Especially shiftwork disrupts the sleep-wake cycle, leading to sleepiness, fatigue, and performance impairment, with implications for occupational health and safety. We provide a mathematical fatigue model to approximate the human body’s fatigue level, and we use mixed-integer programming which the shift assignments are described by binary integer to deal with employees’ shift and represent all of the constraints. We also consider every employee’s holiday preference as an objective to meet the preferences of each employee. On the other hand, an optimal solution has been applied to make the peak of fatigue level as low as possible and as far as possible to meet the preferences of each employee. We take a sample with aircraft maintenance crews, air traffic controller, and work-study students schedule to demonstrate the proposed methods.
