Abstract: The question of optimization for aircraft taxiing time is proposed to minimize the time spent in taxiing system, which can also improve the resource utilization and get good financial benefits by optimizing and distributing the resource.The airport system function composition is systematically illustrated.The airport ground system can be regarded as an airport network topology with nodes and arcs.The basic rules of the aircraft taxiing are presented and three kinds of possible taxi conflicts are discussed.The core of this study are the optimization model with the constraints of the safety separation, taxing rules and conflictfreeand an optimizing algorithm of airplane taxiway for arrival and departure flights.Taken Tianjin Binhai international airport as an example, the optimum result and the actual taxiing time are compared based on the field data, which shows the feasibility and the advantage of the model.
