摘　　要：文中建立了一类需求率跟销售价格及时间相关的短生命周期易变质物品库存模型,考虑了供应商提供价格折扣和零售商提供临时价格折扣。目的是优化补货周期使得总利润最大,证明了模型最优解的存在性,给出了求解最优解的算法,并给出数值例子。In the paper, under the assumption of supplier offering price discount and retailers offering temporary price discount in the life cycle, an inventory model for deteriorating items with the short life cycle is established and the demand is a function with respect to sales price and time. Our aim is to optimal replenishment cycle so that the total profits is maximum, then the existence of the optimal solution for the model is discussed and an algorithm is given to solve the optimal solution. Finally the numerical example is presented.
