基于不对称Nash协商模型的供应链协调机制研究

研究了一个由制造商、零售商和第三方物流商组成的供应链优化问题，构建了基于不对称Nash协商机制的供应链协调模型。首先，建立了供应链三方在独立决策下的利润模型，并求出各自的最优解；其次．建立了集中决策下的供应链利润模型，并得到系统最优解；再次，利用不对称Nash协商模型协调三方利益，并求出协调批发价格和协调物流服务价格的表达式；最后．用算例证明，上述Nash协商模型能够增加供应链各方的利润。

A study on coordination mechanism of supply chain based on asymmetric Nash negotiation model

This paper studies the optimization issue of the supply chain, which is composed of a manufacturer,a retailer and a third party logistics provider,and builds the supply chain coordination model based on the asymmetric Nash negotiation mechanism. Firstly,we establish the three members＇ profit models based on the independent decision and solve their optimal solutions. Secondly, we set up the supply chain profit model and find out the system＇s optimal solutions under centralized decision. Thirdly,we coordinate the three parties＇ profits by using the asymmetric Nash negotiation model and get the expressions of the coordinating wholesale price and logistics service price. I.astly,we provide a numerical example which illustrates that the above Nash negotiation model can increase the profits of all parties in the supply chain.
