Model and Analyzeof Cascading Failure of Nanjing Logistics Network
In order to improve the reliability of the urban logistics network and the ability to cope with emergencies and reduce the risk caused by cascade failure,the impact of cascading failure on the logistics network was analyzed by taking the relative size of the maximum connectivity subgraph as the reliability measurement index of the logistics network in Nanjing.By adopting different attack strategies,the influence of factors such as the amount of information between nodes and the degree of nodes on network performance was analyzed,and the cascading failure phenomenon of logistics network in Nanjing was simulated to observe the change of network reliability.The results show that in the face of random attacks,the larger the weight coefficient,the lower the network reliability;for deliberate attacks,the network reliability is higher when the weight coefficient is large;the larger the number of nodes,the greater the impact of its failure on network reliability.
