Read MorePartially continuous pretopological and topological operators for intuitionistic fuzzy sets
Volume 17, Issue 2 , March and April 2020, Pages 1-15
Abstract
In this paper, pretopological and topological operators are introduced based on partially continuous linear transformations of the membership and non-membership functions for intuitionistic fuzzy sets. They turn out to be a generalization of the topological operators for intuitionistic ... Read MoreUlam-Hyers-Rassias stability for fuzzy fractional integral equations
Volume 17, Issue 2 , March and April 2020, Pages 17-27
Abstract
In this paper, we study the fuzzy Ulam-Hyers-Rassias stability for two kinds of fuzzy fractional integral equations by employing the fixed point technique. Read MoreFuzzy based efficient drone base stations (DBSs) placement in the 5G cellular network
Volume 17, Issue 2 , March and April 2020, Pages 29-38
Abstract
Currently, cellular networks are one of the essential communication methods for people. Providing proper coverage for the users and also offering high-quality services to them are two of the most important issues of concern in cellular networks. The fifth-generation cellular communication networks can ... Read MoreSingle cycle supply chain coordination model for fuzzy stochastic demand of perishable items
Volume 17, Issue 2 , March and April 2020, Pages 39-48
Abstract
Market demand of the perishable bakery products are volatile. Hence, demand of such items are random variable. The most appealing demand distribution of such items is lognormal demand distribution. Using historical data, the parameters of lognormal distribution are obtained. But, there is ... Read MoreSwitching fuzzy modelling and control scheme using T-S fuzzy systems with nonlinear consequent parts
Volume 17, Issue 2 , March and April 2020, Pages 49-65
Abstract
This paper extends the idea of switching T-S fuzzy systems with linear consequent parts to nonlinear ones. Each nonlinear subsystem is exactly represented by a T-S fuzzy system with Lure’ type consequent parts, which allows to model and control wider classes of switching systems and also reduce ... Read MoreFuzzy decision making in testing hypotheses: An introduction to the packages ``FPV" and ``Fuzzy.p.value" with practical examples
Volume 17, Issue 2 , March and April 2020, Pages 67-77
Abstract
This paper reviews and compares two R packages ``FPV" and ``Fuzzy.p.value".These packages are designed for testing hypotheses in a fuzzy environment using a fuzzy $p$-value based approach.In fact, the packages ``FPV" and ``Fuzzy.p.value" propose some useful functions for testing hypotheses when the data ... Read MoreA fuzzy capacitated facility location-network design model: A hybrid firefly and invasive weed optimization (FIWO) solution
Volume 17, Issue 2 , March and April 2020, Pages 79-95
Abstract
Facility location-network design (FLND) problem, which determines the location of facilities and also communication links between the demand and facility nodes, is arisen from the combination of the facility location and network design problems. This paper deals with fuzzy capacitated facility location-network ... Read MoreHyperspace of a fuzzy quasi-uniform space
Volume 17, Issue 2 , March and April 2020, Pages 97-114
Abstract
The aim of this paper is to present a fuzzy counterpart method of constructing the Hausdorff quasi-uniformity of a crisp quasi-uniformity. This process, based on previous works due to Morsi \cite{Morsi94} and Georgescu \cite{Georgescu08}, allows to extend probabilistic and Hutton $[0,1]$-quasi-uniformities ... Read MoreInterval number ranking method considering multiple decision attitudes
Volume 17, Issue 2 , March and April 2020, Pages 115-127
Abstract
Many interval number ranking methods cannot representthe different attitudes of decision makers with different riskappetites. Therefore, interval numbers are expressed in the RectangularCoordinate System (RCS). After mining the interval numbers in the RCS,the Symmetry Axis Compensation Factor, which ... Read MoreA new family of (A, N)-implications: Construction and properties
Volume 17, Issue 2 , March and April 2020, Pages 129-145
Abstract
This paper deals with a new family of (A, N)-implications that derived from fuzzy negation and continuous monotone function, and some properties, like the left neutrally, the exchange principle, the ordering property and the laws of contraposition, of the proposed family of (A, N)-implications ... Read MoreSeveral new results based on the study of distance measures of intuitionistic fuzzy sets
Volume 17, Issue 2 , March and April 2020, Pages 147-163
Abstract
It is doubtless that intuitionistic fuzzy set (IFS) theory plays an increasingly important role in solving the problems under uncertain situation. As one of the most critical members in the theory, distance measure is widely used in many aspects. Nevertheless, it is a pity that part of the existing distance ... Read MoreContinuity of super- and sub-additive transformations of continuous functions
Volume 17, Issue 2 , March and April 2020, Pages 165-168
Abstract
We prove a continuity inheritance property for super- and sub-additive transformations of non-negative continuous multivariate functions defined on the domain of all non-negative points and vanishing at the origin. As a corollary of this result we obtain that super- and sub-additive transformations of ... Read MoreProbit and nested logit models based on fuzzy measure
Volume 17, Issue 2 , March and April 2020, Pages 169-181
Abstract
Inspired by the interactive discrete choice logit models [Aggarwal, 2019], this paper presents the advanced families of discrete choice models, such as nested logit, mixed logit, and probit models to consider the interaction among the attributes. Besides the DM's attitudinal character is also taken ... Read MoreA new approach to rank the decision making units in presence of infeasibility in intuitionistic fuzzy environment
Volume 17, Issue 2 , March and April 2020, Pages 183-199
Abstract
Data envelopment analysis (DEA) is a linear programming based methodology to determine the relative performance efficiencies of homogeneous decision making units (DMUs). In real world applications, some input and output datas do not possess crisp/fuzzy essence but they possess intuitionistic fuzzy (IF) ... Read Morepersian translate 17-2 APRIL 2020
