Oriented Fuzzy Numbers vs. Fuzzy Numbers [PDF]
Mathematics, 2021 A formal model of an imprecise number can be given as, inter alia, a fuzzy number or oriented fuzzy numbers. Are they formally equivalent models? Our main goal is to seek formal differences between fuzzy numbers and oriented 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

An Approximation of Fuzzy Numbers Based on Polynomial Form Fuzzy Numbers
International Journal of Analysis and Applications, 2018 In this paper, we approximate an arbitrary fuzzy number by a polynomial fuzzy number through minimizing the distance between them. Throughout this work, we used a distance that is a meter on the set of all fuzzy numbers with continuous left and right ...

A new approach for ranking of intuitionistic fuzzy numbers [PDF]
Journal of Fuzzy Extension and Applications, 2020 The concept of an intuitionistic fuzzy number (IFN) is of importance for representing an ill-known quantity. Ranking fuzzy numbers plays a very important role in the decision process, data analysis and applications. The concept of an IFN is of importance

Nearest fuzzy number of type L-R to an arbitrary fuzzy number with applications to fuzzy linear system [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2023 The fuzzy operations on fuzzy numbers of type L-R are much easier than general fuzzy numbers. It would be interesting to approximate a fuzzy number by a fuzzy number of type L-R.
