电信网可靠性是电信网运行中最重要的指标之一．在分析电信网可靠性指标体系的基础上，提出了进行可靠性综合评价的思路．为解决评价中的核心问题——各指标评价的权重，采用ＢＰ算法得到了各指标与基准指标的相关关系，从而确定了指标的权重．最后利用一级干线网证明了评价方法的有效性 Telecom network reliability is one of the most important indicators of the operation of the telecommunications network. On the basis of analyzing the reliability index system of telecommunication network, the idea of ​​comprehensive reliability evaluation is put forward. In order to solve the core problem of evaluation - the weight of each index evaluation, the correlation between each index and the benchmark index is obtained by BP algorithm, so as to determine the weight of the index. Finally, the use of a trunk network to prove the effectiveness of the evaluation method
