摘　　要：在资金具有时值、供应商给零售商提供定期信用支付和价格折扣的支付策略条件下,讨论了需求跟价格相关、变质率为常数的易变质物品库存问题,建立了优化补货周期和销售策略的库存模型,目的是极大化平均总利润。分析了模型最优解的存在性和唯一性,并给出数值实验。In then paper, under the conditions of capital time value and suppliers providing fixed credit payments and trade credit to retailers, the optimal inventory model for deteriorating items is established based on trade credit and cash discounts policy to optimal replenishment cycle and sales policy, which demand rate is dependent on sale price and deterioration rate is a constant. Our aim is maximize the average total profit.
