Rough Set Approach to Approximation Reduction in Ordered Decision Table with Fuzzy Decision

In practice, some of information systems are based on dominance relations, and values of decision attribute are fuzzy. So, it is meaningful to study attribute reductions in ordered decision tables with fuzzy decision. In this paper, upper and lower approximation reductions are proposed in this kind...
