Abordagem fuzzy para otimização de planos de vôo

Abstract

This thesis is the result of a set of contributions of the development of mathematical algorithms using fuzzy logic aiming to collaborate with the decision making for the air transport segment. Among the problems addressed, the Cost Index applied to the Flight Management Computer installed in modern aircraft with the purpose of optimizing the trajectories was chosen as the central axis for the discussion of strategic formats with a trade-o↵ regime of compliance objectives of planned schedules, minimization of fuel use and criticality assessment in view of the commitment to connect passengers. At the end, an algorithm with the ability to evaluate, along the trajectory, divergences of the estimated arrival time and estimated fuel on board planned through a system of fuzzy rules and the application of corrections in the Cost Index is suggested, dialoguing with the aspects of uncertainty of the trajectory, in order to improve mission performance.
