考虑社会责任和质量努力的服务供应链最优策略

研究考虑服务集成商具有企业社会责任行为,服务提供商进行服务质量努力的服务供应链最优策略问题.在量化企业社会责任和服务质量努力的基础上,建立了具有行为特征的提供商和集成商的效用函数,并以服务供应链成员效用最大化为目标,对模型进行优化分析,得到不同约束条件下最优的企业社会责任、服务质量努力以及价格等最优决策策略.通过数值仿真发现:首先,多数情形下服务供应链成员的最优效用分别与集成商对社会责任投资预算的上限和提供商对服务质量努力投资预算的上限成正比.其次,为保证效用最大化,集成商在提高企业社会责任的同时,应尽可能选择质量努力较高的提供商进行协作.第三,提供商为获得最优效用,应尽量选择企业社会责任较好的集成商进行协作.但提供商不可盲目通过提高质量努力投资预算来增加企业效用.

Optimal Strategy in Service Supply Chain Considering Social Responsibility and Quality Effort

Considering the corporate social responsibility of service integrators and service quality effort of service providers， optimal strategy in service supply chain is investigated. Utility functions of service integrators and service providers with behavior characters are established based on the quantization of corporate social responsibility and service quality effort. Models are optimized to maximize members’ utilities; thereby， optimal strategy of corporate social responsibility， service quality effort and price are obtained under different constraints. The numerical simulation shows service supply chain members’ optimal utilities have positive correlation with the upper limit of integrators’ social responsibility and providers’ investment budget of service quality effort in most situations. Secondly， in order to ensure the maximum utility， integrators should improve corporate social responsibility and select providers with higher quality effort to collaborate. Finally， to obtain the optimal utility， providers should choose integrators with better corporate social responsibility to collaborate. However， providers should not increase enterprises’ utility blindly by enhancing the investment budget of quality effort.
