考虑公平关切的服务供应链协调契约

Coordination contract of service supply chain considering fairness concerns

针对服务集成商公平关切行为,建立了服务提供商和服务集成商的博弈模型,分析论证了批发价契约无法实现服务供应链协调的问题,探讨了"成本共担+收入共享"组合式契约协调的有效性.研究结果表明,成本共担契约和收入共享契约都无法实现服务供应链的协调,而组合式契约不仅能有效协调服务供应链,且协调具有一定柔性,但随着服务集成商公平关切程度的增加,服务提供商与服务集成商的协调空间变小,协调柔性减弱,且对服务提供商更不利.

Considering fairness concerns of the service integrator, a game model of the service provider and the service integrator is established. The analysis demonstrates that the wholesale price contract can’t realize the service supply chain coordination. Therefore, a combined contract of“cost sharing and revenue sharing”is presented to coordinate the service supply chain, and its effectiveness is discussed. The study results show that：the contract of cost sharing and revenue sharing can’t achieve the coordination of service supply chain, the combined contract can’t only coordinate the service supply chain, and also its coordination has flexibility. But with fairness concerns of the service integrator increasing, the negotiation space of the service provider and the service integrator becomes small, and the coordination flexibility will gradually weaken and more unfavorable for the service provider.
