Complex Network Restoration Dynamics Method Considering Continuity between Cascading Failure and Restoration
To help the network system restore with reasonable investment as soon as possible after cascading failure,using coupling map lattice as the basis of the restoration dynamics model,and the failure state and coupling coefficient under the cascade failure are taken as the input of the restoration dynamics.By further adding the external restoring force and the internal coupling to form the restoration dynamics method.The restoration effect is improved by 46.7%,47.9%and 66.7%respectively compared with three groups of network restoration methods without considering continuity.In addition,the simulation results on six different networks show that this method can fit the real restoration scene,overcome the differences in network level,scale,network construction methods and so on.Specifically,in the three-layer transportation network,the marginal contribution rate of the initial restoration ratio to the restoration degree is 26.8%,and when the coupling coefficient of restoration is 0.5 and 10%of the nodes are restored for the first time,the restoration degree of the network is as high as 86.4%.The proposed restoration dynamics method can effectively describe the restoration process of various networks.
