A novel technique for solving two-person zero-sum matrix games in a rough fuzzy environment [PDF]

open access: yesYugoslav Journal of Operations Research, 2022
This study proposes a novel way to deal with uncertainty in a two-person zero-sum matrix game with payoffs expressed as fuzzy rough numbers. Complete and reasonable solutions to these types of games are obtained.

Fuzzy Best Simultaneous Approximation of a Finite Numbers of Functions [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2019
Fuzzy best simultaneous approximation of a finite number of functions is considered. For this purpose, a fuzzy norm on $Cleft (X, Y right )$ and its fuzzy dual space and also the  set of subgradients of a fuzzy norm are introduced.

The Best Approximation of Generalized Fuzzy Numbers Based on Scaled Metric

open access: yesJournal of Mathematics, 2022
The ongoing study has been vehemently allocated to propound an ameliorated α-weighted generalized approximation of an arbitrary fuzzy number. This method sets out to lessen the distance between the original fuzzy set and its approximation.

The Arithmetic Operator of Fuzzy Regular Prismoid Numbers and Its Application to Fuzzy Risk Analysis

open access: yesInternational Journal of Computational Intelligence Systems, 2021
We devote to study the arithmetic operator of fuzzy regular prismoid numbers as well as the degree of similarity between fuzzy regular prismoid numbers, and then the arithmetic operator and the degree of similarity are applied in risk analysis.
