  • Ability to separate situations with a priori coalition structures by means of symmetric solutions 

    Giménez Pradales, José Miguel (2017)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    We say that two situations described by cooperative games are inseparable by a family of solutions, when they obtain the same allocation by all solution concept of this family. The situation of separability by a family of ...
  • A new procedure to calculate the Owen value 

    Puente del Campo, María Albina; Giménez Pradales, José Miguel (2017)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    In this paper we focus on games with a coalition structure. Particularly, we deal with the Owen value, the coalitional value of the Shapley value, and we provide a computational procedure to calculate this coalitional value ...
  • On the construction of high dimensional simple games 

    Olsen, Martin; Kurz, Sascha; Molinero Albareda, Xavier (IOS Press, 2016)
    Text en actes de congrés
    Accés obert
    Voting is a commonly applied method for the aggregation of the preferences of multiple agents into a joint decision. If preferences are binary, i.e., “yes” and “no”, every voting system can be described by a (monotone) ...
  • Components with higher and lower risk in a reliability system 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (Fundación Mapfre, 2015)
    Text en actes de congrés
    Accés obert
    A new reliability importance measure for components in a system, that we call Representativeness measure, is introduced. It evaluates to which extent the performance of a component is representative of the erformance of ...
  • Computational procedure for a wide family of mixed coalitional values 

    Giménez Pradales, José Miguel; Puente del Campo, María Albina (2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We consider a family of mixed 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 payoff so obtained by applying ...
  • Similarities and differences between success and decisiveness 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (AA Publications, 2014)
    Text en actes de congrés
    Accés obert
    We consider binary voting systems in which a probability distribution over coalitions is known. In this broader context decisiveness is an extension of the Penrose-Banzhaf index and success an extension of the Rae index ...
  • The representativeness reliability importance measure 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A new reliability importance measure for components in a system, that we call Representativeness measure, is introduced. It evaluates to which extent the performance of a component is representative of the performance ...
  • Cooperation tendencies and evaluation of games 

    Carreras Escobar, Francisco; Puente del Campo, María Albina (SciTePress, 2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Multinomial probabilistic values were first introduced by one of us in reliability and later on by the other, independently, as power indices. Here we study them on cooperative games from several viewpoints, and especially as ...
  • Nodes of directed graphs ranked by solutions defined on cooperative games 

    Amer Ramon, Rafael; Giménez Pradales, José Miguel; Magaña Nieto, Antonio (2010)
    Comunicació de congrés
    Accés obert
    Hierarchical structures, transportation systems, communication networks and even sports competitions can be modeled by means of directed graphs. Since digraphs without a predefined game are considered, the main part of ...
  • Consorcios y valor de Shapley 

    Llongueras Arola, Maria Dolors; Magaña Nieto, Antonio (2010)
    Text en actes de congrés
    Accés obert
    La coordindación de estrategias en un juego cooperativo, cuando un grupo de jugadores decide actuar en conjunto es la base de la noción de consorcio. Un consorcio en un juego cooperativo es una coalición que posee una ...
