Abstract:

To comparative study the cascading failure mechanism and coupling properties for interdependent networks of hazardous materials transportation, the model is proposed for interdependent networks of hazardous materials transportation which including physical network, service network and correlative- chain, the cascading failure model is also established. Regarding the average size of network cascading failure based on node degree as the measure of invulnerability. Simulation results show that, in the same number of failure nodes, the conductivity between physical network and service network is different, and the number of failure nodes for physical network is bigger than the service network' s; the interdependent networks invulnerability can be improved by changing the network model parameters, and enhancing the network model parameters of service network is much more effective than physical network' s, etc. These results can provide theoretical support for risk identification and emergency management of interdependent networks of hazardous materials transportation.
