Discernable matrix and its application in decision rules

Decision rules acquisition is based on attribute reduction, and Skowron’s discernable matrix is one of the most important methods of core finding and reduction. Basing on Skowron’s discernable matrix researching attribute reduction of decision system, this paper puts forward an algorithm for acquisition of decision rules and its application with Skowron’s discernable matrix as a base, and examples are given to demonstrate the effectiveness of the obtained result.
