Who we are

Fatigue Risk Management System (FRMS)

We assist you through all the phases of your fatigue risk management system implementation.

Workload assessment

We have developed a scientifically valid method for measuring workload, usable at different levels of your design process.

Psychosocial risks prevention

We help you to assess and prevent psychosocial risks within your organization.

“The implementation of a fatigue risk management system increases your operational flexibility and your performance, while preserving a high safety standard.”

Philippe Cabon, university lecturer and researcher, cofounding partner of Welbees



  • Provide operational support for the implementation of your risk management system: data collection; identification of specific activity-related risks; risk mitigation countermeasures; and effectiveness assessment.
  • Training

  • Raise awareness and further educate on individual human factors and fatigue management.

  • Train supervisors on risk assessment methods and tools.

  • Raise awareness of scientific methodologies used for data collection and analysis.

  • R&D

  • Conduct scientific research as part of the design project aimed at industrial risk prevention.

  • Develop an innovative data analysis approach for better industrial risk prediction.

  • Main Sectors of Activity

    We are experts in human factors and safety with extensive experience in fatigue in aviation and other key safety-critical industries. We aid all organisations that face difficulties surounding fatigue and risk management.

    6th International Human Factors Rail Conference

    We took part in the « 6th International Human Factors Rail Conference », organised by RSSB and held on the 6-9 November 2017 in London, England, to bring our expertise on the following subjects:

    • Preparing rail industry guidance on biomathematical fatigue models (Somvang V. et al., 2017)
    • An innovative methodology to evaluate workload (Cabon P., Somvang V., 2017)
    10th International Conference on Managing Fatigue

    We took part in the « 10th International Conference on Managing Fatigue » held in San Diego, USA, on 20-23 March 2017 to present two projects :

    • Relative merits and limitations of biomathematical models for fatigue prediction: a comparative study (Somvang V. et al., 2017)
    • Effects on Reduced Rest and Early Start on Crew Sleep and Fatigue in French Regional Airlines (Cabon P., Somvang V., 2017)

    Did you know?

    Since the invention of electricity, people sleep
    around one hour less than their natural need.
    Easy access to electricity and artificial light has triggered a measurable reduction in human sleep. Indeed, people living in industrialised societies, having access to activities such as the internet, watching TV, etc. tend to stay awake even after darkness, when their biological clock suggests them to sleep.
