Quantifying Schedule Fatigue
Quantification of fatigue in your schedule
Clockwork utilises bio-mathematical models to analyse both planned and worked schedules to provide you with the answers to key questions:
- What features of our planned and actual schedules are consistently contributing to elevated fatigue levels?
- What is the impact of on-the-day delays or operational changes on fatigue?
- How do fatigue levels change per month and seasonally?
- Do our different bases have different fatigue profiles
- Are we continually improving?
Assessing the impact of schedule changes
One way in which bio-mathematical models can enhance FRM is by assessing the impact that changes to schedules or alternative schedule designs have on fatigue. For example, fatigue models can help to answer the following questions:
- For my long-haul or ULR operation, how can we schedule crew in the days or weeks prior to the flight to maximise performance and minimise fatigue?
- What is the fatigue impact of delaying the reporting time for specific duties?
- If I change the number of long-haul flight deck crew on an augmented flight, how will the changed in-flight sleep patterns impact fatigue levels at landing?
- What is the best order in which to schedule disruptive short-haul duties in a run of duties?
An analysis of your schedules to assess alternative scheduling options provides you with an in depth understanding of the levels of schedule-related fatigue. At Clockwork, we have extensive experience of using bio-mathematical models, and have developed a suite of metrics that give you a detailed assessment of schedule related-fatigue. Using these metrics, we can work with you to develop Safety Performance Indicators (SPIs) for schedule-related fatigue, for ongoing tracking within your FRM.
