Integrated Model for Workload Assessment Based on Multiple Physiological Parameters Measurement
Aviation safety has been the focus of attention since the birth of the first plane. As the safety of aircrafts itself has been greatly improved, aviation human factors have now become the main cause of aviation accidents. This paper mainly aims at building a workload comprehensive evaluation model with effective features deriving from the physiological parameters of the pilots. In order to extract the specific features related to the pilot’s workload, each physiological parameter collected in our experiment was tested for its validity and reliability separately. Finally, four main variables related to pilot’s workload were derived from the features screened as the pilot workload assessment comprehensive variables with the principal component analysis (PCA) and the absolute value of the four main variables all decrease when the workload of pilots increases.
