Abstract: Two new intuitionistic fuzzy operators of level type are introduced and some of their properties are studied. They are related to the degree of uncertainty of a given intuitionistic fuzzy set. Geometrical interpretations onto the intuitionistic fuzzy interpretation triangle are provided.
Keywords: Intuitionistic fuzzy set, Level operator, Uncertainty.
AMS Classification: 03E72.
