 In 2005, AFRL awarded a 3-year, Phase 3 SBIR contract to NTI to develop and demonstrate a browser-based, predictive and quantitative fatigue-management software tool for mission planning, crew performance assessment, and status reporting, based upon FAST.A “24/7 Operational Effectiveness Toolset” was developed as an Internet-based tool accessible through a browser, providing support for the scheduling of regular, cyclic work and rest (regularly rotating shiftwork), for irregular work-rest schedules, for the effects of pharmaceutical countermeasures, and for the formal Operational Risk Management (ORM) of fatigue effects.Specific user groups selected for interface design included mission (flight) schedulers, pilots, mishap investigators, and shift work schedulers.
