• An Adaptive Iterated Local Search for the Mixed Capacitated General Routing Problem 

      Dell'Amico, Mauro; Diaz Diaz, Jose Carlos; Hasle, Geir; Iori, Manuel (Journal article; Peer reviewed, 2016)
      We study the mixed capacitated general routing problem (MCGRP) in which a fleet of capacitated vehicles has to serve a set of requests by traversing a mixed weighted graph. The requests may be located on nodes, edges, and ...
    • An Estimator for Traffic Breakdown Probability Based on Classification of Transitional Breakdown Events 

      Arnesen, Petter; Hjelkrem, Odd Andre (Journal article; Peer reviewed, 2017)
      In this paper we propose a new estimator for calculating the probability of traffic breakdown as a function of traffic demand. Traffic breakdown is a well-studied phenomena within previous literature and is of great ...
    • Integrating Timetabling and Crew Scheduling at a Freight Railway Operator 

      Bach, Lukas; Dollevoet, Twan; Huisman, Dennis (Journal article; Peer reviewed, 2016)
      We investigate to what degree we can integrate a Train Timetabling / Engine Scheduling Problem with a Crew Scheduling Problem. In the Timetabling / Engine Scheduling Problem we determine for each demand a specific time ...
    • Time-indexed formulations for the Runway Scheduling Problem 

      Avella, Pasquale; Boccia, Maurizio; Mannino, Carlo; Vasiliev, Igor (Journal article; Peer reviewed, 2017)
      Abstract The problem of sequencing and scheduling airplanes landing and taking off on a runway is a major challenge for air traffic management. This difficult real-time task is still carried out by human controllers, with ...
