考虑产品绿色度的闭环供应链回收渠道选择研究

Research on the Closed-Loop Supply Chain Recycling Channel Selection with Product Green Degree Taken into Consideration

在考虑产品绿色度的情形下,研究了闭环供应链的回收渠道选择问题。以单一生产商为研究对象,通过构建零售商回收和第三方回收商回收两种Stackelberg博弈模型,得到两种模式下的最优产品价格、回收努力及成员利润,并通过单调性分析和算例分析进行验证。结果表明:两种回收模式下,产品绿色度与最优零售价格和供应链总利润均成正比,而与最优回收努力成反比;第三方回收商的回收努力高于零售商,而两种模式下零售价格的高低存在临界值;当第三方回收成本节约率较低时,生产商应选择零售商回收模式,而当第三方回收成本节约率较高时,生产商选择第三方回收商回收模式。

With the green degree of products taken into consideration,a research has been carried out on the selection of recycling channels in closed-loop supply chain.Taking a single manufacturer as the research object,based on the construction of two Stackelberg game models of retailer recycling and third-party recycling,results can be obtained of the optimal product price,recycling effort and member profits under the two models,to be verified by a monotonicity analysis and case analysis.The results show that under the two recycling modes,the green degree of products is in direct proportion to the optimal retail price and the total profit of the supply chain,but in inverse proportion to the optimal recycling effort;the recycling efforts of third-party recyclers are higher than those of retailers,with a critical value for the retail price under the two modes.When the third-party recycling cost saving rate is low,it is suggested that the manufacturer choose the retailer recycling mode.When the third-party recycling cost saving rate is high,it is advisable for the manufacturer to choose the third-party recycling mode.
