Optimization of Departure Trajectory for Noise Abatement of Sensitive Locations

Adopting the noise abatement procedures(NAPs) is the common approach for abating the noise around airport for the international civil aviation. But there is only one or two procedures used in China. This paper first gives a preliminary model of optimizing the departure trajectory, which is one of the most important in the NAPs. Then it proposes two approaches with two algorithms respectively, the ant colony algorithm and the relaxed lexicographic algorithm, to solve the problem. The two approaches will be compared in the nature of themselves, and the simulation results will verify the feasibility of the both algorithms. It provides the foundation for the next further study.
