• A hybrid optimization-simulation approach for robust weekly aircraft routing and retiming 

      Ben Ahmed, Mohamed; Ghroubi, Wisal; Haouari, Mohamed; Sherali, Hanif D. ( Elsevier Ltd , 2017 , Article)
      We address the robust weekly aircraft routing and retiming problem, which requires determining weekly schedules for a heterogeneous fleet that maximizes the aircraft on-time performance, minimizes the total delay, and ...
    • A matheuristic for the robust integrated airline fleet assignment, aircraft routing, and crew pairing problem 

      Ben Ahmed, Mohamed; Hryhoryeva, Maryia; Hvattum, Lars Magnus; Haouari, Mohamed ( Elsevier , 2022 , Article)
      We address an integrated airline scheduling problem that combines three airline planning processes: fleet assignment, aircraft routing, and crew pairing. For a given daily flight schedule, the problem requires simultaneously ...
    • A model and optimization-based heuristic for the operational aircraft maintenance routing problem 

      Al-Thani, Nayla Ahmad; Ben Ahmed, Mohamed; Haouari, Mohamed ( Elsevier Ltd , 2016 , Article)
      This paper investigates the Operational Aircraft Maintenance Routing Problem (OAMRP). Given a set of flights for a specific homogeneous fleet type, this short-term planning problem requires building feasible aircraft routes ...
    • A PSO approach for robust aircraft routing 

      Ben Ahmed, Mohamed; Mansour, Farah Zeghal; Haouari, Mohamed ( IEEE Computer Society , 2016 , Conference Paper)
      To mitigate the impact of unpredictable disruptions, airlines are seeking to proactively design schedules that incorporate some robustness features. In this paper, we propose a novel simulation-optimization approach using ...
    • A simulation-optimization approach for robust aircraft routing 

      Ben Ahmed, Mohamed; Mansour, Farah Zeghal; Haouari, Mohamed ( Universite de Lorraine , 2015 , Conference Paper)
      To mitigate the impact of unpredictable disruptions, airlines are seeking to pro-actively design schedules that incorporate some robustness features. In this paper, we propose a novel simulation-optimization approach using ...
