DESCRIPTION:Mixed-Integer Non-linear Programming (MINLP) formulations appe
ar to be the natural candidates for aircraft conflict avoidance problems\,
where the need for modeling logical choices suggests the simultaneous pre
sence of discrete as well as continuous variables\, and nonlinear constrai
nts arise from separation condition modeling. We present and discuss mixed
-integer nonlinear optimization models\, one based on velocity-changes sep
aration maneuvers (keeping trajectories unchanged) and another combining t
urn-changes and velocity-changes maneuvers. The models are general enough
to avoid imposing\, as usually done\, separation maneuvers performed simul
taneously by all aircraft\, and are such that for each aircraft the instan
t times to perform maneuvers are decision variables of the problem. The pr
os and cons of the models are discussed.\n\nhttps://indico.math.cnrs.fr/ev
