The subject matter of the article is the processes of the activity of air controllers on duty shift of the area control center (ACC) of the air traffic services system. The goal is the development of a method for assessing the activity of the ACC shift on air traffic services. The tasks to substantiate the possibility of using the automated control system of the air traffic controller in the air traffic control. The methods used are: methods of fuzzy logic, methods of mathematical statistics, methods of expert evaluations. The following results were obtained: A methodology for obtaining personal ratings by persons on duty shifts with ACCs is suggested. A method for assessing the activity of the on-duty shift of ACCs is developed, taking into account the organization of interaction between air traffic controllers and the head of flights for air traffic services. Conclusions. For automated control over the activity of the duty shift of the ACC and the development of recommendations for improving the quality of air traffic services, it was suggested to apply the method of assessing the activity of the duty shift of the ACC, based on the application of the models of the air traffic controller.
