本文延伸 Kim and Ha (2003)模型，針對在JIT的環境下，供應商和買方協同合作，考量整合存貨模式，以訂購數量、每次訂購運送次數，及每次運送的運送數量為決策變數，並進一步考量多家買方的情形；且利用作業研究中的整數規劃方法改善傳統計量方法複雜的求解過程；延伸的模型能夠改善傳統模型僅能求得區域解的問題，並且能使用一般商用運算軟體求解，增加實務運用的方便。最後，透過範例驗證所提模型的實用性和正確性。

關鍵字：JIT製造系統、協同合作、多次運送、整合存貨模式

In order to reduce buyer-supplier coordination and inventory costs, this paper proposes a novel model, which is the extension of the Kim and Ha (2003) model. The proposed model integrates total relevant costs of both supplier and buyer to develop an optimal buyer-supplier coordination system in a JIT context. In the system, order quantity, the number of deliveries, and shipping quantity are decision variables. In addition, the proposed model can be used as a decision tool to help decision-maker to solve multiple buyers problem. For the purpose of the above-mentioned, we derive a mixed integer optimization approach to reduce the coordination and purchasing costs. The extended model improves the practical utility of the traditional model. Additionally, the decision maker can easily use common commercial program to solve such problems to obtain the global optimal solution. Finally, numerical examples are also included to demonstrate the usefulness and the correctness of the proposed model.

Keywords: Just-in-time manufacturing; buyer-supplier cooperation; frequent deliveries; integrated inventory model
