The Operations Reserch group works at the Department of Engineering and Architecture of the University of Trieste. The main activity of the Operations Research group at the University of Trieste is related to mathematical optimisation applied to logistics and transport, with emphasis on various aspects of air traffic management, including market-based mechanisms for ATFM and airport slot allocation, analytical models to integrate flexibility to flights in congested airspaces or subject to disruptions as during explosive volcanic eruptions, and pricing mechanisms to redistribute traffic across the European air network.
