| In view of the high busyness of airports with closely spaced parallel runway configurations and the need for appropriate approach strategies,this thesis examines the operation situation under different transfer scenarios to improve the operational efficiency of airfields from the perspective of apron operation and management transfer strategies.Firstly,from the perspective of the layout and operation mode of the closely spaced parallel runway,three types of field structures of domestic and international airports with closely spaced parallel runway are summarised according to the relative positions of runways and terminals.Due to the characteristics of the field structure and the influence of the operation mode,two approach modes that affect the field operation efficiency,namely crossing the runway and using the bypass taxiway,are thus analysed.In order to design the handover points,the apron operation management handover process and handover rules were sorted out,all alternative handover points meeting the conditions were selected,and a handover point design model using conflict avoidance and runway crossing as constraints was established with minimum delay waiting time as the objective.The dynamic handover point selection set is formed through the handover point selection process.Secondly,the dynamic handover point selection set is identified as four handover solutions,and a ground handover operation model that can be determined by crossing the runway or using a go-around slip is established with the minimum ground taxiing time as the objective,and the improved whale optimisation algorithm is used to solve it.The optimal handover strategy is derived for different time periods.Finally,using the SIMMOD simulation software,the thesis builds the model and sets the parameters for the subsystems such as the run-skid system and the station apron system.The results show that the dynamic transfer strategy is more efficient than the traditional transfer model. |
