摘　　要：评估指标体系的构建是一个复杂的系统工程,优化是其中重要的一步。指标相关性和冗余指标的存在一直都是体系构建工作中的重要问题。采用相关系数赋权方法降低指标间的相关性对评估结果造成的影响,并采用粗糙集属性约简方法减少冗余指标,从而完成评估指标体系的优化。采用该方法对通信网可靠性指标体系进行了相应优化,降低了指标体系的相关性与冗余度。The construction of evaluation index system is complex system engineering,and optimization is an important step of it.Index correlation and existing of redundant index are the important problem during index system building.The effect come from index correlation to evaluation results has been reduced by the method of correlation factors,and redundant index has been reduced by Rough Set method, and then the evolution index system has been optimized.The index system of communication network has been optimized by the method,the index correlation and index redundancy have been reduced.
