Analysis and Simulation Research of Supply Chain Robustness Considering the Risk Transmission

This paper mainly researched the complex supply chain robustness considering the risk infection, using the methods of complex network and REPAST simulation. First, this paper carried on an in-depth analysis on the infection of supply chain risk. Moreover, based on the characteristics of complex static topology of the network connection, this paper put forward a Leon Jeff matrix and its Euclidean norm as a measure of the supply chain robustness indicators. Then, the robustness performance of the supply chain system under risk infection was analyzed with the simulation tool of Repast S. Finally, a conclusion was drawn that the influences on supply chain robustness are different when node enterprises (points) and their relationship (edges) are at risk in the supply chain network.
