Further Research On Airport Ground Capacity Evaluation

Airport Ground Capacity Evaluation is essential and a key point to the effective implementation of Airport Flow Management. It plays an important role in reducing flight delays and ensuring flying safety. With former evaluation system as a foundation, the capacity evaluation problem was systematically researched from airport's practical operation point of view. A new scheme to evaluate airport's ground capacity was put forward.First of all, the research productions in this field were introduced; the basic conceptions of theoretical and practical capacity were discriminated; the evaluation model of runway, taxiway and apron was respectively established. Afterwards, combining mathematical model with simulation model, the moving air traffic flow in airport was further analyzed; the algorithms of random flight generation, departure waiting list and taxiing flow optimization was proposed to construct the airport practical evaluation model. According to this model, the capacity evaluation system of Xi'an Xian Yang International Airport was developed by utilizing the programming method of Object Orientation; comparing the results of former evaluation system and that of this one, the correctness of the proposed model was verified; the airport's running status and flight delays were researched through statistics of the system, providing airport ground controllers with reasonable advices. Finally, the further development of airport capacity evaluation was expatiated.
