Supply chain management issues faced by a manufacturing company are considered in this paper. The supply chain consists of a manufacturing company and its suppliers. The manufacturer produces multiple products with inputs (e.g., raw materials) from the suppliers, but each product needs a different mix of these inputs. The market demand for the products is uncertain. We develop a mathematical model and algorithm, which can help the manufacturer to solve its procurement decision problem: how much of raw material to order from which supplier. The model incorporates such factors as market demand uncertainty, product's input requirement, supplier's as well as manufacturer's capacity, plus other costs comparable with those in a typical newsboy problem. Numerical examples are presented to see the interacting effects among critical parameters and variables.

Recently, not only marine PLM (Product Lifecycle Management) system but also an effective outfitting BOM (Bill of Material) management has been attracted by many shipyards. In particular, efficient outfitting design is being one of major issues in shipyards since most of currently designed marine vessels have more complex outfitting system than ever. Furthermore, each outfitting system has huge number of parts that should be arranged based upon the procurement and installation plan. Outfitting BOMs evolve into different forms according to the product development phases during basic design; detail design; and production design. Therefore, it is very difficult to maintain a consistent BOM data during the design phases. In order to express the evolution of product structures and the information of outfitting along the ship design, we suggested UID (Unique ID) code system. The UID (Unique ID) is used in order to create the relationship within evolutional BOMs of each design stage. It utilizes as the procedure of weight calculation for procurement BOM during each design stage. Thereafter, in order to demonstrate suggested outfitting BOM management technique, we suggested a prototype. In the prototype system, suggested features of outfitting BOM are implemented.

Procurement system of public construction projects in Japan is changing with diversity in rapid pace. The quality assurance and risk management of construction projects should be more certain as the projects are turning into larger scale and more complexed. The clients in the public sector will want to make the relation of responsibility among the client, the designer (architects and engineers), and contractor clearer in terms of role and risk. Public-Private Partnership (PPP) is one of the methods for collaboration of the public sector and the private sector in public construction projects where the public utilizes the ability and suggestion of the private. Private Finance Initiative (PFI), Design-Build-Operate (DBO), market testing, designated manager system, outsourcing of tasks in local governments are well-known as examples of PPP in Japan. Indeed, there is an obvious trend that Design-Build (DB) is adopted in public construction projects in many countries including Japan. In this paper, the public construction projects in various procurement systems are surveyed and analyzed. They are not limited within the traditional procurement, Design-bid-Build, a separate order system of design and construction. Design-Build or PFI are adopted. In particular, contract by wide range including maintenance of equipment can be found. On the other hand, modification from originally typical PFI is taking place, such as concept design and project finance are removed from the roles and the tasks of the special purpose company (SPC) in PFI. Standard roles and tasks in a construction project are modeled in this paper.

A supply chain is a network of facilities and distribution options that performs the functions of procurement of materials, transformation of these materials into intermediate and finished products, and the distribution of these finished products to customers. SCM(Supp1y Chain Management), by definition, encompasses all activities associated with moving goods, from the raw materials stage through to the end user. It includes source and procurement, production scheduling, order processing, inventory management, transportation, warehousing, and customer service. Importantly, it encompasses the information systems used to monitor these activities. In this paper, the present situation and problems of marketing process in Korean agricultural environments were reviewed through a systematic methodology, and then we proposed a new business process for solving these problems by appling a supply chain management. We expect this supply chain management system applied to agricultural marketing process can improve significantly the rationality and transparency of Korean agricultural marketing structure.

Purpose: The purpose of this study is to identify key performance evaluation items and factors that are effective and practical for project management of defense standard standard improvement projects, and to develop a quantitative performance evaluation model. Methods: For the development of a performance evaluation model for defense standard improvement projects, we analyzed past major project performance and derived evaluation items and factors. To increase the objectivity and efficiency of project evaluation, we developed an evaluation index that enables relative evaluation of evaluation targets, and calculated the main importance of evaluation items using the Analytic Hierarchy Process (AHP) method based on the main opinions of expert groups. Results: The study resulted in the identification of main performance items for defense standard improvement projects, which were classified into defense standard conformity review performance and defense standard improvement performance items. We also simplified the evaluation model by integrating various evaluation items into similar evaluation factors. Additionally, we developed a quantitative evaluation index that enables relative evaluation of the targets and verified the objectivity and validity of the suggested performance evaluation model by reevaluating it using performance data from past commissioned professional institutions Conclusion: Developing a quantitative evaluation model for defense standard improvement projects is expected to provide a means of measuring the effectiveness of the project, and to be used as a tool to determine the appropriateness and effectiveness of medium and long-term project plans.

Traditional procurement methods have revealed many disadvantages in construction fields such as the adversarial relationships between stakeholders. After several decades of application, partnering has shown to be an innovative arrangement that helped to reduce many problems existing in the traditional arrangement. In Vietnam, partnering has been applied for construction projects since the construction industry was facing many new challenges emanated from the global integration and economic booming. Partnering is rather new, so it needs to gain a better understanding of the new concept. This paper has identified twenty eight success factors for partnering in the Vietnamese construction industry. Five factors are considered critical to partnering success including financial security, commitment from top management, mutual trust between parties, adequate resources and effective communication. The findings could help construction practitioners to deploy the innovative procurement type and would also contribute to the global knowledge.

Mediation has long been praised as one of effective dispute resolution methods in the area of construction law. Article 85-1 of the Taiwan Government Procurement Act was amended and promulgated by presidential decree on July 4, 2007. The second paragraph of the Article elaborates explicitly, "In the event that the application for mediation referred to in the preceding paragraph is made by the supplier, the agency may not object to such application." Beyond that, if an unsuccessful mediation of a construction dispute is due to the agency's disagreeing with the proposal or resolution for mediation proposed by the Complaint Review Board for Government Procurement ("CRBGP"), the agency may not object to the arbitration filed by the supplier. It undoubtedly reinforces the importance of the mediation-arbitration procedure. Accordingly, this paper elaborates on the mediation mechanism in Taiwan in the framework of construction disputes first. After that, dispute resolution of a local public work case is provided to demonstrate the practice of construction mediation in Taiwan. Lastly, this study proposes suggestions on applying mediation to ease similar subsequent cases.
