基于博弈论的多零售商参与下逆向供应链定价策略及利润分配

Pricing strategies and cooperative profit distribution based on game theory for reverse supply chains with multi-retailer participants

为解决多个零售商参与下的逆向供应链中的定价策略和利润分配问题,运用Stackelberg博弈理论,求出了逆向供应链中各成员在非合作和合作两个博弈结构下的最优定价策略,并从理论上证明了联合定价策略下回收价格提高、回收量增加,整个逆向供应链系统的利润也增加,由此说明各方合作有利于商家和消费者;利用改进的K-S解法,给出了合作成员之间根据各自对合作联盟的贡献来分配增加利润的方案。通过数值算例验证了所得结论的正确性。

To solve the problems of pricing strategy and profit distribution in reverse supply chain involving multi-retailer participants,the optimal pricing strategy for the members in supply chain was obtained under both cooperative and non-cooperative game ways based on Stackelberg game theory.And it was theoretically proved that the recycling prices were appreciated and the quantities of recycled products as well as the profit of the whole reverse supply chain system were increased under joint pricing strategy.Thus the cooperation of all sides was beneficial to both sellers and consumers.By using improved K-S solution,the allocation scheme on how to distribute profit among the members was designed according to their contribution to the cooperative alliance.The validity of conclusions was verified by a numerical example.
