双渠道销售差别定价闭环供应链协调应对生产成本扰动研究

摘要

This paper develops a two-part tariff contract model in one-manufacture-two-competitive-retailers closed-loop supply chain( CLSC) which sells new and remanufactured products by different retailers and in differ-ent prices.Then, we consider optimal decisions of centralized dual-channel differential price CLSC under the sit-uation that the cost of new and remanufactured products is disturbed simultaneously, and improve the two-part tariff contract to coordinate the CLSC under cost disruption.The results indicate that compared with the central-ized decision under normal environment, the optimal adjustment plans of new and remanufactured products are not only related to the extent of the cost disruption, but also related to the substitute coefficient of the two prod-ucts.Moreover, the improved two-part tariff contract can finally coordinate the CLSC under cost disruption by sharing risks among members.%针对一个新产品和再造品存在差别定价，且两类产品通过不同销售渠道进行销售的闭环供应链，构建了一个基本的两部收费契约协调模型。随后，考虑突发事件同时干扰新产品和再造品生产成本的情况下，集中式决策闭环供应链的最优决策问题，并设计了可协调成本扰动下双渠道销售差别定价闭环供应链的两部收费契约。研究表明：在集中式决策闭环供应链中，相比于稳定环境下新产品和再造品的最优决策，生产成本扰动下两类产品最优产量的调整方式不仅与生产成本扰动的程度相关，还与两类产品之间的相互替代系数相关，且改进的两部收费契约以系统各成员共担风险的方式实现了闭环供应链协调的目的。
