地铁网络中断下韧性评估及修复策略OA北大核心

With the development of China's urban metro,the resilience of the metro system facing natural disasters,emergencies and other disturbance events has been a matter of great concern.To evaluate and optimize the resilience of metro networks,this paper first analyzed the topology in-depth,proposed a network performance function that took the connectivity level and redundancy level into account comprehensively,and constructed a metric for network resilience.Then,in the interruption scenario,the station restoration scheduling problem aiming at resilience optimization was investigated,and a genetic algorithm was adopted to solve the model and specify the construction plan for construction teams.Finally,the Taipei Metro was used as a case study to test the effectiveness of the proposed method.The results show that after multiple station failures,the network performance decreases due to connectivity level and redundancy level.Under duration constraints,the optimal restoration strategy model can rationalize the construction plan to maximize metro network resilience.If the conditions are satisfied,extending the construction period will help further enhance the optimal network resilience.This case study provides a useful reference for urban metro network planning and improving the resilience of metro networks.
