基于CVaR和公平偏好下双渠道供应链回购契约

Study on Improved Buyback Contract Based Coordination of Bi-channel Supply Chains Based on CVaR and Fairness Preference

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.

Risk-based measurement criteria CVaR, retailers have a decision model was con- structed based on dual-channel efforts buyback contract equitable cost sharing of psychologi- cal and behavioral preferences, the analysis of the decentralized and centralized dual-channel supply chain system of decision-making behavior. On this basis, after solving theoretical and numerical example, in-depth analysis of the fairness preference, risk aversion member inter- action features and repurchase contracts. The study found that the more averse retailers and manufacturers, to avoid the risk, the lower the order quantity, their profits and supply chain profits will decline; Accompanied by a~ fair number of orders retailer and wholesale prices increased preference coefficient decreasesBut even taking into account the risk aver- sion channel members and fairness preference feature, simply by improving the parameters of the value of the repurchase contract properly, it is possible to make dual-channel supply chain to achieve coordination.
