Analysis of human error influence factors and evaluation indexes weights determination for air traffic controller
Dong Bao-jian · Journal of Safety Science and Technology · 2011
Based on the SHELL model,the influence factors of air traffic controller were analyzed from internal factors and external factors according to the principle of Ergonomics.Internal factors included three parts: physiological factors,psychological factors,operational skills,and external factors also included three parts: air traffic controller and the team of air traffic controller,the equipment of air traffic control,the manual and etc.of air traffic control.The indexes system of human error influence factors for air traffic controller was constructed according to investigation on the expert of air traffic management, and a triangular fuzzy complementary judgment matrix was constructed with the experts' judgment information expressed by triangular fuzzy numbers 0.1-0.9.Through comparison and analysis,the general importance of each factor was obtained and ranked,the top eight of three level indexes sequence were: working under influence of alcohol after drink,situation awareness,personality collocation of the team of air traffic controller,ability of the team of air traffic controller,fatigue,man-machine interface,external pressure,emotional state.It provides basis for the air traffic controller training and safety check for the traffic management.
