    • Notes on using simulation-optimization techniques in traffic simulation 

      Ros Oton, Xavier; Montero Mercadé, Lídia; Barceló Bugeda, Jaime (Elsevier, 2017)
      Text en actes de congrés
      Accés obert
      Mathematical and simulation models of systems lay at the core of many decision support systems, and their role becomes more critical when the system is more complex. The decision process usually involves optimizing some ...

    • Practical update management in ontology-based data access 

      Giacomo, Giuseppe De; Lembo, Domenico; Oriol Hilari, Xavier; Savo, Domenico Fabio; Teniente López, Ernest (Springer, 2017)
      Text en actes de congrés
      Accés obert
      Ontology-based Data Access (OBDA) is gaining importance both scientifically and practically. However, little attention has been paid so far to the problem of updating OBDA systems. This is an essential issue if we want to ...

    • A Data-driven approach to improve the process of data-intensive API creation and evolution 

      Abelló Gamazo, Alberto; Ayala Martínez, Claudia Patricia; Farré Tost, Carles; Gómez Seoane, Cristina; Oriol Hilari, Marc; Romero Moral, Óscar (CEUR-WS.org, 2017)
      Text en actes de congrés
      Accés obert
      The market of data-intensive Application Programming Interfaces (APIs) has recently experienced an exponential growth, but the creation and evolution of such APIs is still done ad-hoc, with little automated support and ...

    • Process conformance checking by relaxing data dependencies 

      Estañol Lamarca, Montserrat; Mazuran, Mirjana; Oriol Hilari, Xavier; Tanca, Letizia; Teniente López, Ernest (CEUR-WS.org, 2017)
      Text en actes de congrés
      Accés obert
      Given the events modeled by a business process, it may happen in the presence of alternative execution paths that the data required by a certain event determines somehow what event is executed next. Then, the process can ...

    • OCLuniv: Expressive UML/OCL conceptual schemas for finite reasoning 

      Oriol Hilari, Xavier; Teniente López, Ernest (Springer, 2017)
      Text en actes de congrés
      Accés obert
      Full UML/OCL is so expressive that most reasoning tasks are known to be undecidable in schemas defined with these languages. To tackle this situation, literature has proposed mainly three decidable fragments of UML/OCL: ...

    • The universal ontology: A vision for conceptual modeling and the semantic web 

      Olivé Ramon, Antoni (Springer, 2017)
      Text en actes de congrés
      Accés obert
      This paper puts forward a vision of a universal ontology (UO) aiming at solving, or at least greatly alleviating, the semantic integration problem in the field of conceptual modeling and the understandability problem in ...

    • Integrated approach to network design and frequency setting problem in railway rapid transit systems 

      López Ramos, Francesc; Codina Sancho, Esteve; Marín Gracia, Ángel; Guarnaschelli, Armando (2017-04)
      Article
      Accés obert
      This work presents an optimization-based approach to simultaneously solve the Network Design and the Frequency Setting phases on the context of railway rapid transit networks. The Network Design phase allows expanding ...

    • A branch and bound approach for the capacitated plant location problem using cuts from the partial convex hull 

      Barceló Bugeda, Jaime (1984)
      Report de recerca
      Accés obert
      The efficient solution of capacitated plant location problems usually requires the development of specific software mainly when the problems are pure integer ones, standard mathematical programming codes being highly ...
