Fatigue-related errors and accidents that occur at work cost the Australian economy $5.8 billion every year. Regulators and employers use mathematical models in special software to assess the fatigue risk associated with work schedules based on prior wake, time of day and recent sleep. Incredibly though, these models assume that the demands of your job have no influence on your level of fatigue, i.e., they do not differentiate between sitting quietly at work – and controlling air traffic, performing surgery or driving a truck. This project will improve the models by assessing how mental task demands affect fatigue. Models that are better able to predict fatigue will improve the health, safety and productivity of the Australian workforce.

工作中发生的与工作相关的错误和事故每年给澳大利亚经济造成58亿澳元的损失。监管机构和雇主使用特殊软件中的数学模型，根据先前的清醒时间、一天中的时间和最近的睡眠时间，评估与工作时间表相关的疲劳风险。令人难以置信的是，这些模型假设你的工作要求对你的疲劳程度没有影响，也就是说，他们不区分安静地坐在工作中--和控制空中交通，做手术或驾驶卡车。本项目将通过评估心理任务需求如何影响疲劳来改进模型。能够更好地预测疲劳的模型将改善澳大利亚劳动力的健康，安全和生产力。
