摘　　要：为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重要度的方法。通过实例考证表明,改进的粗糙集重要度计算方法具有普适性,解决了在文献[3]中提出而没有解决的问题。We have improved the concept of attribute significance degree and have given a method to determine the single attribute signifi- cance degree for combinational attribute significance d based on rough set. A case is used to prove that the improved method is more practicable and the problem of paper [3] is solved.

关 键 词：粗糙集 属性重要度 权重
