Type-2 Fuzzy Control of a Bioreactor [PDF]

open access: yes, 2009
—In this paper the control of a bioprocess using an adaptive type-2 fuzzy logic controller is proposed. The process is concerned with the aerobic alcoholic fermentation for the growth of Saccharomyces Cerevisiae a n d i s characterized by ...

Type-2 Fuzzy Soft Sets and Their Applications in Decision Making

open access: yesJournal of Applied Mathematics, 2012
Molodtsov introduced the theory of soft sets, which can be used as a general mathematical tool for dealing with uncertainty. This paper aims to introduce the concept of the type-2 fuzzy soft set by integrating the type-2 fuzzy set theory and the soft set

Type-2 Fuzzy G-Tolerance Relation and Its Properties

open access: yesInternational Journal of Analysis and Applications, 2017
In this short communication we generalize the definition of type-2 fuzzy tolerance relation and consequently the type-2 fuzzy G-tolerance relation in type-2 fuzzy sets. The type-2 fuzzy G-tolerance relation helps in finding the type-2 fuzzy G-equivalence

Equivariant Fields in an $SU({\cal N})$ Gauge Theory with new Spontaneously Generated Fuzzy Extra Dimensions

open access: yes, 2016
We find new spontaneously generated fuzzy extra dimensions emerging from a certain deformation of $N=4$ supersymmetric Yang-Mills (SYM) theory with cubic soft supersymmetry breaking and mass deformation terms.

A big bang-big crunch optimization based approach for interval type-2 fuzzy PID controller design [PDF]

open access: yes, 2013
In this paper, we will present a big bang-big crunch optimization (BB-BC) based approach for the design of an interval type-2 fuzzy PID controller. The implemented global optimization algorithm has a low computational cost and a high convergence speed ...

INTUITIONISTIC FUZZY ORIGINATED TYPE-2 FUZZY AHP

open access: yesInternational Journal of the Analytic Hierarchy Process, 2018
Intuitionistic fuzzy sets (IFS) proposed by Atanassov (1983, 1986) are a generalization of ordinary fuzzy sets. They incorporate the degree of hesitation which is defined as 1 minus the sum of membership and non-membership degrees. Type-2 fuzzy sets were first introduced by Zadeh (1975) as an extension of the concept of an ordinary fuzzy set.
