Research on the Construction and Applicability of Fatigue Management Model for Flight-Line Maintenance Personnel

In order to strengthen the fatigue management ability for flight-line maintenance personnel and ensure the safe operation of civil aviation aircrafts, the paper identifies 19 correlation indexes related to the fatigue of line maintenance personnel by analyzing the questionnaire answers of 829 line maintenance personnel in China. Then the AHP-entropy method is used to determine the weighting system of fatigue indexes for line maintenance personnel. Based on this, a fatigue management model for line maintenance personnel is established with the recognition thresholds set up for different fatigue states. It is found out through verification that, the fatigue management model for line maintenance personnel established in this paper is over 80% accurate in recognizing fatigue, proving to be reliable in fatigue recognition. The study provides decision support for the fatigue management of line maintenance personnel, and enables airlines to develop management software that carries out the whole process fatigue management of line maintenance personnel.
