摘　　要：基于时变需求的库存问题一直是库存管理者关注的重点之一,大多数基于二层信用支付的库存模型都是假设需求率为常数.假设需求率是时间的指数函数,建立了二层信用支付条件下的变质物品库存模型,并证明了最优解是存在且唯一的,给出了确定最优补货策略的算法步骤,最后通过数值例子对主要参数进行了灵敏度分析.one of the point of the inventory problem based on time-varying demand has been focused by inventory managers.Constant demand rate is considered in most of inventory model under two levels of trade credit policy.The paper develops an inventory model under two levels of trade credit policy,in which suppose demand rate is exponential function of time.The article proves existence and unique of optimal solution for the inventory model and presents the algorithm of determining optimal replenishment policy.Finally the sensitivity analyses of the main parameters are presented by numerical examples.
