摘　　要：复杂网络中失效节点或边产生的级联效应,严重时将导致整个网络瘫痪。初始负载的定义方式对级联故障模型分析具有重要影响。综合考虑采用度定义缺乏拓扑信息及介数定义计算量过大,充分利用网络的拓扑信息和节点的邻域信息,首次提出了基于局部熵的初始负载定义方式。典型的复杂网络级联故障模型实例,验证了所提局部熵定义的有效性。Cascading failures caused by failed nodes or edges in the network may lead to the paralysis of the whole network.The definition of initial load has a very important impact on the analysis of cascading failure model.In this paper,considering the lack of topological information brought by degree and the huge computation brought by betweenness centrality,we make full use of the topological information as well as neighbors’information of nodes and firstly propose the initial load definition based on local entropy.Some typical examples about cascading failures in the complex networks demonstrate the effectiveness of proposed definition based on local entropy.
