speed of an optimised native compiled language. In order to combine the ease of Python and the speed of C++, we developed HOPE, a specialised Python just-in-time (JIT) compiler designed for numerical astrophysical applications. HOPE focuses on a subset of the language and is able to translate Python code into C++ while performing numerical optimisation on mathematical expressions at runtime. To enable the JIT compilation, the user only n...

    Full Text Available Indian Corrugated Packaging Industries (ICPI have built up tough competition among the industries in terms of product cost, quality, product delivery, flexibility, and finally customer’s demand. As their customers, mostly OEMs are asking Just in Time deliveries, ICPI must implement JIT in their system. The term "JIT” as, it denotes a system that utilizes less, in terms of all inputs, to create the same outputs as those created by a traditional mass production system, while contributing increased varieties for the end customer. (Womack et al. 1990 "JIT" focuses on abolishing or reducing Muda (“Muda", the Japanese word for waste and on maximizing or fully utilizing activities that add value from the customer's perspective. There is lack of awareness in identifying the right enablers of JIT implementation. Therefore, this study has tried to find out the enablers from the literature review and expert’s opinions from corrugated packaging industries and developed the relationship matrix to see the driving power and dependence between them. In this study, modeling has been done in order to know the interrelationships between the enablers with the help of Interpretive Structural Modeling and Cross Impact Matrix Multiplication Applied to Classification (MICMAC analysis for the performance of Indian corrugated packaging industries.

    2015-01-01

    Objective This paper presents an experimental design, the micro-randomized trial, developed to support optimization of just-in-time adaptive interventions (JITAIs). JITAIs are mHealth technologies that aim to deliver the right intervention components at the right times and locations to optimally support individuals’ health behaviors. Micro-randomized trials offer a way to optimize such interventions by enabling modeling of causal effects and time-varying effect moderation for individual intervention components within a JITAI. Methods The paper describes the micro-randomized trial design, enumerates research questions that this experimental design can help answer, and provides an overview of the data analyses that can be used to assess the causal effects of studied intervention components and investigate time-varying moderation of those effects. Results Micro-randomized trials enable causal modeling of proximal effects of the randomized intervention components and assessment of time-varying moderation of those effects. Conclusions Micro-randomized trials can help researchers understand whether their interventions are having intended effects, when and for whom they are effective, and what factors moderate the interventions’ effects, enabling creation of more effective JITAIs.

    Takahiro Kosaki

    2014-01-01

    Full Text Available Parallel mechanisms have advantages such as high power, high stiffness, and high precision due to the parallel arrangement of actuators, in comparison with typical serial mechanisms. In the present study, we used pneumatic linear drives to develop a linearly actuated parallel mechanism, in which the actuators fixed on a base enable high degrees of freedom of motion of an end-effector. Using pneumatic linear drives in the realization of such a parallel mechanism leads to lightweight, compact, and low-cost construction. For the parallel mechanism prototype, we construct a control system based on our previously proposed networked Just-In-Time (JIT control strategy, which is based on client-server architecture. In this system, the parallel mechanism is connected to a client computer, and a server computer has a database that stores the control data for all the pneumatic actuators to drive the parallel mechanism. The client online accesses the database, receives data from the server, and feeds control commands to the pneumatic actuators. Experiments were performed to investigate the performance of the developed parallel mechanism system.

    Full Text Available The Just-In-Time (JIT scheduling problem is an important subject of study. It essentially constitutes the problem of scheduling critical business resources in an attempt to optimize given business objectives. This problem is NP-Hard in nature, hence requiring efficient solution techniques. To solve the JIT scheduling problem presented in this study, a new local search metaheuristic algorithm, namely, the enhanced Best Performance Algorithm (eBPA, is introduced. This is part of the initial study of the algorithm for scheduling problems. The current problem setting is the allocation of a large number of jobs required to be scheduled on multiple and identical machines which run in parallel. The due date of a job is characterized by a window frame of time, rather than a specific point in time. The performance of the eBPA is compared against Tabu Search (TS and Simulated Annealing (SA. SA and TS are well-known local search metaheuristic algorithms. The results show the potential of the eBPA as a metaheuristic algorithm.

    The attachment of bacteria to surfaces provides advantages such as increasing nutrient access and resistance to environmental stress. Attachment begins with a reversible phase, often mediated by surface structures such as flagella and pili, followed by a transition to irreversible attachment, typically mediated by polysaccharides. Here we show that the interplay between pili and flagellum rotation stimulates the rapid transition between reversible and polysaccharide-mediated irreversible attachment. We found that reversible attachment of Caulobacter crescentus cells is mediated by motile cells bearing pili and that their contact with a surface results in the rapid pili-dependent arrest of flagellum rotation and concurrent stimulation of polar holdfast adhesive polysaccharide. Similar stimulation of polar adhesin production by surface contact occurs in Asticcacaulis biprosthecum and Agrobacterium tumefaciens. Therefore, single bacterial cells respond to their initial contact with surfaces by triggering just-in-time adhesin production. This mechanism restricts stable attachment to intimate surface interactions, thereby maximizing surface attachment, discouraging non-productive self-adherence, and preventing curing of the adhesive.

    2010-07-01

    We propose a new one-way resource reservation protocol for optical burst switching (OBS) networks, called Enhanced Just-in-Time Plus (E-JIT+). The protocol is described in detail, and its formal specification is presented, following an extended finite state machine approach. The performance evaluation of E-JIT+ is analyzed in comparison with other proposed OBS protocols (JIT+ and E-JIT) for the following network topologies: rings; degree-two, degree-three, and degree-four chordal rings; mesh-torus; NSFNET; ARPANET; FCCN-NET; and the European Optical Network. We evaluate and compare the performance of the different protocols in terms of burst loss probability, taking into account the most important OBS network parameters. It was shown that E-JIT+ performs better than available one-way resource reservation protocols for all the evaluated network topologies. Moreover, the scalability of E-JIT+ was observed, and when the network traffic increases, the burst loss probability also increases, leading to a worse network performance.

    2016-01-01

    Full Text Available Numerous studies show that the implementation of Vendor Managed Inventory (VMI benefits all members of the supply chain. This research develops model to prove the benefits obtained from implementing VMI to supplier-buyer partnership analytically. The model considers a two-level supply chain which consists of a single supplier and a single buyer. The analytical model is developed to supply chain inventory with probabilistic demand which follows normal distribution. The model also incorporates lead time as a decision variable and investigates the impacts of inventory management before and after the implementation of the VMI. The result shows that the analytical model has the ability to reduce the supply chain expected cost, improve the service level and increase the inventory replenishment. Numerical examples are given to prove them.

HOPE focuses on a subset of the language and is able to translate Python code into C++ while performing numerical optimisation on mathematical expressions at runtime. To enable the JIT compilation, the user only needs to add a decorator to the function definition. We assess the performance of HOPE by performing a series of benchmarks and compare its execution speed with that of plain Python, C++ and the other existing frameworks. We find that HOPE improves the performance compared to plain Python by a factor of 2 to 120, achieves speeds comparable to that of C++, and often exceeds the speed of the existing solutions. We discuss the differences between HOPE and the other frameworks, as well as future extensions of its capabilities. The fully documented HOPE package is available at http://hope.phys.ethz.ch and is published under the GPLv3 license on PyPI and GitHub.

    2017-08-28

    Just-in-time training (JITT) has been used to teach and re-teach known medical techniques, but has not been used to teach novel techniques. We aimed to assess the performance retention of JITT on a novel asthma exacerbation severity assessment technique known as Los Angeles (LA) Phonospirometry. This was a prospective cohort study using a convenience sample of pediatric emergency department registered nurses (RNs) who were asked to watch a brief instructional digital video on LA Phonospirometry, and then asked to practice the technique on a research assistant (RA). A checklist was used to evaluate proficiency with the primary outcome being the number correct on the checklist. The secondary outcome included whether or not they could identify a common error demonstrated by the RA. RNs were re-tested after 4-6 months to assess skill retention. Forty RNs were enrolled in the study and 6 were lost to follow-up. The mean time from the first to second testing was 5.4 months +/- 0.5 months. The mean score of the first part of the checklist on the initial testing was 4.6 +/- 0.7 and on second testing was 3.8 +/- 1.5 (p = 0.008). This represented a drop in scores and thus minimal knowledge decay of 18% (from 91% to 73%). The mean for number of errors picked up for the first test and second test were 1.3 and 1.5, respectively (p = 0.2). JITT demonstrated feasibility as a rapid instructional tool for RNs, with a limited decay in cognitive knowledge surrounding the LA Phonospirometry technique.

    2016-01-01

    Full Text Available Concrete is the backbone of any developed economy. Concrete can suffer from a large number of deleterious effects including physical, chemical and biological causes. Large owning bridge structures organizations are facing very serious questions when asking for maintenance budgets. The questions range from needing to justify the need for the work, its urgency, to also have to predict or show the consequences of delayed rehabilitation of a particular structure. There is therefore a need for a probabilistic model that can estimate the range of service lives of bridge populations and also the likelihood of level of deteriorations it can reached for every incremental time interval. A model was developed for such estimation based on statistical data from actual inspection records of a large reinforced concrete bridge portfolio. The method used both deterministic and stochastic methods to predict the service life of a bridge, using these service lives in combination with the just in time (JIT principle of management would enable maintenance managers to justify the need for action and the budgets needed, to intervene at the optimum time in the life of the structure and that of the deterioration. The paper will report on the model which is based on a large database of deterioration records of concrete bridges covering a period of over 60 years and include data from over 400 bridge structures. The paper will also illustrate how the service life model was developed and how these service lives combined with the JIT can be used to effectively allocate resources and use them to keep a major infrastructure asset moving with little disruption to the transport system and its users.

  12. Application of just-in-time manufacturing techniques in radioactive source in well logging industry

    2017-03-01

    Full Text Available Nuclear logging is one of major areas of logging development. This paper presents an empirical investigation to bring the drilling and completion of wells from an ill-defined art to a refined sci-ence by using radioactive source to “look and measure” such as formation type, formation dip, porosity, fluid type and numerous other important factors. The initial nuclear logging tools rec-ords the radiation emitted by formation as they were crossed by boreholes. Gamma radiation is used in well logging as it is powerful enough to penetrate the formation and steel casing. The ra-dioactive source is reusable so that after engineer finished the job the radioactive source is sent back to bunker. In this case inventory level of radioactive source is relatively high compared with monthly movement and the company must spend large amount of cost just for inventory. After calculating and averaging the monthly movement in 2014 and 2015, we detected a big pos-sibility to cut the inventory level to reduce the inventory cost.

    2012-06-15

    We address a problem of inventory management of spare parts in the context of a large energy company, producer of oil and gas. Spare parts are critical for assuring operational conditions in offshore platforms. About 200,000 different items are held in several inventory plants. The inventory system implemented at the company corresponds to a min-max system. The control parameters are decided based mainly on the expert judgment of the planners. Also, though the inventory plants can in practice be supplied from each other, the inventory planning is performed separately by the plant planners. This is because of different ownership structures where the studied company has the operative responsibility. The company is pursuing a system in which all planners conform to the same inventory management approach and evaluation, as well as being more cost efficient. Our work focuses on supporting this goal. We apply methods to decide the inventory control parameters for this system under a service level constraint. The methodology we use distinguishes unit-size and lot-size demand cases. We perform computational experiments to find control parameters for a sample of items. After the control parameters are found, we use them to explore the impact of risk pooling among the plants and inaccuracy arising from duplicate item codes.(Author)

  5. Just in time or Just in case: A Case study on the impact of context in ERP implementations

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available This paper looks at a case study of an Enterprise Resource Planning System (ERP implementation in a geographically dispersed utility company and the approach by middle management to several problem situations involving contextual issues and end-user developed (feral systems. The paper contends that despite the extremely effective databases and sophisticated modules for business analytic functions within most ERP’s, middle managers are still in the “just in case of an incident” mode of inventory management and data entered in their own feral systems may be significantly different to the inventory levels recorded in the main ERP. We contend that these problems point towards the failure of ERP systems to be context sensitive to organisations. It highlights problems in contemporary research which appears to lack understanding of different organisational contexts and how they could impact on ERP implementations. This paper argues that context and the ideals of ERP systems are often mismatched which leads to the development of feral systems, poor inventory practices and ERP systems implementation failure. The paper discusses the literature around ERP systems implementation and argues that context is an overlooked factor in the analysis of such systems. The paper uses case study evidence to demonstrate mismatched context and highlights the problems with assuming ERP systems are one size fits all. The paper concludes with a call to build more contextual research in the study of ERP implementations.

    2005-04-01

    In price-sensitive markets, price promotions coupled with an appropriate item replenishment strategy can be effective in controlling the total costs of servicing the market. In supply chains that handle perishable products, inventory management is already a complex problem and the management of products in a dynamic-pricing environment is even more challenging. Monitoring and control of time-sensitive products can be facilitated by the application of radio frequency identification (RFID) technology, which enables non-contact, real-time data collection and efficient interfacing with the management control system in the supply chain. This paper describes an integrated framework for inventory management and pricing in a discrete time (periodic review and ordering) framework, and describes an efficient algorithm, including a new approximation, for the related optimization problem. We then propose a suitable architecture for the application of RFID technology in this context, to realize the potential benefits.

    Full Text Available Background: An advantage of the high portability and sensing capabilities of smartphones is the potential for health apps to deliver advice and support to individuals close in time to when it is deemed of greatest relevance and impact, often referred to as Just In Time Adaptive Interventions (JITAI. However, little research has been undertaken to explore the viability of JITAI in terms of how long it takes users to engage with support triggered by real time data input, compared to scheduled support, and whether context affects response. This paper is focused on Q Sense, a smoking cessation app developed to deliver both Just in Time and scheduled support messages (every morning during a smoker’s quit attempt. The Just in Time cessation support generated by Q Sense is triggered by and tailored to real time context using location sensing. Objectives: To assess: 1 the time to engage with the app after a Just in Time support notification is delivered and whether this is influenced by the context in which the notification was initially delivered, 2 whether the time to engage with the app differs between Just in Time support notifications and scheduled support message notifications and 3 whether findings from objectives 1 and 2 differ between smokers receiving or not receiving NHS smoking cessation support. Methods: Data are from two studies evaluating the use of Q Sense: a feasibility study using an opportunity sample of smokers initiating a quit attempt with Q Sense without NHS cessation support (N=15 and an ongoing acceptability study of smokers receiving NHS smoking cessation support alongside app use (target N=40, recruitment due to be completed end of November 2015. Time elapse between notification generation and the user opening the app will be calculated and compared between message types (Just in Time vs. scheduled messages, contexts (home, work, socialising, other and samples (receiving or not receiving NHS cessation support using t

    High-fidelity simulation using patient-specific three-dimensional (3D) models may be effective in facilitating pediatric cardiac intensive care unit (PCICU) provider training for clinical management of congenital cardiac surgery patients. The 3D-printed heart models were rendered from preoperative cross-sectional cardiac imaging for 10 patients undergoing congenital cardiac surgery. Immediately following surgical repair, a congenital cardiac surgeon and an intensive care physician conducted a simulation training session regarding postoperative care utilizing the patient-specific 3D model for the PCICU team. After the simulation, Likert-type 0 to 10 scale questionnaire assessed participant perception of impact of the training session. Seventy clinicians participated in training sessions, including 22 physicians, 38 nurses, and 10 ancillary care providers. Average response to whether 3D models were more helpful than standard hand off was 8.4 of 10. Questions regarding enhancement of understanding and clinical ability received average responses of 9.0 or greater, and 90% of participants scored 8 of 10 or higher. Nurses scored significantly higher than other clinicians on self-reported familiarity with the surgery (7.1 vs. 5.8; P = .04), clinical management ability (8.6 vs. 7.7; P = .02), and ability enhancement (9.5 vs. 8.7; P = .02). Compared to physicians, nurses and ancillary providers were more likely to consider 3D models more helpful than standard hand off (8.7 vs. 7.7; P = .05). Higher case complexity predicted greater enhancement of understanding of surgery (P = .04). The 3D heart models can be used to enhance congenital cardiac critical care via simulation training of multidisciplinary intensive care teams. Benefit may be dependent on provider type and case complexity. © The Author(s) 2016.

Within first year modules on Pharmaceutical Biology and Integrative Physiology in the Masters of Pharmacy degree at Robert Gordon University (RGU several software tools were used to support both lecture and coursework material for the immune and integumentary systems. However, students had difficulty visualizing the various layers of the skin and how they become affected by different skin lesions. As a response to these identified learning difficulties, a just-in-time teaching 3-Dimensional elearning object was developed using free-to-use 3D CAD packages alongside common elearning software. The outcome was a virtualised human arm equipped to illustrate and label primary or secondary skin lesions whilst allowing spatial manipulation of the arm. This allowed students to manipulate and identify the specific skin layers involved. Evaluation of student engagement and learning was favourable, with students reflecting that they had a better understanding of the topic. Initial findings from this study highlight the benefits of quick, low-cost 3D production processes as just-in-time teaching elearning tools that have a positive impact on students’ performance.

  18. On the Feasibility and Limitations of Just-in-Time Instruction Set Extension for FPGA-Based Reconfigurable Processors

    Full Text Available Reconfigurable instruction set processors provide the possibility of tailor the instruction set of a CPU to a particular application. While this customization process could be performed during runtime in order to adapt the CPU to the currently executed workload, this use case has been hardly investigated. In this paper, we study the feasibility of moving the customization process to runtime and evaluate the relation of the expected speedups and the associated overheads. To this end, we present a tool flow that is tailored to the requirements of this just-in-time ASIP specialization scenario. We evaluate our methods by targeting our previously introduced Woolcano reconfigurable ASIP architecture for a set of applications from the SPEC2006, SPEC2000, MiBench, and SciMark2 benchmark suites. Our results show that just-in-time ASIP specialization is promising for embedded computing applications, where average speedups of 5x can be achieved by spending 50 minutes for custom instruction identification and hardware generation. These overheads will be compensated if the applications execute for more than 2 hours. For the scientific computing benchmarks, the achievable speedup is only 1.2x, which requires significant execution times in the order of days to amortize the overheads.

    Energy Technology Data Exchange (ETDEWEB)

    DeVault, Robert C [ORNL

    2009-01-01

    Conventional methods of vehicle operation for Plug-in Hybrid Vehicles first discharge the battery to a minimum State of Charge (SOC) before switching to charge sustaining operation. This is very demanding on the battery, maximizing the number of trips ending with a depleted battery and maximizing the distance driven on a depleted battery over the vehicle s life. Several methods have been proposed to reduce the number of trips ending with a deeply discharged battery and also eliminate the need for extended driving on a depleted battery. An optimum SOC can be maintained for long battery life before discharging the battery so that the vehicle reaches an electric plug-in destination just as the battery reaches the minimum operating SOC. These Just-in-Time methods provide maximum effective battery life while getting virtually the same electricity from the grid.

    2005-11-07

    Soft-tissue target motion is one of the main concerns in high-precision radiation therapy. Cone beam computed tomography (CBCT) has been developed recently to image soft-tissue targets in the treatment room and guide the radiation therapy treatment. However, due to its relatively long image acquisition time the CBCT approach cannot provide images of the target at the instant of the treatment and thus it is not adequate for imaging targets with intrafraction motion. In this note, a new approach for image-guided radiation therapy-just-in-time tomography (JiTT)-is proposed. Differing from CBCT, JiTT takes much less time to generate the needed tomographical, beam's-eye-view images of the treatment target at the right moment to guide the radiation therapy treatment.

It incorporates Earliness/Tardiness (E/T penalties, interruption penalties and holding cost of jobs which are waiting to be processed as work-in-process (WIP. Generally in non-preemptive problems, E/T penalties are a function of the completion time of the jobs. Then, we introduce a non-linear preemptive scheduling model where the earliness penalty depends on the starting time of a job. The model is liberalized by an elaborately–designed procedure to reach the optimum solution. To validate and verify the performance of proposed model, computational results are presented by solving a number of numerical examples.

    Full Text Available In today’s competitive global markets, Just-in-Time (JIT is one of the main lean manufacturing approaches. It is used in organizations to improve performance and reduce costs and as a strategic core capability to ensure their market position. However, using JIT tightly couples various functions of the Supply Chain and increases the risk of propagating disruptions through the entire system. This study presents an ordering strategy for the supply of raw materials to the production system to meet customer satisfaction. A general model for cost-risk reduction is developed embracing multiple external and local backup suppliers. The outcomes from this model will be used to obtimise the simultaneous cost/risk reduction within JIT systems. The effectiveness of the developed model will be validated using a simplified example.

  13. Optimizing python-based ROOT I/O with PyPy's tracing just-in-time compiler

    Science.gov (United States)

    Tlp Lavrijsen, Wim

    2012-12-01

    The Python programming language allows objects and classes to respond dynamically to the execution environment. Most of this, however, is made possible through language hooks which by definition can not be optimized and thus tend to be slow. The PyPy implementation of Python includes a tracing just in time compiler (JIT), which allows similar dynamic responses but at the interpreter-, rather than the application-level. Therefore, it is possible to fully remove the hooks, leaving only the dynamic response, in the optimization stage for hot loops, if the types of interest are opened up to the JIT. A general opening up of types to the JIT, based on reflection information, has already been developed (cppyy). The work described in this paper takes it one step further by customizing access to ROOT I/O to the JIT, allowing for fully automatic optimizations.

  14. OTUS - Reactor inventory management system based on ORIGEN2

    Energy Technology Data Exchange (ETDEWEB)

    Poellaenen, R.; Toivonen, H.; Lahtinen, J.; Ilander, T.

    1995-10-01

    ORIGEN2 is a computer code that calculates nuclide composition and other characteristics of nuclear fuel. The use of ORIGEN2 requires good knowledge in reactor physics. However, once the input has been defined for a particular reactor type, the calculations can be easily repeated for any burnup and decay time. This procedure produces large output files that are difficult to handle manually. A new computer code, known as OTUS, was designed to facilitate the postprocessing of the data. OTUS makes use of the inventory files precalculated with ORIGEN2 in a way that enables their versatile treatment for different safety analysis purposes. A data base is created containing a comprehensive set of ORIGEN2 calculations as a function of fuel burnup and decay time. OTUS is a reactor inventory management system for a microcomputer with Windows interface. Four major data operations are available: (1) Build data modifies ORIGEN2 output data into a suitable format, (2) View data enables flexible presentation of the data as such, (3) Different calculations, such as nuclide ratios and hot particle characteristics, can be performed for severe accident analyses, consequence analyses and research purposes, (4) Summary files contain both burnup dependent and decay time dependent inventory information related to the nuclide and the reactor specified. These files can be used for safeguards, radiation monitoring and safety assessment. (orig.) (22 refs., 29 figs.).

    In the 199os, Hewlett-Packard's PC business was struggling to turn a dollar, despite the company's success in winning market share. By 1997, margins on its PCs were as thin as a silicon wafer, and some product lines hadn't turned a profit since 1993. The problem had everything to do with the PC industry's notoriously short product cycles and brutal product and component price deflation. A common rule of thumb was that the value of a fully assembled PC decreased 1% a week. In such an environment, inventory costs become critical. But not just the inventory costs companies traditionally track, HP found, after a thorough review of the problem. The standard "holding cost of inventory"--the capital and physical costs of inventory--accounted for only about 10% of HP's inventory costs. The greater risks, it turned out, resided in four other, essentially hidden costs, which stemmed from mismatches between demand and supply: Component devaluation costs for components still held in production; Price protection costs incurred when product prices drop on the goods distributors still have on their shelves; Product return costs that have to be absorbed when distributors return and receive refunds on overstock items, and; Obsolescence costs for products still unsold when new models are introduced. By developing metrics to track those costs in a consistent way throughout the PC division, HP has found it can manage its supply chains with much more sophistication. Gone are the days of across-the-board measures such as,"Everyone must cut inventories by 20% by the end of the year," which usually resulted in a flurry of cookie-cutter lean production and just-in-time initiatives. Now, each product group is free to choose the supply chain configuration that best suits its needs. Other companies can follow HP's example.

  1. Defense Nuclear Material Stewardship Integrated Inventory Information Management System (IIIMS).

    Energy Technology Data Exchange (ETDEWEB)

    Aas, Christopher A.; Lenhart, James E.; Bray, Olin H.; Witcher, Christina Jenkin

    2004-11-01

    Sandia National Laboratories was tasked with developing the Defense Nuclear Material Stewardship Integrated Inventory Information Management System (IIIMS) with the sponsorship of NA-125.3 and the concurrence of DOE/NNSA field and area offices. The purpose of IIIMS was to modernize nuclear materials management information systems at the enterprise level. Projects over the course of several years attempted to spearhead this modernization. The scope of IIIMS was broken into broad enterprise-oriented materials management and materials forecasting. The IIIMS prototype was developed to allow multiple participating user groups to explore nuclear material requirements and needs in detail. The purpose of material forecasting was to determine nuclear material availability over a 10 to 15 year period in light of the dynamic nature of nuclear materials management. Formal DOE Directives (requirements) were needed to direct IIIMS efforts but were never issued and the project has been halted. When restarted, duplicating or re-engineering the activities from 1999 to 2003 is unnecessary, and in fact future initiatives can build on previous work. IIIMS requirements should be structured to provide high confidence that discrepancies are detected, and classified information is not divulged. Enterprise-wide materials management systems maintained by the military can be used as overall models to base IIIMS implementation concepts upon.

  2. Hybrid Metaheuristics for the Unrelated Parallel Machine Scheduling to Minimize Makespan and Maximum Just-in-Time Deviations

    2012-06-01

    Full Text Available This paper studies the unrelated parallel machine scheduling problem with three minimization objectives – makespan, maximum earliness, and maximum tardiness (MET-UPMSP. The last two objectives combined are related to just-in-time (JIT performance of a solution. Three hybrid algorithms are presented to solve the MET-UPMSP: reactive GRASP with path relinking, dual-archived memetic algorithm (DAMA, and SPEA2. In order to improve the solution quality, min-max matching is included in the decoding scheme for each algorithm. An experiment is conducted to evaluate the performance of the three algorithms, using 100 (jobs x 3 (machines and 200 x 5 problem instances with three combinations of two due date factors – tight and range. The numerical results indicate that DAMA performs best and GRASP performs second for most problem instances in three performance metrics: HVR, GD, and Spread. The experimental results also show that incorporating min-max matching into decoding scheme significantly improves the solution quality for the two population-based algorithms. It is worth noting that the solutions produced by DAMA with matching decoding can be used as benchmark to evaluate the performance of other algorithms.

    2010-01-01

    Objective of the current work is to develop an Optical Character Recognition (OCR) engine for information Just In Time (iJIT) system that can be used for recognition of handwritten textual annotations of lower case Roman script. Tesseract open source OCR engine under Apache License 2.0 is used to develop user-specific handwriting recognition models, viz., the language sets, for the said system, where each user is identified by a unique identification tag associated with the digital pen. To generate the language set for any user, Tesseract is trained with labeled handwritten data samples of isolated and free-flow texts of Roman script, collected exclusively from that user. The designed system is tested on five different language sets with free- flow handwritten annotations as test samples. The system could successfully segment and subsequently recognize 87.92%, 81.53%, 92.88%, 86.75% and 90.80% handwritten characters in the test samples of five different users.

    Simulation-based skill trainings are common; however, optimal instructional designs that improve outcomes are not well specified. We explored the impact of just-in-time and just-in-place training (JIPT) on interns' infant lumbar puncture (LP) success. This prospective study enrolled pediatric and emergency medicine interns from 2009 to 2012 at 34 centers. Two distinct instructional design strategies were compared. Cohort A (2009-2010) completed simulation-based training at commencement of internship, receiving individually coached practice on the LP simulator until achieving a predefined mastery performance standard. Cohort B (2010-2012) had the same training plus JIPT sessions immediately before their first clinical LP. Main outcome was LP success, defined as obtaining fluid with first needle insertion and intern success rates with infant LP are poor. Despite improving process measures, adding JIPT to training bundles did not improve success rate. More research is needed on optimal instructional design strategies for infant LP.

    The just-in-time adaptive intervention (JITAI) is an intervention design aiming to provide the right type/amount of support, at the right time, by adapting to an individual's changing internal and contextual state. The availability of increasingly powerful mobile and sensing technologies underpins the use of JITAIs to support health behavior, as in such a setting an individual's state can change rapidly, unexpectedly, and in his/her natural environment. Despite the increasing use and appeal of JITAIs, a major gap exists between the growing technological capabilities for delivering JITAIs and research on the development and evaluation of these interventions. Many JITAIs have been developed with minimal use of empirical evidence, theory, or accepted treatment guidelines. Here, we take an essential first step towards bridging this gap. Building on health behavior theories and the extant literature on JITAIs, we clarify the scientific motivation for JITAIs, define their fundamental components, and highlight design principles related to these components. Examples of JITAIs from various domains of health behavior research are used for illustration. As we enter a new era of technological capacity for delivering JITAIs, it is critical that researchers develop sophisticated and nuanced health behavior theories capable of guiding the construction of such interventions. Particular attention has to be given to better understanding the implications of providing timely and ecologically sound support for intervention adherence and retention.

    Just-in-Time Teaching (JiTT) is an instructional strategy involving feedback from students on prelecture activities in order to design in-class activities to build on the continuing feedback from students. We investigate the effectiveness of a JiTT approach, which included in-class concept tests using clickers in an upper-division quantum mechanics course. We analyze student performance on prelecture reading quizzes, in-class clicker questions answered individually, and clicker questions answered after group discussion, and compare those performances with open-ended retention quizzes administered after all instructional activities on the same concepts. In general, compared to the reading quizzes, student performance improved when individual clicker questions were posed after lectures that focused on student difficulties found via electronic feedback. The performance on the clicker questions after group discussion following individual clicker question responses also showed improvement. We discuss some possible reasons for the improved performance at various stages, e.g., from prelecture reading quizzes to postlecture clicker questions, and from individual to group clicker questions.

  7. Integrated model for line balancing with workstation inventory management

    2010-06-01

    Full Text Available In this paper, we address the optimization of an integrated line balancing process with workstation inventory management. While doing so, we have studied the interconnection between line balancing and its conversion process. Almost each and every moderate to large manufacturing industry depends on a long and integrated supply chain, consisting of inbound logistic, conversion process and outbound logistic. In this sense an approach addresses a very general problem of integrated line balancing. Research works reported in the literature so far mainly deals with minimization of cost for inbound and outbound logistic subsystems. In most of the cases conversion process has been ignored. We suggest a generic approach for linking the balancing of the line of production in the conversion area with the customers’ rate of demand in the market and for configuring the related stock chambers. Thus, the main aim of this paper is to translate the underlying problem in the form of mixed nonlinear programming problem and design the optimum supply chain so that the total inventory cost and the cost of balancing loss of the conversion process is jointly minimized and ideal cycle time of the production process is determined along with ideal sizes of the stock chambers. A numerical example has been added to demonstrate the suitability of our approach.

  8. Vendor managed inventory in multi level supply chain

    2017-01-01

    Full Text Available Vendor managed inventory (VMI is one of the most effective methods for reducing bullwhip effect. This paper presents a mathematical VMI model where there are three levels of central storage, multi distribution centers and various retailors. The problem is formulated as a mixed integer programming by considering uncertainty on different input parameters. To cope with uncertainty, the study uses rectangular fuzzy numbers. We also propose two metaheuristics; namely, genetic algorithm and particle swarm optimization to solve the resulted problems for some large instances. The preliminary results have indicated that genetic algorithm could solve the proposed model faster than particle swarm optimization in terms of CPU time reaching to slightly better objective functions.

    1986-04-01

    Automated identification systems (bar coding) have proven their worth in a number of diverse manufacturing and materials handling environments. Whether this technology can be broadly applied with equal effectiveness in the health care setting still remains largely unproven. One thing is certain, however. Before bar code technology can be effectively applied in any setting, the materials manager must understand several basic concepts: How materials flow through his physical plant; How, where and in what amounts they are used; and How and when they are expensed. With this information, it is possible to create a systematized approach to materials cost containment, of which bar coding is one element. In the following article, the author illustrates how purchasing and inventory control can be made more time and labor efficient through the use of bar code technology.

    Full Text Available Vendor Managed Inventory (VMI is one of the effective techniques for managing theinventory in supply chain. VMI models have been proven to reduce the cost of inventorycompared with traditional economic order quantity method under some conditions such asconstant demand and production expenditure. However, the modeling of the VMI problem hasnever been studied under some realistic assumptions such as price dependent demand. In thispaper, three problem formulations are proposed. In the first problem formulation, we study aVMI problem with one buyer and one supplier when demand is considered to be a function ofprice and price elasticity to demand, and production cost is also a function of demand. Theproposed model is formulated and solved in a form of geometric programming. For the secondand the third models, we consider VMI problem with two buyers and two suppliers assumingthat each buyer centre is relatively close to the other buyer centre. Each supplier has only oneproduct which is different from the product of the other supplier. Two suppliers cooperate incustomer relationship management and two buyers cooperate in supplier relationshipmanagement as well, so the suppliers send the orders of two buyers by one vehicle,simultaneously. For the third model, an additional assumption which is practically applicableand reasonable is considered. For all the proposed models, the optimal solution is comparedwith the traditional one. We demonstrate the implementation of our proposed models usingsome numerical examples.

    2016-07-01

    Full Text Available The focus in the article is on the issues of valuation and presentation of the inventories under the meaning on the International Accounting Standard 2 Inventories. The Standard provides guidance on the determination of costs of finished products and its recognition as and expense in the production and sale finished products, including guidance for determination of the net realizable value. The latter is defined as the estimated selling price less the estimated costs of completion and estimated costs necessary to make the sale. The cost of inventories comprises all costs of purchase, cost of conversion and other costs incurred in bringing the inventories to a condition suitable for subsequent use. The amount of the cost for materials used or products sold and the finished product is determined using one of the following methods: a specifically defined value, first-in � first out or weighted average cost of lots delivered. When inventories are sold, the carrying amount of those inventories is recognized as an expense in the period in which the related sales revenue is recognized. The amount of any write-down of inventories to net realizable value is recorded as a current expense and is recognized as an expense in the period the write-down occurs.

  20. Stochastic Reliability Measurement and Design Optimization of an Inventory Management System

    Directory of Open Access Journals (Sweden)

    Abdulaziz T. Almaktoom

    2017-01-01

    Full Text Available Inventory management systems and dynamic reliability measures and controls remain challenging at every stage, especially when time variances and operating conditions are considered. An inventory management system must maintain its adeptness over time while coping with the uncertainty of inventory flow. Unexpected delays during inventory movement can harm the reliability and robustness of the entire system. This paper introduces a method of quantifying the reliability of an inventory management system. Also, a novel, reliability-based robust design optimization model has been developed to optimally allocate and schedule time while considering uncertainty associated with inventory movement. The processes involved include purchasing, shipping, receiving, tracking, warehousing, storage, and turnover. A case study of a furniture company in Saudi Arabia is presented to demonstrate the efficacy of the model.

    The vast amount of archaeological data and information that is systematically accumulated in the Israel Antiquities Authority database, has not yet been transformed into a tool for heritage management, i.e. accessible knowledge of the sites' cultural significance and risk assessment that is needed to support wise decision making regarding its future. As a response, a pilot project for developing an inventory for the archaeological heritage management was launched. A basic ESRI ArcGIS Online system was developed as a prototype, following the categories recommended in international standards for documentation. Five field surveys implementing the GIS system were conducted to examine different aspects and workflows: ancient synagogues in the Galilee, sites at risk, mosaics in Tel Shiqmona, the ancient settlement of Huqoq and sites included in The National Master Plan for Forests and Afforestation. The pilot project revealed the main gaps in knowledge and the critical faults in the working procedures. In spite of the systems' technological limitations, the results were convincing enough to promote a multidisciplinary discussion about the need for integration of significance and risk assessment in the working processes of the organization.

    Edens, J F; Buffington, J K; Tomicic, T L; Riley, B D

    2001-06-01

    The Psychopathic Personality Inventory (PPI; S. O. Lilienfeld & B. P. Andrews, 1996) is a self-report test that has shown considerable promise as a screening measure for psychopathy. A current limitation of the PPI is that no data exist regarding the impact of response sets such as positive impression management. Although the PPI contains a validity scale (Unlikely Virtues) designed to identify response biases such as "faking good," its utility has not yet been assessed. In this study a repeated measures analogue design was employed in which 186 respondents completed the PPI both under standard conditions and with specific instructions to create a favorable impression of themselves. In the "fake good" condition, participants were able to appear significantly less psychopathic, with those who obtained higher scores in the standard instruction condition showing the largest decreases in their PPI scores. Receiver Operating Characteristic analyses indicated that, although the Unlikely Virtues scale significantly differentiated between "fake good" and honest protocols (area under the curve = .73), a considerable number of misclassifications occurred. The clinical and forensic implications of these findings are discussed.

    Augmentative and alternative communication (AAC) promotes communicative participation and language development for young children with complex communication needs. However, the motor, linguistic, and cognitive demands of many AAC technologies restrict young children's operational use of and influence over these technologies. The purpose of the current study is to better understand young children's participation in programming vocabulary "just in time" on an AAC application with minimized demands. A descriptive study was implemented to highlight the participation of 10 typically developing toddlers (M age: 16 months, range: 10-22 months) in just-in-time vocabulary programming in an AAC app with visual scene displays. All 10 toddlers participated in some capacity in adding new visual scene displays and vocabulary to the app just in time. Differences in participation across steps were observed, suggesting variation in the developmental demands of controls involved in vocabulary programming. Results from the current study provide clinical insights toward involving young children in AAC programming just in time and steps that may allow for more independent participation or require more scaffolding. Technology designed to minimize motor, cognitive, and linguistic demands may allow children to participate in programming devices at a younger age.

    1982-04-26

    Four alternative theories of oil inventory management and their implication for the level of private petroleum stockpiling are explored. The assumptions made were: that the product market for oil is competitive and that the capital market through which investments in oil stockpiles are financed is efficient. It is assumed that these conditions are expected to prevail even in the event of a supply interruption. These assumptions constitute the benchmark theory of oil inventory management. Variations on this theme provide the alternative theories of inventory behavior explored.

    Full Text Available This study examines inventory management practices of flour milling manufacturing firms and their effects on operational performance. Five flour milling manufacturing firms in Lagos were used for this study. Structured questionnaire was the major instrument for the collection of relevant primary data while descriptive statistics such as mean and standard deviation was deployed to analyzing the data gathered. The results obtained showed that exception of the large manufacturing companies, most of the medium-sized flour milling firms adopts different inventory management strategies from the scientific and best practice models. Their inventory management strategies and policies were rather based on factors such as changing level of customer demand, prevailing industry practices, forecast estimates and guesses, and available production capacity. Findings also revealed significant differences between the effective management of inventory and optimal operating performance. For instance, while firms that adopt best practice inventory management approaches reported efficiency in capacity utilization, increased service level, and reduced lead time, others with different strategies had minimal utilization of material resources. There is need for flour manufacturing firms to implement scientific inventory management models to adequately handle material shortages, product stock outs situations, component pile up and their associated penalties.

    Full Text Available This research underlines the urgency of real-time stock replenishment control system for distributors using vendor-managed inventory. It is valuable in improving corporate performance in lowering inventory cost as well as making better customer service due to the cut made in ordering cycle. The system produces real-time information on stock available at the retailing stores. Stock replenishment can then be done by the distributor at the right time. Using Short Message Service (SMS as a one-way information channel from retailers to their distributor, the data of every transaction of the supervised item are processed by a rule-based forward-chaining inference system to determine the item’s availability in stores. Folowing steps in Rapid Application Development (RAD, the construction of this system takes place through business modeling, data modeling, process modeling of VMI system, then the application is generated and tested as a prototype. The results are: the stock replenishment control system are able to make transactional data at the stores transparent to the distributor, facilitating the continuation in stock delivery. System architecture reduces the time needed to access information about sales on supervised item by using SMS shortcut. This control system developed in stores can be operationally independent from the retailing systems. Rule-based forward-chaining inference technique processes facts on stock variations, resulting in stock replenishment notification such as normal, reserve, and depleted warning.

    The purpose of this study was to develop an inventory control system achievement test that measures cognitive achievement of students in a foodservice management information systems course. We developed a table of specifications for inventory control systems that included the following content areas: receiving, storing, issuing, inventory control, inventory valuation, and inventory control computer systems. We composed 114 test items in a multiple-choice format on the basis of the table of specifications. A sample of 105 students responded to the test; each had previously received 3 hours of instruction on inventory control systems in a foodservice management information systems course. The 50 best items, judged on the basis of item-analysis data and adherence to the table of specification, were selected for the final form of the inventory control system achievement test. The 50-item test was reliable as indicated by a Kuder-Richardson 20 value of .84. The test may be used to evaluate individual student's achievement, to evaluate the effectiveness of instruction, and to compare achievement of different groups.

    This paper studies periodic review inventory systems in which replenishments are capacitated. This capacity restriction implies that the order-up-to level may not always be reached at each replenishment, such that additional safety stock is needed to achieve the same service level as in the uncapacitated case usually assumed in the existing literature. To determine the required level of safety stock, and hence the order-up-to level, an iterative procedure is proposed which can be adjusted to ...

    2010-11-01

    Full Text Available Vendor managed inventory (VMI is a supply chain initiative where the supplier assumes the responsibility for managing inventories using advanced communication means such as online messaging and data retrieval system. A well collaborated vendor manage inventory system can improve supply chain performance by decreasing the inventory level and increasing the fill rate. This paper investigates the implementation of vendor managed inventory systems in a consumer goods industry. We consider (r, Q policy for replenishing its inventory. The objective of work is to minimize the inventory across the supply chain and maximize the service level. The major contribution of this work is to develop a spreadsheet model for VMI system, Evaluation of Total inventory cost by using spreadsheet based method and Analytical method, Quantifying inventory reduction, Estimating service efficiency level, and validating the VMI spread sheet model with randomly generated demand. In the application, VMI as an inventory control system is able to reduce the inventory cost without sacrificing the service level. The results further more show that the inventory reduction obtained from analytical method is closer to the spread sheet based approach, which reveals the VMI success. However the VMI success is impacted by the quality of buyersupplier relationships, the quality of the IT system and the intensity of information sharing, but not by the quality of information shared.

    In spare parts industries, firms are dealing with a situation which is more and more uncertain due to the supply chain structure and variable demands. This paper presents a Bayesian approach to forecast demand and subsequently determine the appropriate parameter S of an (S - 1; S) inventory system for controlling plant spare parts. We apply the Bayesian approach in an innovative way to specify the initial prior distributions of the failure rates, using the initial estimates and the failure history of similar items. According to the proposed method, a lower base stock than the one currently used is sufficient to achieve the desired service level.

    O' Kula, K.R.; Lux, C.R.; Clements, J.A.

    2000-07-01

    The US Department of Energy Complex contains many laboratories that require inventory management and control of large stores of radionuclides. While the overall quantities of radionuclides are bounded by Authorization-Basis (AB) documents, the spatial distribution may change rapidly according to facility experimentation and storage limits. Thus, the consequences of postulated accident events may be difficult to quantify as the location of radiological species becomes uncertain. Furthermore, a situation of this nature may be compounded by management of fissile materials in the same laboratory. Although radionuclide inventory management, fissile material control, and compliance with AB limits may be handled individually, a systematic and consistent approach would be to integrate all three functions. A system with these characteristics, an upgraded Radionuclide Inventory and Administrative Control (RI-AC) System, has been implemented for the Savannah River Technology Center (SRTC) located on the Savannah River Site (SRS), and is summarized in this paper.

  7. Buoyed by geophysics : geophysics, just-in-time procurement help save millions on Ekwan pipeline buoyancy control

    Energy Technology Data Exchange (ETDEWEB)

    Roche, P.

    2005-09-01

    Large-diameter natural gas pipelines buried in wet muskeg have the potential to rise to the surface due to buoyancy. Until recently, the most reliable method to prevent this was to attach specially manufactured bolt-on concrete weights at closely spaced intervals. However, these weights significantly increase capital budgets by millions of dollars because each weight weighs 2,540 kg and costs $1,000. A less costly alternative for buoyancy control in shallow muskeg is for the contractor to simply dig a deeper ditch. Another option is to hold down the pipeline by polyester straps attached to screw anchors. The challenge of applying these less costly options is that heavy equipment cannot be brought to the site to determine ground conditions until after all procurement, assessment and design is completed. Engineers must therefore select a buoyancy control measure based only on air photos and possibly a few drill holes. However, air photos do not indicate the depth of muskeg. Although some muskeg areas may turn out to be thick enough to avoid buoyancy control altogether, once construction is underway, it is too late to opt for cheaper alternatives. EnCana Corporation's 24-inch Ekwan pipeline was recently constructed through a remote area of British Columbia to connect the Greater Sierra natural gas discovery to a tie-in point on Nova Gas Transmission's northwest mainline. Air photos indicated that half of the route was through muskeg. AMEC E and C Services Inc. was responsible for the engineering and management of the project. The company used a combination of geophysical techniques to learn about the ground conditions. Toboggan mounted portable equipment was hauled by snowmobiles along trails made earlier by the survey crews. Ground penetrating radar assessed the muskeg thickness. Fixed frequency electromagnetic surveys also enhanced the results of the ground penetrating radar. The number of bolt-on weights was reduced from 9,000 to 3,700, a savings of $3

  18. Inventory management performance in machine tool SMEs: What factors do influence them?

    Directory of Open Access Journals (Sweden)

    Rajeev Narayana Pillai

    2010-12-01

    Full Text Available Small and Medium Enterprises (SMEs are one of the principal driving forces in the development of an economy because of its significant contribution in terms of number of enterprises, employment, output and exports in most developing as well as developed countries. But SMEs, particularly in developing countries like India, face constraints in key areas such as technology, finance, marketing and human resources. Moreover these SMEs have been exposed to intense competition since early 1990s because of globalization. However, globalization, the process of continuing integration of the countries in the world has opened up new opportunities for SMEs of developing countries to cater to wider international market which brings out the need for these SMEs to develop competitiveness for their survival as well as growth. It is observed from literature that pursuing appropriate IM practice is one of the ways of acquiring competitiveness among others, by effectively managing and minimizing inventory investment. Inventory management can therefore be one of the crucial determinants of competitiveness as well as operational performance of SMEs in inventory intensive manufacturing industries. The key issue is whether Indian SMEs pursue better IM practices with an intension to reduce their inventory cost and enhance their competitiveness. If so, what are the IM practices pursued by these enterprises? What are the factors which influence the inventory cost and IM performance of enterprises? These questions have been addressed in this study with reference to machine tool SMEs located in the city of Bangalore, India.

    correlate with the apheresis yields. These are, in turn, predictive of the speed of haemopoietic recovery after transplantation, which has helped establish the adequate cell dose for transplantation. Following collection, PBSC may be transfused unmanipulated, processed to select specific cell subtypes, or stored for future use. Cryopreservation techniques allow long term storage of stem cells without significant loss of viability. Increasingly demanding calls for safety led to introduction of vapour phase storage, separate storage of infected material, and mandatory quality control measures at all stages of the cryopreservation process and subsequent thawing and transfusion. At the same time, safety of the personnel working in stem cell processing and storage laboratories is safeguarded by a set of regulations devised to minimize the risk of infection, injury or hypoxia. Requirements for quality and safety have been shaped into a number of documents and directives in Europe and USA, emphasising the importance of product traceability, reporting of adverse reactions, quality management systems (standard operating procedures, guidelines, training records, reporting mechanisms and records, requirements for cell reception, quarantine, process control, validation and storage. Establishments that collect, process and store stem cells must be accredited or licensed by appropriate national or international authorities on a regular basis. These regulatory measures have recently become law across the European Union.

  17. A Fuzzy Parallel Processing Scheme for Enhancing the Effectiveness of a Dynamic Just-in-time Location-aware Service System

    2014-04-01

    Full Text Available Location-aware service systems are a hot topic in diverse research fields including mobile commerce, ambient intelligence, remote sensing and ubiquitous computing. However, the timeliness and efficiency of such systems are two issues that have rarely been emphasized. For this reason, this study tries to establish a location-aware service system in which both the timeliness and efficiency of service provision are addressed. To this end, some innovative treatments have been used in the proposed methodology. First, the uncertainty of detecting a user’s location using the global positioning system is considered by modeling the location and speed of the user with fuzzy numbers. Subsequently, a fuzzy integer-nonlinear programming model is formulated to address the problem of finding the dynamic just-in-time service location and path for the user. To help solve the problem, the maximum entropy weighting function and the basic defuzzification distribution (BADD method are applied to defuzzify the fuzzy variables. In addition, to enhance the efficiency of solving the problem, a fuzzy parallel processing scheme is also proposed for decomposing the problem into smaller pieces that can be handled by separate processing modules. An illustrative example is used to illustrate the proposed methodology. Finally, the effectiveness of the proposed methodology has been confirmed with an experiment. According to the results, using the proposed methodology the waiting time could be reduced by 60%.

    2015-01-01

    Full Text Available Background: In the aftermath of the 2010 earthquake in Haiti, St. Luke Hospital was built to help manage the mass casualties and subsequent cholera epidemic. A major problem faced by the hospital system was the lack of an available and sustainable supply of medications. Long-term viability of the hospital system depended largely on developing an uninterrupted medication supply chain. Objective: We hypothesized that the implementation of a new Pharmacy Computerized Inventory Program (PCIP would optimize medication availability and decrease medication shortages. Design: We conducted the research by examining how medications were being utilized and distributed before and after the implementation of PCIP. We measured the number of documented medication transactions in both Phase 1 and Phase 2 as well as user logins to determine if a computerized inventory system would be beneficial in providing a sustainable, long-term solution to their medication management needs. Results: The PCIP incorporated drug ordering, filling the drug requests, distribution, and dispensing of the medications in multiple settings; inventory of currently shelved medications; and graphic reporting of ‘real-time’ medication usage. During the PCIP initiation and establishment periods, the number of medication transactions increased from 219.6 to 359.5 (p=0.055, respectively, and the mean logins per day increased from 24.3 to 31.5, p<0.0001, respectively. The PCIP allows the hospital staff to identify and order medications with a critically low supply as well as track usage for future medication needs. The pharmacy and nursing staff found the PCIP to be efficient and a significant improvement in their medication utilization. Conclusions: An efficient, customizable, and cost-sensitive PCIP can improve drug inventory management in a simplified and sustainable manner within a resource-constrained hospital.

    2012-12-01

    Full Text Available Purpose: The purpose of this paper is to propose a heuristic for the inventory management of smart vending machine systems with product substitution under the replenishment point, order-up-to level policy and to evaluate its performance.Design/methodology/approach: The heuristic is developed on the basis of the decoupled approach. An integer linear mathematical model is built to determine the number of product storage compartments and replenishment threshold for each smart vending machine in the system and the Clarke and Wright’s savings algorithm is applied to route vehicles for inventory replenishments of smart vending machines that share the same delivery days. Computational experiments are conducted on several small-size test problems to compare the proposed heuristic with the integrated optimization mathematical model with respect to system profit. Furthermore, a sensitivity analysis is carried out on a medium-size test problem to evaluate the effect of the customer service level on system profit using a computer simulation.Findings: The results show that the proposed heuristic yielded pretty good solutions with 5.7% error rate on average compared to the optimal solutions. The proposed heuristic took about 3 CPU minutes on average in the test problems being consisted of 10 five-product smart vending machines. It was confirmed that the system profit is significantly affected by the customer service level.Originality/value: The inventory management of smart vending machine systems is newly treated. Product substitutions are explicitly considered in the model. The proposed heuristic is effective as well as efficient. It can be easily modified for application to various retail vending settings under a vendor-managed inventory scheme with POS system.

    Schinka, Kinder, and Kremer developed "validity" scales for the Revised NEO Personality Inventory (NEO PI-R; Costa & McCrae) to detect underreporting-the Positive Presentation Management (PPM) Scale and overreporting-the Negative Presentation Management (NPM) Scale. In this investigation, the clinical utility of these scales was examined using the established validity scales from the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher et al.) as the referent. The sample was composed of 370 psychiatric patients who completed the NEO PI-R and the MMPI-2 as part of a routine evaluation. Results indicated that response distortion compromised the utility of the NEO PI-R domain scales. Moreover, the PPM and NPM scales and an NPM-PPM index significantly differentiated invalid under-and overreporting groups from a valid responding group. The PPM and NPM-PPM index were adequate in classifying under- and overreporters, respectively.

    Full Text Available This study aims to offer a model to apply the VMI to manage purchasing and inventory in the Brazilian footwear industry as this industry’s is inserted in a rising product diversity environment, with shorter product lifecycle while facing heavy, international competitive pressures. The model that is being proposed is also related to establishing minimum inventory levels and the ideal inventory replenishment cycle for industrial operations, and it also classifies materials according to their financial impact and to how critical their provision is. This research, which is defined as an exploratory and qualitative one, addresses a case study of a Brazilian footwear company to gather fundamental information associated with operations history, strategic operational characteristics in the purchasing area, and purchasing management systems, all performed by means of an in-depth interview. When data was analyzed, it showed that among the various materials used by a footwear company, the use of VMI would be needed for materials that were classified as being non-critical components and competitive components, that is, those with a low degree of uncertainty regarding to offer and both high and low financial impact, respectively.

    1997-12-31

    The author describes the program objectives of the National Center for RSM Recycle. Objectives include: investment recovery; active inventory management; consistent characterization; creation of a `virtual` scrapyard; development of economies of scale in processing and sales; encouragement of commercial participation; promotion of site reutilization; waste minimization and environmental stewardship. There are significant quantities of high value metals, often dispersed over scattered sites. Inventories need to be made, including material segregation by type and contamination, which will allow lotting of materials to meet possible demand or economics of scale for cost effective processing. This center is a unique approach to the problem, and allows access to advantages of economics of scale, provides a single point of focus for large customers, and can attract the use of multiple technologies to process the contaminated scrap.

    2015-01-01

    Full Text Available Choosing the suitable demand distribution during lead-time is an important issue in inventory models. Much research has explored the advantage of following a distributional assumption different from the normality. The Birnbaum-Saunders (BS distribution is a probabilistic model that has its genesis in engineering but is also being widely applied to other fields including business, industry, and management. We conduct numeric experiments using the R statistical software to assess the adequacy of the BS distribution against the normal and gamma distributions in light of the traditional lot size-reorder point inventory model, known as (Q, r. The BS distribution is well-known to be robust to extreme values; indeed, results indicate that it is a more adequate assumption under higher values of the lead-time demand coefficient of variation, thus outperforming the gamma and the normal assumptions.

  13. An Inventory-Theory-Based Inexact Multistage Stochastic Programming Model for Water Resources Management

    M. Q. Suo

    2013-01-01

    Full Text Available An inventory-theory-based inexact multistage stochastic programming (IB-IMSP method is developed for planning water resources systems under uncertainty. The IB-IMSP is based on inexact multistage stochastic programming and inventory theory. The IB-IMSP cannot only effectively handle system uncertainties represented as probability density functions and discrete intervals but also efficiently reflect dynamic features of system conditions under different flow levels within a multistage context. Moreover, it can provide reasonable transferring schemes (i.e., the amount and batch of transferring as well as the corresponding transferring period associated with various flow scenarios for solving water shortage problems. The applicability of the proposed IB-IMSP is demonstrated by a case study of planning water resources management. The solutions obtained are helpful for decision makers in not only identifying different transferring schemes when the promised water is not met, but also making decisions of water allocation associated with different economic objectives.

  14. A stochastic inventory management model for a dual sourcing supply chain with disruptions

    2010-03-01

    As companies continue to globalise their operations and outsource significant portion of their value chain activities, they often end up relying heavily on order replenishments from distant suppliers. The explosion in long-distance sourcing is exposing supply chains and shareholder value at ever increasing operational and disruption risks. It is well established, both in academia and in real-world business environments, that resource flexibility is an effective method for hedging against supply chain disruption risks. In this contextual framework, we propose a single period stochastic inventory decision-making model that could be employed for capturing the trade-off between inventory policies and disruption risks for an unreliable dual sourcing supply network for both the capacitated and uncapacitated cases. Through the developed model, we obtain some important managerial insights and evaluate the merit of contingency strategies in managing uncertain supply chains.

    Over the last years key stake holders in the healthcare sector have increasingly recognised evidence based medicine (EBM) as a means to improving the quality of healthcare. However, there is considerable uncertainty about the best way to disseminate basic knowledge of EBM. As a result, huge variation in EBM educational provision, setting, duration, intensity, content, and teaching methodology exists across Europe and worldwide. Most courses for health care professionals are delivered outside the work context ('stand alone') and lack adaptation to the specific needs for EBM at the learners' workplace. Courses with modern 'adaptive' EBM teaching that employ principles of effective continuing education might fill that gap. We aimed to develop a course for post-graduate education which is clinically integrated and allows maximum flexibility for teachers and learners. A group of experienced EBM teachers, clinical epidemiologists, clinicians and educationalists from institutions from eight European countries participated. We used an established methodology of curriculum development to design a clinically integrated EBM course with substantial components of e-learning. An independent European steering committee provided input into the process. We defined explicit learning objectives about knowledge, skills, attitudes and behaviour for the five steps of EBM. A handbook guides facilitator and learner through five modules with clinical and e-learning components. Focussed activities and targeted assignments round off the learning process, after which each module is formally assessed. The course is learner-centred, problem-based, integrated with activities in the workplace and flexible. When successfully implemented, the course is designed to provide just-in-time learning through on-the-job-training, with the potential for teaching and learning to directly impact on practice.

    Full Text Available Abstract Background Over the last years key stake holders in the healthcare sector have increasingly recognised evidence based medicine (EBM as a means to improving the quality of healthcare. However, there is considerable uncertainty about the best way to disseminate basic knowledge of EBM. As a result, huge variation in EBM educational provision, setting, duration, intensity, content, and teaching methodology exists across Europe and worldwide. Most courses for health care professionals are delivered outside the work context ('stand alone' and lack adaptation to the specific needs for EBM at the learners' workplace. Courses with modern 'adaptive' EBM teaching that employ principles of effective continuing education might fill that gap. We aimed to develop a course for post-graduate education which is clinically integrated and allows maximum flexibility for teachers and learners. Methods A group of experienced EBM teachers, clinical epidemiologists, clinicians and educationalists from institutions from eight European countries participated. We used an established methodology of curriculum development to design a clinically integrated EBM course with substantial components of e-learning. An independent European steering committee provided input into the process. Results We defined explicit learning objectives about knowledge, skills, attitudes and behaviour for the five steps of EBM. A handbook guides facilitator and learner through five modules with clinical and e-learning components. Focussed activities and targeted assignments round off the learning process, after which each module is formally assessed. Conclusion The course is learner-centred, problem-based, integrated with activities in the workplace and flexible. When successfully implemented, the course is designed to provide just-in-time learning through on-the-job-training, with the potential for teaching and learning to directly impact on practice.

    2012-01-01

      Education institutions now pay less attention on the inventory management in terms of repetitive management, irregular classification of inventory detail, incomplete accounting, and the small value proportion to the total asset value, slack enforcement of the stock taking system, in addition, worsened by the direct disbursement of daily expenditures, usually causing management prob-lems. The administrators of education institutions must plan the purchase and stock arrangement, establish a complete internal control system, and avoid the loss from poor inventory management. To improve the inventory management, the education institutions, under a normalized operating system, should introduce advanced information management modes such as ERP in time to realize all-dimen-sional, effective and centralized management in terms of personnel, properties, objects, purchase, utilization and stock; stop the leak with maximum efforts; and reduce the inventory.%  当前,学校对存货的管理不够重视,其表现是多头管理,存货明细分类不规范,核算不健全,价值仅占资产总价值较小的比例,存货盘点制度执行不严等方面,再加上随购随用部分可以直接列支,因而管理上容易出现问题。学校管理层必须对物品的订购、储存等做有计划的安排与管理,建立健全内部控制制度,避免因存货管理不当,给单位带来损失。在规范的操作体系下,应适时引进 ERP 等先进的信息化管理模式,这样将极大地实现学校人、财、物、购、用、存全方位科学高效集中管理,最大限度地堵塞漏洞,降低存货库存,使存货管理更上一个新台阶

    2012-03-01

    The new generation RFID-Radar system provides the function of detecting the targets' locations with the measurements of range and angle using a reader and an antenna array to transmit and receive the RF signals. It enhances the application value for RFID when combined with the geospatial information. In this study, an information system embedded with a plan coordinate detection function was developed using the spatial data provided by the RFID-Radar system, to expand the application of indoor locating and meet the inventory management requirements. The in-house developed management system can work for processing the measurements detected by the RFID-Radar system, calculating the target's location, checking the target's status and analyzing the target's movement occurring between the two detecting epochs through a designed GUI (graphical user interface). The system has been tested to show an internal precision of 0.76 m for locating, based on the stability test of the range and angle measurements, and effectively demonstrates the functions for detecting the target's movement and archiving the inventory's management information with a database.

    Maryam Alimardani

    2015-12-01

    Full Text Available Inventory control systems development is one of the most appealing issues of the supply chain management which have recently been studied by academicians and practitioners. In this paper, an inventory management framework and deterministic cost models within the context of this framework are structured for effective supply chain (SC in an agile environment. To do so, we propose a three-echelon multi-product SC including multiple suppliers, multiple manufacturing firms, and multiple retailers. Moreover, a fuzzy-ANP framework is employed to evaluate suppliers’ agility level and to elicit suitable suppliers aiming at achieving an agile network. To develop operational measures of SC flexibility, a cost structure is defined which captures some different operational cost factors including inventory holding, backordering, lost sell, and ordering costs. Furthermore, a hybrid metaheuristic algorithm is developed to tackle the computational complexity of a production-inventory planning task. Finally, numerical experiments validate the proposed solution methodology.

  6. Radio Frequency Identification Queuing & Geo-Location (RAQGEO): A spatial solution to inventory management at XYZ Logistics, Inc

    Science.gov (United States)

    Griffiths, Bradley Joseph

    New supply chain management methods using radio frequency identification (RFID) and global positioning system (GPS) technology are quickly being adopted by companies as various inventory management benefits are being realized. For example, companies such as Nippon Yusen Kaisha (NYK) Logistics use the technology coupled with geospatial support systems for distributors to quickly find and manage freight containers. Traditional supply chain management methods require pen-to-paper reporting, searching inventory on foot, and human data entry. Some companies that prioritize supply chain management have not adopted the new technology, because they may feel that their traditional methods save the company expenses. This thesis serves as a pilot study that examines how information technology (IT) utilizing RFID and GPS technology can serve to increase workplace productivity, decrease human labor associated with inventorying, plus be used for spatial analysis by management. This pilot study represents the first attempt to couple RFID technology with Geographic Information Systems (GIS) in supply chain management efforts to analyze and locate mobile assets by exploring costs and benefits of implementation plus how the technology can be employed. This pilot study identified a candidate to implement a new inventory management method as XYZ Logistics, Inc. XYZ Logistics, Inc. is a fictitious company but represents a factual corporation. The name has been changed to provide the company with anonymity and to not disclose confidential business information. XYZ Logistics, Inc., is a nation-wide company that specializes in providing space solutions for customers including portable offices, storage containers, and customizable buildings.

    2012-01-01

    Full Text Available Planning Operation subdivision at PT Pertamina has to generate supply decisions includingmain depot to supply, supply point and transportation mode. However, the variability inplanning a supply schedule renders the process of determining a supply decision asineffective. The last assessment on uncertainties was done at 2006 and has not beenconsidered during decision making process. On the other hand, the result of this researchindicates that the uncertainty level is too high to be ignored and the poor informationexchange between the regional offices and the head office decreases the Planning Operation’sability to create plans that covers the company condition. This paper proposes an appropriatesafety stock to withstand the uncertainties and a supply scheduling process that also considersuncertainties by using Monte-Carlo Simulation with random numbers to simulate the events inthe upcoming period.Key words: inventory management, distribution planning, managing uncertainties, montecarlosimulation

  16. Crowd-Sourcing Management Activity Data to Drive GHG Emission Inventories in the Land Use Sector

    Science.gov (United States)

    Paustian, K.; Herrick, J.

    2015-12-01

    Greenhouse gas (GHG) emissions from the land use sector constitute the largest source category for many countries in Africa. Enhancing C sequestration and reducing GHG emissions on managed lands in Africa has to potential to attract C financing to support adoption of more sustainable land management practices that, in addition to GHG mitigation, can provide co-benefits of more productive and climate-resilient agroecosystems. However, robust systems to measure and monitor C sequestration/GHG reductions are currently a significant barrier to attracting more C financing to land use-related mitigation efforts.Anthropogenic GHG emissions are driven by a variety of environmental factors, including climate and soil attributes, as well as human-activities in the form of land use and management practices. GHG emission inventories typically use empirical or process-based models of emission rates that are driven by environmental and management variables. While a lack of field-based flux and C stock measurements are a limiting factor for GHG estimation, we argue that an even greater limitation may be availabiity of data on the management activities that influence flux rates, particularly in developing countries in Africa. In most developed countries there is a well-developed infrastructure of agricultural statistics and practice surveys that can be used to drive model-based GHG emission estimations. However, this infrastructure is largely lacking in developing countries in Africa. While some activity data (e.g. land cover change) can be derived from remote sensing, many key data (e.g., N fertilizer practices, residue management, manuring) require input from the farmers themselves. The explosive growth in cellular technology, even in many of the poorest parts of Africa, suggests the potential for a new crowd-sourcing approach and direct engagement with farmers to 'leap-frog' the land resource information model of developed countries. Among the many benefits of this approach

  17. Construct the stable vendor managed inventory partnership through a profit-sharing approach

    Science.gov (United States)

    Li, S.; Yu, Z.; Dong, M.

    2015-01-01

    In real life, the vendor managed inventory (VMI) model is not always a stable supply chain partnership. This paper proposes a cooperative game based profit-sharing method to stabilize the VMI partnership. Specifically, in a B2C setting, we consider a VMI program including a manufacturer and multiple online retailers. The manufacturer provides the finished product at the equal wholesale price to multiple online retailers. The online retailers face the same customer demand information. We offer the model to compute the increased profits generated by information sharing for total possible VMI coalitions. Using the solution concept of Shapley value, the profit-sharing scheme is produced to fairly divide the total increased profits among the VMI members. We find that under a fair allocation scheme, the higher inventory cost of one VMI member increases the surplus of the other members. Furthermore, the manufacturer is glad to increase the size of VMI coalition, whereas, the retailers are delighted to limit the size of the alliance. Finally, the manufacturer can select the appropriate retailer to boost its surplus, which has no effect on the surplus of the other retailers. The numerical examples indicate that the grand coalition is stable under the proposed allocation scheme.

    Full Text Available Inventory control of deteriorating items constitutes a large part of the world’s economy and covers various goods including any commodity, which loses its worth over time because of deterioration and/or obsolescence. Vendor managed inventory (VMI, which is a win-win strategy for both suppliers and buyers gains better results than traditional supply chain. In this research, we study an economic order quantity (EOQ with shortage in form of partial backorder under VMI policy. The model is concerned with multi-item subject to multi-constraint including storage space, time period and budget constraints. Two metaheuristic algorithms, namely Simulated Annealing and Tabu Search, are used to find a near optimal solution for the proposed fuzzy nonlinear integer-programming problem with the objective of minimizing the total cost of the supply chain. Furthermore, the sensitivity analysis of the metaheuristic parameters is performed and five numerical examples containing different numbers of items are conducted in order to evaluate the performance of the algorithms.

    2016-07-01

    There has been interest concerning patient outcomes when older red blood cell (RBC) components are utilized. Inventory management is key to maintaining a stock of fresher RBCs for general transfusion needs. We have altered our practice for RBC management to reduce RBC age at the time of transfusion. Retrospective review of RBC age at time of transfusion at a tertiary care hospital with active trauma service was performed. The baseline nonirradiated RBC inventory was decreased from 12 to 15 days of stock to 7 to 10 days of stock, with request made to the blood supplier for fresher RBCs, specified at 75% of RBCs less than 14 days old. The age of RBCs at time of receipt and at time of transfusion was tracked on a monthly basis for the next 12 months. The mean age of RBCs at transfusion was decreased by 9 days on average for the year. Significant decreases in the mean age of RBCs at transfusion were seen in the second half of the year, with 4 of 6 months seeing a mean age of less than 20 days. There were no documented incidences of hospital blood shortages after the reduction in inventory; no surgery was canceled or delayed because of inventory. Inventory age depends on active management, combined with vendor cooperation to receive fresher components. Reducing the age of RBC components transfused is possible without experiencing blood component shortages. Longer periods of observation may allow for further adjustment of stocking levels on a seasonal basis. © 2016 AABB.

    Full Text Available This paper, considers the supplier selection in three echelon supply chain with Vendor Managed Inventory (VMI strategy under price dependent demand condition. As there is a lack of study on the supplier selection in VMI literature, this paper presents a VMI model in supply chain including multi supplier, one distributer and multi retailer that distributer selects suppliers. Two class models (traditional vs. VMI are presented and we compare them to study the impact of VMI on supply chain and supplier selection. As the proposed model is a NP-hard problem, a meta-heuristics namely Harmony Search is employed to optimize the proposed models. We show that how the VMI system can effect on supplier selection and can change the set of selected suppliers. Finally the conclusion and further studies are presented

    2016-02-01

    Full Text Available Vendor managed inventory (VMI is a program that has been recognized as one of the most successful practices that enhances supply chain improvement, integration and simplification. Effect of the time value of money on analytical VMI models has not been investigated in any previous studies. So in this paper, two echelon single-manufacture multi-retailer supply chain models under VMI program with and without considering the time value of money were extended. Using statistical hypothesis testing was inferred that the error due to ignoring the time value of money in this problem is significant. This demonstrates the importance of the time value of money in the determination of replenishment optimal policy under VMI system.

    2005-01-01

    The optimization policy of the purchase price and the profit under vendor managed inventory(VMI) is studied.For a salable product, supply chain mode of VMI is established, which is based on deterministic demand, having initial stock and having stock-out cost. With the further analysis of the mode, VMI is found to increase profits of the buyer in the short-term motivation. But VMI will reduce profits of the supplier under the matching condition. And in the shortterm motivation, VMI will increase the purchase price to compensate the transfer cost of the supplier. As a result, the foundation of theory is provided to implement VMI in the supply chain, and have some definituded project significance.

  5. A life cycle inventory tool for integrated waste management : a municipal focus

    Energy Technology Data Exchange (ETDEWEB)

    Mirza, R. [St. Lawrence Cement, Mississauga, ON (Canada)

    2000-07-01

    The value of a life cycle methodology in providing important information for municipal waste decision making was discussed. Life cycle models are tools designed to help municipalities evaluate the environmental performance of different elements of their existing and proposed waste management systems and to determine their sustainability. The use of life cycle models is predicted to increase as standardization for inventory is mandated and more reliable data becomes available. Also, life cycle models will be practiced more frequently as the impact of assessment methodologies becomes more evident in the future. The following specific environmental parameters were chosen for examination by a life cycle methodology model; energy consumption, greenhouse gas emissions, emissions of acid gases, emissions of smog precursors, air emissions of heavy metals, water emissions of heavy metals, biochemical oxygen demand (BOD), and residual solid waste. The functional unit used in the model is the user specified quantity and composition of waste generated in a given area.

  6. A dynamic programming-based particle swarm optimization algorithm for an inventory management problem under uncertainty

    Science.gov (United States)

    Xu, Jiuping; Zeng, Ziqiang; Han, Bernard; Lei, Xiao

    2013-07-01

    This article presents a dynamic programming-based particle swarm optimization (DP-based PSO) algorithm for solving an inventory management problem for large-scale construction projects under a fuzzy random environment. By taking into account the purchasing behaviour and strategy under rules of international bidding, a multi-objective fuzzy random dynamic programming model is constructed. To deal with the uncertainties, a hybrid crisp approach is used to transform fuzzy random parameters into fuzzy variables that are subsequently defuzzified by using an expected value operator with optimistic-pessimistic index. The iterative nature of the authors' model motivates them to develop a DP-based PSO algorithm. More specifically, their approach treats the state variables as hidden parameters. This in turn eliminates many redundant feasibility checks during initialization and particle updates at each iteration. Results and sensitivity analysis are presented to highlight the performance of the authors' optimization method, which is very effective as compared to the standard PSO algorithm.

    ERTS-1 resolution capabilities and repetitive coverage have allowed the acquisition of several statewide inventories of natural resource features not previously completed or that could not be completed in any other way. Familiarity with landform, tone, pattern and other converging factors, along with multidate imagery, has been required. Nevada's vegetation has been mapped from ERTS-1. Dynamic characteristics of the landscape have been studied. Sequential ERTS-1 imagery has proved its usefulness for mapping vegetation, following vegetation phenology changes, monitoring changes in lakes and reservoirs (including water quality), determining changes in surface mining use, making fire fuel estimates and determining potential hazard, mapping the distribution of rain and snow events, making range readiness determinations, monitoring marshland management practices and other uses. Feasibility has been determined, but details of incorporating the data in management systems awaits further research and development. The need is to accurately define the steps necessary to extract required or usable information from ERTS imagery and fit it into on-going management programs.

    The Somatic Complaints scale (SOM) and Conversion subscale (SOM-C) of the Personality Assessment Inventory perform best in classifying psychogenic non-epileptic seizures (PNES) from epileptic seizures (ES); however, the impact of positive impression management (PIM) and negative impression management (NIM) scales on SOM and SOM-C classification has not been examined. We studied 187 patients from an epilepsy monitoring unit with confirmed PNES or ES. On SOM, the best cut score was 72.5 T when PIM was elevated and 69.5 T when there was no bias. On SOM-C, when PIM was elevated, the best cut score was 67.5 T and 76.5 T when there was no bias. Negative impression management elevations (n=9) were too infrequent to analyze separately. Despite similarities in classification accuracy, there were differences in sensitivity and specificity with and without PIM, impacting positive and negative predictive values. The presence of PIM bias generally increases positive predictive power of SOM and SOM-C but decreases negative predictive power.

    Full Text Available Background: The automotive parts supply chain measures its success in terms of parts availability and stock required to achieve the availability target, measured as allocation fill rate (AFR. The supply chain strives to achieve an AFR target of 95.5% while maintaining low levels of stock.Objective: The first objective of this study is to evaluate the current inventory management approach, namely the maximum inventory position (MIP method, to understand the difference between the theoretical derivation and the actual implementation. The second objective is to develop and compare the performance of a new stock target setting (STS method relative to the MIP methods.Method: The theoretical and actual equations behind the MIP and STS methods are derived for steady state as well as stochastic conditions. A system dynamics simulation model (SDSM was developed to describe both the local and imported supply chains. The SDSM was used to simulate and confirm the parameters for the STS method. It was also used to compare the three inventory management methods against a theoretical environment and actual data sets.Results: The STS method requires a damping factor (DF to ensure it does not cause the bullwhip effect. The SDSM was used to determine that a value equal to the lead time ensures effective damping. In the theoretical environment, the MIPTheory method requires the lowest stock, but also has the lowest AFR. MIPActual achieves the highest AFR, but with significantly higher stock holding. The STS method improves on the AFR achieved by the MIPTheory method, with lower stock holding than the MIPActual method. With the actual demand data sets, the results vary by parts movement type. With fast moving parts, all methods achieve the AFR target, the MIPActual method has a higher stock holding for all cases, and the STS method results in reduced stock holding for 7 of 12 cases. With medium moving parts, the MIPActual method improves on the AFR in all 15 cases

    Full Text Available The Construction industry in Nigeria is made up of a wide variety of activities which include the provision of professional and technical services to clients in the built environment. Despite the provision of these services to a large number of clients worldwide, the construction industry is still awash by the chronic problems of low productivity, insufficient quality, time over-runs, and poor safety, which hinder customer delivered value. The Just-In-Time phenomenon is a characteristic of lean production systems which operate with very little “fat” (e.g. excess inventory extra workers, wasted space.This study aimed at assessing the construction management function of the quantity surveyor in line with the principle of lean methodology (Just-In-Time. This was achieved by exploring the cost management function of the quantity surveyor, to investigate the current practice of cost management by quantity surveying firms. Data for the study were sourced primarily with the use of questionnaire and the subsequent data analysis, which employed the use of descriptive analysis of presenting the data as obtained on tables during the field survey and attempts a rudimentary establishment of patterns using percentages. The study concluded amongst others, that: all activities involved in the cost management function of the quantity surveyor are important, and value adding, corresponding to conversion activities in line with the Just-In-time/lean methodology

  17. Analysing the effectiveness of vendor-managed inventory in a single-warehouse, multiple-retailer system

    Science.gov (United States)

    Rahim, Mohd Kamarul Irwan Abdul; Aghezzaf, El-Houssaine; Limère, Veronique; Raa, Birger

    2016-06-01

    This paper considers a two-stage supply chain, consisting of a single warehouse and multiple retailers facing deterministic demands, under a vendor-managed inventory (VMI) policy. It presents a two-phase optimisation approach for coordinating the shipments in this VMI system. The first phase uses direct shipping from the supplier to all retailers to minimise the overall inventory costs. Then, in the second phase, the retailers are clustered using a construction heuristic in order to optimise the transportation costs while satisfying some additional restrictions. The improvement of the system's performance through coordinated VMI replenishments against the system with direct shipping only is shown and discussed in the comparative analysis section.

  2. E-SCM AND INVENTORY MANAGEMENT: A STUDY OF MULTIPLE CASES IN A SEGMENT OF THE DEPARTMENT STORE CHAIN

    Directory of Open Access Journals (Sweden)

    Juliana Chiaretti Novi

    2011-08-01

    Full Text Available Inventory management through the supply chains is a theme that has always enticed managers throughout the world. Due to the increase in market competitiveness and complexity, the traditional statistical models of forecasting demand, based on time series, no longer met the needs imposed on businesses to maintain adequate levels of their inventory and supply interruptions. With the intent to meet these market demands, ERP systems appeared in the 1990’s. Nevertheless, even if allowing for a more adequate level of inventory and supply interruptions achieved mainly by the optimization of internal processes and the reduction in lead time, ERP systems did not contribute to reach the SCM’s desired levels of inventory that were aimed at by the more competitive businesses. This is because ERP limits itself to an internal analysis of the business. By contrast, inventory management depends on the consumption information (which is external to the business. Aiming to improve even further the level of services delivered to the end consumer, new solutions have been developed, among them the e- SCM, which, since it makes consumption information available in real time, ends up being more dynamic and efficient than the traditional demand forecasting models, Therefore, the present study aims to analyze how the e-SCM can collaborate in maintaining adequate levels of inventory and interruptions in the supply chains. The hypothesis made is that the traditional statistical forecasting models, based on time series and isolatedly, are no longer adequate to adjust the demand, as the tools based on these models do not update the demand in real time and this is fundamental in the current business dynamics. The research method used was the study of multiple cases in a segment of a chain involving a large retailer, its Distribution Center and a supplier of home appliances. For the analysis of the data, the content analysis technique was used. As main results, it was

  7. Vendor Managed Inventory: Why you need to talk to your supplier

    Directory of Open Access Journals (Sweden)

    Frederik Zachariassen

    2014-09-01

    Full Text Available Purpose The purpose of this paper is to investigate the concept of Vendor Managed Inventory (VMI from an inter-organisational perspective. Extant literature on VMI tends to investigate the concept from a focal perspective, even though VMI has originally been born as a collaborative arrangement. Design/methodology/approach The paper is based on a literature review and an empirical study. It provides a comprehensive literature review on VMI and an illustrative case study of a supplier and a buyer jointly implementing VMI. Findings The findings of this paper are twofold. First, a literature review uncovers that contemporary research has delimited the analysis of VMI to a focal company perspective as current VMI cost models tend not to capture the picture of the complete supply chain. Second, it demonstrates through an illustrative case study that adoption of an inter-organisational approach to VMI is vital if companies are to optimize their buyer-supplier relationships. Research limitations/implications Future research should test the implications proposed in the empirical section, as this piece of research can be seen as exploratory case study research with the aim of analytical generalizations. Practical implications The inter-organisational VMI cost perspective in supply chains should be emphasized in purchasing departments since such a perspective significantly raises the awareness of the costs incurred in a supply chain. Originality/value Existing research has not explicitly focused on inter-organisational costs incurred by companies implementing VMI. This study seeks to bridge this research gap.

    2014-08-01

    Full Text Available One of the widely discussed collaborative practices in the literature is Vendor Managed Inventory (VMI, which gives supplier the freedom to take decisions regarding customer´s replenishment, allowing better production planning. Despite the efforts of many researches, few studies compare the reality faced by companies with theories in the literature. Thus, this research aims to analyze the VMI practice of a consumer goods supplier with its retail customer, based on the barriers that limit the potential results of the practice and also the critical factors for the success of VMI. Insights from this analysis resulted in some propositions for future studies. The literature review allowed the identification of elements that influence the adoption and maintenance of VMI that were grouped into behavioral, cultural and physical elements. The method used was a case study with in-depth interviews, which allowed identifying the elements that limit the potential gains of VMI in the analyzed company and also those ones that contribute to the success of the practice.

  16. Vendor Managed Inventory of a Single-vendor Multiple-retailer Single-warehouse Supply Chain under Stochastic Demands

    Directory of Open Access Journals (Sweden)

    Tahereh Poorbagheri

    2014-11-01

    Full Text Available In this study, a vendor-managed inventory model is developed for a single-vendor multiple-retailer single-warehouse (SV-MR-SV supply chain problem based on the economic order quantity in which demands are stochastic and follow a uniform probability distribution. In order to reduce holding costs and to help balanced on-hand inventory cost between the vendor and the retailers, it is assumed that all inventory is held at a central warehouse with the lowest cost among the parties. The capacity of the central warehouse is limited. The objective is to find the warehouse replenishment frequency, the vendor's replenishment frequency, the order points, and the order quantities of the retailers such that the total inventory cost of the integrated supply chain is minimized. The proposed model is a mixed integer nonlinear programming problem (MINLP; hence, a genetic algorithm (GA is utilized to solve this NP-hard problem. The parameters of the GA are calibrated using the Taguchi method to find better solutions. Some numerical illustrations are solved at the end to demonstrate the applicability of the proposed methodology and to evaluate the performance of the solution method.

  17. A simulation-based inventory management with genetic algorithm for uncertain demand for third-party logistics provider

    Directory of Open Access Journals (Sweden)

    Wuthichai Wongthatsanekorn

    2014-09-01

    Full Text Available This research aims to study and apply inventory management system for Third party logistics provider. Currently, the company uses economic order quantity to control inventory. The analysis of historical demand data shows that the demand is not deterministic. Hence, assumptions of using economic order quantity are violated. In this research, the simulation-based technique is applied to solve for optimal order quantity and reorder point. Since there are numerous items in the considered warehouse, ABC analysis is utilized to select important items to analyze. Then simulation and genetic algorithm are applied to find the optimal solution. Design of experiment with full factorial design is used to determine the best parameter setting of genetic algorithm. The performance measures are the average total inventory cost which composes of average ordering cost, average inventory holding cost and average lost sale cost. The results show that the average total cost for product code G2654, G2581, G0706, G2791 can be reduced by 73.43%, 49.86%, 28.50% and 13.38% respectively. For product code G2654, the average lost sale cost can be reduced by 85.30%. In summary, the solution from simulation and genetic algorithm provides better results than the one from economic order quantity method.

    Different types of managed aquifer recharge (MAR) schemes are widely distributed and applied on various scales and for various purposes in the European countries, but a systematic categorization and compilation of data has been missing up to now. The European MAR catalogue presented herein contains various key parameters collected from the available literature. The catalogue includes 224 currently active MAR sites found in 23 European countries. Large quantities of drinking water are produced by MAR sites in Hungary, Slovakia, the Netherlands, Germany, Finland, Poland, Switzerland and France. This inventory highlights that, for over a century, MAR has played an important role in the development of European water supply and contributes to drinking-water production substantially. This development has occurred autonomously, with "trial-and-error" within the full range of climatically and hydrogeologically diverse conditions of the European countries. For the future, MAR has the potential to facilitate optimal (re)use and storage of available water resources and to take advantage of the natural purification and low energy requirements during MAR operations. Particularly with respect to the re-use of wastewater treatment-plant effluent and stormwater, which is currently underdeveloped, the use of MAR can support the public acceptance of such water-resource efficient schemes. Particularly for the highly productive and urbanized coastal zones, where the pressure on freshwater supplies increases by growing water demand, salinization and increased agricultural needs for food production (such as along the Mediterranean and North Sea coasts), MAR is expected to be increasingly relied on in Europe.

This reflection is therefore an opportunity to integrate these aspects. The individualization of the therapeutic relationship in the theoretical framework of group analysis allowed the emotional investment in the person of the therapist, which is useful in the construction of a meaningful relationship on the human, emotional and cognitive plane; a space within which it has become increasingly possible for Sara, share and process emotions, re-build, contact parts of the self frustrated and disappointed, perceive less and less the void and become less vulnerable, being able to pull over to the original trauma.

  16. Coordination-based inventory management for deteriorating items in a two-echelon supply chain with profit sharing

    Science.gov (United States)

    Yu, Jonas C. P.; Lin, Yu-Siang; Wang, Kung-Jeng

    2013-09-01

    This study develops a model for inventory management consisting of a two-echelon supply chain (SC) with profit sharing and deteriorating items. The retailer and the supplier act as the leader and follower, in which the supplier faces a huge setup cost and economic order quantity ordering strategy. The market demand is affected by the sale price of the product, and the inventory has a deterioration rate following a Weibull distribution. The retailer executes three profit-sharing mechanisms to motivate the supplier to participate in SC optimisation and to extend the life cycle of the product. A search algorithm is developed to determine the solutions as using the profit-sharing mechanisms. The outcomes from numerical experiments demonstrate the profitability of the proposed model.

    Wu, Zhihui; Chen, Dongyan; Yu, Hui

    2016-07-01

    In this paper, the problem of the coordination policy is investigated for vendor-managed consignment inventory supply chain subject to consumer return. Here, the market demand is assumed to be affected by promotional effort and consumer return policy. The optimal consignment inventory and the optimal promotional effort level are proposed under the decentralized and centralized decisions. Based on the optimal decision conditions, the markdown allowance-promotional cost-sharing contract is investigated to coordinate the supply chain. Subsequently, the comparison between the two extreme policies shows that full-refund policy dominates the no-return policy when the returning cost and the positive effect of return policy are satisfied certain conditions. Finally, a numerical example is provided to illustrate the impacts of consumer return policy on the coordination contract and optimal profit as well as the effectiveness of the proposed supply chain decision.

  3. SEQUENCING DELIVERIES TO MINIMIZE INVENTORY HOLDING COST WITH DOMINANT UPSTREAM SUPPLY CHAIN PARTNER

    Institute of Scientific and Technical Information of China (English)

    Sushil GUPTA; Manoj VANAJAKUMARI; Chelliah SRISKANDARAJAH

    2009-01-01

    This paper studies a two stage supply chain with a dominant upstream partner. Manufacturer is the dominant partner and operates in a Just-in-Time environment. Production is done in a single manufacturing line capable of producing two products without stopping the production for switching from one product to the other. The manufacturer imposes constraints on the distributor by adhering to his favorable production schedule which minimizes his manufacturing cost. Distributor on the other hand caters to retailers' orders without incurring any shortages and is responsible for managing the inventory of finished goods. Adhering to manufacturer's schedule may lead to high inventory carrying costs for the distributor. Distributor's problem, which is to find an optimal distribution sequence which minimizes the distributor's inventory cost under the constraint imposed by the manufacturer is proved NP-Hard by Manoj et al. (2008). Therefore, solving large size problems require efficient heuristics. We develop algorithms for the distribution problem by exploiting its structural properties. We propose two heuristics and use their solutions in the initial population of a genetic algorithm to arrive at solutions with an average deviation of less than 3.5% from the optimal solution for practical size problems.

    Routh, R.; Singh, N.; Shah, P.

    2013-07-01

    In India, most of the inventories and documentations conducted for built heritage have been very nominal in nature and completely overlook the rich and opulent characters of the built form. This creates an imperative need of identifying and creating a detailed inventory of Interior Architecture (I.A.) Elements together with the SMCs and SSCs. This paper presents the process and the technique developed and termed as Real Time Visual Mapping (RTVM). RTVM is a procedure that incorporates the tablet survey, developed using open source tools, and is the first of its kind visual survey technique in India. The procedure comprises of an interactive form for mapping and helps manage the inventory generated from semi-urban and urban areas. The technique allows the user to transfer the mapped data in real time from the field, which can be produced through an interactive catalogue and map application. The recorded inputs reveal data ranging from type of elements to materials used, along with the various levels of traditional building crafts and expressions involved.

    The use of quantitative measurements for improving inventory management efficiency in hospital pharmacy is reviewed. Proper management of the pharmacy inventory affects the financial operation of the entire hospital. Problems associated with maintaining inadequate or excessive inventory investment are discussed, and the use of inventory valuation and turnover rate for assessing inventory control efficiency is described. Frequency of order placement has an important effect on inventory turnover, carrying costs, and ordering costs. Use of the ABC system of inventory classification for identifying products constituting the majority of inventory dollar investment is outlined, and the economic order value concept is explained. With increasing regulations aimed at controlling hospital costs, pharmacy managers must seek every possible means to improve efficiency. Reducing the amount of money obligated to inventory can substantially improve the financial position of the hospital without requiring a reduction in personnel or quality of service.

    This paper develops an economic order quantity model for non-instantaneous deteriorating items with and without shortages to investigate the performance of the vendor-managed inventory (VMI) system. This model is developed for a two-level supply chain consisting of a single supplier and single retailer with a single non-instantaneous deteriorating item. A numerical example and sensitivity analysis are provided to illustrate how increasing or reducing the related parameters change the optimal values of the decision variables of the two proposed models. The results show that VMI works better and charges lower cost in all conditions.

    Sixty adults in outpatient psychotherapy completed the NEO Personality Inventory--Revised (NEO PI-R, P. T. Costa & R. R. McCrae, 1992a). Half were instructed to fake good and half were given standard instructions. All completed the Interpersonal Adjective Scale--Revised, Big Five (J. S. Wiggins & P. D. Trapnell, 1997) under standard instructions, and their therapists completed the observer rating form of the NEO Five-Factor Inventory. A comparison group of 30 students completed the NEO PI-R under standard instructions. Standard and fake-good participants obtained significantly different NEO PI-R domain scores. Correlations between the NEO PI-R and criterion measures were significantly lower for faking than for standard patients. Validity scales for the NEO PI-R (J. A. Schinka, B. N. Kinder, & T. Kremer, 1997) were moderately accurate in discriminating faking from standard patients, but were only marginally accurate in discriminating faking patients from students.

    Full Text Available Purpose: The objective of this cross-sectional, noninterventional, 6-month observational study was to assess the adequacy of pain management in patients with cancer admitted to the Oncology Department of Guru Gobind Singh Medical College in Faridkot, India. Methods and Materials: A total of 348 patients with cancer were recruited for evaluation of the prevalence of inadequate cancer pain management using the Brief Pain Inventory Pain Management Index. Results: The current study included 127 males (36.5% and 221 females (63.5%. The most prevalent cancer type was genitourinary; 268 patients (77% had inadequately managed pain. A significant correlation was observed between poorly managed pain and age groups, analgesic used, and body mass index. Conclusion: Our observation of inadequate pain management among 77% of patients indicates that pain management was insufficient in three quarters of the patients in this study. Accumulating data regarding the inadequacy of cancer pain management is crucial to improve symptom management. Better management of pain not only alleviates pain symptoms but also increases the quality of life for patients with cancer.

  19. Life cycle inventory and mass-balance of municipal food waste management systems: Decision support methods beyond the waste hierarchy.

    Edwards, Joel; Othman, Maazuza; Crossin, Enda; Burn, Stewart

    2017-08-14

    When assessing the environmental and human health impact of a municipal food waste (FW) management system waste managers typically rely on the principles of the waste hierarchy; using metrics such as the mass or rate of waste that is 'prepared for recycling,' 'recovered for energy,' or 'sent to landfill.' These metrics measure the collection and sorting efficiency of a waste system but are incapable of determining the efficiency of a system to turn waste into a valuable resource. In this study a life cycle approach was employed using a system boundary that includes the entire waste service provision from collection to safe end-use or disposal. A life cycle inventory of seven waste management systems was calculated, including the first service wide inventory of FW management through kitchen in-sink disposal (food waste disposer). Results describe the mass, energy and water balance of each system along with key emissions profile. It was demonstrated that the energy balance can differ significantly from its' energy generation, exemplified by mechanical biological treatment, which was the best system for generating energy from waste but only 5(th) best for net-energy generation. Furthermore, the energy balance of kitchen in-sink disposal was shown to be reduced because 31% of volatile solids were lost in pre-treatment. The study also confirmed that higher FW landfill diversion rates were critical for reducing many harmful emissions to air and water. Although, mass-balance analysis showed that the alternative end-use of the FW material may still contain high impact pollutants. Crown Copyright © 2017. Published by Elsevier Ltd.

    In this paper, we present a simple microeconomic model with linear continuous-time dynamics that describes a production-inventory system with debt repayment. This model is formulated in terms of optimal control and its exact solutions are derived by prudent application of the maximum principle under different sets of initial conditions (scenarios). For a potentially profitable small firm, we also propose some alternative short-term control strategies resulting in a positive final profit and prove their optimality. Practical implementation of such strategies is also discussed.

  6. The Inventory System Management under Uncertain Conditions and Time Value of Money

    Directory of Open Access Journals (Sweden)

    Mehri Nasrabadi

    2016-05-01

    Full Text Available This study develops a inventory model to determine ordering policy for deteriorating items with shortages under markovian inflationary conditions. Markov processes include process whose future behavior cannot be accurately predicted from its past behavior (except the current or present behavior and which involves random chance or probability. Behavior of business or economy, flow of traffic, progress of an epidemic, all are examples of Markov processes. Since the far previous inflation rate don’t have a great impact on the current inflation rate, so, It is logical to consider changes of the inflation rate as a markov process. In addition, It is assumed that the cost of the items changes as a Continuous – Time - Markov Process too. The inventory model is described by differential equations over the time horizon along with the present value method. The objective is minimization of the expected present value of costs over the time horizon. The numerical example and a sensitivity analysis are provided to analyze the effect of changes in the values of the different parameters on the optimal solution.

  7. LQ optimal and reaching law-based sliding modes for inventory management systems

    Science.gov (United States)

    Ignaciuk, Przemysław; Bartoszewicz, Andrzej

    2012-01-01

    In this article, the theory of discrete sliding-mode control is used to design new supply strategies for periodic-review inventory systems. In the considered systems, the stock used to fulfil an unknown, time-varying demand can be replenished from a single supply source or from multiple suppliers procuring orders with different delays. The proposed strategies guarantee that demand is always entirely satisfied from the on-hand stock (yielding the maximum service level), and the warehouse capacity is not exceeded (which eliminates the cost of emergency storage). In contrast to the classical, stochastic approaches, in this article, we focus on optimising the inventory system dynamics. The parameters of the first control strategy are selected by minimising a quadratic cost functional. Next, it is shown how the system dynamical performance can be improved by applying the concept of a reaching law with the appropriately adjusted reaching phase. The stable, nonoscillatory behaviour of the closed-loop system is demonstrated and the properties of the designed controllers are discussed and strictly proved.

    The Isotope Production Facility (IPF) at Los Alamos is operated on the authorization basis of a radiological facility with an inventory limit of a Category 3 Nuclear Facility. For the commissioning of IPF, a ''dummy'' target stack containing Zn, Nb and Al disks, and a ''prototype'' stack were irradiated with a proton beam. The ''prototype'' stack contained two pressed RbCl disks, encapsulated in stainless steel, and a Ga metal target. Typical ''prototype'' stack beam parameters were 88.9 {micro}A, 101.3 h. Operation procedures require the projection of all generated radionuclide activities. This is mandatory in order to determine both maximum beam current and maximum beam exposure time. The Monte Carlo code MCNPX and the burn-up code CINDER90 were used to determine maximum beam parameters prior to irradiation. After irradiation, activity estimates were calculated assuming actual average beam parameters. They were entered into an online inventory database, and were later, after chemical separation and radioactive assays, replaced by experimental values. A comparison of ''prototype'' stack experimental yield data to Monte Carlo calculation results showed that the computer codes provide realistic, conservative estimates.

    We develop a global database of building inventories using taxonomy of global building types for use in near-real-time post-earthquake loss estimation and pre-earthquake risk analysis, for the U.S. Geological Survey's Prompt Assessment of Global Earthquakes for Response (PAGER) program. The database is available for public use, subject to peer review, scrutiny, and open enhancement. On a country-by-country level, it contains estimates of the distribution of building types categorized by material, lateral force resisting system, and occupancy type (residential or nonresidential, urban or rural). The database draws on and harmonizes numerous sources: (1) UN statistics, (2) UN Habitat's demographic and health survey (DHS) database, (3) national housing censuses, (4) the World Housing Encyclopedia and (5) other literature. ?? 2010, Earthquake Engineering Research Institute.

  13. Landslide inventory map as a tool for landscape planning and management in Buzau Land Geopark

    Science.gov (United States)

    Tatu, Mihai; Niculae, Lucica; Popa, Răzvan-Gabriel

    2015-04-01

    Buzău Land is an aspiring Geopark in Romania, located in the mountainous region of the southern part of the Carpathian Bend Area. From a geologic point of view, the East Carpathians represent a segment of the Alpine - Carpathian orogene, and they are composed of numerous tectonic units put up throughout the Mesozoic and Cenozoic orogenesis. They represent a result of two compressional phases, (1) during Late Cretaceous and (2) during Early and Middle Miocene that were responsible for thrusting of internal units onto external units. The latter cover tectonically the Foredeep folded deposits. Landslides are one of the most widespread and dangerous natural hazards in this region, disrupting access routes and damaging property and habitats at least twice per year, in the rainy seasons. This hazard induces deep changes in the landscape and has serious economic consequences related to the damaging of infrastructure and isolation of localities. The proximity to the Vrancea seismogenic zone increases the risk of landslide triggering. A first step in observing the space and time tendency and amplitude of landslides, in order to distinguish the main vulnerabilities and estimate the risk, is to produce an inventory map. We shall present a landslide inventory map for the Buzău Land territory (~1036 km2), which is the primary base of information for further discussions regarding this phenomenon and an essential tool in observing the development of mass-wasting processes and in landscape planning. The inventory map is in accordance with the recommendations of the IAEG Commission on Landslides and other Mass-Movement, applied across the EU. Based on this work, we can already draw some remarks: - The Geopark territory mostly covers two major tectonic units of the East Carpathians: the external nappes and the folded foredeep; areas with landslide potential are common, but by far the highest landslide frequency is observed in the foredeep. This is related to the soft, argillaceous

    2016-07-28

    A detailed inventory of irrigated crop acreage is not available at the level of resolution needed to accurately estimate agricultural water use or to project future water demands in many Florida counties. A detailed digital map and summary of irrigated acreage during the 2015 growing season was developed for 13 of the 15 counties that compose the Suwannee River Water Management District. The irrigated areas were delineated using land-use data, orthoimagery, and information obtained from the water management district consumptive water-use permits that were then field verified between May and November of 2015. Selected attribute data were collected for the irrigated areas, including crop type, primary water source, and type of irrigation system. Results indicate that an estimated 113,134 acres were either irrigated or had potential for irrigation in all or part of the 13 counties within the Suwannee River Water Management District during 2015. This estimate includes 108,870 acres of field-verified, irrigated crops and 4,264 acres of irrigated land observed as (1) idle (with an irrigation system visible but no crop present at the time of the field-verification visit), (2) acres that could not be verified during field visits, or (3) acres that were located on publicly owned research lands.

  17. Creating a Global Building Inventory for Earthquake Loss Assessment and Risk Management

    Science.gov (United States)

    Jaiswal, Kishor; Wald, David J.

    2008-01-01

    Earthquakes have claimed approximately 8 million lives over the last 2,000 years (Dunbar, Lockridge and others, 1992) and fatality rates are likely to continue to rise with increased population and urbanizations of global settlements especially in developing countries. More than 75% of earthquake-related human casualties are caused by the collapse of buildings or structures (Coburn and Spence, 2002). It is disheartening to note that large fractions of the world's population still reside in informal, poorly-constructed & non-engineered dwellings which have high susceptibility to collapse during earthquakes. Moreover, with increasing urbanization half of world's population now lives in urban areas (United Nations, 2001), and half of these urban centers are located in earthquake-prone regions (Bilham, 2004). The poor performance of most building stocks during earthquakes remains a primary societal concern. However, despite this dark history and bleaker future trends, there are no comprehensive global building inventories of sufficient quality and coverage to adequately address and characterize future earthquake losses. Such an inventory is vital both for earthquake loss mitigation and for earthquake disaster response purposes. While the latter purpose is the motivation of this work, we hope that the global building inventory database described herein will find widespread use for other mitigation efforts as well. For a real-time earthquake impact alert system, such as U.S. Geological Survey's (USGS) Prompt Assessment of Global Earthquakes for Response (PAGER), (Wald, Earle and others, 2006), we seek to rapidly evaluate potential casualties associated with earthquake ground shaking for any region of the world. The casualty estimation is based primarily on (1) rapid estimation of the ground shaking hazard, (2) aggregating the population exposure within different building types, and (3) estimating the casualties from the collapse of vulnerable buildings. Thus, the

Adequate planning for sustainable use of NTFPs is imperative so we explored the inventory of multipurpose trees and herbs that are being used as NTFPs in Chitwan, Nepal. 70 households from Sukranagar and Mangalpur VDCs of Chitwan district were randomly selected and personal interviews were taken with them as well as focus group discussions were done. The community had been utilizing 49 plant species from the nearby community forest. Implementation of the policy of community forestry was found to have a positive impact on the sustainable production of NTFPs. More than 80% of the respondents believed that indigenous knowledge promoted sustainable NTFP production. Kurilo (Asparagus officinalis was found to be the best NTFP for the study site. Various policy level reforms are proposed that will help in improving the sustainable production of NTFPs. Better utilization of NTFPs as well as their conservation is possible with proper trainings given to community forest users.International Journal of Environment Vol.5(3 2016, pp.87-103

    2009-10-01

    Full Text Available Objective: To describe chronic disease management programs active in Switzerland in 2007, using an exploratory survey. Methods: We searched the internet (Swiss official websites and Swiss web-pages, using Google, a medical electronic database (Medline, reference lists of pertinent articles, and contacted key informants. Programs met our operational definition of chronic disease management if their interventions targeted a chronic disease, included a multidisciplinary team (≥2 healthcare professionals, lasted at least six months, and had already been implemented and were active in December 2007. We developed an extraction grid and collected data pertaining to eight domains (patient population, intervention recipient, intervention content, delivery personnel, method of communication, intensity and complexity, environment, clinical outcomes. Results: We identified seven programs fulfilling our operational definition of chronic disease management. Programs targeted patients with diabetes, hypertension, heart failure, obesity, psychosis and breast cancer. Interventions were multifaceted; all included education and half considered planned follow-ups. The recipients of the interventions were patients, and healthcare professionals involved were physicians, nurses, social workers, psychologists and case managers of various backgrounds. Conclusions: In Switzerland, a country with universal healthcare insurance coverage and little incentive to develop new healthcare strategies, chronic disease management programs are scarce. For future developments, appropriate evaluations of existing programs, involvement of all healthcare stakeholders, strong leadership and political will are, at least, desirable.

  7. Service user involvement in risk assessment and management: the Transition Inventory.

    Kroner, Daryl G

    2012-04-01

    Drawing on self-prediction theory and the positive benefits of increasing health service user participation in risk assessments, the Transition Inventory (TI) was developed. It is an aid to the assessment of areas that people anticipate will be of difficulty in the next stage of transition, for example from open hospital to the community. The aim of this paper is to determine reliability and convergent/discriminant validity data for the TI and its subscales, including behavioral impulsivity, social pressure, substance misuse, financial/employment, leisure, negative affect, interpersonal and family concerns and social alienation. Eighty-eight male offenders coming towards the end of a period of imprisonment were asked to complete the TI. Their results were compared with the staff-rated Measures of Criminal Attitudes and Associates (MCAA) scale, alcohol blame and causation of crime items. Comparisons with the MCAA's antisocial intent scale, which is a future-orientated scale, and the associates scale allowed for convergent/discriminant validity to be examined with TI scales. With a community offender sample, TI results were used to predict researcher ratings. The TI scales demonstrated adequate internal consistency. Overall, the MCAA's antisocial intent scale had higher correlations with the TI than with a nonfuture-orientated scale. TI scales also demonstrated convergent validity with other measures and preliminary predictive validity with researcher ratings. The TI provides a way to increase service user involvement in the assessments that determine when and how they transfer to settings where they will have more independence.

    To characterize the impact of widespread inventory management policies on stock-outs of essential drugs in Zambia's health clinics and develop related recommendations. Daily clinic storeroom stock levels of artemether-lumefantrine (AL) products in 2009-2010 were captured in 145 facilities through photography and manual transcription of paper forms, then used to determine historical stock-out levels and estimate demand patterns. Delivery lead-times and estimates of monthly facility accessibility were obtained through worker surveys. A simulation model was constructed and validated for predictive accuracy against historical stock-outs, then used to evaluate various changes potentially affecting product availability. While almost no stock-outs of AL products were observed during Q4 2009 consistent with primary analysis, up to 30% of surveyed facilities stocked out of some AL product during Q1 2010 despite ample inventory being simultaneously available at the national warehouse. Simulation experiments closely reproduced these results and linked them to the use of average past monthly issues and failure to capture lead-time variability in current inventory control policies. Several inventory policy enhancements currently recommended by USAID | DELIVER were found to have limited impact on product availability. Inventory control policies widely recommended and used for distributing medicines in sub-Saharan Africa directly account for a substantial fraction of stock-outs observed in common situations involving demand seasonality and facility access interruptions. Developing central capabilities in peripheral demand forecasting and inventory control is critical. More rigorous independent peer-reviewed research on pharmaceutical supply chain management in low-income countries is needed.

  14. Urban air quality management using emission inventory estimates for three Indian cities: Faridabad, Lucknow and Pune.

    Science.gov (United States)

    Panwar, T S; Sharma, Sumit

    2012-10-01

    Urban air quality is an issue of major concern across many cities and towns in India. In particular, high levels of particulate matter (both suspended particulate matter (SPM) and respirable suspended particulate matter (RSPM)) are responsible for non-compliance against air quality standards. This paper analyses the status of air quality in the 16 most polluted Indian cities identified for priority action by the Hon'ble Supreme Court of India. Each city has its own unique problems depending on the nature of activities being undertaken. Thus, three cities, Pune, Lucknow, and Faridabad, which represent a top-ten urban agglomerate (based on population), a predominantly residential city and an industrial town are chosen for detailed analyses of the air quality problem. The causal factors for poor air quality are determined and sectoral emission loads are estimated for each city adopting a uniform approach that facilitates comparative evaluation. These provide an estimate of the major contributors to air pollution with specific reference to particulate matter, which is a major pollutant of concern. For each of these cities, an air quality management plan is suggested that specifically accounts for the contributing factors in each city. Further, quantitative estimates of the likely improvements due to implementation of some of the specific measures are also provided. An overall comparative assessment of the air quality issues across different cities can provide useful insights in the development of the management plan for the remaining cities as well.

    One of only two native, freshwater turtle species in the western United States, western pond turtles are declining in portions of their original range. Declines are mostly due to habitat loss, introduction of non-native species, pollution, and lack of connectivity among populations. USGS zoologist R. Bruce Bury and colleagues from the U.S. Forest Service, California State University, and other agencies compiled and edited a new review and field manual of this charismatic species. Objectives were to determine its current distribution and abundance, summarize and evaluate population features, review techniques to detect population and habitat changes, and improve monitoring for long-term trends. Methods described in the manual should improve consistency, efficiency, and accuracy of survey data, resulting in improved management and conservation efforts.

    The discovery of large reserves in the region called the pre-salt, significantly changed the environment of oil production in Brazil, as well as the entire chain involved in these activities. From the standpoint of logistics network linked to exploration and production of oil, located further down the coast at greater depths and in a place with no infrastructure in place, new and challenging problems arise: tighter restrictions need to address the problem at different levels hierarchical, requiring consideration of risks and uncertainties in addressing problems and decision making. The correct dimensioning of the network of support facilities, the allocation and sizing of inventory of supplies and spare parts illustrate a series of decisions ranging from strategic decisions to operational planning. In terms of specific operations involved in oil production in offshore platforms, with severe space constraints and high costs of storage and transport these issues are of particular interest. The objective of this work is to develop a model of inventory management, aiming to supply equipment for the extraction of oil at sea, usually called Production Units (UPs), which considers: effects of consolidating inventory, potential alternatives to location of these inventories and time variation of both the location of the UPs, and their demand patterns. For this purpose we developed a nonlinear mathematical programming model whose objective is to minimize the fixed costs of installation of warehouses and variable costs of transportation and storage. Different scenarios are analyzed to understand how the incorporation of the cycle and safety stocks affects the decision to locate one or more warehouses, and also the effects related to the main inventory allocation policies.

    Inventory control is one of the most important business processes during the operation of a trading or manufacturing company as it relates to purchases,sales and logistic activities.In order to have clear inventory management,a company should not only focus on logistic management but also on sales and purchase management. Commonly,we think of the warehouse as the most important component of inventory management and the accounting department is responsible for the inventory management. However,inventory control is not only the responsibility of the accounting department and the warehouse,but also the responsibility of the entire organization.Actually,there are many departments involved in the inventory control process,such as sales,purchasing, production,logistics and accounting.All these departments must work together in or- der to achieve effective inventory controls.

    Full Text Available Selection of an appropriate supplier along with planning a good inventory system has become an area of open research for the past few years. In this paper, we present a multi objective decision making supplier and inventory management model where two objectives including the quality and offering price of supplier are minimized, simultaneously. The proposed model is formulated as mixed integer programming and it is converted into an ordinary single objective function using Lp-Norm. In order to find efficient solution, we use NSGA-II as meta-heuristic technique and the performance of the proposed model is examined using some instances. The preliminary results indicate that both Lp-Norm and NSGA-II methods can be used to handle problems in various sizes.

    The area of the Swabian-Franconian cuesta landscape (Southern Germany) is highly prone to landslides. This was apparent in the late spring of 2013, when numerous landslides occurred as a consequence of heavy and long-lasting rainfalls. The specific climatic situation caused numerous damages with serious impact on settlements and infrastructure. Knowledge on spatial distribution of landslides, processes and characteristics are important to evaluate the potential risk that can occur from mass movements in those areas. In the frame of two projects about 400 landslides were mapped and detailed data sets were compiled during years 2011 to 2014 at the Franconian Alb. The studies are related to the project "Slope stability and hazard zones in the northern Bavarian cuesta" (DFG, German Research Foundation) as well as to the LfU (The Bavarian Environment Agency) within the project "Georisks and climate change - hazard indication map Jura". The central goal of the present study is to create a spatial database for landslides. The database should contain all fundamental parameters to characterize the mass movements and should provide the potential for secure data storage and data management, as well as statistical evaluations. The spatial database was created with PostgreSQL, an object-relational database management system and PostGIS, a spatial database extender for PostgreSQL, which provides the possibility to store spatial and geographic objects and to connect to several GIS applications, like GRASS GIS, SAGA GIS, QGIS and GDAL, a geospatial library (Obe et al. 2011). Database access for querying, importing, and exporting spatial and non-spatial data is ensured by using GUI or non-GUI connections. The database allows the use of procedural languages for writing advanced functions in the R, Python or Perl programming languages. It is possible to work directly with the (spatial) data entirety of the database in R. The inventory of the database includes (amongst others
