摘　　要：针对供应商管理库存(VMI)系统中订货商规定库存水平上限问题,考虑供应商采用让订货商处产品的库存量不超出其库存水平上限和承担一定的惩罚成本情况下超出其库存水平上限两种供货策略,分别建立了供应商采购原材料并生产产品且订货商处缺货需补的VMI模型;运用K-T条件对模型进行了求解,并给出了获得VMI系统最小单位时间总成本的求解步骤;结合算例,分析了相关参数对供应商生产决策以及VMI系统各成本的影响。Aimed at the problem that the retailer sets an upper bound of inventory level in vendor-managed inven- tory, two VMI models are given by considering that vendor employs two supply decisions： They make retailer in- ventory level not beyond this upper bound or opposite while paying a penalty cost. In these two models the vendor procures raw material and then production and backorder is allowed at the retailer location. We solve the two models by K-T condition and solving steps are also given. A numerical example is included to examine the im- pact of related parameters on vendor＇ s production decision and each cost of VMI system.
