PLANNING OF TRAINING AIRCRAFT FLIGHT HOURS

open access: yesCroatian Operational Research Review, 2010
Maintenance of the training aircraft causes downtime of operations and thereby reduces the operational availability, which is crucial for flight planning in a training organisation.

A Discrete-Continuous Algorithm for Free Flight Planning

open access: yesAlgorithms, 2020
We propose a hybrid discrete-continuous algorithm for flight planning in free flight airspaces. In a first step, our discrete-continuous optimization for enhanced resolution (DisCOptER) method computes a globally optimal approximate flight path on a ...
