Abstract:

The optimum selection of performance based navigation (PBN) flight procedure design scheme is rather important to the enhancement of capacity of terminal area, and to the work quality and efficiency of air traffic management and flight safety. However, in practice, the optimum selection is often made by experts based on their specialized knowledge and experience. This humanmade selection in most cases could be biased or not optimum. To make the optimal selection of PBN flight procedure design schemes more effective and reasonable, this paper proposes an evaluation index system of PBN flight procedure design schemes, and develops a multiattribute decision making model based on relative superiority degree. In this model, the attribute weights and index values of each scheme are interval numbers. The interval numbers are used to compute the relative superiority degree of corresponding scheme. The optimal scheme is determined by finding the greatest relative superiority degree of alternatives. At the end of the paper, an example shows the model applications on selecting the optimal PBN flight procedure scheme. 
