Abstract:

In this paper we present rough approximation methods based of Atanassov’s structures referred to as IF sets. In contrast to some existing approaches to the problem, where the unit interval [0,1] and suitable fuzzy fuzzy connectives were used, we will use some class of residuated lattices as basic algebraic structures. In the signature of these algebras we have coun­terparts of two main classes of fuzzy implications. We show that, depending on fuzzy implications determining lower rough approximations, we can ex­press degrees of weak and strong certainities and possibilities of membership (resp. non-membership) of an element to a set.
