  • On the complexity of exchanging 

    Molinero Albareda, Xavier; Olsen, Martin; Serna Iglesias, María José (2016-02-04)
    Article

    We analyze the computational complexity of the problem of deciding whether, for a given simple game, there exists the possibility of rearranging the participants in a set of j given losing coalitions into a set of j winning ...
  • Power in voting rules with abstention: an axiomatization of a two components power index 

    Freixas Bosch, Josep; Lucchetti, Roberto (2016-02-09)
    Article
    Restricted access - publisher's policy
    In order to study voting situations when voters can also abstain and the output is binary, i.e., either approval or rejection, a new extended model of voting rule was defined. Accordingly, indices of power, in particular ...
  • Exponential decay in nonsimple thermoelasticity of type III 

    Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2016-01-15)
    Article
    Open Access
    This paper deals with the model proposed for nonsimple materials with heat conduction of type III.We analyze rst the general system of equations, determine the behavior of its solutions with respect to the time and show ...
  • Manipulation in games with multiple levels of output 

    Freixas Bosch, Josep; Parker, Cameron (2015-12)
    Article
    Restricted access - publisher's policy
    In (j,k)-games each player chooses amongst j ordered options and there are k possible outcomes. In this paper, we consider the case where players are assumed to prefer some outcomes to others, and note that when k>2 the ...
  • A method to calculate generalized mixed modified semivalues: application to the Catalan Parliament (legislature 2012-2016) 

    Giménez Pradales, José Miguel; Puente del Campo, María Albina (Springer, 2015-10-01)
    Article
    Restricted access - publisher's policy
    We focus on generalized mixed modified semivalues, a family of coalitional values. They apply to games with a coalition structure by combining a (induced) semivalue in the quotient game, but share within each union the ...
  • Identifying optimal components in a reliability system 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 2008-03)
    Article
    Open Access
    The first step in a reliability optimization process is to make a reliability assessment for each component in the system. If this assessment is made in a qualitative way, by grouping together components with the same ...
  • Multinomial probabilistic values 

    Carreras Escobar, Francisco; Puente del Campo, María Albina (2015-11)
    Article
    Restricted access - publisher's policy
    Multinomial probabilistic values were introduced by one of us in reliability. Here we define them for all cooperative games and illustrate their behavior in practice by means of an application to the analysis of a political ...
  • Forms of representation for simple games: Sizes, conversions and equivalences 

    Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (North Holland Mathematical Library, 2015-07-01)
    Article
    Restricted access - publisher's policy
    Simple games are cooperative games in which the benefit that a coalition may have is always binary, i.e., a coalition may either win or loose. This paper surveys different forms of representation of simple games, and those ...
  • Measuring the relevance of factors in the occurrence of events 

    Fragnelli, Vito; Freixas Bosch, Josep; Pons Vallès, Montserrat; Sanmiquel Pera, Lluís (2014-05-09)
    Article
    Restricted access - publisher's policy
    A new way to compare the relevance of the different factors intervening in the occurrences of an event is presented and developed in this paper. The idea behind the method comes from cooperative game theory but the focus ...
  • Success and decisiveness on proper symmetric games 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (2015-12)
    Article
    Restricted access - publisher's policy
    This paper provides a complete study for the possible rankings of success and decisiveness for individuals in symmetric voting systems, assuming anonymous and independent probability distributions. It is proved that for ...
