Abstract
International audience; This paper reports on the research status of automated merging 4D trajectories for multi-parallel runwaysoperations in complex terminal area. In order to simultaneously reduce delay and increase capacity in metropolis airportwith multi-parallel runways, based on the classic Point-Merge route structure, a novel Multiple-Points-Merge (M-PM)route system is firstly proposed. It consists of multi-layers on the sequencing legs for dierent categories of aircraftwith H,Mand L, and a M-PM system for Beijing Capital international airport is built with lazy “8” topology. After that,a multiple-objectives function is discussed for this aircraft scheduling problem, operational constraints are analyzed indetail, a modelling strategy with sliding time window and simulated annealing algorithm is proposed for solving thisreal-time scheduling and sequencing landing problem. According to the relationship between aircraft entry time andthe position of sliding time window, all arrival aircraft are firstly classified into 4 dierent status: planned, ongoing,active, and completed, and then in the sliding time window the aircraft with active or ongoing status are optimized withre-sequence and conflict detection and resolution (CD&R) process. Conflict detection (CD) is based on pairwise formto detect separation infringement between aircraft. There are two types of conflict, catching up conflict and convergingconflict. Conflict resolution (CR) solve the detected horizontal conflict with speed adjustment, slot time control, andturning time control technique. In a future work, this novel M-PM system will be evaluated with real operational data.
