| 摘 要： | 针对现实网络上的负载重分配规则常常是介于全局分配与最近邻分配、均匀分配与极端非均匀分配的特点, 提出了一种可调负载重分配范围与负载重分配异质性的复杂网络级联失效模型, 并分析了该模型在无标度网络上的级联失效条件. 解析与仿真结果表明, 合理调节负载重分配的范围、负载重分配的异质性可以显著提高复杂网络抵御级联失效的抗毁性.

| Abstract: | In order to deal with the problem that the redistribution rule of real networks always lies between global shared rule and nearest neighbor shared rule or between even shared rule and extremely heterogeneous rule, a novel cascading failure model of complex networks is proposed. It can tune the load redistribution range and the distribution heterogeneity of extra load. Numerical simulation and analytic results show that the model can achieve better robustness against cascading failure than previous model by adjusting the redistribution range and heterogeneity. |
