RT Book, Section T1 Decision making among alternative routes for UAVs in dynamic environments A1 Ruz Ortiz, José Jaime A1 Arévalo, Orlando A1 Pajares Martínsanz, Gonzalo A1 Cruz García, Jesús Manuel de la AB This paper presents an approach to trajectory generation for Unmanned Aerial Vehicles (UAV)) by using Mixed Integer Linear Programming (MILP) and a modification of the A* algorithm to optimize paths in dynamic environments, particularly having pop-ups with a known future probability of appearance. Each pop-up leads to one or several possible evasion maneuvers, characterised with a set Of values used as decision making parameters in an Integer Linear Programming (ILP) model that optimizes the final route by choosing the Most suitable alternative trajectories, according to the imposed constrains such as maximum fuel consumption and spent time. The model of the system in MILP and A* algorithms is presented as well as the ILP formulation for decision making. Results and discussions are given to promote future real tiem implementations.
