In this paper, we introduce four kinds of rough approximations for a given intuitionistic fuzzy set. Keywords Fuzzy set, Intuitionistic Fuzzy Set, Rough Approximations
In this paper the Archimedean property and the nilpotency of t-norms on the lattice LI is investigated, where LI is the underlying lattice of interval-valued fuzzy set theory (Sam...
Abstract. Paraconsistent intuitionistic fuzzy set is an extension of intuitionistic fuzzy set or interval-valued fuzzy set. It relaxes the requirement that t + f ≤ 1, where t is ...
