指挥节点重要度评估是研究指挥网络可靠性和抗毁性的重要内容。通过定义加权网络节点重要度贡献矩阵,提出了一种利用节点重要度评价矩阵确定加权网络关键节点的相对重要度的方法,该方法能充分考虑节点的位置信息、邻接节点的重要度贡献关系;结合作战任务对社区的依赖度,设计了节点全局重要度评估算法,并利用该算法对典型网络节点重要度进行了分析,结果表明算法有效、可行。
The evaluation of command node importance is an important part of studying the reliability and invulnerability of command network. By defining the contribution matrix of importance degree of weighted network nodes, a method of using node importance evaluation matrix to determine the relative importance of key nodes in weighted networks is proposed. The method can give full consideration to the location information of nodes and the contribution of the importance of adjacent nodes. According to the dependency degree of warfare mission on the community, a node global importance evaluation algorithm is designed and used to analyze the importance of typical network nodes. The results show that the algorithm is effective and feasible.
