Possibilistic max-mean dispersion problem
Volume 19, Issue 5 , September and October 2022, Pages 1-15
Abstract
The Max-Mean Dispersion Problem comprises selecting a subset of elements from a set while maximising the average of a measure of dispersion. We usually compute this measure of dispersion based on some distance metric between the elements of the candidate set. However, in real-world applications, this ... Read MoreAre multidimensional RDM interval arithmetic and constrained interval arithmetic one and the same?
Volume 19, Issue 5 , September and October 2022, Pages 17-34
Abstract
This article discusses the comments made by some scientists that multidimensional interval arithmetic (MIA) is the same as constraint interval arithmetic (CIA) and multidimensional fuzzy arithmetic (MFA) is the same as constraint fuzzy arithmetic (CFA). Both types of arithmetic are briefly presented ... Read MoreBest-possible bounds on the set of copulas with a given value of Gini's gamma
Volume 19, Issue 5 , September and October 2022, Pages 35-45
Abstract
In this note, pointwise best-possible (lower and upper) bounds on the set of copulas with a given value of the Gini's gamma coefficient are established. It is shown that, unlike the best-possible bounds on the set of copulas with a given value of other known measures such as Kendall's tau, Spearman's ...

Volume 19, Issue 5 , September and October 2022, Pages 47-61
Abstract
This paper deals with the issues of the finite-time synchronization (FTS) for a class of fractional-order fuzzy Cohen-Grossberg neural networks (FOFCGNNs) with time delay. Based on the finite-time stability theory, fractional-order Razumikhin theorem and applying fractional-order differential inequalities ... Read MoreL-R representation of TA fuzzy arithmetic and its application to solving fuzzy equations
Volume 19, Issue 5 , September and October 2022, Pages 63-78
Abstract
Fuzzy arithmetic with standard methods such as the extension principle and$\alpha $-cut lead to restricted possibilities for solving fuzzy equations.The procedures to find a solution to a fuzzy equality with these methodsrequire strong assumptions and high computation costs. Among severalapproaches dealing ... Read MoreAn extended MABAC method based on prospect theory for multiple attribute group decision making under probabilistic uncertain linguistic environment
Volume 19, Issue 5 , September and October 2022, Pages 79-94
Abstract
Cyber security is a hot topic in recent years and one of the main performances in the decision-making is the choice of cyber security service providers (CSSPs). For enterprises and government units, the selection of appropriate NSSPs needs to be measured and evaluated from multiple perspectives, which ... Read MoreCharacterizations of L-order L-convex spaces
Volume 19, Issue 5 , September and October 2022, Pages 95-109
Abstract
In this paper, the concepts of $L$-enclosed $L$-order space, $L$-order $L$-concave space, $L$-internal $L$-order space and $L$-order $L$-convex filter are introduced. The main results are:(1) the categories of $L$-order $L$-convex spaces, $L$-enclosed $L$-order spaces, $L$-order $L$-concave spaces and ... Read MoreSupervisory adaptive interval type-2 fuzzy sliding mode control for planar cable-driven parallel robots using Grasshopper optimization
Volume 19, Issue 5 , September and October 2022, Pages 111-129
Abstract
Design of an adaptive supervisory fuzzy sliding mode control for a planar cable-driven parallel robot is aided in this paper. The fuzzy logic controller is proposed to generate the switching control signal without occurring the chattering problem. For this purpose, an adaptive mechanism is suggested ... Read MoreDiagonal conditions and uniformly continuous extension in $\top$-uniform limit spaces
Volume 19, Issue 5 , September and October 2022, Pages 131-145
Abstract
We study suitable diagonal conditions for $\top$-uniform limit spaces. A dual diagonal condition is shown to be a suitable axiom for uniform regularity. We characterize this regularity concept by closures of $L$-sets. We apply all these diagonal axioms and prove an extension theorem for uniformly continuous ... Read MoreAn improvement in integrating clustering method and neural network to extract rules and application in diagnosis support
Volume 19, Issue 5 , September and October 2022, Pages 147-165
Abstract
Most of chronic liver diseases without suitable treatment will lead to cirrhosis of the liver, eventually progressing to liver cancer. Thus, early diagnosis is very important in detecting the liver diseases and suggesting the treatment at the right time. A useful model that effectively predicts the patient's ... Read MoreHFC: Data clustering based on hesitant fuzzy decision making
Volume 19, Issue 5 , September and October 2022, Pages 167-181
Abstract
In a clustering task, choosing a proper clustering algorithm and obtaining qualified clusters are crucial issues. Sometimes, a clustering algorithm is chosen based on the data distribution, but data distributions are not known beforehand in real world problems. In this case, we hesitate which clustering ...
