The Fatigue Risk Index

A bio-mathematical model for employees exposed to fatigue hazards when working shift rotations

The industry-leading Fatigue Risk Index (FRI) is used across a range of industries including emergency services, aviation ground crew, manufacturing, rail, energy and maritime.

FRI become available in the year 2000 and is a popular Risk Management tool used for shift workers. It is a popular model used for fatigue management for shift workers, supporting safety and operations managers in their obligations to reduce fatigue hazards and improve productivity across many industries.

FRI was originally commissioned by the UK Government Health & Safety Executive (HSE). FRMSc has enhanced the speed, power, connectivity and user experience into the FRI+ model. FRI+ provides identical outputs to the original version but with a significantly improved interface, increased schedule capacity, a more robust approach and a better user experience.

Our enhanced FRIPRO will be released soon. It has been designed to meet the needs of the FRM or Safety Manager. FRIPRO includes many of the features available in the SAFE and CARE aviation models including variable workload, fatigue scores every 15 minutes of duty and visible sleep periods. FRIPRO can also be connected to the HARVEST analytics package for greater oversight and analysis.

FRI+ has a comprehensive set of features including:

FRIPRO enhances FRI+ by including:

FRI+ model provides scale, speed and security

rail industry approved

Used across the Rail Industry

Commissioned by the UK Health and Safety Executive and used extensively in the rail industry.

easy to use

Targeted Model

Developed from decades of original research and used extensively for shift work. Supports in-duty breaks and time on task variables.

fast and flexible

Fast, scalable & API-ready

FRI+ and FRIPRO are hosted on scalable cloud systems allowing thousands of schedules to be analysed rapidly. APIs available to connect with scheduling and timesheet software systems.

adaptive

Operationally relevant

Supports “what if” scenarios to test new operational models and working patterns to meet varying workload and staff availability.

Intuitive user interface

User interface provides visualisation of fatigue and risk profiles, manual editing of rosters for fine tuning and detailed analytics

Cost effective

The FRI+ and FRIPRO biomathematical model platform provides unparalleled cost/performance for analysing fatigue in shift worker schedules.

Using the Fatigue Risk Index

FRI+ can be tailored to specific occupations across different industries.

FRI+ uses updated algorithms and user interfaces on a powerful cloud hosting platform to provide you with a better and faster experience using the same fatigue and risk metrics of the original FRI model.

Rosters can be uploaded directly or integrated into rostering systems to take an automatic feed for analysis. Workload and alertness levels can be varied for each duty to take into account job and task differences.

The FRI+ output has also been enhanced providing more detailed outputs as well as the ability to optimise schedules within the user interface.
