Resilience evaluation of container shipping network based on cascade failure

In order to evaluate the dynamic resilience of container shipping network, this paper constructs a resilience evaluation system considering both operational capacity and recovery capacity. In order to consider the dynamic propagation of network failure node traffic, designs two node load distribution methods, namely port skipping over and port replacement, and four different load distribution ratios when port skipping over are selected. Based on this, constructs a cascade failure model of container shipping network. Taking RCEP regional container shipping network as an example, this paper explores the changes of network resilience under single point attack, deliberate attack and random attack, and the influence of different parameters on network resilience. The results show that once Singapore Port fails, it will have the greatest impact on network resilience. Comprehensive distribution strategy and local load distribution strategy can reduce the risk of cascading failure propagation after the failure of high node strength ports and small ports respectively, which is conducive to maintaining network resilience. In addition, appropriately increasing the capacity of the port and choosing port skipping over can also effectively slow down the decline rate of network resilience.
