Supply Chain Trust Mechanism Modeling And Simulation

With the development of market economy, many enterprises, begin to corporate withother enterprise in the form of supply chain alliance increase their own core competitiveability. Supply chain enterprise according to their own union core capability of the processto realize the division of the production, storage and sales of goods. Effective supply chainmanagement can bring agility and enterprise low cost competitive advantage for everysupply chain nodes, and improve the overall competitiveness of supply chain. However,because of the mass nodes of supply chain alliance, and the Complex structure ofenterprise’s league. Trust crisis frequently happen between enterprise nodes. the trust isthe important prerequisite for the supply chain alliance to meet its goals function.As the supply chain alliance presents a large-scale enterprise node, nets chain, timedomain, cross region across the characteristics of the distribution of the supply chain, thealliance for complex network performances chain system. Previous supply chain trustresearch mainly focuses on economic laws, game theory perspective, statistics, and so on,and lack of supply chain system building trust model. This paper studies the supply chaintrust by adopting distributed system modeling method.First，This paper analysed the structure of supply chain and the connotation of thesupply chain trust, the former research on supply chain mainly come from the sociologyand psychology knowledge. they analysis the connotation of supply chain,the way tomaintain and transfer, and its influence factors.Secondly this paper analysed the chain structure of the supply chain alliance and modelthe supply chain by agent technology. With reference on the knowledge sociology of trustthis paper divide the trust between enterprise nodes as the fusion of direct and indirecttrust and established calculation model separately based on bayesian network andevidence theory of supply chain trust.Finally numerical simulation of trust model was made to verify the robustness of thedynamic characteristics in the environment of high, medium and low three differentdegree of malicious attacks the simulation results show that the model has good dynamicand robustness.
