Developments in the Wake of the Theory of Possibility

  • Ellen Hisdal


The theory of possibility has introduced new concepts into the theory of fuzzy subsets of multidimensional universes, and has clarified some of the concepts which were already in use. It has also contributed to our seeing the theory of fuzzy sets in a wider perspective. Boolean sets, max-min fuzzy sets and probabilistic sets can be considered as special cases of a more generalized class of fuzzy set systems.
