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.

Fuzzy Interpolation with Extensional Fuzzy Numbers [PDF]
Symmetry, 2021 The article develops further directions stemming from the arithmetic of extensional fuzzy numbers. It presents the existing knowledge of the relationship between the arithmetic and the proposed orderings of extensional fuzzy numbers—so-called S-orderings—and investigates distinct properties of such orderings.

Solving fuzzy multiobjective linear bilevel programming problems based on the extension principle [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2021 Fuzzy multiobjective linear bilevel programming (FMOLBP) problems are studied in this paper. The existing methods replace one or some deterministic model(s) instead of the problem and solve the model(s).

Fuzzy Distance of Trapezoidal Fuzzy Numbers [PDF]
Advances in Intelligent Systems Research, 2006 Fuzzy distance is applied on data analysis, classification, and product positioning analysis widely. In this paper, We introduce a fuzzy distance by using graded mean integration representation of generalized fuzzy number and the span of fuzzy number, We also discuss the distance of the linguistic data of “greater or less than x” and “about x”.

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. For this purpose, we examine algebraic structures composed of numerical spaces equipped with addition, dot ...
