Mathematical aspects of the theory of measures of fuzziness
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Accés obertAfter recalling the axiomatic concept of fuzziness measure, we define some fuzziness measures through Sugeno’s and Choquet’s integral. In particular, for the so-called “homogeneous” fuzziness measures we prove two ... -
Método numérico para la evaluación holística del riesgo sísmico utilizando la teoría de conjuntos difusos
(Universitat Politècnica de Catalunya. CIMNE, 2014)
Article
Accés obertLa teoría de conjuntos difusos ofrece un puente entre el procesamiento simbólico y el numérico que permite el uso de conceptos cualitativos útiles en el proceso de toma de decisiones relacionadas con la gestión del riesgo ... -
Mining and visualizing uncertain data objects and named data networking traffics by fuzzy self-organizing map
(CEUR-WS.org, 2014)
Text en actes de congrés
Accés obertUncertainty is widely spread in real-world data. Uncertain data-in computer science-is typically found in the area of sensor networks where the sensors sense the environment with certain error. Mining and visualizing ... -
On the relationship between T-transitivity and approximate equality
(2003-01)
Article
Accés restringit per política de l'editorialThe paper discusses the suitability of T-transitivity for modelling approximate equality. It explains how T-transitivity, a property suitable for modelling vagueness, can still be used to handle the imprecision inherent ... -
Ovchinnikov's automorphisms revisited
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1994)
Article
Accés obertIn [6] an approach to the representation of synonyms and antonyms via the automorphisms of the De Morgan Algebra [0,1] x was suggested. In [3], Ovchinnikov established a representation theorem for automorphisms of the ... -
Profit allocation in fuzzy cooperative games in manufacturing and logistics industry
(OmniaScience, 2014-05)
Article
Accés obertPurpose: Alliance between manufacturing and logistics industry is a new model of the joint development of the two industries. A reasonable profit allocation mechanism is the key to ensure the stable operation of the alliance, ... -
Similarity in fuzzy reasoning
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
Article
Accés obertFuzzy set theory is based on a `fuzzification' of the predicate in (element of), the concept of membership degrees is considered as fundamental. In this paper we elucidate the connection between indistinguishability modelled ... -
Social aggravation estimation to seismic hazard using classical fuzzy methods
(Springer, 2015)
Capítol de llibre
Accés obertIn the last years, from a disasters perspective, risk has been dimensioned to allow a better management. However, this conceptualization turns out to be limited or constrained, by the generalized use of a fragmented risk ... -
Testing satistical hipotheses in fuzzy environment
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1997)
Article
Accés obertIn traditional statistics all parameters of the mathematical model and possible observations should be well defined. Sometimes such assumption appears too rigid for the real-life problems, especially while dealing ... -
The logistic decision making in management accounting with genetic algoritms and fuzzy sets
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2000)
Article
Accés obertThe logistics problems in business environments deal with assignation from a number of sources to a number of destinations. Each source offers amounts of goods, while each destination demands quantities of these goods. The ... -
Transitive closure and betweenness relations
(2001-06)
Article
Accés restringit per política de l'editorialIndistinguishability operators fuzzify the concept of equivalence relation and have been proved a useful tool in theoretical studies as well as in di0erent applications such as fuzzy control or approximate reasoning. One ... -
Vagueness and its representations: a unifying look
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1998)
Article
Accés obertUsing the notion of a vaguely defined object, we systematize and unify different existing approaches to vagueness and its mathematical representations, including fuzzy sets and derived concepts. Moreover, a new, approximative ... -
Wrapper-based fuzzy inductive reasoning model identification for imbalance data classification
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Comunicació de congrés
Accés obertFuzzy Inductive Reasoning (FIR) is a qualitative inductive modeling and simulation methodology for dealing with complex dynamical systems. FIR has proven to be a powerful tool for qualitative model identification and ...
