摘要: 为了测量和评估航天员在轨维修的工作负荷,在时间线分析法和多资源占用理论的基础上,确定了用间接获取的资源需求占用率、直接测量的占用时间2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的时间-多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试验环境,招募被试,获取主观工作负荷数据,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工作负荷评估值显著相关且吻合较好,验证了其有效性。

Abstract: To measure and evaluate the astronauts' workload of on-orbit maintenance, based on timeline analysis and multi-resource theory, the subjective and objective comprehensive evaluation of the workload was carried out by using two dimensions of "indirect acquisition value of the resource demand occupancy rate" and "direct measurement value of the occupied time". A workload evaluation model based on dynamic time scene and time resource occupancy was put forward. In order to verify the effectiveness of the proposed model, the maintenance experiment of the liquid circuit subsystem, as a typical on-orbit maintenance task, was established. Testees were recruited to obtain the subjective workload questionnaires, maintenance videos were acquired, and the occupation time of therbligs was measured. The results reveal that the workload values of the proposed model have good agreement and significant correlation with subjective workload evaluation values. Hence the effectiveness of the workload evaluation model is validated.

Key words: on-orbit maintenance, multi-resource theory, timeline analysis, workload, evaluation model
