本研究主要探討在允許預付－現金－信用交易條件的交易條件下，建立一個考慮變動需求且具有效期限之退化性物品的存貨模式。在此模式中，我們假設需求率與新鮮度跟貨架陳列水準有關，以及退化性物品具有效期限。本研究主要的目的是決定最適的時間長度、補貨期間長度及訂購量使得零售商的全年總利潤為最大。藉由數學分析，我們找出上述信用交易條件下的最適決策與最適全年總利潤。進一步，我們利用幾個較符合實際的數值範例來說明求解程序並對主要參數進行敏感性分析。最後根據數值分析結果，找出相關的管理意涵與研究結論，並期望能提供給決策者擬定訂購策略時的參考。

This study mainly discusses the conditions for allowing advance-cash-credit payments trade conditions, establish an inventory model for deteriorating items with effective deadlines. The demand rate is assumed to be related to freshness and the shelf display level. The main purpose is to determine the optimal length of time, the length of the replenishment period and the order volume so that the retailer's total profit for the year is the maximum. Through mathematical analysis, we find out the optimal decisions and the optimal total annual profit under the above credit transaction conditions. Further, we use several realistic examples to illustrate the solution and perform a sensitivity analysis on the main parameters. Finally, according to the results of numerical analysis, to find out the relevant management implications and research conclusions, and hope to provide a reference for decision makers when formulating ordering strategies.
