Fuzzy Comprehensive Evaluation on the Risk of Fatigue for Air Traffic Controllers Based on Improved AHP

With the rapid development of civil aviation, flights have increased dramatically. With the increasing flight density, the control interval has been narrowing constantly. Because of the heavy workload of the air traffic controllers (ATCs) in many regions, the risk of severe consequences due to ATCs fatigue becomes increasingly serious. Based on the analysis of the domestic events caused by ATCs fatigue in recent years, this paper investigates the fatigue of ATCs with using the SHEL model—‘L’ subsystem, ‘L-L’ subsystem, ‘L-H’ subsystem, ‘L-E’ subsystem and ‘L-S’ subsystem. It establishes the risk evaluation index system of ATCs fatigue. In the new approach, analytic hierarchy process (AHP) is used to determine the weights of evaluation index for ATCs fatigue. The method of decision making trial and evaluation laboratory (DEMATEL) is applied to revise indexes’ initial weight at all levels and to effectively reduce the influence among evaluation indexes at all levels, so as to enhance objectivity and scientific degree of the indexes’ weight. With the implementing of multilevel fuzzy comprehensive evaluation, each influence on fatigue is collected and corresponding measures are proposed according to the evaluation results to improve the aviation safety.
