多维约束下指挥网络节点重要度的评估方法

摘要

A method for evaluating the node importance of command network was presented to solve the problem of information interaction with outside and self-operating mechanism which is not taken into ac-count in the traditional methods.Topology structure and operational mission and command mode and node attribute were taken into account.The method of structure importance was presented based on global and local importance of topology network,the method of dependence of mission-to-node was given based on task decomposition and feature subset,the method of dependence of command mode-to-node was presented by considering the impact of deleting nodes,and the method of attribute importance was given based on in-terval number.Finally,the evaluation algorithm was presented.Illustrative example was presented in which the data of node importance was given with multiple constraints.The results show that the impor-tance of the same node or nodes with the same structure importance is different in different operational mission and command mode,and that the data from the proposed algorithm can be more comprehensive compared to a single method,which shows the superiority of this method.%针对一般节点重要度评估方法没有考虑指挥体系网络自身运行机制及与外界交互的问题，从拓扑结构、作战任务、指挥方式、节点属性4个维度研究指挥节点的重要度评估方法。考虑节点在拓扑网络的全局和局部重要性给出结构重要度计算方法，基于任务分解和节点功能子集的形成给出作战任务对节点依赖度计算方法，通过删除节点对指挥质量造成的影响给出指挥方式对节点依赖度计算方法，并给出基于区间数的节点属性重要度的计算方法。最后提出指挥节点的综合评估方法并设计了具体案例，得出节点在四维约束下的重要度定量评估数据。结果表明，同一节点或结构重要度相同的节点在不同任务和指挥方式下综合重要度差异明显，与单一方法相比，提出的综合算法所得数据能更全面反映指挥节点的重要程度，说明该算法具有优越性。
