摘要

過去企業的優勢取得於自身競爭力的加強，因此皆是以個人的立場來考慮如何減少成本、增加利潤。但是今非昔比，單單只是提昇競爭力稍嫌不足，尚需要企業間的合作。因此在現今市場交易中常常看到的現象之一，就是製造商會提供給零售商一延遲付款期限，不需要立即付錢，於期限到時再付即可。且在期限內賣出的商品享有不需支付利息的好處，而對於製造商也會有吸引零售商購買其商品的好處。

本論文的目的是尋求零售商及製造商雙方在和諧的合作關係下，以一次訂購、多次運送且需求為固定及商品會損耗，再加上運送成本由零售商負責時，推導出一受延遲付款期限影響的供應鏈存貨模式。之後再延伸考慮通貨膨脹因素，亦即供應鏈存貨模式受到通貨膨脹的影響。

最後，將推導出的成本數學模式藉由程式語言的撰寫並搭配範例之相關參數，即可搜尋到聯合總成本的最佳解。再透過敏感度分析以了解各參數對存貨模式的影響。

Enterprises used to focus on individual performance to increase their competitiveness. They go about minimizing cost or maximizing profit from their own perspective. In modern market, the strategy is not enough to enhance their competitiveness. The cooperation among companies is vital in improving the effective of the supply chain. One of the phenomena in the cooperative business transactions is that retailers are allowed a grace period to pay back for the goods bought without paying any interest. During the grace period, the retailer doesn’t need to pay interest on goods held. For manufacturer, it has the benefit of attracting the retailer to purchase its goods in large batches.

The thesis develops a supply chain model for deteriorating items with permissible delay in payments in collaboration with the retailer and the manufacturer. A model is then developed to consider inflation and how it influences the model.

The objective of this study is to minimize the joint cost from the perspective of both the retailer and the manufacturer. Sensitivity analysis is carried out to see how these parameters influence the supply chain model .
