Abstract

In order to monitor fatigue risks of air traffic controllers during their duties, with their CFF as an index to evaluate fatigue degree, a relationship equation between fatigue degree and CFF was established based on KSS scale score. Then, fatigue indexes were defined to reflect fatigue state, and a fatigue evaluation method based on CFF value was established. Finally, through a 36-hour simulated control experiment under state of sleep deprivation, CFF and simulated control scores of five subjects were collected, and relationship between the indexes and simulated control scores was analyzed. The results show that the fatigue index of four subjects change periodically, while that of the other one decrease first and then increase all the time. And there is a negative correlation between fatigue index of each subject and their simulated control performance. With the progress of sleep deprivation experiment, the indexes of five subjects present an upward trend, while the simulated performance shows a downward trend. © 2022 China Safety Science Journal.
