摘要

本研究主要探討在供應商允許預付－現金－信用交易的一般化交易條件下，建立一個考慮變動需求之退化性物品的存貨模型。在此模型中，假設需求率與物品在貨架上陳列水準以及銷售價格有關；另外，零售商也提供其顧客可以延遲付款的交易條件。本研究主要的目的是決定零售商最適的銷售價格、補貨期間長度及訂購量使得全年總利潤有最大值。進一步，我們建立一個演算法以方便求解，並利用幾個數值範例來說明求解程序且對主要參數進行敏感性分析。藉由演算法，我們求得不同參數值變動下的最適解，並根據數值分析結果，找出相關的管理意涵與研究結論，期望能提供給決策者擬定訂購策略時的參考。

This study mainly establishes an inventory model for deteriorating items with changing demand under an advance payment-cash-credit trade condition. In the proposed model, the demand is assumed to be dependent on inventory and selling price. In addition, the retailer also offers a trade credit delayed payment by its customers. The main purpose of this study is to determine the optimal price, length of the replenishment period and order quantity so that the retailer's annual total profit is maximum. Further, an algorithm is developed to find the values of optimal solutions and several practical examples are provided to explain the solution procedure and perform sensitivity analysis on the main parameter. Through the algorithm, we obtain the optimal solutions under various values of parameters. And then based on the results of numerical analysis, several relevant management implications and research conclusions are found out. It is hope to provide a reference for decision makers when developing the replenishment and pricing strategies.
