摘　　要：改进属性重要度概念,给出了一种基于粗糙集理论的单属性重要度和组合属性重要度结合的确定属性权重的方法及其具体操作步骤。通过实例说明,改进的粗糙集权重计算方法具有普适性,权重计算更合理。The attribute significance degree concept is improved in this paper, it proposes an improved method of attri-bute weight assignment of signal and attribute significance degree based on rough set. A case is used to prove that improved weighting method is more to fit practice and make weight more reasonable than before.

关 键 词：粗集理论 属性重要度 权重
