Modelo para el análisis estático en grafos difusos basado en indicadores compuestos de centralidad
Revista Cubana de Ciencias Informáticas, 2015 Fuzzy graphs have recently grown in popularity for decision support. Finding the most important node in the model has multiple applications. Static analysis in fuzzy graphs is mainly based in only one centrality measure, degree centrality.

OWA Operators in Portfolio Selection
, 2015 Portfolio choice is the process of selecting the optimal proportion of various assets. One of the most well-known methods is the mean-variance approach developed by Harry Markowitz. This paper introduces the ordered weighted average (OWA) in the mean-variance model.

Induced aggregation operators in decision making with the Dempster-Shafer belief structure [PDF]
We study the induced aggregation operators. The analysis begins with a revision of some basic concepts such as the induced ordered weighted averaging (IOWA) operator and the induced ordered weighted geometric (IOWG) operator.

Modelling fraud detection by attack trees and Choquet integral [PDF]
Modelling an attack tree is basically a matter of associating a logical ÒndÓand a logical ÒrÓ but in most of real world applications related to fraud management the Ònd/orÓlogic is not adequate to effectively represent the relationship between a parent ...

WORD SENSE DISAMBIGUATION METHOD USING SEMANTIC SIMILARITY MEASURES AND OWA OPERATOR [PDF]
ICTACT Journal on Soft Computing, 2015 Query expansion (QE) is the process of reformulating a query to improve retrieval performance. Most of the times user's query contains ambiguous terms which adds relevant as well as irrelevant terms to the query after applying current query expansion ...

OWA-based fuzzy m-ary adjacency relations in Social Network Analysis. [PDF]
In this paper we propose an approach to Social Network Analysis (SNA) based on fuzzy m-ary adjacency relations. In particular, we show that the dimension of the analysis can naturally be increased and interesting results can be derived.
