碳排放限制下S-M两级回收闭环供应链价格决策

摘要

Considering carbon emission limits for suppliers and manufacturers,this paper investigates a supplier-manufacturer closed-loop supply chain with two-echelon recovery in which the supplier participates in the compo-nents recycling.This study compares and analyzes the retail price,wholesale price,and the profits of the supply members under the two conditions of with and without carbon emission limits.Theoretical analysis shows that, the difference of retail price between with and without carbon emission limits depends on the rate of recovery;the difference of wholesale price between the two cases of with and without carbon emission limits is related not only to the rate of recovery,but also to carbon emissions restrictions, market demand of products, the proportion of ineffective parts in the recycled products and carbon emission reduction coefficient.Finally,a numerical example is considered to verify the conclusion of this paper.%考虑对供应商和制造商有碳排放限制,研究供应商参与零部件回收再制造的供应商和制造商两级回收闭环供应链.比较分析了对供应商和制造商有无碳排放限制两种情况下产品的零售价格、批发价格以及制造商和供应商的利润.分析表明:制造商在有无碳排放限制两种情形下的零售价格之差与回收率有关;供应商在有无碳排放限制两种情形下的批发价格之差不仅与回收率有关,还和政府的碳排放限制政策、产品市场需求状况、回收产品无效零部件比例以及通过回收再制造产品的碳减排系数有关.最后,通过数值算例验证文中的结论.
