Abstract
In this paper a novel approach for simplifying the obtained if–then rules from decision table by rough set based methods is proposed This approach can extract main features of objects in different decision classes by remarkable degrees Using the proposed method two real world decisionmaking problems are studied The first one is for analyzing the main features of Japanese industries The second is for anatomizing the life situations of senior citizens in Japan The analysis results show that the proposed method is powerful for piecing out the main features of decision classes in the decision table which has many attributes and objects The obtained main features can provide deep insight into the situations of objects and are useful for making a decision in the real world
