Using Biomathematical Models to Assess Rosters for Fatigue

Many companies in the rail industry use tools, such as the Fatigue and Risk Index, to estimate fatigue risk from different work patterns. These tools, which are based on biomathematical models (BMMs), can be very useful if they are used correctly. But if they are misunderstood or misused, that can have a big impact on workers’ fatigue, their safety, health, livelihoods and families.

Our research in this area focuses on enabling the rail industry to reduce the risk of designing fatiguing rosters. The results of our analysis of BMMs based on industry needs is available to organisations to inform the selection of tools to support fatigue management.
