摘要
基于复杂网络上灾害蔓延动力学理论,在考虑了生命线网络结构特征的基础之上,建立生命线网络级联失效模型。利用相邻模糊标度法进行权重分配,计算各种节点连接方式的关联度。从生命线网络中各节点的关联度入手,考察生命线网络级联失效规模受网络结构特征和各节点连接方式的影响情况。实验结果表明,不同节点连接形式下,网络级联失效规模明显不同,说明节点关联度是造成生命线系统灾害蔓延的重要原因。
The establishment of lifeline network cascading failure model based on the theory of disaster spreading dynamics on complex networks takes into account the structural features of lifeline system.This paper distributes weights with the method of adjacent fuzzy scaling to calculate the node degree of correlation in various connection types.The influence of structural features and tapes of node connections to cascading failure scale researched from the perspective of node relevance degree in the lifeline network.Simulation results show that the network cascading failure scale is significantly different with different connection types,indicating that node relevance degree is a significant reason for disaster spreading in the lifeline system.
