Abstract :
In this paper, we take a GL-quantale as the truth value table to study a new rough set model|L-valued fuzzy rough
sets. The three key components of this model are: an L-fuzzy set A as the universal set, an L-valued relation of A and
an L-fuzzy set of A (a fuzzy subset of fuzzy sets). Then L-valued fuzzy rough sets are completely characterized via
both constructive and axiomatic approaches.
