| 摘 要： | 本文介绍了粗糙集和模糊粗糙集的上下近似。并且利用模糊粗糙上下近似算子，论述了在不完备模糊信息系统中知识获取的一种方法。应用这种方法能够让隐藏在不完备模糊信息系统中的知识，以决策规则的形式表示出来。最后给出了一种实现算法和实例。

| Abstract: | This paper introduces the lower and upper approximations operator of rough sets and fuzzy sets. By using fuzzy rough lower and upper approximation operators,this paper provides a method of knowledge acquisition is incomplete fuzzy information systems. The knowledge hidden in the incomplete fuzzy information system can be expressed in the form of decision rules using the method. The algorithm of implementation is also discussed, and an example is given. |
