On the notion of fuzzy dispersion measure and its application to triangular fuzzy numbers

Information Fusion, 2023
In this paper, based on the analysis of the most widely used dispersion measure in the real context (namely, the variance), we introduce the notion of fuzzy dispersion measure associated to a finite set of data given by fuzzy numbers. This measure is implemented as a fuzzy number, so there is no loss of information caused by any defuzzification.

An Approach to the Total Least Squares Method for Symmetric Triangular Fuzzy Numbers

Mathematics
The total least squares method has a broad applicability in many fields. It is also useful in fuzzy data analysis. In this paper, we study the method of total least squares for fuzzy variables. The regression parameters are considered to be crisp. First,

Fuzzy Unconstrained Optimization Problems with Triangular Fuzzy Numbers

IOP Conference Series: Materials Science and Engineering, 2020
Abstract In this paper, we consider an unconstrained optimization problem with fuzzy valued functions. Using generalized Hukuhara differentiability of fuzzy functions in Newton’s method, we obtain an optimal solution of fuzzy unconstrained optimization problem without transforming to crisp equivalent form. Numerical examples are provided
