Research On Auto Parts Suppliers Services Game And Optimization Based On Service-embedded Manufacturing

Comparing with developed country, automobile industry is a newly developing and leading industry in china. In the industry chain, domestic automotive parts suppliers mainly compete in market depending on abundant materials, low labor and energy cost, in which the disadvantageous factors exist such as small scale, poor ability of independent innovation,low technical content and thus at the low end in the global automotive value chain and severely restricting the development of domestic auto industry. Low efficiency of resource allocation and lack of social organizational resources are the significant problems which the domestic automotive parts suppliers face in their restructuring and upgrading process and also the important issues which the service science research faces in our country.Service science is the interdisciplinary and systematic study on service with scientifically formal method, which is in the rise phase at present. The innovation and breakthrough of the study on Service-embedded manufacturing model, one of the specific content of manufacturing service science at present, is expected to promote the social division of labor and futher enhance the sustainable competitiveness of manufacturers. Applying service science concepts and methodology in the optimization of resource allocation and social organization construction of auto parts suppliers, is expected to improve the competitive advantage of auto parts suppliers. Thus the paper has important practical significance and value.The meaning of auto parts supplier's service is defined based on value net thought. That is, what the suppliers provide is not just products but also a kind of whole supply solution. Suppliers transform to service-embedded manufacturers, providing service to down-stream manufacturers as well as other enterprises in the same industry. Service firms provide services for intermediate production.By comparing the development trend and experience of domestic and foreign auto parts enterprises, the object of auto parts supplier's service game have be defined(that is auto parts suppliers and production services companies). The content of auto parts suppliers'service including logistics, finance, R & D, marketing, outsourcing, information and so on is defined.The evolutionary game is chosen as the main research methods in this paper after analyzing the shortage of traditional methods of game theory like needing the hypothesis of "Rational man" and equilibrium etc. From the perspective of evolutionary game theory,an overview of the possible relationships and network configuration path between suppliers and serive enterprises is outlined. And thus the overall service game and optimization model , which is"one information sharing mode"+"three service modes"and named"1+3"service operation system , is proposed based on service-embedded auto parts suppliers. The overall research framework on the optimization of the auto parts supplier's value network is formed.Within the construction of the"1+3"service operation system, cost information selective sharing model established on modified Lotka-Volterra model is set up from the perspective of evolutionary game theory, which lays the foundation for the design of coorperation mechanism between suppliers and service firms. And three service game modes are set up one by one, which are horizontal service game optimization mode based on Cournot and Lotka-Volterra model between two homogeneous auto parts enterprises, collaborative management optimization mode of auto parts providers'task alliance based on task utility model and the Shapley distribution model and providers'value chain optimization mode with service alliance embedded based on Lotka-Volterra model Shapley distribution model. the"1+3"service operation system comprehensively explains the service operation mechanism and modes,which provides a theoretical basis for the optimization of the auto parts supplier's value network .Finally, some logistics service practice of an automotive parts group is analyzed which testifies the three modes proposed in the paper. The results show that the service game and optimization model based on service-embedded auto parts suppliers is helpful to improve resource utilization efficiency through fine specialized division of labor among suppliers and service enterprises and thus provides new construction way for the optimization of auto parts value net.
