Attribute Reductions in Intuitionistic Fuzzy Information Systems Based on Dominance Relations
Abstract: Many methods based on the rough set theory to deal with information systems have been proposed in recent years. However, intuitionistic fuzzy information systems have not been investigated yet. In this paper, dominance relations are firstly defined in intuitionistic fuzzy information systems and decision tables, and then the concepts of attribute reductions and relative reductions are proposed. Practical approaches to compute all reductions and relative reductions are presented by introducing of discernibility matrix and dis-cernibility function.
