新产品质量对闭环供应链再制造模式选择的影响

研究了新产品质量对闭环供应链回收再制造模式选择的影响。借助博弈论，建立了原制造商外包再制造和授权再制造的Stackelberg博弈模型，利用逆向归纳法解得两个模型的均衡解和供应链利润，并对均衡结果进行了比较分析。研究发现：外包再制造模式的供应链利润、消费者剩余、社会福利均优于授权再制造模式。原制造商选择外包再制造模式的利润要高于授权再制造模式，而第三方制造商最优策略受再制品价值折扣与新产品质量的影响。当再制品价值折扣系数与回收规模满足一定条件，而且新产品质量较高时，原制造商采取外包模式对环境更加友好。

Effect of New Product Quality on Remanufacturing Models in Closed-loop Supply Chain

Considering the quality of new products, the choice of OEM (original equipment manufacturers) and 3PR(third-party remanufacturers) on closed-loop supply chain remanufacturing model is studied. We develop two Stackleberg models where manufacturers perform remanufacturing operations through either outsourcing or authorization based on game theory. The backward induction analysis method is applied to get the equilibrium solution and supply chain profits on remanufacturing operation selections. This study compares these two models by modeling the game results between the OEM and the 3PR.The results suggest that the outsourcing approach under Stackleberg Game get an advantage over authorization approach in supply chain profits, consumer surplus and social welfare. In both scenarios, the OEM obtains higher profits through outsourcing approach. The 3PR has different selection in terms of the consumer value discount for the remanufactured product and new product quality. When the consumer value discount for the remanufactured product and the scaling parameter meet certain conditions, as well as the high quality of new products. Outsourcing remanufacturing is more environmentally friendly than authorization remanufacturing.
