Orderings of fuzzy sets based on fuzzy orderings. Part I: the basic approach
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
Article.
Accés obert
Article.
Accés obert
The aim of this paper is to present a general framework for comparing
fuzzy sets with respect to a general class of fuzzy orderings. This approach
includes known techniques based on generalizing the crisp linear ordering ...
On the threshold of bounded pseudo-distances
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
Article.
Accés obert
Article.
Accés obert
This paper deals with the relationship between bounded pseudo-distances
and its associated W'-indistinguishabilities, from which the idea of threshold
of transitivity comes. By the way, bounded pseudo-distances are characterized
Representing upper probability Measures over rational Lukasiewicz logic
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
Article.
Accés obert
Article.
Accés obert
Upper probability measures are measures of uncertainty that generalize
probability measures in order to deal with non-measurable events. Following
an approach that goes back to previous works by H ajek, Esteva, and ...
Exploring a syntactic notion of modal many-valued logics
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
Article.
Accés obert
Article.
Accés obert
We propose a general semantic notion of modal many-valued logic. Then,
we explore the di culties to characterize this notion in a syntactic way and
analyze the existing literature with respect to this framework
Aggregation operators and lipschitzian conditions
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
Article.
Accés obert
Article.
Accés obert
Lipschitzian aggregation operators with respect to the natural T - indistin-
guishability operator Et and their powers, and with respect to the residuation ! T
with respect to a t-norm T and its powers are studied. A ...
