Research On The Method Of Airport Terminal Airspace Capacity Dynamic Estimation

In this paper ,an airport terminal airspace capacity dynamic estimation problem was studied systematically and deeply ,which was influenced by the inclement weather gravely on the safety and normal operation of civil aviation. Inclement weather is the main factor to result in flight delay, air traffic capacity uncertainty and serious flight unsafety. Firstly this article has systematically introduced terminal and runway's capacity definition, their capacity evaluation model and various limiting factors, also terminal airspace structure and control procedure was interpreted. Then the Markov model was applied into weather model programming and we used Markov Decision Procedure(MDP) to calculate the weather-avoiding rerouting. Meanwhile the practical route programming limits and the operation on weather information from meteorology department were discussed. This article also has introduced the Terminal Capacity Dynamic Estimation System based on the Markov weather model theory, and the optimizing arithmetic for the aircrafts queue sorting.At last, this paper took the terminal airspace with Hongqiao International Airport and Pudong International Airport for example, evaluated the capacity of the airports and the airspace based on the simulated weather condition. It validated the model's feasibility and correctness.
