考虑质量控制和损失规避的供应链协调研究

研究质量控制和各成员均损失规避背景下的供应链协调问题,应用损失规避效应函数刻画制造商和零售商的损失规避行为,通过分析比较分散决策和集中决策两种模式下的最优策略,引入批发价格-质量成本分担契约构建供应链协调模型,研究表明,该契约能够使质量控制与损失规避背景下的供应链实现协调.通过算例对损失规避程度、产品合格率和销售价格等参数进行灵敏度分析,揭示了损失规避和质量控制等因素与最优产品质量水平、最优订货量以及供应链效用之间的关系.

Coordination of supply chain considering quality control and loss aversion

This paper considers the supply chain coordination problem based on quality control and loss aversion. The behavior of loss-averse manufacturers and loss-averse retailers is portrayed by the loss-averse utility. Then, the optimal strategies of the manufacturer and retailer are analyzed at the decentralized supply chain and centralized supply chain respectively. And a supply chain coordination contract model is constructed by combining the wholesale price contract and the quality cost sharing contract, and the study shows that the supply chain considering quality control and loss aversion can achieve coordination using the contract. Furthermore, under the decentralized and centralized supply chain, a numerical example is given to conduct sensitivity analysis on parameters of the proposed model, and the parameters include loss aversion, qualified rate of products, wholesale price and so on. Through the analysis, the relationship among loss-averse, quality control and optimal product quality, optimal order quality, supply chain utility can be revealed.
