Popis: Decision support capabilities that provide flight-specific reroutes around constraints can enable more flexible and agile management of the airspace. For this benefit to be realized, automation must reliably provide operationally acceptable alternatives to traffic managers. This Paper proposes an approach for generating a small number of diverse, feasible solutions for further evaluation by traffic managers. Using a variation on Dijkstra’s shortest-path algorithm, reroutes are designed for one or more flights, in which multiflight problems promote the active design of reroute flows. A multi-objective genetic algorithm is employed to evaluate tradeoffs between multiple criteria of operational acceptability, removing the need to predefine relative metric weightings. Finally, a combination of principal components analysis and spectral clustering is used to identify distinct groups of solutions and representative reroutes that capture different tradeoffs between metrics of operational acceptability.
