Cascading Model of Infrastructure Networks based on Complex Network
The paper focuses on the cascading failure phenomenon of infrastructure networks. A new cascading model is proposed to analyze the cascading failure characteristics of the systems. Based on the model, we present a good evaluation method of node importance to identify the key nodes which may cause cascading failures of infrastructure networks. Finally, the damage degree of infrastructure networks considering cascading failures is investigated through our cascading model. The simulation results indicate the validity and practicality of the proposed model. The research is helpful to protect the key components of infrastructure networks and decrease the network vulnerability. Meanwhile, the proposed method provides valuable reference to many actual networks in nature.
