  2. This paper develops a deterministic inventory model for perishable items with a mixture of back orders and lost sales under inflation and time discounting, where the backlogged demand rate is dependent on the negative inventory level during the stock out period. the main differences from the existing related models are that the present model takes the maximum present value of profit in a repeatable order cycle as the objective function and proposes a more practical constraint of maximum customer - waiting time to ensure a proper customer service level. then the existence and the uniqueness of the solution to relevant systems are examined and a solution algorithm is shown to find the optimal replenishment policy. at last, some numerical examples are presented to illustrate the applicatioh of the model

    本文建立一種考慮通貨膨脹與時間價值變質性物品模型,在模型中允許短缺發生且拖后需求速率與在缺貨期間已經發生缺貨有關.和已有相關模型主要區別在於本模型把一個可重復訂貨周期內平均利潤凈現值作為目標函數,且增加在缺貨期間最長顧客等待時間限制,以確保系統擁有較高服務平.然後討論模型最優解在性與唯一性,並提供尋求模型整體最優解演算法.最後用實例說明此模型在實際中應用
