摘　　要：考虑到易变质商品在一个销售周期内会有一定数量的商品发生变质,构建了一个考虑在一个销售周期内所产生的变质数量可折价回购以及库存水平影响需求的易变质品的库存模型,而且针对销售周期内的缺货数量,模型假定采取部分延迟订购的策略。针对这一模型,给出了平均利润函数并证明了其存在最优解,然后通过算例完成了不同销售价格、不同折价回购比例和不同库存影响因子条件下的最优订货策略的确定以及其余相关参数的灵敏度分析,分析结果可对零售商的订货策略有一定的参考价值.Considering perishable goods will have a certain amount of deteriorate products in a sales period, this paper constructed a perishable goods inventory model based on deteriorate quantity can be buyback at a discount and Inventory-level-dependent demand rate in a sales period, and the unmet demand is partial backlogged in the shortage period. Then we prove that the average profit function exits an optimal solution. Last, we find an optimal ordering policy based on different sales price, different proportions Price Break buyback and different stock affect factor through a numerical example, and we also conduct the sensitivity analysis on the parameters. Analysis results for retailers ordering policy has a certain reference value.
