Research on Runway Incursion Risk Assessment Based on Improved Analytic Network Process

Runway incursions have become an important factor that threaten the safe operation of aviation. Based on the thoughts of system engineering, main factors causing runway incursion incidents and their associated relationships are analyzed and a runway incursion risk assessment index system is established from three aspects of airports, air traffic control, and airlines; The traditional analytic network process is improved by triangular fuzzy numbers, and a research model for runway incursion risk assessment is established based on this; Through the analysis of examples, the main factors affecting the runway incursion risk are obtained. The results show that the method is feasible and effective, which can reflect the relationship between risk factors and reduce the influence of subjective judgment on the index weight, and help develop effective measures to prevent runway incursions. The workload of controller, lost situation awareness and deviation operation/negligence of pilot are main risk factors during the production of runway incursion.
