Cascading Failure Model and Method of Supply Chain Based on Complex Network

This paper focused on the cascading failure of supply chain network.A node importance evaluation method is employed to analyze the cascading failure characteristics.Then the critical nodes which may cause cascading failure in the whole network are identified.Finally,the damage degree of cascading failure measured by largest connected component is tested using the largest workload tolerance parameter.The simulation results indicate the validity and practicality of this method.
