基于TOPSIS的装备保障网络节点重要性综合评价方法

Synthesis Evaluation Method for Network Node Importance in Equipment Support Based on TOPSIS

针对复杂网络拓扑结构分布的不均匀性导致单一指标难以准确反映网络中节点重要程度的问题,将网络的每个节点作为1个方案,将节点重要性评价指标作为描述方案的属性,从节点度指标、介数指标、删除指标、接近中心性指标和子图指标5个方面,采用改进的逼近理想解排序法(Technique for Order Preference by Similarity to an Ideal Solution,TOPSIS)对网络节点的重要性进行综合评价,计算每个方案到理想方案的接近度,并按由大到小的顺序进行排序,得出节点重要性综合评价结果。最后,以某装备保障网络实例对该方法的可行性和有效性进行了验证。

According to the problem of the inhomogeneity of the complex network topology will lead to a failure that a single index cannot accurately reflect the degree of node importance in the network,each node in the network is taken as one program,the evaluation index of node importance are taken as the program attribute in this paper. The improved method of Technique for Order Preference by Similarity to an Ideal Solution（ TOPSIS） is used to evaluate the node importance from five indicators such as node degree,betweenness,deleting index,close to center and sub-graph. The approximate degree of each scheme to the ideal scheme is calculated and sorted according to the order from large to small,and the comprehensive evaluation results of node importance are obtained. Finally,the feasibility and effectiveness of the proposed method are verified by an example of an equipment support network.
