单供应商面对具有多个销售点的零售商时的VMI模型研究

在供应商管理用户库存（VMI）环境中,当面临的具体条件不同时,供应商和零售商的利润分配是不同的,论述了当一个供应商面对具有多个销售点的零售商时的VMI模型,此时供应商负责库存决策,他可以在各个销售点之间转运（Transshipment）库存.建立了供应商和零售商的一个Stackelberg博弈,零售商作为领导者是通过决定销售价格来体现的.结果显示最终供应商和零售商可以达到一个子博弈精练纳什均衡,零售商在该模式下获得了很大的利润份额.给出了一个算例计算了均衡时的库存量和销售价格.

Study of VMI Model When a Supplier Faces a Retailer Who Possesses of Several Retail Points

In the case of vendor managed inventory(VMI),the profit allocation between a supplier and a retailer is different when conditions are different.A special VMI model is discussed when a supplier faces a retailer who possesses of several retail points,and the supplier can transship inventory between different retail points.The interaction between the supplier and the retailer is modeled as a Stackelberg game with complete information,where the retailer acts as a leader by setting the retail price.It is shown that Stackelberg-Nash equilibria exist in our dynamic game model.And the retailer obtains a great share of benefit from this mode.Our findings are illustrated by a numerical example at last.
