    S'estudien diverses funcions relacionades amb la presa de decisions en jocs simples. L'anàlisi es restringeix a jocs de decisió simètrics i la seva composició i es dóna per suposat que tots els jugadors comparteixen els ...
  • A note on decisive symmetric games 

    Carreras Escobar, Francisco; Freixas Bosch, Josep; Puente del Campo, María Albina (2011)
    Article
    Restricted access - publisher's policy
    Binary voting systems, usually represented by simple games, constitute a main DSS topic. A crucial feature of such a system is the easiness with which a proposal can be collectively accepted, which is measured by ...
  • A note on first-order projections and games 

    Arratia Quesada, Argimiro Alejandro; Stewart, Iain A. (2003)
    Article
    Open Access
    We show how the fact that there is a first-order projection with successor from the problem TC (transitive clousure) to some other problem Ω enables us to automatically deduce that a natural game problem, LGΩ, whose instances ...
  • A note on multinomial probabilistic values 

    Carreras Escobar, Francisco; Puente del Campo, María Albina (Springer, 2018-04)
    Article
    Open Access
    Multinomial values were previously introduced by one of the authors in reliability and extended later to all cooperative games. Here, we present for this subfamily of probabilistic values three new results, previously ...

    Article
    Restricted access - publisher's policy
    The assignment game introduced by Shapley and Shubik (1972) [6] is a model for a two-sided market where there is an exchange of indivisible goods for money and buyers or sellers demand or supply exactly one unit of the ...
  • A Reply to Mueller (2018) Supply Chain Collaboration: Further Insights into Incentive Alignment in the Beer Game Scenario 

    Ponte, Borja; Fernández, Isabel; Rosillo, Rafael; Parreño, José; García, Nazario (OmniaScience, 2018-09)
    Article
    Open Access
    Purpose: We expand a previous discussion in this journal by proposing a new solution concept, based on game theory, for profit allocation with the aim of aligning incentives in collaborative supply chains. Design/methodo ...
  • A Stackelberg game for modelling asymmetric users' behavior in grid scheduling 

    Kolodziej, Joana; Xhafa Xhafa, Fatos; Bogdanski, Marcin (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Conference report
    Open Access
    In traditional distributed computing the users and owners of the computational resources usually belong to the same administrative domain. Therefore all users are equally entitled to use the resources. The situation is ...
  • A Stackelberg game to derive the limits of energy savings for the allocation of data center resources 

    León Gutiérrez, Xavier; Navarro Moldes, Leandro (Elsevier, 2013-01)
    Article
    Restricted access - publisher's policy
    Energy-related costs are becoming one of the largest contributors to the overall cost of operating a data center, whereas the degree of data center utilization continues to be very low. An energy-aware dynamic provision ...
  • Bounds for the Nakamura number 

    Freixas Bosch, Josep; Kurz, Sascha (Springer, 2019-04)
    Article
    Restricted access - publisher's policy
    The Nakamura number is an appropriate invariant of a simple game to study the existence of social equilibria and the possibility of cycles. For symmetric (quota) games its number can be obtained by an easy formula. For ...
  • Celebrity games 

    Álvarez Faura, M. del Carme; Blesa Aguilera, Maria Josep; Duch Brown, Amalia; Messegué Buisan, Arnau; Serna Iglesias, María José (2016-10-04)
    Article
    Open Access
    We introduce Celebrity games, a new model of network creation games. In this model players have weights (W being the sum of all the player's weights) and there is a critical distance ß as well as a link cost a. The cost ...
  • Celebrity games and critical distance 

    Bofarull Cabello, Antoni (Universitat Politècnica de Catalunya, 2019-07-04)

  • Coalition formation and stability 

    Magaña Nieto, Antonio; Carreras Escobar, Francisco (2018-06)
    Article
    Open Access
    This paper aims to develop, for any cooperative game, a solution notion that enjoys stability and consists of a coalition structure and an associated payoff vector derived from the Shapley value. To this end, two concepts ...
