为提高电力通信网关键节点识别准确性,文章设计一种基于TOPSIS的电力通信网关键节点识别方法。首先构建电力通信网节点重要度水平评价体系,使用度中心度、紧密中心度和中介中心度三个指标对指标的重要度进行衡量,然后采用TOPSIS方法计算重要度指标的初始矩阵,根据指标权重计算结果,确定指标体系最优解与最劣解,以求解电力通信网络节点中各个指标标准化向量的相对接近度,完成电力通信网关键节点识别。实验证明,设计的基于TOPSIS的电力通信网关键节点识别方法识别准确度较高。

To improve the accuracy of key node identification in power communication network,a method of key node identification based on TOPSIS wasdesigned.Firstly,the evaluation system of the importance level of the electric power communication network nodes wasconstructed.Using degree centrality,compactness centrality and intermediary centrality,the importance of indicators was measured.Then,TOPSIS method is used to calculate the initial matrix of the importance index.The optimal solution and the worst solution of the index system were determined by the result of index weight calculation.In order to solve the relative closeness of each index standardized vector in the power communication network nodes was solved,to complete the identification of the key nodes of the power communication network.Experiments showed that the key node identification method based on TOPSIS designed in this paper had high accuracy.
