The generation of fuzzy sets and the~construction of~characterizing\ functions of~fuzzy data

L. Kovarova; R. Viertl

Volume 12, Issue 6 , November and December 2015, Pages 1-16

Abstract
  Measurement results contain different kinds of uncertainty. Besides systematic errors andrandom errors individual measurement results are also subject to another type of uncertainty,so-called emph{fuzziness}. It turns out that special fuzzy subsets of the set of real numbers $RR$are useful to model fuzziness ...  Read More

Double Fuzzy Implications-Based Restriction Inference Algorithm

Yiming Tang; Xuezhi Yang; Xiaoping Liu; Juan Yang

Volume 12, Issue 6 , November and December 2015, Pages 17-40

Abstract
  The main condition of the differently implicational inferencealgorithm is reconsidered from a contrary direction, which motivatesa new fuzzy inference strategy, called the double fuzzyimplications-based restriction inference algorithm. New restrictioninference principle is proposed, which improves the ...  Read More

Power harmonic aggregation operator with trapezoidal intuitionistic fuzzy numbers for solving MAGDM problems

Satyajit Das; Debashree Guha

Volume 12, Issue 6 , November and December 2015, Pages 41-74

Abstract
  Trapezoidal intuitionistic fuzzy numbers (TrIFNs) express abundant and flexible information in a suitable manner and  are very useful to depict the decision information in the procedure of decision making. In this paper, some new aggregation operators, such as, trapezoidal intuitionistic fuzzy weighted ...  Read More

A Comparative Study of Fuzzy Inner Product Spaces

M. Saheli

Volume 12, Issue 6 , November and December 2015, Pages 75-93

Abstract
  In the present paper, we investigate a connection between two fuzzy inner product one of which arises from Felbin's fuzzy norm and the other is based on Bag and Samanta's fuzzy norm. Also we show that, considering a fuzzy inner product space, how one can construct another kind of fuzzy inner product ...  Read More

Coupled common fixed point theorems for $varphi$-contractions in probabilistic metric\ spaces and applications

S. H. Wang; A. A. N. Abdou; Y. J. Cho

Volume 12, Issue 6 , November and December 2015, Pages 95-108

Abstract
  In this paper, we give some new coupled common  fixed point theorems for probabilistic $varphi$-contractions  in Menger probabilistic metric spaces.  As applications of the main results, we obtain some coupled common fixed point theorems in usual metric spaces and fuzzy metric spaces. ...  Read More

The Urysohn, completely Hausdorff and completely regular axioms in $L$-fuzzy topological spaces

Chengyu Liang; Fu-Gui Shi

Volume 12, Issue 6 , November and December 2015, Pages 109-128

Abstract
  In this paper, the Urysohn, completely Hausdorff and completely regular axioms in $L$-topological spaces are generalized to $L$-fuzzy topological spaces. Each $L$-fuzzy topological space can be regarded to be Urysohn, completely Hausdorff and completely regular tosome degree. Some properties of them ...  Read More

A generalization of the Chen-Wu duality into quantale-valued setting

Chong Shen; Shanshan Zhang; Wei Yao; Changcheng Zhang

Volume 12, Issue 6 , November and December 2015, Pages 129-140

Abstract
  With the unit interval [0,1] as the truth value table, Chen and Wupresented the concept of  possibility computation over dcpos.Indeed, every possibility computation can be considered as a[0,1]-valued Scott open set on a dcpo. The aim of this paper is tostudy Chen-Wu's duality on quantale-valued ...  Read More

Coincidence point theorem in ordered fuzzy metric spaces and its application in integral inclusions

Z. Sadeghi; S. M. Vaezpour

Volume 12, Issue 6 , November and December 2015, Pages 141-154

Abstract
  The purpose of this paper is to present some coincidence point and common  fixed point theorems for multivalued contraction maps in complete fuzzy  metric spaces endowed with a partial order. As an application, we give  an existence theorem of solution for general classes of integral  ...  Read More
