Metaheuristic Approach to Probabilistic Aircraft Conflict Detection and Resolution Considering Ensemble Prediction Systems
Description
This paper presents a methodology to tackle the
problem of strategic aircraft conflict detection and resolution, up
to 60 minutes in advance, considering wind and temperature
uncertainties. The problem of hundreds of en-route aircraft
flying multi-segmented 2D trajectories is considered. The weather
uncertainty is retrieved from Ensemble Prediction Systems. The
conflict detection is based on ensemble trajectory prediction,
and is performed using an efficient grid-based procedure. A
metaheuristic approach is developed to solve the conflicts, based
on simulated annealing, which generates resolution trajectories
by modifying the location of the route waypoints (vectoring),
with the aim of lowering the probabilities of the conflicts while
also minimising the deviation from the nominal paths. Realistic
applications in scenarios with different traffic densities are
presented.
