The Kanban system in Just-In-Time (JIT) production is very effective in reducing the inventories when consumption rate of the final product is relatively stable. When large fluctuations exist in the consumption rate, a new production ordering policy in which the production order quantity is determined by smoothing the demands exponentially is more suitable. This new ordering policy has not been investigated sufficiently. In this research, a multi-stage production and inventory system with stock points for materials and finished items located at each stage is considered. Approximations of average inventories at each stage in the system are derived theoretically. Numerical simulations are carried out to assess the accuracy of approximations and to evaluate the effectiveness of the new ordering policy as compared with the Kanban system. As a result, it is shown that the new ordering policy can achieve significantly lower inventory costs than the original Kanban system. The new ordering policy thus emerges as a key concept for an effective supply chain management.

Location of stock in a warehouse directly affects the total materials handling expense of all goods moving through the warehouse. The purpose of this paper is to develop a storage policy in order picking warehouse, the block-based storage policy to minimize the total order picking time. In block-based storage policy, the rack is divided into blocks and items are assigned to each block based on the turn-over rate of each item and the average distance between the blocks and the dock. To demonstrate the performance of the proposed policy, we compare with the existing method called class-based storage policy under various matching methods.

University library must have a substantial collection development policy, by which the short and long term plannings are set up to meet the goals of university education and to support university function. Only when university library organizes collection building based on the well-planned policy, can it establish the systematic collection building, which can satisfy users, support continuity of work, use budget efficiently, and solve the space problem by with-drawing the materials. But most Korean university libraries, contrary to many foreign cases, don't have proper systematic collection development policy or guideline that controls overall library work from planning the collection of materials to evaluating and preserving them. Questionaire on whether university library has collection development policy or guideline was answered positively by only 6 cases out of 57 cases, which is just 10.5 percent. Even in cases that they have a guideline, the content of the copied guideline they sent was confined to acquisition, which is just a part of collection development. Collection development is a statement needed to set up long and short term plannings in consideration of the aims of the library and the needs of users and to shape and manage the library collection systematically. With the above conception and definition, we try to make a proper collection development policy and guideline for the Korean university libraries. Here we must define the object of the university. Object of university is to have good curriculum, good courses, research activities on the part of the faculty, enlargement of graduate school, and establishment of various institutes, etc. And in guideline, selector, method of selection, level of selection and arrangement of budget, etc. must be described concretely in its contents. Since collection development policy and guideline of Korean university libraries should concern their situation, we must confer with the result of the survey and analysis on the matter of collection determination. Here the contents include the priority of materials to be collected, method of collecting materials, arrangement of budget, and others. The purpose of this study is to develop a tenative collection development guideline in reference to the Jeonju University Library by means of analyzing the guiding principle, contents of the guideline, and present conditions of the Korean university libraries. The systematic collection development based on the Guideline for Collection Development of the Korean University Library, can offer a satisfactory service to the users of the university community, and also contribute to the development of the university itself as well as the university library.

This study developed the subject guide by policy areas for advancement of policy information service, designed the system for constructing the policy-related resources, and tried to construct policy information resources on a trial basis. For the development and construction of policy areas subject guide, first, we divided the aggregated materials into top 9 types, and subdivided into 19 types. Second, we constructed the policy contents for subject guide service, based on BRM classification system which is functional classification of government. Third, a total of 6,305 were build in accordance with 133 BRM subject guide. As a result, it is said that the effectiveness of the policy subject guide developed by this study, were verified by constructing the experimental data.

Background: Due to the asymmetry of information and knowledge and the power of bureaucrats and medical professionals, it is not easy for citizens to participate in health care policy making. This study analyzes the case of the insured organization participating in the Health Insurance Policy Committee (HIPC) and provides a basis for discussing methods and conditions for better public participation. Methods: Qualitative analysis was conducted using the in-depth interviews with the participants and document data such as materials for HIPC meetings. Semi-structured interviews were conducted with purposively sampled six participants from organizations representing the insured in HIPC. The meanings related to the factors affecting participation were found and categorized into major categories. Results: The main factors affecting participating in the decision making process were trust and cooperation among the participants, structure and procedure of governance, representation and expertise of participants, and contents of issues. Due to limited cooperation, participants lacked influence in important decisions. There was an imbalance in power due to unreasonable procedures and criteria for governance. As the materials for meetings were provided inappropriate manner, it was difficult for participants to understand the contents and comments on the meeting. Due to weak accountability structure, opinions from external stakeholders have not been well received. The participation was made depending on the expertise of individual members. The degree of influence was different depending on the contents of the issues. Conclusion: In order to meet the values of democracy and realize the participation that the insured can demonstrate influence, it is necessary to have a fair and reasonable procedure and a sufficient learning environment. More deliberative structure which reflects citizen's public perspective is required, rather than current negotiating structure of HIPC.

The Livestock Raw Material Purchase Fund is a policy to increase the export of livestock products by providing loans to exporters of livestock products (including byproducts). The policy started in 2015 and the annual budget is about 26 billion won. However, a quantitative evaluation of policy effects has not yet been made. Therefore, in this study, the economic surplus of the policy was analyzed using the equilibrium displacement model (EDM). From the results of the welfare analysis, from 2016 to 2019, producer surplus in the chicken and duck market increased by KRW 70.9 billion, while consumer surplus decreased by KRW 70 billion. In other words, the total economic surplus of the chicken and duck market increased by about one billion won during the same period due to the increase in export demand according to the policy. Therefore, the Livestock Raw Material Purchase Fund can be viewed as a policy to maintain and increase export demand for export livestock products and to improve the economic surplus of the livestock product market. Also, since the policy is based on loans, it does not place a burden on the government's finances. Therefore, this policy should continue in the future.

The reliability guarantee insurance policy for parts and materials was introduced to the market in 2003. This policy indemnifies manufactures of products for the repair/failure costs, recall expenses of products and business interruption losses found to be defective by users or demand companies during the terms of guarantee and after the user acquired physical possession of the product. In this paper, owing to the nature of the policy, we propose a new rate-making system considering the type of product and industry, quality control circumstances, record of guarantee performance, and exposure.

In this paper, we consider an integrated inventory system where a single supplier purchases and processes raw materials in order to deliver finished goods to a single buyer for effective implementation of Just-In-Time purchasing. An integrated JIT lot-splitting model of facilitating multiple shipments in small lots is developed in a JIT purchasing environment. Also, an iterative solution procedure is developed to find the order quantity for the finished goods and raw materials, and the number of shipments between buyer and supplier. We show by example that the integrated policy adopted by both buyer and supplier in a cooperative manner can provide them a greater economic benefit than seeking the local optimal inventory policy independently.
