InterDynamics (FAID)

In-Depth Analysis

InterDynamics' FAID (Fatigue Audit InterDyne) is one of the most scientifically validated biomathematical fatigue models, endorsed by multiple safety regulators including the Australian Civil Aviation Safety Authority (CASA), Rail Safety Regulator, and National Heavy Vehicle Regulator. FAID calculates a fatigue score (0-150+) based on work/rest history over the preceding seven days, incorporating factors including sleep opportunity duration, time of day (circadian rhythm), cumulative sleep debt, and recovery time between shifts. Scores are mapped to risk categories with thresholds established through research correlating FAID scores with cognitive performance impairment. The FAID Quantum platform enables organizations to prospectively assess proposed schedules before implementation, retrospectively analyze actual hours worked against fatigue thresholds, and manage fatigue risk in real-time using actual clock-in/clock-out data. FAID's strength is its regulatory acceptance — reports generated by the system are recognized by safety regulators as evidence of fatigue risk management, supporting compliance with hours of service regulations and fatigue risk management system requirements. InterDynamics also provides fatigue management consulting services to help organizations design rosters that optimize alertness.
