Expectations from industry and the community ensure that we live in a 24-hour society. Increased demand for flexibility, capital utilisation and competition have initiated or extended shiftwork operations in many industry sectors such as mining, transport, defence, healthcare, manufacturing and security. The most common problems reported by shiftworkers are disturbed sleep and sleepiness. From a biological perspective this is not surprising because shiftworkers are often required to work at times when their mind and body are driven toward sleep. Shiftworkers may therefore be required to attempt sleep during the day; a time at which their mind and body are programmed to be awake and active. When sufficient recovery doesn't occur regularly, sleepiness and fatigue can accumulate. Traditionally, shiftwork and the work-related fatigue that it can create have been 'managed' by limiting the length of shifts and total number of hours worked per week, month or year. However, this approach fails to acknowledge key factors such as the time-of-day of work. Thus, the aim of this thesis is to provide the background, components and preliminary validations of a model to assess hours-of-work and fatigue in a scientifically appropriate manner. / thesis (PhD)--University of South Australia, 1999.
