本文中讨论的实验解决了在多任务环境中部分任务自动化对操作员性能、工作负荷和疲劳的影响。整个任务环境包括跟踪、资源管理和多个监视子任务。当跟踪子任务自动化时，观察到更慢、更准确的监测和更好的资源管理。虽然据报告，自动跟踪时工作量较低，但在手动和自动跟踪期间，疲劳程度同样增加。当参与者可以通过手动和自动跟踪之间切换来控制工作量时，7小时培训的参与者在自动和手动跟踪之间切换。它们在可选自动化期间的性能上级它们在仅手动控制或仅自动控制可用的条件下的性能。研究结果支持对自动化系统进行自由裁量控制的实用性。
The experiments discussed in this article addressed the influence of part-task automation on operator performance, workload, and fatigue in a multitask environment. The overall task environment included tracking, resource management, and multiple monitoring subtasks. Slower, more accurate monitoring and better resource management were observed when the tracking subtask was automated. Although lower workload was reported when tracking was automated, fatigue increased equally during periods of manual and automatic tracking. When participants could control workload by shifting between manual and automatic tracking, participants with 7 hr of training switched between automatic and manual tracking. Their performance during optional automation periods was superior to their performance in conditions in which only manual control or only automated control was available. The findings argue for the utility of discretionary control of automated systems.
