考虑替代效应的服务终端两周期闭环供应链决策分析

A Decision Analysis of Service Terminal Two-Period Closed-loop Supply Chain Considering Substitution Effect

为分析替代效应对服务终端闭环供应链决策的影响,在不同责任主体负责回收和再制造的情形下,构建服务终端两周期闭环供应链决策模型。采用Stackelberg博弈法,求解回收商负责回收和再制造商负责再制造、回收商负责回收和制造商负责再制造、制造商负责回收和再制造3种模式下的均衡解,并分析其随替代效应的变化趋势。研究表明,制造商负责回收和再制造模式下的第1周期内新品销售价格最低、新品需求量最多、回收率最高;当制造商从事再制造时,相对于回收商负责回收,由制造商负责回收有利于提高第2周期回收率,并降低再制造品销售价格、扩大其市场需求;在第2周期,替代效应的增强总会促使新品的价格降低和再制造品需求量的增加,对回收率也有提升效果。

To analyze the influence of substitution effect on the decision-making of service terminal closed-loop supply chain,based on the different responsibility subjects of recycling and remanufacturing,a two-period decision-making model of service terminal closed-loop supply chain was established.Then based on Stackelberg game method,the equilibrium solutions were solved under three modes:the recycler is responsible for recycling and the remanufacturer for remanufacturing;the recycler is responsible for recycling and the manufacturer for remanufacturing;and the manufacturer is responsible for both recycling and remanufacturing,and the variation trends of equilibrium solutions with substitution effect were analyzed.Several results were concluded:(1)when the manufacturer is responsible for recycling and remanufacturing,the sales price of new products is the lowest,the demand of new products is the largest,and the recycling rate is the highest in the first period;(2)when the manufacturer is engaged in remanufacturing,compared with the recycler,it is beneficial to improve the recovery rate,reduce the sales price of remanufactured products and expand the market demand when the manufacturer is responsible for recycling in the second period;(3)The enhancement of substitution effect will reduce the sales price of new products,and increase the demand of remanufactured products,and also improve the recycling rate in the second period.
