级联失效指挥控制网络抗毁性研究

Cascading Failure Resilience Research in Command and Control Networks

针对现有的级联失效分析对指挥控制网络的作用和机理研究较少,导致抗毁性评估指标难以量化的问题,从复杂网络的角度出发,运用NK复杂网络理论,引入容量-负载模型,建立指挥控制网络级联失效模型,并通过演化仿真的方法定量分析网络参数和修复策略对指挥控制网络抗毁性的影响。实验结果表明,该模型能较好地刻画指挥控制网络级联失效过程,并挖掘指挥控制网络级联失效内在机理,可为指挥控制网络抗毁性分析与优化提供支撑。

In response to the limited research on the role and mechanism of cascading failure analysis in command and control networks,which complicates the quantification of resilience evaluation indica⁃tors,a perspective from complex networks is adopted.The NK complex network theory is applied,the capacity load model is introduced,and a cascading failure model for command and control networks is established.Through evolutionary simulation,the influence of network parameters and repair strategies on the resilience of command and control networks is quantitatively analyzed.The experimental results demonstrate that the model effectively characterizes the cascading failure process within command and control networks,explores the inherent mechanism of cascading failures,and provides support for the analysis and optimization of their resilience.
