建立了在分散式决策和集中式决策2种情形下两周期再制造闭环供应链的决策模型,得出了制造商的最优批发价格和回购价格、零售商对新产品和再制造产品的差异定价以及双方的利润,并分析了不同参数变化对价格、回收率和利润的影响。将2种情形下的最优决策结果进行了比较,结果表明分散式决策下存在双重边际效应,系统效益非最优;利用收益共享契约来协调闭环供应链,通过算例验证了所得结论的正确性。
This paper establishes decision-making models in two-period remanufacturing closed-loop supply chain in two cases: decentralized decision and centralized decision.Manufacturer's optimal wholesale price and buyback price,retailer's price differentiation between new and remanufactured products and their profits in two cases are derived.Changes of different parameters' impacts on pricing,collection rate and profits are analyzed.Then optimal decision-making results of decentralized decision and centralized decision are compared.The results show that 'double marginalization effect' exists in decentralized decision and its system profit is not optimal.Revenue sharing contract is utilized to coordinate the closed-loop supply chain.Finally the conclusions are verified by examples.
