Abstract Shift work disrupts the sleep-wake cycle, leading to sleepiness, fatigue, and performance impairment, with implications for occupational health and safety.
For example, aircraft maintenance crew work a hour shift rotation under the job stress of sustaining the flight punctuality rate. If an error occurs during the aircraft maintenance process, this error may become a potential risk factor for flight safety.
This paper focuses on optimal work shift scheduling to reduce the fatigue of shiftworkers. We proposed a conditional exponential mathematical model to represent the fatigue variation of workers.
The combined problem is formulated as a mixed-integer program, in which the shift assignments are described by binary variables.
Using the proposed method, we can find a feasible work shift schedule and also have a schedule that minimizes the peak fatigue of shiftworkers while satisfying their days off demands.
Several examples are provided to demonstrate the effectiveness of the proposed approach. Fatigued drivers will cause substantial danger to the road safety [ 4 ]. Most hospital nurses work extended hours, and long work hours are found to be a contributor to poor patient outcomes, such as errors and infections, and poor nurse outcomes, such as musculoskeletal and needle stick injuries [ 5 ].
These show the importance of keeping a good working state to reduce accidents. Therefore, it is important to schedule an appropriate shift table that takes the reduction of fatigue into consideration.
The mechanism behind fatigue is complicated.
Previous research has shown that fatigue increases along with the length of shift length, with associated increases in the likelihood of accidents occurring. This study found that when returning to bed in the morning, night workers fall asleep rapidly but are prematurely awakened by their circadian rhythm and exhibit severe sleepiness and reduced performance capacity.
With regard to people working morning shifts, the circadian psychophysiology makes it difficult for them to fall asleep as early as needed.
Process S increases during waking and decreases when sleeping. Various linear and nonlinear interactions between Process S and Process C have been proposed and studied [ 8 ]. Dawson and McCulloch [ 9 ] stated that fatigue and fatigue-related impairment are influenced by previous sleep quality, time spent at work, and length of time spent awake.
The results also indicate that, in addition to sleep length, wakefulness, and work hours, workload significantly influences fatigue.
These indicate that work shift and workload are possible causes affecting fatigue.
To automatically arrange a feasible shift table, the scheduling problem is usually formulated as a constraint program. The hard and soft constraints are defined according to the importance of each constraint.
Fatigue simply cannot be eliminated within the modern aviation world, and therefore must be managed in a systematic way. This online course will give you a high level understanding of fatigue management in the aviation sector and the processes recommended to manage fatigue. As world leaders in aviation safety, we like to challenge the norms and push back the barriers to understanding aviation safety issues.

That is, the objective function measures how much the solution deviates from the soft constraints. Two different techniques, the sequential technique and the equivalent weights technique, are proposed to solve the nurse scheduling problem.
Using similar formulations, Kundu and Acharyya [ 13 ] proposed a satisfiability approach to solve the nurse scheduling problem with comparisons with simulated annealing approach and genetic algorithm approach.
Kim and Lee [ 14 ] considered the problem of managing work shift for nuclear power plants. The objective function is to minimize the work time differences among all employees, and a heuristic method is proposed to solve the problem. Human factors, such as work and rest time regulations, are considered in the constraints.Managing aviation maintenance organizational errors and risks - A focus on the importance of safety awareness to enhance performance - Kok Meng Chan - Research Paper (undergraduate) - Sociology - Work, Profession, Education, Organisation - Publish your bachelor's or .
The FAA and Transport Canada offer a number of fatigue management resources on their Web sites, including complete fatigue management toolboxes. Figure 3: Fatigue-awareness posters from the FAA The FAA has produced a series of educational posters designed to bring awareness to human fatigue in aviation maintenance.
