Managing fatigue: It really is about sleep.

摘要: Abstract Biomathematical models of fatigue can assist organisations to estimate the consequences a roster before operations commence. These estimates do not account for diversity sleep behaviours exhibited by employees. The purpose this study was develop transfer functions describing likely distributions around level produced commercial biomathematical model fatigue. Participants included 347 (18 females, 329 males) train drivers working railway in Australia. They provided detailed information about their using diaries and wrist activity monitors. On average, slept 7.7 (±1.7) h 24 h work 15.1 (±2.5) h 48 h work. amount obtained shifts differed only marginally across morning, afternoon night shifts. Shifts were also classified into one seven ranked categories estimated scores. Higher score associated with significant reductions shifts, but there substantial within-category variation. findings demonstrate that have utility designing round-the-clock rosters provide sufficient opportunities average employee. Robust variability indicate are relatively poor tools ensuring all employees obtain sleep. importance developing approaches managing behaviour individual
