    • Solutions to the facility location problem with general Bernoulli demands 

      Albareda Sambola, Maria; Fernández Aréizaga, Elena; Saldanha da Gama, Francisco (2015)
      Conference report
      Open Access
      In this work we address the facility location problem with general Bernoulli demands. Extended formulations are proposed for two different outsourcing policies, which allow using sample average approximation for estimating ...
    • Train-scheduling optimization model for railway networks with multiplatform stations 

      Garrisi, Gianmarco; Cervelló Pastor, Cristina (2019-12-28)
      Open Access
      This paper focuses on optimizing the schedule of trains on railway networks composed of busy complex stations. A mathematical formulation of this problem is provided as a Mixed Integer Linear Program (MILP). However, the ...
    • Tuning of operators in memetic algorithms for independent batch scheduling in computational grids 

      Xhafa Xhafa, Fatos; Duran, B.; Barolli, Leonard; Kolici, Vladi; Miho, Rozeta; Takizawa, Makoto (2012)
      Conference report
      Restricted access - publisher's policy
      Efficient scheduling of jobs to resources is a core service of Computational Grids (CGs). Due to the large scale, the dynamic nature and the highly heterogeneous tasks and resources, scheduling is a challenging problem in ...
