摘　　要：研究了一类基于粗集属性取模糊值的不完备信息系统的知识获取方法.给出粗模糊属性值信息系统的一种表示方法,采用模糊集思想,构造这类系统的模糊不可分辨关系,并研究这类信息系统的知识获取算法,并以一个实例,说明这种算法的有效性.This paper studies a method for knowledge acquisition of information systems with fuzzy sets attributes based on rough set. Firstly a expressing method of this kind incomplete information systems is introduced, and the fuzzy indiscernibility relation of information systems is established. The algorithm of implementation is also discussed, by which method the knowledge hidden in this system can be expressed in the form of decision rules, and an example is given to verify its efficiency.

关 键 词：模糊粗糙集 信息系统 模糊不可分辨关系
