In different scientific directions, there are many mathematical techniques like the fuzzy set (𝔽-set) (Zadeh, 1965) and the intuitionistic fuzzy set (IF-set) (Atanassov & Atanassov, 1999) for the solution of difficult situations having various types of uncertainties. The fuzzy set-like technique is for the truth value of an item belonging to a certain description space, and the second is for both the truth and false values of an item with the property of dependency on each other.
