摘　　要：易变质物品库存管理策略一直是实务界与学术界高度关注的问题,其中具有有效期易变质物品的最优补货策略是研究中的难点。本文研究了有限销售时域内具有有效期易变质物品的库存补货策略,在物品的需求率依赖于物品的库存水平,且物品有效期已知的假设下,本文建立了一个确定易变质物品最优补货策略的优化模型,并给出了具体的求解算法。文章最后给出了数值算例,并对模型中的相关参数作了敏感性分析。The research of inventory policies for perishable items has been focused by the industries and the researchers. However, it is verydifficult to find the optimal replenishment policy for the items with fixed lifetime. Under the condition of finite horizon, this paper studies the optimal inventory ordering policy for the fixedlifetime items. Assuming the demand rate depend on the inventory level and the lifetime of the perishable items is finite and determined, we formulate a model and give an arithmetic to determine the optimal replenishment policy. We give the numerical results and make sensitive analysis at the end of the paper.
