摘要
网络化指挥信息系统是现代信息化条件下体系作战的基础支撑和重要枢纽.在分析网络化指挥信息系统结构功能基础上,构建带权重的双层相依网络,提出一种考虑节点过载和节点修复的级联失效模型,并在基于节点权重的负载重分配策略基础上构造基于节点相似、基于节点剩余容量和综合分配3种改进型策略.以"LB演习"数据为样本,针对攻击方式、负载重分配策略和网络性能参数对网络抗毁性影响展开研究.仿真结果表明:物理层重要节点对网络性能影响最为关键,并且网络性能会在蓄意攻击下产生突变现象;改进的3种策略,特别是综合分配策略,能够显著提升网络抗毁性,网络性能参数能够在一定范围内大幅提升网络抗毁性,避免大规模级联失效现象.
The networked command information system is the basic support and important hubs for system operations under the conditions of modern informationization.Based on the analysis of the structure and function of the networked command information system,this paper constructs a double layer dependent network with weights,proposes a cascade failure model considering node overload and node repair,and constructs three improved strategies based on the weightbased load redistribution strategy.Taking the"LB manoeuvre"data as a sample,the effects of attack mode,load redistribution strategy and network performance parameters on network invulnerability are studied.The simulation results show that the important nodes of the physical layer are the most critical to the network performance,and the network performance will be abrupt under the deliberate attack.The improved three strategies,especially the comprehensive redistribution strategy,can significantly improve the network invulnerability.And in a certain range,the network invulnerability is greatly improved.
