摘　　要：可靠性综合评价对研究光纤保护通道有着重要作用。阐述了可靠性综合评价方法,简要描述了其基本步骤。介绍了层次分析法和模糊层次分析法的基本原理。并以某省电力光纤保护通道的2006到2007年度数据为实例,引用模糊层次分析法,建立指标模型,用Matlab软件编写仿真程序,计算指标权重,按层次进行排序,得到可靠性的综合评价结果。由综合评价结果可以看出可靠性指数的综合增长情况,并可具体看出各个指标的变动情况,从而为采取相应措施加以改善提供依据。Reliability comprehensive evaluation is very important for optical fiber protection channel.This paper describes the method of reliability comprehensive evaluation and the basic steps of evaluation method in brief.It also introduces the basic principle of analytic hierarchy process （AHP） and fuzzy analytic hierarchy process.Then taking annual data from 2006 to 2007 in one province on electric power optical fiber protection channel as an example,the paper uses fuzzy analytic hierarchy process to make index model,design MATLAB program simulation and calculate the index weight,then sort them according to the level of model to obtain the result of reliability comprehensive evaluation. On the basis of the reliability comprehensive evaluation,the comprehensive growing situation of reliability index and the variation condition of each index can be seen clearly.So it could provide some useful evidence for some improving measures.
