考虑咨询公司策略的供应链均衡研究

Equilibrium of the Supply Chain with a Consulting Firms Strategy

考虑由1家供应商和多家制造商组成的供应链。另外,存在1家咨询公司对市场需求进行预测,并向制造商出售其预测信息。在考虑咨询公司策略的基础上,对供应链的均衡状态进行了研究。研究发现,供应链的均衡信息结构并不受咨询公司策略的影响,而是由市场本身的性质所决定的。研究还发现,咨询公司的信息服务增加了供应链的期望总剩余以及期望消费者剩余。随着需求不确定性的增加,期望消费者剩余随之增大。

We consider a supply chain consisting of a supplier,a consultant and a few of manufacturers.The consultant forecasts the market demand and sells the forecasting information to the manufacturers.We obtain the equilibrium for all the players analytically.The study shows that the consultant＇s strategies do not influence the equilibrium regarding the number of manufacturers who purchase forecast information.The equilibrium information structure of supply chain is determined by the nature of the endproduct market. We also find that the consultant＇s information service increases total surplus and consumer surplus,and the consumer surplus increases in demand uncertainty.
