摘　　要：文章对时滞变质物品的库存模型进行了研究。假设允许缺货且短缺量拖后率为指数函数,通过建立库存模型分析变质品在缺货时点发生在变质期前和变质期后的总成本,最后,给出了数值算例对模型进行阐释。研究结果表明:缺货时点发生在变质期前的库存成本比发生在变质期后小。In this paper,we research the inventory model of delay items.Propose stock-out is allowable and the back logging rate is index function.By establishing inventory model to analysis the total cost of metamorphic product,when the point out of stock is happened before and after the period of metamorphic.Finally,a numerical example is given to explain the model.The results of the study show that： The inventory cost of point out of stock happened in the period before metamorphic is smaller than happened in metamorphic period.
