考虑风险偏好的双供应链质量改进策略

Quality improvement strategy in two supply chains considering risk preference with uncertain demand is investigated. The factor of enterprises' risk preference and value loss function are introduced. By analyzing quality activities in integrated and decentralized supply chain, seven strategic combinations are divided in two supply chains: NN、OII、ODD、OID、TII、TDD、TID. Meanwhile, manufacturers' and suppliers' functions of utility-quality are established respectively. Based on utility maximization, the optimal strategies of quality improvement under different scenarios are obtained. Finally, numerical examples are used to test rationality and scientific of the models and manifest that quality preference has an important impact on the optimal strategy of quality improvement in two supply chains.
