非对称需求信息下两阶段供应链协调

针对由一个供应商和一个零售商组成的供应链，其成员之间的市场需求信息不对称问题，建立了非对称信息下批发价与订货量的stackelberg博弈模型，给出了零售商和供应商分别拥有需求信息下的博弈均衡．效值实例分析了非对称信息对价格和订货量及利润的影响，同时给出了信息不对称下的供应链协调机制。

Coordinating a two-stage supply chain under asymmetric demand information

To the problem of one-supplier one-retailer supply chain with asymmetric demand information between the two members, a Stackelberg game model about the wholesale price and lot size decision under asymmetric information is constructed. The price and quantity game equilibriums are given in the case of the supplier or the retailer owning the demand information respectively. Numerical analysis is used to identify the effect about profits and lot size under asymmetric information. The supply chain coordination mechanisms are proposed.
