不对称信息下供应链库存成本控制模型

考虑到信息不对称对供应链企业库存成本控制造成的影响,以单个制造商和单个零售商组成的一个两级供应链为研究对象,假设供应链企业的产品需求与时间有关,分别分析了信息对称和信息不对称条件下,制造商、零售商和供应链整体的利润情况,并建立了相应的数量折扣协调机制,研究其对三者成本控制的影响.研究表明,在信息不对称的条件下,该协调机制可以有效降低制造商、零售商以及供应链整体的库存成本,达到了良好的供应链协调效果.最后通过算例分析进行了验证.

Inventory Cost Control Model in a Supply Chain Under Asymmetric Information

Being taken the impact of the information asymmetry on cost control in supply chain,a supply chain composed by a manufacturer and a retail was established.Supposing that the demand was time-related,in the two situations of information symmetry and information asymmetry,the whole profit situation of the manufacturer,the retail merchant and the supply chain was analyzed and the quantity discount coordinated mechanism was established accordingly.Research results showed that this reasonable coordination mechanism could effectively reduce the supply chain inventory cost.In the end,an example was made which illustrates the correlative conclusions.
