Fuzzy Semi-Numbers and Their Elementary Arithmetic With a Medical Case Study
International Journal of Computational Intelligence Systems, 2018 A new methodology for processing non-normal fuzzy sets is proposed. To break the predominant constraint on normality of fuzzy numbers the concept of fuzzy semi-numbers is introduced Then it is shown how to generalize operations defined on fuzzy numbers ...

Representing Fuzzy Numbers for Fuzzy Calculus [PDF]
, 2007 In this paper we illustrate the LU representation of fuzzy numbers and present an LU-fuzzy calculator, in order to explain the use of the LU-fuzzy model and to show the advantage of the parametrization. The model can be applied either in the level-cut or in generalized LR frames.

Shannon entropy-based approach for calculating values of WABL parameters
Journal of Taibah University for Science, 2020 In the application phase of the fuzzy theory, it is an obvious advantage to have a valuable defuzzification. The defuzzification method that we deal with in this work is a flexible, adaptable and multi-purpose method.
