A Parametric Interval Approximation of Fuzzy Numbers
International Conference on Advanced Computer Systems, 2015In this paper we present a parametric formulation of interval approximation of fuzzy numbers. It is based on a more complex version of generalized Trutschnig et al. distance. General conclusions are showed and particular cases are studied in details.

Approximation of Fuzzy Numbers Using Max-Product Operators
2018Here we study quantitatively the approximation of fuzzy numbers by fuzzy approximators generated by the Max-product operators of Bernstein type and Meyer-Koning and Zeller type. It follows Anastassiou, Approximation of Fuzzy Numbers by Max-Product Operators, 2017, [1].

RETRACTED: Approximation of fuzzy complex numbers by the form x ˜ + i y ˜
Journal of Intelligent & Fuzzy Systems, 2022It plays an important role in the calculation of fuzzy numbers using some special fuzzy numbers to approximate general fuzzy numbers in fuzzy analysis, similar to fuzzy complex analysis.

Approximations of Fuzzy Numbers by 2-2-step Type Fuzzy Numbers
2021 2nd International Conference on Artificial Intelligence and Information Systems, 2021In this paper, an approximation method is given using step type fuzzy number to approximate a general fuzzy number. Say concretely, for any given general fuzzy number, a group of calculation formulas are obtained for the coordinates of the left end point of the left step and the right end point of the right step of the 2-2-step type fuzzy number that ...

Approximation of intuitionistic fuzzy numbers by trapezoidal intuitionistic fuzzy numbers
Journal of Intelligent & Fuzzy Systems, 2017The notation of extended intuitionistic fuzzy number is introduced and the representation of the weighted extended trapezoidal intuitionistic approximation of an intuitionistic fuzzy number is given in this paper. The problem related to aggregation is addressed about approximating the given intuitionistic fuzzy numbers or aggregating the given ...
