Due to the complexity of part flow and limited resources, FMS(Flexible Manufacturing System) develops blocking, starvation and deadlock problems, which reduce its performance. In order to minimize such problems buffers are imposed between workstations of the manufacturing lines. In this paper, we are concerned with finding the optimal buffer allocation with regard to maximizing system throughput in limited total buffer capacity situation of FMS. A dynamic programming algorithm to solve the buffer allocation problem is proposed. Computer simulation using Arena is experimented to show the validation of the proposed algorithm.

Between different organization, they creat competitiveness from the result of their own manufacturing and sales activity especially the manufacturing companies. This paper will focus on the spot location strategy of korea company which have oversea business and find out the relationship between the spot location strategy and the resources or competitive ability of this kind of companies. Each company has their own way to realize their overseas business expansion and creat their competitiveness in their international business. At the same time, they also have their own way to share their resources and their competitive ability. All this 3 kinds of strategies are important and the combination of them is more important for companies that have overseas business. To examine the relationship between the spot location, the resources and the competitive ability strategies, this paper developed two hypotheses and tested them. To test the hypotheses, this paper conducted a mail survey to operations managers of overseas companies in Korea and collected 102 usable responses. To simplify the responses, this paper used cluster analysis and found 3groups of spot location strategy, 2 groups of resources strategy and 2 groups of competitive abilities strategy. This paper also investigated interdependence and performance differences between these groups. From the analyses, this paper found the following results: It is important for a overseas company to make their spot location strategy to be fit for their resources strategy and competitive abilities strategy and a perfect spot location strategy can make the company gain a advantage of high level in most of time.

This research empirically investigated the influence factors on the activation of environmental innovations (EI) in Korean manufacturing firms. In this study, external factors (compulsory demand, government regulation, normative pressure and imitative pressure) and internal factors (environmental resources, top management support, integration of environmental tasks, capabilities of environmental personnel, and environmental strategy/environmental management systems) were totally considered. The results of a multiple regression analysis showed that influence factors such as top management support, environmental resources and integration of environmental tasks have a significant and positive impact on levels of EI. However, the effects of external factors were not statistically significant. We also examined whether capabilities of environmental personnel as well as environmental resources, which are directly related with degrees of EI, have a moderating impact on relationships between other internal factors and levels of EI. With a subgroup analysis, the moderating role of abilities of environmental personnel were empirically confirmed. Through a multiple regression analysis, the direct effects of external factors on the adoption or construction of internal factors were demonstrated. The effects of government regulation, normative pressure and imitative pressure on internal factors were significant and positive. It was also found that external factors have indirect effects on EI through internal factors. Finally, the results of multiple regression analyses indicated that EI positively influences the achievement of environmental competitive benefits, and environmental competitive advantages can improve the organizational performance of a firm.

Remanufacturing is one alternative to conserve the good environment of our earth and to save the production resources and manufacturing energy. To make active remanufacturing in Korea we have to prepare basic rules to support the collaboration among the original manufacturing, remanufacturing, and repairing companies. Basic rules for active remanufacturing can be established by the analysis of recently environments of remanufacturing procedures and the relationship among the main constituents.
