闭环供应链回收渠道与成本分摊机制研究

Reverse Channel and Cost Sharing Mechanism in Closed-loop Supply Chain

本文基于废旧产品的回收再制造,研究了零售商和制造商组成的闭环供应链。作者分别建立零售商回收和制造商回收两种模型,运用逆向归纳法求解分析不同模型对各成员利润的影响,指出成本分摊机制可以使闭环供应链达到协调。最后,选取合理的数据对结论进行验证,并就需求对价格的敏感系数及分摊比例等参数对回收率和利润值的影响做了分析。结果表明:一定条件下,制造商负责回收废旧产品要优于零售商负责回收;成本分摊契约可以提高回收率和各主体的利润值。

Based on the recovery and remanufacture of end-of-life products, this paper studies the closedloop supply chain which is composed of retailers and manufacturers. Researchers build manufacturers recovery model and retailers recovery model separately. With backward induction, this paper analyzes the impact on every member that different models lead to. And it points out that there could be a coordination in closed-loop supply chain under cost sharing. At the end, this paper selects reasonable data to verify the conclusions and analyzes the effect of parameters like cost sharing ratio and sensitivity coefficient between demand and price on recovery rate and profit rate. It turns out that under some specific conditions, comparing with retailers in charge, it＇s better that manufacturers take charge of retrieving. It also turns out that cost sharing contract can improve both recovery rate and every main body＇s profit rate.
