Abstract:

In modern combat， nodes differ significantly from the single-function nodes of the past， evolving towards multi-function integration. To address issues such as the characterization of node function diversity， the dynamic reconfiguration of system models， and realistic simulation of enemy network analysis in current node importance evaluations of combat systems， a dynamic reconfiguration model based on unit attributes for the enemy’s network is proposed. The concept of tactical weight is introduced， and multi-function integration of nodes and edges is achieved through attribute induction and attribute assignment. A method and algorithm for calculating the dynamic reconfiguration of network effectiveness are presented. Taking into account the actual operational context and efficiency， the node attack cost is incorporated， and a node importance evaluation model based on the contribution rate to system network effectiveness is proposed. In simulation experiments， node importance is evaluated using seven different metrics， including node effectiveness index， degree centrality， and betweenness centrality， under various spatiotemporal conditions. The decline in network effectiveness after network strikes is also analyzed. The simulation results demonstrate that the proposed method enables dynamic reconfiguration of the network post-attack， reflecting the network’s strong robustness and confirming the validity of the proposed algorithm.

摘要：

现代作战中的节点已区别于过去的功能单一化节点，正朝着多功能一体化发展。针对当前作战体系节点重要度评估中存在的节点功能多样性刻画、体系模型动态重构性构建、对蓝方网络分析现实性模拟等问题，面向蓝方体系网络建立了基于单位属性的动态重构体系网络模型，引入战术权值概念，并通过属性归纳与属性赋值的方式完成节点多功能一体化的构建与边的构建，提出了体系网络效能的动态重构计算方法和算法。考虑实际作战情况与作战效率，引入节点攻击代价，提出了基于单位属性的体系网络效能贡献率的节点重要度评估模型。在仿真模拟实验中，对比了不同时空状态下，按节点效能指数、度中心性、介数中心性等7种方式对节点进行重要度评估，并对网络进行打击后的网络效能的下降程度。仿真结果显示，所提方法实现了网络打击后的动态重构，体现了实际网络的强鲁棒性，验证了所提算法的合理性。
