International Journal of Computational Intelligence Systems, 2020 This paper studies numerical solutions for fuzzy initial value problems, where the initial conditions are given by interactive fuzzy numbers. The fuzzy solution is given by a numerical method that employs the arithmetic of interactive fuzzy numbers and ...

Equivalence class in the set of fuzzy numbers and its application in decision-making problems
International Journal of Mathematics and Mathematical Sciences, 2006 An equivalence relation is defined in the set of fuzzy numbers. In a particular equivalence class, arithmetic operations of fuzzy numbers are introduced.

On Fuzzy Arithmetic Operations: Some Properties and Distributive Approximations [PDF]
We analyze a decomposition of the fuzzy numbers (or intervals) which seems to be of interest in the study of some properties of fuzzy arithmetic operations and, in particular, in the analysis of fuzziness, of shape-preservation (symmetry) and ...

An LU-fuzzy calculator for the basic fuzzy calculus [PDF]
The LU-model for fuzzy numbers has been introduced in [4] and applied to fuzzy calculus in [9]; in this paper we build an LU-fuzzy calculator, in order to explain the use of the LU-fuzzy representation and to show the advantage of the parametrization ...

Representing fuzzy numbers for fuzzy calculus [PDF]
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
