摘要
对网络的形成机制、几何性质、演化规律以及网络结构分析、行为预测和控制的研究产生了复杂网络学科,其中关于复杂网络级联失效过程的研究一直受到研究人员的关注。文中提出一种更符合实际网络的两变量非线性负载容量模型来解决复杂网络的级联失效问题。通过在4个不同的网络上进行仿真,验证了所提模型的有效性,发现该模型能够更好地抵御级联失效。实验还发现,所提模型在获得较高鲁棒性的情况下具有更好的性能,且投资成本较小。
The study of network formation mechanism,geometric property,evolution rules,network structure analysis,behavior prediction and control gives rise to the discipline of complex network,and cascade failure process of complex network has always been concerned.This paper presents a non-linear load capacity model with two variable parameters,which is more suitable for real network,to solve the cascading failures problem of complex networks.Simulations on four different networks verify the effectiveness of the proposed model.The results show that the model can better defend against cascading failures,and has a lower investment cost and a better performance in the case of higher robustness.
