摘要: 为定量描述城市轨道交通灾害事件间的传播关系,帮助决策者在发生灾害事件时作出更加科学的判断,采用危险与可操作性分析(HAZOP)法,提出城轨系统灾害事件集的提取方法;基于城轨事故历史数据,通过共现矩阵的构造和Jaccard指数的计算,构建灾害链有向网络模型;然后,针对给出的灾害链网络,结合复杂网络统计指标,定量评价其节点和边的重要程度。利用历史事故数据,验证模型和评价方法。结果表明:所建灾害链网络模型能客观反映灾害事件间的传播关系;网络的边和节点的重要度评价结果与实际情况相符。

Abstract: To quantitatively describe the communication relationships between urban rail transit disaster events,help decision makers make more scientific judgments on disaster events,the HAZOP method was used to develop a method for extracting the disaster event set of the urban rail system,based on the historical data on urban rail accidents,a disaster chain oriented network model was built through the construction of a co-occurrence matrix and the calculation of Jaccard index,and values of importance of nodes and edges in a given disaster chain network were evaluated quantitatively on the basis of the statistical indicators of complex networks.Finally,the model and the evaluation method were verified by using historical accident data.The results show that the disaster chain network model can objectively reflect the propagation relationship between disaster events,and that the importance evaluation results of the edges and nodes of the network are consistent with the actual situation.

Key words: urban transit system, complex network theory, disaster event extraction, disaster chain network construction, network evaluation
