Vulnerability Evaluation of Beijing Urban Rail Transit Network Operation System Under Fire Disturbance
In order to evaluate the vulnerability of overall Beijing urban rail transit network operation system under fire dis-turbance,and entirely improve the capacity of fire accident risk prevention and control,based on the vulnerability three-ele-ment theory,a four-layer structure vulnerability evaluation index system applied for network operation system was construc-ted.According to core businesses,the index system was described by dividing into four subsystems:traffic organization,passenger service,power supply and environmental control.The vulnerability index focusing on each subsystem relating to fire emergency accident development was decomposed from three dimensions:exposure,sensitivity and adaptability separate-ly.Analytic hierarchy process(AHP)and comprehensive fuzzy evaluation method are used for empirical study.The research results show that by using this index system to evaluate,the overall vulnerability of network operation tends to be average be-tween average and high,which is consistent with the actual situation,and main vulnerability improving advices are indicated as well,according to the results of evaluation.Through above research,management method and scientific basis have been provided for relevant business departments to continuously evaluate and optimize operational fire safety measures from the perspective of the overall system vulnerability.
