考虑绿色投入水平与回收努力程度的再制造闭环供应链决策研究

The Decision-Making of Remanufacturing Closed-Loop Supply Chain Considering Green Process Input and Recycling Effort

针对单一生产商和单一销售商组成的2级再制造闭环供应链,考虑生产商的绿色投入水平和回收商的回收努力程度,分别在生产商回收和销售商回收2种模式下,构建生产商主导的Stackelberg动态博弈,分析在不同回收商角色下生产商和销售商的定价、绿色工艺投入和回收努力投入的最优决策方案及各自利润的变化.研究结果表明:1)生产商对绿色工艺的投入不受回收商角色的影响;2)当生产商回收时,回收努力程度与生产全新产品与回收再制造产品的成本差呈正相关关系;当销售商回收时,回收努力程度与回收单位产品获利呈正相关关系;3)在销售商回收时生产商获利更多,这说明生产商会优先选择将回收工作委托给销售商.研究验证了改进绿色生产工艺和提高回收率是实现废旧产品循环利用的重要手段,这可以为生产商和销售商的价格制定、绿色工艺投入和回收努力投入的决策提供参考.

For a remanufacturing closed-loop supply chain composed of the manufacturer and the distributor,considering the green process input and recycling effort,the two-stage Stackelberg game models dominated by the manufacturer are established under the two modes of the manufacturer recycling and the distributor recycling,thus analyzing the optimal decision-making of pricing,green process inputs,recycling efforts,and the profits.The results show that no matter who takes on recycling,the manufacturer should make great effort to improve its greenness of products.When the manufacturer recycles,the level of recycling effort is positively related to the cost difference between the production of new products and the remanufactured products.When the distributor recycles,the level of recycling effort is positively related to the compensation of unit recycling product.The manufacturer can gain more profit when the seller recycles,indicating that the manufacturer may prefer to entrust the recycling work to the seller.The research proves that improving the green production process and the recycling rate are important means to realize the recycling of waste products,and can provide reference for the decision-making of producers and distributors for price decision,green process investment and recycling efforts.
