In recent years, several different linguistic computational models for dealing with linguistic
information in processes of computing with words have been proposed. However, until now …

The management of hesitant fuzzy information is a topic of special interest in fuzzy decision
making. In this paper, we focus on the use and properties of the fuzzy linguistic modelling …

Uncertain computation is a system of computation and reasoning in which the objects of
computation are not values of variables but restrictions on values of variables. This …

One of the main goals of computing with words is the accurate modeling of natural
language. In this direction, Z-numbers were introduced by Zadeh in 2011 as a pair of fuzzy …

In this paper aggregation functions defined on the set of all discrete fuzzy numbers whose
support is a subset of consecutive natural numbers are introduced and the particular cases …

The aim of this paper is to extend a monotone operation defined on a discrete setting to a
closed binary operation on the partially ordered set A1 of discrete fuzzy numbers whose …

We focus on fuzzy graphs with crisp vertex and fuzzy edge sets. A concept of the fuzzy
chromatic number of these graphs based on fuzzy independent vertex set is used in this …

In a group decision making problem, experts often express their opinions through the so-
called preference relations. In recent years, several different definitions of preference …

In this paper residual implications defined on the set of discrete fuzzy numbers whose
support is a set of consecutive natural numbers are studied. A specific construction of these …

In this article discrete fuzzy numbers are used to model complete and incomplete qualitative
information and some methods to aggregate this kind of information are proposed. When the …
