网络信息体系双层异质相依网络模型鲁棒性

网络信息体系(networked information system of system, NISoS)是构建新体制下联合作战武器装备体系的基础支撑。针对NISoS结构模型单一和鲁棒性评估指标粗糙等问题, 首先基于复杂相依网络理论分析了体系结构特征和级联衰退过程, 构建了体系双层异质相依网络模型(two-layer heterogeneous interdependent network model, THINM); 其次借鉴现代循环作战理论提出基于信息驱动链网融合(C-SDI link number and network scale, C-SDILNNS)指标的网络信息体系鲁棒性评估方法; 最后对比分析了不同失效策略和评估指标下的网络信息体系鲁棒性能。仿真结果表明, THINM能够较好反映网络信息体系结构特征, 通过C-SDILNNS指标可以精细刻画多种攻击方式和攻击强度下的体系鲁棒性。

Robustness of two-layer heterogeneous interdependent network model for networked information system of system

The networked information system of system(NISoS)is the foundation for the construction of the new weapon and equipment system.On the basis of the complex interdependent network theory,this paper analyzes the structural characteristics and the process of cascading failure for NISoS,and then constructs the two-layer heterogeneous interdependent network model(THINM).Secondly,referring to the modern cycle warfare theory,a robustness assessment method based on information driven link number and network scale(C-SDILNNS)is proposed.Finally,the performance of NISoS under different failure strategies and evaluation indexes is compared and analyzed.The simulation results show that the THINM can reflect the characteristics of the NISoS network architecture,and the robustness under various attack modes and intensity can be described by C-SDILNNS.
