We verified the Windowstrade name software application of the Sleep, Activity, Fatigue, and Task Effectiveness SAFTE applied model. The application, the Fatigue Avoidance Scheduling Tool FASTTM was re-engineered as a clone from the SAFTE specification. The verification considered nine sleepwake schedules that were representative of applications of the fatigue model. Of the nine, eight were considered fully verified in the sense that the clones output matched FASTs output well, or the differences in the clone and FAST outputs could be understood as an implementation choice. The ninth schedule was very nearly verified and seemed to require only a minor adjustment to FAST for fall verification. One of the benefits of the verification process was an analysis of how FAST implementation choices impacted predictions relative to simpler implementation choices made by the clone. Most of these implementation differences lead to inconsequential prediction differences however, the difference highlighted by schedule 7 bears farther consideration.
