Abstract: An interval-valued intuitionistic fuzzy set (IVIFS) whose universe is an intuitionistic fuzzy set (IFS) is introduced here and its basic properties are discussed. One step further, it is discussed the case when the universe represents an IVIFS itself. Again, some basic properties of the so constructed object are formulated and proved. Ideas for further research are presented.
Keywords: Interval-valued intuitionistic fuzzy set, Intuitionistic fuzzy set, Universe.
