Multi-aircraft Rerouting Method Under Dangerous Weather

Abstract

In view of the problems that single-aircraft rerouting method existing in civil aviation considered little about the associated effects of multi-aircraft and route network characteristics. A multi-aircraft rerouting method under dangerous weather was proposed. Based on the characteristics of network failures during the occurrence of dangerous weather, the performance indicators and related constraints of temporary routes are analyzed to establish a singleaircraft rerouting model. Then, a multi-aircraft rerouting model based on layout of diversion points was proposed in combination with the performance indicators of the rerouted route network, and solved by NSGA-III algorithm. Finally, a simulation analysis was conducted using the regional flight route network in part of the Beijing Flight Information District as an example and the results show that multi-aircraft rerouting method can effectively avoid flight conflicts and improve the comprehensive characteristics of the network.
