闭环供应链的研究对企业废弃物回收决策有很强的指导意义。文中主要研究不对称信息条件下零售商回收的契约协调机制与制造商回收的契约协调机制,制造商始终为主从博弈的领导者,零售商为跟随者,根据主从博弈的理论求解出各个参与方的最优反应函数,并分析利用实际算例和图像验证分析得到的结果。 The research of closed-loop supply chain has a great guiding significance for the decision-making of enterprise waste recycling. In this paper, we mainly study the contract coordination mechanism recovered by retailers under the condition of asymmetric information and the contract coordination mechanism recovered by the manufacturer. The manufacturer is always dominated by the game leader and retailer as the follower. According to the theory of master-slave game, The optimal response function of the participants, and analyze the results obtained by the actual examples and image verification analysis.
