摘　　要：基于两层次和等级信用支付策略构建了变质性产品的库存模型,即模型假设上游供应商给予下游零售商一个固定的信用支付期,同时零售商对客户实施带有等级区别的信用支付策略.零售商给予信用好的客户全额贸易信贷且不需要任何押金,相反对信用不好的客户不给予贸易信贷的优惠.讨论了模型最优解的存在性与唯一性,并提供了寻求系统最优订货策略的简单方法.最后,给出了具体数值算例和主要参数的灵敏度分析.This paper establishes an inventory model for deteriorating items with two -level and grade trade credit policy .In the model , the supplier in this supply chain offers a fixed credit period to the retailer , and the retailer provides a full trade credit to its good credit customers without the collateral deposits .By contrast , the retailer does not offer trade credit to its bad credit customers .The uniqueness and existence of the optimal solution to the model are testified theoretically , and a simple method for finding the optimal order policy is provided .Finally, numerical examples and sensitive analysis are presented to illustrate the developed model .
