ON THE FUZZY SET THEORY AND AGGREGATION FUNCTIONS: HISTORY AND SOME RECENT ADVANCES
Volume 15, Issue 7 , September and October 2018, Pages 1-12
Abstract
Several fuzzy connectives, including those proposed by Lotfi Zadeh, can be seen as linear extensions of the Boolean connectives from the scale $\{0,1\}$ into the scale $[0,1]$. We discuss these extensions, in particular, we focus on the dualities arising from the Boolean dualities. These dualities allow ...

Volume 15, Issue 7 , September and October 2018, Pages 13-21
Abstract
Super- and sub-additive transformations of aggregation functions have been recently introduced by Greco, Mesiar, Rindone and \v{S}ipeky [The superadditive and the subadditive transformations of integrals and aggregation functions, {\it Fuzzy Sets and Systems} {\bf 291} (2016), 40--53]. In this article ... Read MoreTREND-CYCLE ESTIMATION USING FUZZY TRANSFORM OF HIGHER DEGREE
Volume 15, Issue 7 , September and October 2018, Pages 23-54
Abstract
In this paper, we provide theoretical justification for the application of higher degree fuzzy transform in time series analysis. Under the assumption that a time series can be additively decomposed into a trend-cycle, a seasonal component and a random noise, we demonstrate that the higher degree fuzzy ...

Volume 15, Issue 7 , September and October 2018, Pages 55-66
Abstract
In this study, we consider two different inequivalent formulations of the logistic difference equation $x_{n+1}= \beta x_n(1- x_n),\ \ n=0,1,..., $ where $x_n$ is a sequence of fuzzy numbers and $\beta$ is a positive fuzzy number. The major contribution of this paper is to study the existence, uniqueness and ... Read MoreTRANSPORT EQUATION WITH FUZZY DATA
Volume 15, Issue 7 , September and October 2018, Pages 67-78
Abstract
In this paper, we use the generalized differentiability concept tostudy the fuzzy transport equation. We consider transport equationin the homogeneous and non-homogeneous cases with fuzzy initialcondition. We also present the solution when speed parameter is a fuzzynumber. Our method is based on the ... Read MoreADMISSIBLE PARTITION FOR BL-GENERAL FUZZY AUTOMATON
Volume 15, Issue 7 , September and October 2018, Pages 79-90
Abstract
In this note, we define the concepts of admissible relation and admissible partition for an arbitrary BL-general fuzzy automaton.In particular, a connection between the admissible partition and the quotient BL-general fuzzy automaton is presented.It is shown that if we use the maximal admissible partition, ...

Volume 15, Issue 7 , September and October 2018, Pages 91-102
Abstract
In this paper, we introduce the notion of co-annihilator of a subsetin a triangle algebra. It is shown that the co-annihilator of asubset is an interval valued residuated lattice (IVRL)-filter. Also, aspecial set of a triangle algebra is defined and the relationshipbetween this set and co-annihilator ...

Volume 15, Issue 7 , September and October 2018, Pages 103-119
Abstract
In this paper, at first we define the concepts of response function and accessible states of a complete residuated lattice-valued (for simplicity we write $\mathcal{L}$-valued) tree automaton with a threshold $c.$ Then, related to these concepts, we prove some lemmas and theorems that are applied in ... Read MoreA TRANSITION FROM TWO-PERSON ZERO-SUM GAMES TO COOPERATIVE GAMES WITH FUZZY PAYOFFS
Volume 15, Issue 7 , September and October 2018, Pages 121-131
Abstract
In this paper, we deal with games with fuzzy payoffs. We proved that players who are playing a zero-sum game with fuzzy payoffs against Nature are able to increase their joint payoff, and hence their individual payoffs by cooperating. It is shown that, a cooperative game with the fuzzy characteristic ... Read MoreON A FUZZY APPLICATION OF THE PARTICULATE MATTERS ESTIMATION
