Abstract
The objective of this task was to compare and analyze sleep mdoels results versus experimental data which were collected on sailors' work, rest schedule and fatigue onboard a Royal Canadian Navy vessel. This study is a continuation of the analysis presented in a previous report [1] with a new set of experimental data. Model predictions of Day workers' sleep were accurate; however, sleep prediction of Night workers were less satisfactory. Optimization algorithms were applied to the mathematical model to improve the accuracy of the predicted results of nightshift workers relative to the experimental results. The following two sleep prediction models were considered and analysed: the Two-Process Model of Sleep Regulation (Model 1) by Acherman and Borbley [2] and the Three-Process Model of Alertness (Model 2) by the Akersted's group [3]. A third model, the Sleep/Wake Model by Darwent's group [4] was investigated [1,5] but not considered in the present study due to its low accuracy in comparison with Model 1 and Model 2.
