摘要

本研究探討單一買方與賣方，以及單一產品以EPQ為生產模式的二階供應鏈。在允許買家延遲付款的情況下，如何協調買賣雙方以最小化供應鏈系統總成本而互利雙方。本研究包括兩部分: 第一部分係將Luo and Zhang的模式擴展為EPQ生產模式，探討延遲付款對該模式的影響，並求解供應鏈系統的最佳延遲付款期間及最佳訂購量。第二部分則是進一步將EPQ生產模式擴展為允許分批運送，並考慮遞減型之分批運費結構，探討延遲付款對該模式的影響，並求解供應鏈系統的最佳延遲付款期間及最佳訂購量與運送批量。最後，透過例子說明以表明該模型的有效性。

In this thesis we consider the trade credit coordination mechanism in a two-echelon supply chain system with one single-vendor and one single-buyer. The vendor adopts the EPQ model to supply buyer, and the buyer makes its order decision based on the EOQ model. We develop a cost model to study the benefit of coordinating the supply chain system through the use of trade credit mechanism to create mutual benefits.
There are two parts in the thesis: First, we extend the model proposed by Luo and Zhang to an EPQ-based inventory model; we investigate the effect of trade credit coordination mechanism for the resulting model, and derive the optimal trade credit period and the optimal order quantity. Second, we further extend the EPQ-based inventory model to allow split-delivery. We also investigate the effect of trade credit coordination mechanism for the resulting model, and derive the optimal trade credit period and the optimal order quantity. An illustrative example is given to show the effectiveness of the model.
