2B-Alert for Operational Fatigue Management

2B-Alert is a decision tool designed to help enhance cognitive performance in operational settings. The tool uses established sleep/wake patterns to predict caffeine effectiveness, tactical nap effectiveness, and performance. In addition, it can provide caffeine dosing schedules for time periods where performance is most critical. Sleep optimization prediction has been developed and will be integrated into the application in the future.
