| 摘 要： | 在BBV模型的基础上提出了一个具有有限承载能力(即节点强度S和边权W均有限)的加权网络演化模型--LLBBV模型.理论分析和数值仿真均表明,这个模型生成的网络的节点度分布、强度分布和边权分布均具有幂律分布的特征,幂律指数不随S和W变化而变化,而且在蓄意攻击而引发的相继故障中,LLBBV模型比BBV模型的表现更好,其鲁棒性更强.

| Abstract: | A new weighted evolving network model (LLBBV model) with limited carrying capacity (both node strength S and link weight W are limited) based on BBV model is proposed. Theoretical analysis and numerical simulation show that the distribution of node degree, node strength and link weight are power-law after the evolution in LLBBV model, the power-law exponent will not change when the limited carrying capacity changes. LLBBV model performs better and has a better robustness in compare with BBV model in the process of cascading failures triggered by deliberate attacks. |
