  • Modelling decision support systems using conceptual constraints: linking process systems engineering and decision making models 

    Dombayci, Canan; Espuña Camarasa, Antonio (2017)
    Text en actes de congrés
    Accés obert
    This paper presents the use of a Conceptual Constraint (CC) Domain to systematize the construction of Decision Making Models (DMMs). The modelling systematics include the integration between the CC Domain and production ...

  • Multiparametric metamodels for model predictive control of chemical processes 

    Shokry, Ahmed; Dombayci, Canan; Espuña Camarasa, Antonio (Elsevier, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This work proposes a Data-Based MultiParametric-Model Predictive Control (DBMPMPC) methodology, which enables simple implementations of explicit MPC in situations when the deep mathematical knowledge required to develop ...

  • An optimization model for the long-term planning of energy distribution networks 

    Somoza Tornos, Ana; Pozo Fernández, Carlos; Hoz Casas, Jordi de la; Guillén Gosálbez, Gonzalo; Espuña Camarasa, Antonio; Graells Sobré, Moisès (2016)
    Comunicació de congrés
    Accés obert
    Although design is a problem that has been addressed in the literature, maintaining, upgrading and expanding energy distribution networks along the entire life-cycle is a topic that has received scarce attention. The problem ...

  • Incremental learning fault detection algorithm based on hyperplane-distance 

    Ardakani, Mohammadhamed; Escudero Bakx, Gerard; Graells Sobré, Moisès; Espuña Camarasa, Antonio (Elsevier, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Traditional methods for Fault Detection and Diagnosis (FDD) usually, consider that processes operate under a single steady condition, but because of several reasons (e.g.: equipment aging), operation conditions of ...

  • Kriging based fault detection and diagnosis approach for nonlinear noisy dynamic processes 

    Shokry, Ahmed; Ardakani, Mohammadhamed; Escudero Bakx, Gerard; Graells Sobré, Moisès; Espuña Camarasa, Antonio (Elsevier, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a hybrid approach to enhance the performance of the data-based Pattern Classification Techniques (PCTs) used for Fault Detection and Diagnosis (FDD) of nonlinear dynamic noisy processes. The method ...

  • Optimal features selection for designing a fault diagnosis system 

    Ardakani, Mohammadhamed; Askarian, Mahdieh; Shokry, Ahmed; Escudero Bakx, Gerard; Graells Sobré, Moisès; Espuña Camarasa, Antonio (Elsevier, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Fault diagnosis (FD) using data-driven methods is essential for monitoring complex process systems, but its performance is severely affected by the quality of the used information. Additionally, processing huge amounts of ...

  • A general MILP model for the sizing of islanded/grid-connected microgrids 

    Alabert Aldana, Aniol; Somoza Tornos, Ana; Hoz Casas, Jordi de la; Graells Sobré, Moisès (2016)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    Recently, energy systems have experienced a change of paradigm, from a large-scale centr alized approach to the in-situ exploitation of renewabl e sources. Special atte ntion has been paid to microgrids, a particular case ...

  • On the process of building a process systems engineering ontology using a semi-automatic construction approach 

    Dombayci, Canan; Farreres de la Morena, Xavier; Rodríguez Hontoria, Horacio; Muñoz Mata, Edrisi; Capon Garcia, Elisabeth; Espuña Camarasa, Antonio; Graells Sobré, Moisès (Elsevier, 2015)
    Comunicació de congrés

  • Negotiations provider-client for supply chains coordination under competitiveness 

    Hjaila, Kefah; Puigjaner Corbella, Lluís; Espuña Camarasa, Antonio (2015)
    Comunicació de congrés
    Accés obert
    Current tactical models of Supply Chain s (SC ) associate the conflicts among independent SCs with the uncertain behavio u r of external echelons (third parties). Although the trend now arises to solve these conflicts using ...

  • A meta-multiparametric framework: Application to the operation of bio-based energy supply chains 

    Medina González, Sergio Armando; Shokry Abdel-aleem, Ahmed; Silvente Saiz, Javier; Espuña Camarasa, Antonio (Elsevier, 2015)
    Text en actes de congrés
