Research On Decision Support System Of Airspace Structure Adjustment Based On Major Events

With the sustained rapid growth of China's civil aviation recent years, the contradiction between the air traffic requirement and the limited airspace resource becomes more and more conspicuous. During the periods of major events, the number of flights will increase rapidly, and the flight environment will be more complicated, the current airspace structure will become the bottleneck of the air traffic safety, which will bring heavy load to the air traffic system, so it is the time of great urgency to adjust the airspace structure effectively and reasonably.The definition of major events is stated firstly in the paper, the influence of major events on the civil aviation is analyzed, and the questions that the guarantee of air traffic safety will face during the major events are discussed emphatically. Secondly, in order to increase the airspace capacity and avoid flight conflicts, the structure adjustment strategies of route, sector and terminal are investigated under the basic adjustment principles. Then, from the point view of balancing the workload between sectors, the function of sector structure design with the different sector number based on nonlinear programming is realized, using MATLAB. During the comparison results between the current and designed sectors of Guangzhou terminal airspace, the reasonable of the algorithm is verified. Finally, the decision support system of airspace structure adjustment based on major events is realized on the platform of Delphi.
