The PhD defence will be partially digital, in room 720, Niels Henrik Abels hus and streamed directly using Zoom. The host of the session will moderate the technicalities while the chair of the defence will moderate the disputation.

Ex auditorio questions: the chair of the defence will invite the audience to ask questions ex auditorio at the end of the defence. If you would like to ask a question, click 'Raise hand' and wait to be unmuted.

Trial lecture

8th of June, time: 1:15 pm, room 720 and Zoom.  

"Collaborative decision making in air traffic management: applications, current trends and research advances"
  • Join the trial lecture
    The webinar opens for participation just before the trial lecture starts, participants who join early will be put in a waiting room. 

Main research findings 

Traffic volumes are increasing in most of the major modes of transportation. As population centers grow in size and density, the increasing demand for public transit and delivery services leads to increased rail and road traffic. At the same time, it can be hard to expand the available infrastructure, as space is often at a premium where the population growth is fastest. Traffic management problems are a class of optimization problems where we seek to minimize delay or maximize throughput when using scarce infrastructure resources.

In this thesis, I develop Integer Programming approaches suitable for practical, real-time application in air and rail traffic management. To achieve the needed efficiency, I introduce new modelling ideas and algorithmic developments. I make use of decomposition and iterative solution approaches. The results of this work include a working algorithm for optimal dispatching at Oslo Central Station.
