    Faura Gatius, Oriol (Universitat Politècnica de Catalunya, 2016-09-05)
    Master thesis
    Open Access
    El siguiente Trabajo de Fin de Máster consiste en resolver el problema de programación flexible Job-Shop donde el índice de eficiencia a minimizar está formado por la suma de los costes de la energía eléctrica necesaria ...
  • Increasing the Efficiency and Productivity in the Production of Low Voltage Switchboard Using Resource Constrained Project Scheduling 

    Tannady, Hendy; Maimury, Yona (OmniaScience, 2018-03)
    Article
    Open Access
    Purpose: This research was made with the aim to give a scheduling proposal for the assembly activity and the proposal to allocate those activities into available resources using the resource-constrained project scheduling. ...
  • Mixed integer linear programming models for Flow Shop Scheduling with a demand plan of job types 

    Bautista Valhondo, Joaquín; Alfaro Pozo, Rocío (2018-05-29)
    Article
    Open Access
    This paper presents two mixed integer linear programming (MILP) models that extend two basic Flow Shop Scheduling problems: Fm/prmu/Cmax and Fm/block/Cmax. This extension incorporates the concept of an overall demand plan ...
  • Optimal batch scheduling of a multiproduct dairy process using a combined optimization/constraint programming approach 

    Escobet Canal, Teresa; Puig Cayuela, Vicenç; Quevedo Casín, Joseba Jokin; Palà Schönwälder, Pere; Romera Formiguera, Juli; Adelman, Winfried (Pergamon Press, 2019-03-08)
    Article

    This paper presents the optimal batch scheduling of a multi-product dairy process using an approach that combines optimization and constraint programming techniques. A suitable model describing the subprocesses and production ...
  • Real-time services in EPON 

    Garfias Hernandez, Paola; Sallent Ribes, Sebastián; Gutiérrez González, Lluís; Camps Mur, Daniel (2012)
    Conference lecture
    Restricted access - publisher's policy
    This paper proposes an improved scheduling algorithm that optimizes the allocation of the real-time services and elastic flows in EPON by spreading the real-time service periods lowering the delay and thus fulfilling the ...
