Part of the Studies in Fuzziness and Soft Computing book series (STUDFUZZ, volume 317)


In this chapter, we present a method for approximate evaluation of Zadeh’s Z-numbers using category sets of probability distributions corresponding to similar certainty measures.



We are very grateful to Prof. Lotfi A. Zadeh for his mentorship and encouragement and to Ms. Ixel Chavez for all her help.
