Near Fixed Point Theorems in the Space of Fuzzy Numbers
Mathematics, 2018 The fuzzy numbers are fuzzy sets owning some elegant mathematical structures. The space consisting of all fuzzy numbers cannot form a vector space because it lacks the concept of the additive inverse element.

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 ...

Ranking fuzzy numbers using preference ratio: A utility function approach [PDF]
Decision Science Letters, 2013 Ranking fuzzy numbers is one of the most important phases in any decision making process in fuzzy environments. In most cases, we deal with fuzzy numbers in the field of evaluating alternatives with fuzzy information or linguistic variables.

Solution of generalised type – 2 Fuzzy boundary value problem
Alexandria Engineering Journal, 2021 In this article, we proposed a new representation of type-2 fuzzy numbers called generalized type-2 fuzzy numbers. Dirichlet, Neumann and Mixed kind of boundary value problem have been considered with the boundary condition as generalized type-2 fuzzy ...
