  • A mathematical programming approach for different scenarios of bilateral bartering 

    Nasini, Stefano; Castro Pérez, Jordi; Fonseca Casas, Pau (Institut d'Estadística de Catalunya, 2015-01-01)
    Article
    Open Access
    The analysis of markets with indivisible goods and fixed exogenous prices has played an important role in economic models, especially in relation to wage rigidity and unemployment. This paper provides a novel mathematical ...

    This paper discusses a multi-period service scheduling problem. In this problem, a set of customers is given who periodically require service over a finite time horizon. To satisfy the service demands, a set of operators ...
  • Hybrid AC-DC offshore wind power plant topology: optimal design 

    Prada Gil, Mikel de; Igualada González, Lucía; Corchero García, Cristina; Gomis Bellmunt, Oriol; Sumper, Andreas (2015-07-01)
    Article
    Open Access
    The aim of this paper is to present a hybrid AC-DC offshore wind power plant (OWPP) topology and to optimize its design in order to minimize the OWPP's total cost. This hybrid concept is based on clustering wind turbines ...
  • A novel model for arc territory design: promoting Eulerian districts 

    Garcia Ayala, Gariela; González Velarde, José Luis; Rios Mercados, Roger; Fernández Aréizaga, Elena (2015-01-01)
    Article
    Open Access
    The problem of district design for the implementation of arc routing activities is addressed. The aim is to partition a road network into a given number of sectors to facilitate the organization of the operations to be ...
  • On the collaboration uncapacitated arc routing problem 

    Fernández Aréizaga, Elena; Fontana, Dario; Speranza, M. Grazia (2016-03-01)
    Article

    © 2015 Elsevier Ltd. All rights reserved. This paper introduces a new arc routing problem for the optimization of a collaboration scheme among carriers. This yields to the study of a profitable uncapacitated arc routing ...
  • A BRILS metaheuristic for non-smooth flow-shop problems with failure-risk costs 

    Ferrer Biosca, Alberto; Guimarans, Daniel; Ramalhino Lourenço, Helena; Juan Pérez, Ángel Alejandro (2016-02-01)
    Article
    Open Access
    This paper analyzes a realistic variant of the Permutation Flow-Shop Problem (PFSP) by considering a non-smooth objective function that takes into account not only the traditional makespan cost but also failure-risk costs ...
  • Mathematical programming approaches for classes of random network problems 

    Castro Pérez, Jordi; Nasini, Stefano (Elsevier, 2015-09-01)
    Article
    Open Access
    Random simulations from complicated combinatorial sets are often needed in many classes of stochastic problems. This is particularly true in the analysis of complex networks, where researchers are usually interested in ...
