信息共享环境下多级复杂供需链系统的库存成本分析

Inventory cost analysis of complex multi-echelon supply chain with information sharing

以一个制造商、多个互异的分销商和多个互异的零售商组成的复杂供需链系统为研究对象,建立了供需链系统库存成本模型,对各个企业的信息共享价值进行了分析计算。结果表明,制造商和分销商均能够从共享零售商的需求信息中获利,而零售商则从信息共享中得不到任何利益,因此需要制订一定的利益分配机制,以促进供需链信息共享的实现。

A complex three-echelon supply chain system involving one manufacturer, many different distributed centers and many different retailers was studied and its inventory cost model was constructed to compute the value of information sharing. The result showed that retailers could not benefit from information sharing with upstream members, but distributed centers and manufacturers could reduce their inventory cost by sharing demand information with retailers. Therefore, an effective benefit allocation mechanism within the supply chain should be formulated to ensure retailers benefit from information sharing.
