    In the context of aircraft turnaround processes, this paper illustrates how simulation can be used not only to analyze critical activities and paths, but also to generate the associated survival functions –thus providing ...

  • An integration-oriented ontology to govern evolution in big data ecosystems 

    Nadal Francesch, Sergi; Romero Moral, Óscar; Abelló Gamazo, Alberto; Vassiliadis, Panos; Vansummeren, Stijn (CEUR-WS.org, 2017)
    Conference lecture
    Open Access
    Big Data architectures allow to flexibly store and process heterogeneous data, from multiple sources, in its original format. The structure of those data, commonly supplied by means of REST APIs, is continuously evolving, ...

  • Validation of Service Blueprint models by means of formal simulation techniques 

    Estañol Lamarca, Montserrat; Marcos, Esperanza; Oriol Hilari, Xavier; Pérez, Francisco J.; Teniente López, Ernest; Vara, Juan M. (Springer, 2017)
    Conference report
    Open Access
    As service design has gained interest in the last years, so has gained one of its primary tools: the Service Blueprint. In essence, a service blueprint is a graphical tool for the design of business models, specifically ...

    Conference lecture
    Open Access
    The CitScale tool is a software platform for visualizing, analyzing and comparing the impacts of smart city policies based on innovative mobility concepts in urban areas. It places emphasis on new automotive vehicles aimed ...

  • Notes on using simulation-optimization techniques in traffic simulation 

    Ros Oton, Xavier; Montero Mercadé, Lídia; Barceló Bugeda, Jaime (Elsevier, 2017)
    Conference report
    Open Access
    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)
    Conference report
    Open Access
    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

    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)
    Conference report
    Open Access
    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)
    Conference report
    Open Access
    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: ...
