摘要：
This paper presents a new method of approximating fuzzy decision concepts by using fuzzy condition concepts. The rough approximation of fuzzy concepts is investigated based on the idea of abstract approximation space in rough set theory. A weak approximation space and a CN-fuzzy rough set are defined in fuzzy decision systems by means of a family of fuzzy condition concepts, from which the values of lower and upper approximation of each object may be determined. Therefore, a decision making about fuzzy concept is obtained.
