A multi-criteria genetic algorithm for the generation of job rotation schedules

A genetic algorithm for the design of job rotation schedules considering ergonomic and competence criteria

“…Within the evolutionary computation algorithms, GA is especially efficient at solving combinatorial optimization problems. GA provides reasonable solutions to the job rotation scheduling problem without excessive computing time [12,20]. GA performs a guided stochastic search by constructing the evolution of certain structures (called individuals) that represent the solutions to the problem.…”

“…In other words, the model should consider the jobs assigned to the worker in previous rotations to avoid fatigue accumulation. For this end the procedure described in Diego-Mas et al [20] was used. The procedure consists of changing the ergonomic scores of the worker to obtain a different value for each rotation in a way that it reflects the effects of the tasks performed in previous rotations (the values of the job scores will be constant in all the rotations).…”

“…In previous works, this problem was solved using integer programming [6,[12][13][14][15][16], heuristics [17], metaheuristics such as genetic algorithms [6,12,15,[18][19][20], simulated annealing [15,21] or ant algorithms [22] or by combining integer programming and metaheuristic models [6,15]. In these studies, rotation schedules were developed for different purposes.…”

“…al. [20] presented a genetic algorithm for the generation of rotation schedules to prevent the accumulation of fatigue caused by repetitive motion. Azizi et al [6] studied the effect of job rotation on worker's skill learning and forgetting.…”

Effectiveness of job rotation for preventing work-related musculoskeletal diseases: a cluster randomised controlled trial

“…In the absence of this evidence, the most appropriate approach is to use the systematisation of studies 10. To meet these goals, job rotation implementation in a manufacturing industry must include: acceptance and involvement of managers and workers; assessment of the job characteristics (demands, biomechanical exposure levels, autonomy) and the production method; choosing the number of employees per task; and definition of criteria and parameters that will be used to generate a job rotation schedule 1 11 12. Training all workers according to their competences before implementing job rotation is also important 8…”
