Abstract

Developing pilot workload assessment method is conducive to improving pilot work efficiency and enhancing the reliability of flight operations. In this study, a pilot workload model based on task complexity analysis is built to predict the changing trend of workload under various task scenarios with different task difficulties. Based on multiple resource theory and entropy theory, a pilot workload model is constructed by integrating the analysis of node task complexity and structure task complexity. Further, the Bedford scale and time pressure survey are both adopted to subjectively investigate the workload of 25 flying cadets in the traffic pattern task to verify the model. The correlation coefficients between the theoretical prediction results and the actual measurement results are not less than 0.85, supporting the validity of the model. Besides, compared with the original Bedford workload scale, consideration of time pressure can effectively improve the consistencies between the theoretical prediction results of the model and the actual evaluation results of the flying cadets, indicating the advantage of strengthening the time pressure dimension when using the classic Bedford workload scale to measure the pilot workload. The pilot workload measurement model based on task complexity analysis proposed in this study can provide method support for the optimization designs of flight tasks and pilot training.

基于任务复杂性分析的试点工作量测量模型

制定飞行员工作量评估方法有利于提高飞行员的工作效率，增强飞行运行的可靠性。本研究建立了基于任务复杂度分析的飞行员工作量模型，以预测不同任务难度下各种任务场景下的工作量变化趋势。基于多重资源理论和熵理论，综合分析节点任务复杂度和结构任务复杂度，构建了飞行员工作量模型。此外，还采用贝德福德量表和时间压力调查两种方法，对25名飞行学员在交通模式任务中的工作量进行了主观调查，以验证模型。理论预测结果与实际测量结果的相关系数不小于 0.85，证明了模型的有效性。此外，与原有的贝德福德工作量表相比，考虑时间压力能有效提高模型理论预测结果与飞行学员实际测评结果的一致性，说明在使用经典的贝德福德工作量表测量飞行员工作量时加强时间压力维度的优势。本研究提出的基于任务复杂性分析的飞行员工作量测量模型可为飞行任务和飞行员训练的优化设计提供方法支持。
