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

Mathematical Problems in Engineering, Volume 2011, Issue 1, 2011., 2011
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 of complicated decision table, respectively.

Monotonic variable consistency rough set approaches

, 2009
We consider probabilistic rough set approaches based on different versions of the definition of rough approximation of a set. In these versions, consistency measures are used to control assignment of objects to lower and upper approximations. Inspired by
