Scheduling Assistant Software: A Tool for Airline Scheduling  (2001)
Abstract Header
"An initial biomathematical model capable of predicting alertness and performance specific to the
aviation environment was used as the foundation for the development of the Scheduling Assistant Software, a software package to aid airline scheduling. The misalignment of the light/dark cycleand the sleep/wake cycle is often accompanied by increased subjective and physiological fatigue, adverse health effects, performance decrements and errors. These effects have been well documented and continue to be a safety concern in flight operations. Pilots on long-haul flight schedules with multiple flight legs and layovers often experience such misalignment of the light/dark cycle and sleep/wake cycle (circadian desynchrony). This desynchronization between the sleep/wake cycle and the local time zone coupled with fluctuations in the amount and timing of light exposure can affect pilots
