为了测量和评估航天员在轨维修的工作负荷情况，在时间线分析法和资源占用理论的基础上，确定了间接获取的资源需求占用率、直接测量的占用时间两个维度来进行工作负荷主客观综合评估，并提出基于动态时间窗口时间资源占用的工作负荷评估模型。为了验证模型的有效性，搭建典型在轨维修任务——液体回路子系统的维修实验环境，招募受试者，获取主观负荷数据、进行维修视频采集和动素时间测定。结果表明，本文模型的工作负荷值与主观负荷评估值显著相关且吻合较好，验证了模型的有效性。
In order to measure and evaluate the workload of astronauts on-orbit maintenance, based on the time-line analysis and resource utilization theory, we determine the indirect acquisition of resource demand occupancy, direct measurement of occupancy time two dimensions to work load master Objective and comprehensive evaluation, and puts forward a workload evaluation model based on time resource occupation of dynamic time window. In order to verify the validity of the model, a typical in-orbit maintenance task, the maintenance environment of the liquid circuit subsystem, the recruitment of subjects, the acquisition of subjective load data, the maintenance of video acquisition and the determination of moose time were established. The results show that the workload of this model is significantly correlated with the subjective load assessment value and the agreement is good, which verifies the validity of the model.
