执飞任务中剩余脑力负荷量化评估模型

In order to evaluate the mental workload of pilots in flight task, a quantitative evaluation model of mental workload based on task demand load (TDL) and staff workload capacity (SWC) was established. Based on this, the evaluation methods of surplus mental workload (SMWL) and occupancy rate of mwl (ORMWL) were proposed. The information entropy method was used to quantify the amount of information on the information display and control interface, based on the flight situation experiment designed by the MATB task platform, in order to verify the validity of the model, the mental workload of 15 subjects at different task levels was evaluated. Based on the flight situation experiment designed by the MATB task platform, the information entropy method was used to quantify the amount of information on the information display and control interface. In order to verify the validity of the model, the mental workload of 15 subjects at different task levels was evaluated. The results show that the SMWL value of the SMWL model method was correlated with the NASA subjective scale value. And, the increase of task level had a significant U-shaped impact on the mental workload of the staff. Meanwhile, the increase of task level had a significant U-shaped impact on the mental workload of the staff. Therefore, the model established in this paper and based on the concepts of SMWL and ORMWL can be used to conduct a real-time and quantitative evaluation of the mental workload of pilots during flight tasks, providing a new idea for the quantification of mental workload.
