%X 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.
