摘　　要：现代战争中,军事指挥信息系统在态势感知、控制决策等方面起到了至关重要的作用。将指挥信息系统视为复杂网络,从中识别出重要节点进行保障,是提升指挥信息系统抗毁能力的重要手段。针对k-Shell算法存在的节点重要度,区分精度低及忽略指挥信息系统末端节点数量多,重要性难以区分的缺陷,提出基于k-Shell改进的GMMDD关键节点识别算法。该方法基于接近中心性进行节点重要度初始化,并采用重力模型计算节点的局部影响力,引入耗尽度评估已剥离节点的贡献。仿真结果表明:GMMDD在仿真指挥系统网络上能够区分大量末端节点间的重要性,抗毁伤研究进一步证明了GMMDD识别方案的优越性。Military command information systems play a crucial role in such areas as situational awareness and control decision-making,etc.Treating command information systems as complex networks and identifying key nodes for support is an important means to enhance.Their invulnerability against destruction.Addressing the limitations of the k-Shell algorithm,which include low precision in distinguishing node importance in ignoting the significance of numerous end nodes within command information systems,and difficulties in distinguishing the importance an improved key node identification algorithm called GMMDD(gravity model-based mixture degree decomposition is proposed).This method is based on the initialization of node importance with closeness centrality,and the gravity model is employed to calculate the local influence of nodes.Furthermore,an exhaustion assessment is introduced to evaluate the contributions of detached nodes.The simulation results indicate that GMMDD effectively distinguishes the importance among a significant number of end nodes in a simulated command system network.The study on invulnerability against destruction further validates the superiority of the GMMDD identification scheme.
