Research On Social Economic Benefit Assessment For Civil Aviation Airspace System

The assessment methods of social economic benefit in the civil aviation airspace system are the main subjects studied in this paper. The social economic benefit of the airspace system in the civil aviation is evaluated by fuzzy mathematics and grey system theory.Firstly, the domestic and overseas research about the social economic benefit of the airspace system is briefly reviewed, and the background and significance of the paper are introduced in allusion to our civil aviation airspace system. Secondly, some basic concepts relating on airspace system and its social economic benefit are expatiated, the leading factors influencing its social economic benefit are confirmed and analyzed. Thirdly, the developmental arm and evaluation body are put forward, the evaluation index system is set up. Subsequently, indexes are analyzed, weighting fixed by AHP method and matter element analysis method, and the social economic benefit of the civil aviation airspace system is evaluated by fuzzy integrated evaluation modeling and grey system comprehensive evaluation modeling. Finally, the results of the two assessment methods are contrasted, based on the results the disadvantages of the present civil aviation airspace system are pointed out, and some suggestions are put forward in order to be corrected and perfect. Though the research, the results of the two assessment methods are consistent, and some theoretical instructions and practical meanings have provided.
