A cabin crew fatigue risk comprehensive evaluation model

In order to improve the cabin safety of civil aviation and reduce the accident or incident result from cabin crew fatigue, a cabin crew fatigue risk index system is formed through the deep study on the factors affecting cabin crew fatigue and the cabin crew questionnaires from an airline. Based on the order relation analysis method and specialists questionnaires, the weight of each factor is determined. Combination the 1490 cabin crew questionnaires with each self-assessment fatigue result by the cabin crew themselves, the fatigue risk value scope related to every fatigue rating is obtained. Finally, the cabin crew fatigue risk comprehensive evaluation model is established. The results show that this model can be used to evaluate the cabin crew fatigue risk for the airlines, and it is a scientific and objective way to measure and reflect fatigue state.
