Evaluation of air traffic management system using a hybrid model

Abstract

Priority analysis of critical factors and comprehensive evaluation of different development alternatives are very important for construction and improvement of national air traffic management system (ATMS). This paper presents a hybrid model that decomposes the evaluation problem into two levels. In the upper-level, an analytic network process (ANP) is given to evaluate the importance values of critical factors in ATMS. In the low level, the utility values of alternatives under each factor are estimated by the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS). In order to derive global scores of ATMS alternatives, a simplified synthesis process is provided. Finally, a numerical example is given for illustration.
