供应链计划建模中的博弈方法

Collaboration Planning Modeling Based on Game Theory for Supply Chain

基于供应链管理思想,针对供应链上下游的主要合作伙伴关系,建立一种基于协商的上下游合作计划模型·根据外界情况(如价格、库存等因素),确定企业与战略伙伴的合作关系·在合作计划模型的基础上,分别讨论了动态博弈的纳什均衡理论和协商对策理论在模型中的应用·指出供应链的上下游合作企业达到"双赢"目标的条件及可行性·结果表明,非合作博弈体现了一种个人理性,而协商对策满足个人和群体合理性·仿真验证了模型和算法的有效性·

A negotiation-based collaboration planning model (CPM) for supply chain management (SCM) is established with the information shared among the firms upstream and downstream, of which the collaboration among a firm and its strategic partners involves such external factors as price and inventory. The applications of both Nash equilibrium of dynamic game and bargaining game theory to CPM is discussed. The possibility and feasibility of attaining the goal of win-win and the conditions required are discussed for the cooperative firms upstream and downstream in SCM. Results show that non-cooperative game only focuses on the individual sense, while bargainning game concerns the sense of the groups as well as the individuals. The simulation verified the model and algorithm's effectiveness.
