Evaluation Method for Command Node Importance Based on Weighted Network Model

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 node importance is an important aspect of research on reliability and invulnera-bility of command networks.A method of evaluating the relative importance of the important node of weigh-ted networks by using node importance evaluation matrix is presented based on defining node importance in-cidence matrix.The position information of the node and the relation with the neighbor nodes’importance contribution are taken into account.In accordance with the reliance of task on community,the algorithm flow of importance is designed,and the algorithm is used to analyze the importance of typical networks.Ex-periments show the algorithm is verified to be feasible and effective.
