Research On The Dispatch Release Of The Special Plateau Airports Based On Decision Support Theory

China is the country possessing the world's largest number of special plateau airports which are mostly located in China's western region. Along with the implementation of the western development strategy and the rapidly increase of the domestic market demanding, more and more airlines engage in the airline operations of the western special plateau airports. However, these special plateau airports are mostly situated in mountainous area with complex terrain environment and atrocious weather conditions, which has brought a lot of difficulties to the airlines dispatch.From the point of dispatch release, combing with the operation characteristics and special requirements of special plateau airports, a dispatch release index system was established, and a method of dispatch decision Support for the special plateau airport was proposed by using decision support theory. First, this paper summarizes the operation environment of special plateau airports characteristics from three aspects: the meteorological environment, terrain environment, approach and departure environment. In addition, the paper gives the assessment item of dispatch release a detailed analysis. Then, hierarchical system model was established by combining the characteristics of the special plateau airport operation environment with the capability requirements of dispatchers. The capacity requirements of dispatchers were researched. On this basis, with the operation specific requirements of special plateau airport operating and the operation statistics, the important factors affecting the special plateau airport route dispatch were determined by the experts investigation. Finally, based on the decision support theory, using the knowledge of fuzzy decision-making and hierarchical analysis, comprehensive evaluation model was established, and the complete data was analyzed with MATLAB processing. Eventually the probability of flight landing was worked out for the purpose of assisting dispatchers release the flight to the special plateau airport, and the model reference and theoretical in this paper will be support for the development of dispatch release decision support system.
