A Trust Model of Hybrid P2P Supply Chain Based on Interest Group

This paper analyzed the existing problems in the supply chain system,proposed a trust model of hybrid P2P supply chain based on interest group in order to improve the confidence crisis in the supply chain among enterprises.The model uses interests similarity to characterize the services behavior similarity in the preferences fields for enterprises,and adpots trust and credibility attenuation mechanism to achieve the trust evaluation of node in the supply chain.The experimental simulation results and comparison show that,the model could build efficient,reliable,trust cooperation between enterprises in supply chain,prevent effectively the moral hazard,realize information sharing and resources integration for each node in supply chain,and improve efficiency.
