摘要

本研究將顧客到達之間隔時間與每位顧客所購買之商品數量皆視為隨機變數，並考量在此情況下，如何進行存貨策略之擬訂以達利潤極大化之目標。然而，在不同時段下，由於需求量並不相同，故人力需求也有所變動。因此，考量在不同參數下，如何找出最適訂購量與人力規劃即為本研究之探討重點。本文由交易資料切入，經由統計方法之推導，與易腐性商品之訂購策略進行結合，再針對修訂之報童模式之相關內容進行推導，並對相關參數進行敏感度分析，且根據交易資料找出最適人力規劃。最後，列舉範例進行分析與驗證，並提出五點具體結論供後續研究及實務應用之參考。

In this research, the interarrival time of each customer into a store and the purchasing quantities of perishable goods by customers can be seen as random variable. Under this circumstance, it is a very important issue for decision makers to plan an optimal inventory strategy to maximize the total expected profit. However, the demand of product and manpower allocation are variate in different periods. Therefore, the main purpose of this study is to formulate an inventory mathematical model under the consideration for different parameters. Based on transaction data and optimization techniques to find out the optimal ordering quantity to maximize the total expected profit. Sensitivity analysis is also taken for system parameters. Sum up all of products’ transaction data in each period to decide the suitable manpower allocation. Finally, a numerical example is analyzed, and demonstrated. Five conclusions were drawn for further studies and practical applications.
