基于博弈论的闭环双渠道回收供应链决策研究

Research on Decision-Making of Closed-Loop Supply Chain for Dual-Channel Recovery Based on Game Theory

基于当前包装回收难以及资源损耗大的问题,研究在制造商、销售商和第三方回收商构建的闭环双渠道回收供应链中,基于供应链参与主体博弈权力的差异,构建制造商主导、销售商主导、第三方回收商主导的3类Stackelberg博弈及集中决策博弈模型,给出并比较分析4种模型的最优解。研究表明:与集中决策相比,分散决策收益非帕累托最优,利用改进的收益分享契约对各个分散决策下的供应链进行协调。通过数值仿真分析来验证模型的正确性和协调机制的有效性。

To tackle the difficulties and resource depletion in current packaging recycling,this paper constructs a centralized decision-making game model and three Stackelberg game models.Specifically,these Stackelberg game models are developed depending on the differences in the game power of participants in the closed-loop supply chain for dual-channel recovery,respectively corresponding to the cases where the manufacturer,the distributor or the third-party recycler is dominant.The optimal solutions of the four models are compared and analyzed.The benefits of decentralized decision-making do not reach the Pareto optimality as compared with centralized decision-making.An improved revenue sharing contract is used to coordinate the supply chain under decentralized decision-making.The validity of the model and the effectiveness of the coordination mechanism are verified by numerical simulation.
