Understand schedule-related fatigue in your operation

Influenced by sleep history, circadian fluctuation, and time on/off-duty, fatigue has a measurable impact on a worker’s reaction time and ability to perform their job safely


Examine and mitigate fatigue in your operation’s schedules

FAST is based on the SAFTE algorithm developed by the Walter Reed Army Institute of Research at the U.S. Army Medical Research Development Command, used to predict human reaction time, likelihood of lapsed judgement, and fatigue risk. It has been extensively validated as an accurate predictor of fatigue related accident risk by the U.S. Department of Transportation. Learn more about SAFTE.

FAST fatigue modelling software allows researchers and planners to identify areas of fatigue risk in schedule and roster design. It analyzes work schedules, commute times and sleep data to generate minute-by-minute performance predictions.

Benefits

  • Understand the inherent fatigue risk of various schedule designs
  • Assess schedule designs for compliance with fatigue regulations
  • Create targeted programs and schedules that will increase overall employee health, safety and productivity
  • Perform objective post-accident or incident analysis to determine if fatigue may have been a factor.
