摘要

本篇論文在提出一套退化性整合式存貨模型在通膨影響下找尋出最佳存貨策略。截至目前文獻探討中，尚未發現有此存貨模型在相關領域上。因此，本存貨模型建立在固定供需期基礎上，從供應商採購、生產到零售商訂購加以探討，並透過一套求解流程，找尋出最佳供需運送次數和生產時間同時能讓整體上下游達到成本最小化，後續也會有一範例來驗證此套模型與求解流程和敏感度分析。經此範例結果，除了能提供給決策者有最佳參考外，敏感度分析上也反應出設置成本與訂購成本對總成本影響最為顯著。

This paper developed an integrated inventory model which incorporates the effects of the time value of money and deteriorating items to find the optimal inventory policy from vendor’s procurement to buyer’ ordering. However, far too little attention has been paid to this research area. Hence, an integrated inventory model with deteriorating raw material and product over the finite horizon planning under inflationary condition was proposed in this study. In addition, the solution procedure was also developed to derive the optimal number of shipments and production time, which minimizes the present worth of joint total cost. Furthermore, a detailed numerical example and sensitivity analysis were also illustrated in the discussion section. The result indicated that the most significant parameter impact on the present worth of total joint cost is setup and ordering cost.
