摘　　要：针对传统AHP层次分析法在光纤通信安全性评价方面存在主观性,导致评价结果不准确的问题,在研究AHP层次评价的基础上,提出一种基于云模型的电力通信网络安全评估模型。首先对云模型综合指标评估算法的原理和步骤进行了研究,从而解决数据定性与定量互转中存在的模糊性和不确定性;针对传统指标体系构建中不同专家存在的知识冲突问题,引入D_S理论,从而得到相对权重,进而提高权重计算的客观性。最后,利用MATLAB软件对上述综合模型进行编程,并通过对比验证了上述模型在电力信息通信网络安全评价的优势。Based on the traditional AHP AHP subjectivity exists in the optical fiber communication safety evaluation,which result in the problem of inaccurate,in the study of AHP levels on the basis of the evaluation,put forward an evaluation model of electric power communication network security based on cloud model.Firstly,the principle and steps of comprehensive index cloud model evaluation algorithm is studied,so as to solve the qualitative and quantitative data exist mutual conversion in the fuzziness and uncertainty of knowledge;for conflicts between different experts construct in traditional index system,introducing D-S theory,in order to get the relative weight,and improve the objectivity of weight calculation.Finally,the MATLAB software is used to program the integrated model,and the advantages of the model in the security evaluation of power information communication network are verified by comparison.
