Invulnerability simulation analysis of complex logistics networks based on cascading failure

By the analysis of characteristics of complex logistics networks,a simulation model based on cascading failure for its invulnerability was proposed.In this model,the intensity and distribution of network traffic was controlled by an α-index and a β-index,respectively.The variety of invulnerability was simulated under random failures and intentional attacks on different networks.Result shows that the invulnerability performance declines rapidly when the network traffic is increased.Furthermore,the distribution of network traffic also has a strong impact on the invulnerability performance.
