突发事件下地铁网络韧性评估及恢复策略研究
Resilience Assessment and Recovery Strategy of Metro Network under Emergencies
摘要
Abstract
Under emergencies,the global efficiency of the network based on passenger flow weighting was proposed through the comprehensive consideration of the two perspectives of metro network topology and passenger flow.Based on complex network theory,a metro network topology was established,and network characteristic indicators were analyzed.A resilience assessment method for metro networks based on the global efficiency of the network and an optimization model for metro network recovery timing based on genetic algorithms were proposed.By using the Xi'an Metro Network as the research object,the optimal recovery strategy for failed stations in the Xi'an Metro Network was proposed based on the recovery timing schemes under five different recovery strategies.The results indicate that:① Under two distinct emergencies,the recovery strategy based on genetic algorithms proves to be the optimal approach.② The impact of different recovery strategies under linear station failures during emergency 1(backflow of floodwater)is more pronounced.③ Under the same recovery strategy,the network resilience of emergency 1 surpasses that of emergency 2(violent incident).关键词
