摘　　要：提出了一种基于粗糙集理论的规则提取的新方法。利用粗糙集理论直接生成确定性基本决策规则和不确定性基本决策规则,形成信息系统的基本决策规则库。同时,证明了任一确定性规则都可以由确定性的基本决策规则生成。最后,给出了规则提取的算法描述,分析了算法的性能。A new method about extracting rules based on rough sets theory was proposed. Both the certainty and uncertainty basis decision rules were extracted directly by using rough sets theory, and then formed libraries of decision rules of the information system. Moreover, we proved that any certain rule can be obtained by some certain basis decision rules. Finally, the description of algorithm was given and the efficiency of the algorithm was analyzed as well.
