构建了3种基于以旧换新策略的闭环供应链决策模型,包括集中决策模型(C)、制造商销售第三方回收商回收模型(M3P)、零售商销售第三方回收商回收模型(R3P),并分别讨论了模型的最优定价与回收策略.通过理论与数值分析表明:制造商和整个供应链系统所获得的利润方面,模型C优于模型M3P,而模型M3P优于模型R3P;而第三方回收商所获得的利润方面,模型M3P也优于模型R3P;此外,根据产品全生命周期评估方法进行环境绩效分析,结果表明在环境绩效的表现上不存在具有绝对优势的模型.This paper develops three decision models for closed-loop supply chains( CLSC) with trade-ins,including the centralized decision model( model C),the manufacturer selling and the third-party collecting model( model M3P),and the retailer selling and the third-party collecting model( model R3P),and investigates the optimal pricing and collection strategies for each model. The theoretical analysis and numerical experiments show that,in terms of the profits obtained by the manufacturer and the whole supply chain,model C dominates model M3 P and model M3 P dominates model R3P; in terms of the third-party collector's profits,model M3 P dominates model R3 P. However,in terms of environmental performance,none of them dominates the others according to the life-cycle assessment methodology.国家自然科学基金资助项目(71371158;71671151
