Information Measures Over Intuitionistic Four Valued Fuzzy Preferences

This paper studies the meaning of fuzzy preference under the light institionistic fuzzy sets. Intuitionism is revisted and intuitionistic fuzzy prefrerence relations are defined. A linguistic interpretation of strict and weak fuzzy preference is then developed where indecision can be explicity analyzed with the help of a bilattice. Uncertainty is finally examined as a measure of ignorance associated to the intensity value of thhe preferece predicate, where some information measures are applied over its complete structure.
