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
本文建立了一種考慮通貨膨脹與時間價值的變質性物品的庫存模型,在模型中允許短缺發(fā)生且拖后的需求速率與在缺貨期間已經發(fā)生的缺貨量有關.和已有相關模型的主要區(qū)別在于本模型把一個可重復的訂貨周期內的最大平均利潤的凈現(xiàn)值作為目標函數(shù),且增加了在缺貨期間最長顧客等待時間的限制,以確保庫存系統(tǒng)擁有較高的服務水平.然后討論了模型最優(yōu)解的存在性與唯一性,并提供了尋求模型整體最優(yōu)解的算法.最后用實例說明了此模型在實際中的應用
