基于风险度量准则CVaR,构建了零售商具有公平偏好心理行为下基于努力成本分担的回购契约的双渠道决策模型,分析了分散式和集中式双渠道供应链系统中的决策行为.在此基础上,经过理论求解与算例分析,深入分析了公平偏好、成员的风险规避特性和回购契约的交互影响.研究发现:零售商与制造商越厌恶、规避风险,订货数量就越低,他们的利润和供应链的利润都将降低;零售商的订货数量伴随公平偏好系数和批发价的增大而减少.但即使考虑渠道成员的风险规避性和公平偏好特性,只须回购契约的参数取得当的值,就可以协调双渠道供应链.
Based on CVaR, a dual-channel decision-making model for retailers with buy-back contracts based on effort-sharing under fair-minded psychological behavior is constructed, and the decision-making behaviors in decentralized and centralized dual-channel supply chain systems are analyzed. On the basis of theoretical analysis and case study, this paper analyzes in depth the interaction between fairness preferences, risk avoidance characteristics of members and repurchase contracts.The study found that: the more disgusting retailers and manufacturers risk aversion, the lower the order quantity, they The profit of the supply chain and the profit of the supply chain will decrease. The retailer’s ordering quantity decreases with the increase of the fair preference coefficient and the wholesale price, but even considering the risk aversion and fairness preference of channel members, Get the value, you can coordinate dual-channel supply chain.
