Resilience Network Structure Based on Hybrid Optimization Indexes
To improve network resilience,the grid uniformity is proposed,and combined with natural connectivity and maximum connected subgraph to optimize the network design.First,randomly distributed nodes are generated;then,under the constraint of the total length of the path,the hybrid indexes are regarded as the optimization target for the edges connection;finally,network structure is optimized by the genetic algorithm.In the random strike test,the number of nodes of the average maximum connected subgraph of the algorithm is 8 times of that of the natural connectivity algorithm and 4 times of that of the maximum connected subgraph algorithm.
