二级供应链不同博弈研究

Different game models for a two-stage supply chain

研究了由一个制造商和一个分销商构成的二级供应链上厂商在两种讨价还价模型,即:委托-代理博弈模型和合作博弈模型下的收益.通过比较得出结论:合作是对非合作的Pareto改进,同时消费者也会从中获益.在合作博弈模型中,比较了各种解法,并对K-S解法进行了改进,提出了按参与人的贡献量分配收益的方法,得到的博弈均衡解更加合理.对供应链上厂商之间的合作有较强的指导意义.

The payoffs of manufacturer and retailer under two different bargaining game models, principal-agent game and cooperative game, are studied. The conclusion is suggested that both the players will obtain morn profit by cooperating, and the consumers can also get benefit at the same time. In the cooperative game model, the K-S solution is improved and a new method of allocating total profit based on the player＇ s distributions is introduced. The equilibrium of this game becomes more reasonable, having good directive meaning for the corporation of manufacturers lying on the supply chain.
