In this paper, we introduce four kinds of rough approximations for a given intuitionistic fuzzy set. Keywords Fuzzy set, Intuitionistic Fuzzy Set, Rough Approximations
Bipolarity has not been much exploited in the spatial domain yet, although it has many features to manage imprecise and incomplete information that could be interesting in this dom...
This paper deals with interval-valued fuzzy sets and I-fuzzy sets, Atanassov's intuitionistic fuzzy sets. They are treated in a systematic way as two, formally equivalent, na...
