 abstract={In many applications we have a set of objects together with their properties. Since the available information is often incomplete and/or imprecise, the true knowledge about subsets of objects can be determined approximately only. In this paper we present a fuzzy generalization of two relation-based operations suitable for set approximations. Main properties of these operations are presented. We show that under specific assumptions these operations coincide with fuzzy rough approximation operators.},
