摘　　要：考虑价格影响需求和部分短缺量拖后引起的价格折扣对库存控制补充策略的影响,建立了一种价格影响需求的随机间隔期库存模型,对模型的最优解进行了分析,并针对正态分布的情况进行了测算和说明。分析结果表明,需求特性参数、补货间隔期分布区间等对库存控制影响较大,订货商(尤其是弱势订货商)在制定库存管理决策时必须重点考虑这些因素。With price discounts caused by price demand and partial backlogging impact on inventory policies, an inventory model with random replenishment intervals is presented and the optimization of the model is analyzed. Based on analysis results of normal distribution, it is indicated that the inventory control strategy is considerably affected by the factors such as parameters of demand factor, the range of the replenishment interval and so on. These factors should be paid more attention to by the buyers （especially weak buyers） while making management decisions.
