Arithmetic Aggregation Operators for Interval-valued Intuitionistic Linguistic Variables and Application to Multi-attribute Group Decision Making
Volume 13, Issue 1 , January and February 2016, Pages 1-23
Abstract
The intuitionistic linguistic set (ILS) is an extension of linguisitc variable. To overcome the drawback of using single real number to represent membership degree and non-membership degree for ILS, the concept of interval-valued intuitionistic linguistic set (IVILS) is introduced through representing ... Read MoreDecision making in medical investigations using new divergence measures for intuitionistic fuzzy sets
Volume 13, Issue 1 , January and February 2016, Pages 25-44
Abstract
In recent times, intuitionistic fuzzy sets introduced by Atanassov has been one of the most powerful and flexible approaches for dealing with complex and uncertain situations of real world. In particular, the concept of divergence between intuitionistic fuzzy sets is important since it has applications ... Read MoreDesigning a model of intuitionistic fuzzy VIKOR in multi-attribute group decision-making problems
Volume 13, Issue 1 , January and February 2016, Pages 45-65
Abstract
Multiple attributes group decision making (MAGDM) is regarded as the process of determining the best feasible solution by a group of experts or decision makers according to the attributes that represent different effects. In assessing the performance of each alternative with respect ... Read MorePiecewise cubic interpolation of fuzzy data based on B-spline basis functions
Volume 13, Issue 1 , January and February 2016, Pages 67-76
Abstract
In this paper fuzzy piecewise cubic interpolation is constructed for fuzzy data based on B-spline basis functions. We add two new additional conditions which guarantee uniqueness of fuzzy B-spline interpolation.Other conditions are imposed on the interpolation data to guarantee that the interpolation ... Read MoreFurther results on $L$-ordered fuzzifying convergence spaces
Volume 13, Issue 1 , January and February 2016, Pages 77-92
Abstract
In this paper, it is shown that the category of $L$-ordered fuzzifying convergence spaces contains the category of pretopological $L$-ordered fuzzifying convergence spaces as a bireflective subcategory and the latter contains the category of topological $L$-ordered fuzzifying convergence spaces ... Read MoreOn The Relationships Between Types of $L$-convergence Spaces
Volume 13, Issue 1 , January and February 2016, Pages 93-103
Abstract
This paper focuses on the relationships between stratified $L$-conver-gence spaces, stratified strong $L$-convergence spaces and stratifiedlevelwise $L$-convergence spaces. It has been known that: (1) astratified $L$-convergence space is precisely a left-continuousstratified levelwise $L$-convergence ... Read MoreCorrespondence between probabilistic norms and fuzzy norms
Volume 13, Issue 1 , January and February 2016, Pages 105-114
Abstract
In this paper, the connection between Menger probabilistic norms and H"{o}hle probabilistic norms is discussed. In addition, the correspondence between probabilistic norms and Wu-Fang fuzzy (semi-) norms is established. It is shown that a probabilistic norm (with triangular norm $min$) can generate a ... Read More$L$-fuzzy approximation spaces and $L$-fuzzy topological spaces
Volume 13, Issue 1 , January and February 2016, Pages 115-129
Abstract
The $L$-fuzzy approximation operator associated with an $L$-fuzzy approximation space $(X,R)$ turns out to be a saturated $L$-fuzzy closure (interior) operator on a set $X$ precisely when the relation $R$ is reflexive and transitive. We investigate the relations between $L$-fuzzy approximation spaces ... Read MoreCommutative pseudo BE-algebras
Volume 13, Issue 1 , January and February 2016, Pages 131-144
Abstract
The aim of this paper is to introduce the notion of commutative pseudo BE-algebras and investigate their properties.We generalize some results proved by A. Walendziak for the case of commutative BE-algebras.We prove that the class of commutative pseudo BE-algebras is equivalent to the class of commutative ...
