Abstract
A fuzzy relation R between elements from two finite universes is considered. Granules of R created by pairs of subsets from the two universes are evaluated. A rough extension of R based on a generalized rough set model is proposed. This extension allows us to introduce the notions of R-related sets, strongly R-related sets and R-compatible sets. R-related sets can be further used for evaluations of R-relationship between partitions of elements from two related universes. © Springer-Verlag Berlin Heidelberg 2010.
