摘要:

针对指挥信息系统级联失效研究中存在的结构建模简单和攻击方式单一的不足，提出指挥信息系统双层耦合网络模型，在此基础上设置不同的攻击方式，分析系统的级联失效特性.首先，根据指挥信息系统体系结构和层级网络理论，构建了由通信网络和功能网络构成的双层耦合网络模型，并提出节点重要度指标；其次，设置实体打击、赛博攻击和混合攻击三种攻击方式，以及不同的攻击强度对指挥信息系统进行攻击，分析其级联失效机理；最后，仿真分析表明，双层耦合网络模型能够反映指挥信息系统的结构特征，基于该模型能够分析指挥信息系统在多种攻击方式和攻击强度下的级联失效特性.

Abstract:

Aimed at the disadvantages of simple construction and attack mode in study of the Command Information System (CIS) cascading failure, a CIS bi-layer coupled network model is constructed. We analyze some characteristics of CIS cascading failure by setting different attack modes based on it. Firstly, the model is constructed by coupling communication network and function network of CIS architecture, and the node weightiness parameter is proposed based on the multilayer network theory. Secondly, by setting three attack modes and defining attack intensity, we analyze cascading failure mechanism of the bi-layer coupled network model. Lastly, simulation results show that the bi-layer coupled network model can reflect characteristics of CIS network structure, and based on this model, we can analyze cascading failure mechanism of CIS under conditions of setting different attack modes and attack intensities.
