The purpose of the FASTTradeMark Phase II effort has been to enhance the SBIR product. This was accomplished by adding features to the Fatigue Avoidance Scheduling Tool FASTTradeMark, which contains a highly researched and recognized model of human sleep and cognitive performance and by conducting studies to acquire new data and to valid the model perditions. The Fatigue Avoidance Scheduling Tool FASTTradeMark allows a user to predict cognitive performance and effectiveness based on the timing and amount of sleep an individual or team receives prior to and during a mission. FASTTradeMark provides the military planner the ability to optimize performance under conditions of limited sleep, thus minimizing the need for pharmacological aids while indicating work periods where additional fatigue countermeasure may be necessary. This report describes the rationale for adding features such as shifting the circadian rhythm for shift work or transmeridian travel, automatically inserting sleep into a schedule when no data are available, predicting lapses of attention, an algorithm to predict the impact of simulants on performance, a window showing levels fatigue factors affecting performance at any time within a schedule, and an algorithm to predict performance variability. The report also describes plans for future work that will develop new fatigue management tools. Part 2 of this report describes new interface designs for irregular schedules and shift work schedules as well as field study validation of the model predictions.
