The Research On Information Evolution Game Of Supply Chain In Supply-Hub Model Based On Cloud Platform

Supply-Hub, which is a distribution center, is located between suppliers and manufacturers. It manages supply materials for enterprises in upstream by a variety of operations and delivers supply material on time according to the enterprises'production plan in downstream. Supply-Hub supply chain operation mode alleviates the "bullwhip effect" phenomenon to some extent, but because of simple information transfer mode, weak ability of processing data, the backward technique and other reasons in existing Supply-Hub supply chain platform, the information transfer is still affected by information delay and information distortion, information management has become a difficulty of Supply-Hub supply chain management; At the same time,due to no strong motivation of information sharing, serious phenomenon of "free rider"and " ego ism" and information asymmetry, the traditional game analysis has been unable to provide substantive suggestions.The cloud computing provides a possible solution to the problem of Supply-Hub supply chain information synergy, Supply-Hub operators can ensure the timeliness and accuracy of information synergy in the upstream and downstream through the cloud platform; At the same time, through the analysis all kinds of information synergy strategies and its influencing factors of Supply-Hub supply chain enterprises and cloud service providers, which has important significance to Supply-Hub supply chain information synergy.The paper is from the perspective of Supply-Hub supply chain information synergy. firstly, according to realistic background and literature review, The paper points out the study value; Secondly,the paper analyzes the present situation and existing problems of traditional information platform and enterprises game, and on the basis of the feasibility analysis, the paper builds a cloud platform, and describes the process of building and information synergy; third, the paper respectively establishes information evolution game model between cloud service providers and Supply chain enterprise group in the cloud platform, and between Supply chain enterprise groups, and then discusses equilibrium strategy scheme of evolution and the key factors influencing groups information synergy, and do the numerical simulation to analysis results of two evolutionary game model through MATLAB software and proves the correctness of the model analysis results. Finally, according to the results of the analysis of the evolutionary game model and from the point of view of Supply-Hub supply chain enterprise and cloud platform service provider, the paper puts forward the strategy of promoting Supply-Hub supply chain information synergy.
