Performance analysis of metro network and research on minimizing resilience loss recovery strategy
In order to better analyze the performance of the metro network and optimize its recovery strategy under the disturbance state,a complex network-based metro network performance analysis method is used and a recovery strategy to minimize the resilience loss is proposed.In view of the complex network characteristics of the metro network,the Space L topology method is used to deal with the metro network,and the complex network theory is applied to calculate the basic parameters of each station in the network,including the degree of the network,the average path and the network efficiency,etc.Next,the network efficiency is used as the performance index to solve the resilience loss of each station according to the resilience theory,and the station recovery sequence is determined by combi-ning with genetic algorithm.Finally,taking Fuzhou city as an example,the complex network charac-teristics of its metro network are analyzed and perturbation simulations are performed to compare the recovery effects of the minimized resilience loss recovery strategy with those of the random recovery strategy in the case of multiple station failures.The results show that the minimized resilience loss recovery strategy can keep the performance of the metro network at a better level during the recovery period when multiple metro stations are subject to perturbation failure,and the recovery effect is signif-icantly better than the random recovery strategy with uncertainty.
