供应链环境下基于服务水平约束的联合库存模型

The Integrated Vendor-Buyer Inventory Model with Service Level Constraint under Environment of Supply Chain

联合库存(JMI)是供应链库存管理研究的一个热点,近年来引起了不少学者的注意。联合生产库存模型是研究联合库存策略的主要模型之一。考虑一个典型的单一产品的二级供应链系统:单供货商(卖方)-单销售商(买方),假定企业不允许缺货以及外部对买方的需求量是一个服从正态分布的随机变量,建立了基于服务水平约束的联合生产库存模型;利用文献[6]中的数值例子验证了模型的有效性,文章同时也为联合库存策略的实施提供了一种简单易于控制的思路和方法。

Jointly managed inventory （JMI） is a researchful hotspot in the supply chain manatement（SCM）,that intereste a lot of scholar. Integrated vendor-buyer inventory model is one of the ways for study joint inventory strategy.This paper consider a singlevendor single-buyer integrated system,assume that buyer don＇t want to make their inventory out of stock,and the buyer＇s external demand is a normal stochastic variable.With the constraint of service level,we develop an integrated vendor-buyer inventory model. Using the data that given by Ouyang etc ,we give a example to examine the validity of the model.The article also provide a simple ways and means that easy to control for implement the strategy of JMI.
