ABSTRACT (maximum 200 words) This thesis investigated the validity of the Royal Australian Navy’s proposed Navy Standard Work Week (NSWW) model and the Navy Management Diary (NMD) with its accompanying fatigue measurement tool. A simulated 21-member Armidale Class Patrol Boat (ACPB) crew was constructed in the NMD to assess the NSWW. The NMD fatigue measurement tool and the Sleep, Activity, Fatigue and Task Effectiveness (SAFTE) model, and its software instantiation, the Fatigue Avoidance Scheduling Tool (FAST), were used to estimate risk for the periods of activity across the three weeks, resulting in comparison of the associated risk levels identified by the NMD fatigue tool and corresponding FAST scores. In the proposed RAN NSWW model, the category of maintenance most often exceeded its allocated hours, leading to the recommendation that further research on a larger sample might address whether the proposed NSWW should be customized to be platform and occupation specific. The NMD and FAST software tool comparisons resulted in statistically significant differences in predicted risk. The discussion speculates on why these discrepancies exist between the two software tools. The thesis recommends that this methodology be replicated using a larger sample and include empirical observations of performance in actual operations before comparing to FAST-generated predicted effectiveness levels. 14.
