考虑链与链竞争下的回收再制造供应链决策研究

Research on Supply Chain Decision of Recycling and Remanufacturing Considering Chain and Chain Competition

本文考虑了两条由两个制造商和两个零售商所组成的竞争性供应链,制造商对一级市场未销售完的产品进行回收再制造后,再通过零售商销往二级市场,且再制造成本与回收努力负相关。在此基础上研究了链与链竞争环境下的最优努力投入、定价决策及制造商是否应投入回收努力的问题,并分析了消费者的价格敏感性变化对制造商和零售商的决策行为和利润的影响。研究发现,竞争性供应链存在唯一的纳什均衡解;若一条链上的消费者对另一条链上的零售价格越敏感,则这条链上制造商的努力水平、零售商的零售价格及二者的利润均会越大;较两制造商不投入回收努力而言,投入合适的回收努力可使得二者的利润获得帕累托改进。

This paper examines two competitive supply chains composed of two manufacturers and two retailers.In particular,the manufacturer recycles the products not sold in the primary market and then sells them to the secondary market through retailers.The manufacturing cost is negatively correlated with the recovery effort.In addition,the optimal effort input and pricing decision-making problem in the chain and chain competitive environment are investigated,and the influence of the change in price sensitivity of the consumer on the decision-making behavior and profit of the manufacturers and retailers is analyzed.Results show that the only Nash equilibrium solution existed in this competitive supply chain;if consumers on one chain are more sensitive to the retail price on the other,the level of effort of manufacturers,price of retailers,and profit of both manufacturers and retailers in this chain become greater.Thus,investing in the correct recovery effort can improve the profits of both retailers compared to those of the two manufacturers that do not invest in recycling efforts.
