Risk communication and simulation of supply chain

Abstract

Based on the idea of virus transmission the paper constructs the risk model of Supply Chain, and then set the threshold of natural disasters rate, disease rate, cure rate, infection rate and the cooperation among the supply chain enterprises. The paper use Matlab to simulate the transmission model. The research shows that the number of cooperative relations between supply chain enterprises is determined by the number of core enterprises of the industry in a relatively stable industry background. In addition the infection rate, cure rate and infection rate have a certain relationship with the number of supply chain cooperation. According to the structure of simulation, this paper puts forward some management suggestions that the risk and credit risk of core enterprise in supply chain should be paid more attention, the supply chain core enterprise certification qualification should be examined strictly, the formation of Supply Chain Partnership should be encouraged.
