Research On Optimization Techniques Of Airport Surface Operation

Airport surface operation optimization is one of the most important methods to reduce operationconflicts, taxiing cost and emission within short-term; it has great meaning on both economy andenvironment.This thesis focused on two key resources of surface operation: Apron System and TaxiwaySystem executed scientifically, systematically and deeply research from theory to actual operation.Firstly, research background and meaning, basic concept of airport surface, and relationship betweenoptimization and delay was introduced. Still, research methods and productions within this field homeand abroad was summarized. Then a node-link model of surface network was depicted, based onwhich conflict detection and resolution during runway crossing, taxiing and apron operation wasexpounded. A framework of surface coordinated operation mainly built on apron schedule, taxiingschedule and runway schedule was established, and the way that different parts working coordinatedlywas illustrated. According to this concept, we established two optimized models of gate assignmentand taxi schedule, which aimed at fastening surface operating，reducing delay and improvingefficiency. Gate assignment model was divided into two parts, planning model for tactical stage andadjusting model for real-time, both of the two sub-models can be solved using tabu search algorithm.Taxiing schedule was designed to meet the goal of emission and cost minimization, a rule-basedgenetic algorithm was used to solve the problem. After we get serial optimized data, a3-D airportsurface operation simulation system built on Google Earth platform was designed to simulate andanalyze the results and actual operation data from several aspects, like gate assignment scenario,average taxi time, gate waiting time, delay distribution and airside capacity etc, to validate theoptimization model.
