【摘要】：为探索体系作战信息流转级联失效的特点规律,抽象了作战信息流转的层级网络结构,建立了基于任务约束的级联失效模型。提出由物理层和逻辑层组成的信息流转分层网络结构,分析了网络层间的级联失效影响关系;引入任务协作因子改进节点介数计算方法,根据作战任务动态生成信息流转层级网络结构,考虑节点功能属性和信息交互方向,设计负荷重分配策略及失效判定条件,采用平均失效规模度量级联失效影响。以空中进攻作战为例进行仿真分析。结果表明,节点具有较小初始负荷及容量的网络,更易产生快速显著的级联失效;失效节点类型不同,所产生级联失效的规模和持续时间具有较大差异。仿真结果验证了模型的可行性与有效性,可为网络结构优化设计、安全防护等提供有益借鉴。
[Abstract]:In order to explore the characteristics of cascade failure of operational information flow, the hierarchical network structure of operational information flow is abstracted, and a cascade failure model based on mission constraints is established. The information flow hierarchical network structure composed of physical layer and logical layer is proposed, and the cascade failure relationship between network layers is analyzed. The task collaboration factor is introduced to improve the calculation method of node meshes. According to the operational tasks, the hierarchical network structure of information flow is generated dynamically, and the load redistribution strategy and failure judgment conditions are designed considering the function attributes of nodes and the direction of information interaction. The average failure scale is used to measure the cascade failure effect. Take the air attack as an example to carry on the simulation analysis. The results show that nodes with small initial load and capacity are more likely to produce rapid and significant cascading failures, and the scale and duration of cascading failures vary greatly with different types of failure nodes. The simulation results verify the feasibility and validity of the model, and can provide useful reference for the optimization design of network structure and safety protection.
