摘要

現今競爭激烈的市場環境中，許多企業以策略整合的方式以降低成本。若只以單方的立場來考量，成本不會是整體之最佳化。唯有以共同的立場為考量，聯合成本才會是整體之最佳，雙方則可獲得最佳之長期利益。此外，傳統的EOQ模式假設了所有商品皆為良品，然而產品的品質與生產的製程之可靠度有關，所以可能會因為製程之損耗而產生了不良品。

本研究的主要目標為發展一個在JIT環境中，含不良品之單一供應商與多零售商之二階整合性存貨模式，此二階模式假設了生產過程中產生了一部份的不良品，利用數學軟體與程式之撰寫作為求取最佳解之工具，最後，以數學範例加以說明，透過敏感度分析以了解各參數對模式之影響。

In the current competitive market environment, the integration of companies especially in term of developing strategies is vital to reduce the overall cost of the enterprise. This is because decision made independently by one player will not result in global optimum. Global optimality will only be realized if the perspectives of all players are considered. Besides, the classical economic order quantity (EOQ) model assumes that items produced are of perfect quality. However, product quality is not always perfect but directly affected by the reliability of the production process used to produce the product. Therefore, the process may deteriorate and produce defectives or poor quality items.

The objective of this study is to develop a model that determines the optimal supplier-retailer inventory policy for flawed items in a just-in-time (JIT) manufacturing environment. The integrated two-stage inventory model is assumed to deteriorate during the production process and produce a certain number of defective items. A computer code is developed to derive the optimal solution. Numerical examples and sensitivity analyses are given to validate the results of the inventory model.
