A Novel Approach to Automated Merge 4D Arrival Trajectories for Multi-parallel Runways

Abstract : This paper reports on the research status of automated merging 4D trajectories for multi-parallel runways operations in complex terminal area. In order to simultaneously reduce delay and increase capacity in metropolis airport with 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 di erent categories of aircraft with 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 in detail, a modelling strategy with sliding time window and simulated annealing algorithm is proposed for solving this real-time scheduling and sequencing landing problem. According to the relationship between aircraft entry time and the position of sliding time window, all arrival aircraft are firstly classified into 4 di erent status: planned, ongoing, active, and completed, and then in the sliding time window the aircraft with active or ongoing status are optimized with re-sequence and conflict detection and resolution (CD&R) process. Conflict detection (CD) is based on pairwise form to detect separation infringement between aircraft. There are two types of conflict, catching up conflict and converging conflict. Conflict resolution (CR) solve the detected horizontal conflict with speed adjustment, slot time control, and turning time control technique. In a future work, this novel M-PM system will be evaluated with real operational data.
