摘　　要：针对目前耦合网络级联失效的研究方法仅限于单个关系的问题,根据多子网复合复杂网络模型构建复合网络,结合多种关系研究了复合网络级联失效问题,考察在不同影响因素下,网内关系和加载关系对网络鲁棒性的影响。研究结果表明,网内关系和加载关系共同影响着网络级联失效的过程及规模,复合网络中两子网拓扑结构不同,网内关系对网络的影响不同;加载关系强度占比越大,网络鲁棒性越强。关系强度比例对网络故障规模存在决定性影响。Aiming at the current research methods about coupling networks cascading failure are only limited to the problem of single relationship.A composite network is built based on multi-subnet composite complex network model.Combining multi relationships,the problem of composite network cascading failure is studied.It mainly investigates the influence of intra-network relationship and loading relationship on network robustness under different influencing factors.Research results show that the process and scale of network cascade failure are influenced by intra-network relationship and loading relationship.The topological structure of the two subnets in the composite network is different,intra-network relationship have different effects on the network.The higher the proportion of the strength of the loading relationship,the stronger the robustness of the internet is.The relationship strength ratio has a decisive influence on the scale of network failure.
