On Modeling A Dynamic Hybrid System with Constraints: Computing Aircraft Landing Trajectories Konstantin Artiouchine Thales TRT, Domaine de Corbeville, 91404 Orsay CEDEX, France and LIX, Ecole Polytechnique, 91128 Palaiseau, France, Philippe Baptiste LIX, Ecole Polytechnique, 91128 Palaiseau, France, Juliette Mattioli Thales TRT, Domaine de Corbeville, 91404 Orsay CEDEX, France, We study the problem of computing trajectories of a set of aircraft in their final descent, right before landing. Trajectories must be compatible with aircraft dynamics while keeping distance between aircraft large enough. Our objective is to determine the order in which aircraft land as well as their exact trajectories in order to minimize the maximal landing time. We study a highly simplified version of this hybrid problem where time and space are discretized. A constraint based model relying on several specific global constraints is introduced. Computational experiments are reported. Key words: Air-Traffic Control, Scheduling, Constraint Programming 1
