A problem that we had encountered in the aggregation process, is how to aggregate the
elements that have cardinality> 1. The purpose of this article is to present a new aggregation …

Aggregation operators for linguistic variables usually assume a uniform and symmetrical
distribution of the linguistic terms that define the variable. A well-known aggregation …

Herrera and Martinez initiated a 2-tuple fuzzy linguistic representation model for computing
with words (CW), which offers a computationally feasible method for aggregating linguistic …

In this paper, we provide a new (proportional) 2-tuple fuzzy linguistic representation model
for computing with words (CW), which is based on the concept of" symbolic proportion." This …

The focus of this paper is the linguistic weighted average (LWA), where the weights are
always words modeled as interval type-2 fuzzy sets (IT2 FSs), and the attributes may also …

A summary on the symbolic basic arithmetic operators and aggregation operators of
linguistic information developed by the authors is presented. In particular, label addition …

The need of computing with words has become an important topic in many areas dealing
with vague information. The aim of this paper is to present different tools which support …

Linguistic aggregation operators are a powerful tool to aggregate linguistic information,
which have been studied and applied in a wide variety of areas, including engineering …

The fuzzy linguistic approach has been applied successfully to many problems. However,
there is a limitation of this approach imposed by its information representation model and the …

This article is devoted to defining some aggregation operations between linguistic labels.
First, from some remarks about the meaning of label addition, a formal and general definition …
