Description
Summary:In this article a new model is developed to deal with safe skill-based job rotation scheduling (SSJRS). A multiobjective integer programming model is presented to determine job rotation schedules which considers two objective functions simultaneously. The first objective function aims to minimize maximum occupational noise exposure injuries, and the second one is designed to minimize the potential of worker’s low back injuries. The potential of worker low back injuries and the noise exposure levels of each job are assessed by job severity index (JSI) and daily noise dosage (DND), respectively. Thresholds for JSI and DND are also considered in the model. Finally, this model is solved as a single objective model, using the LP-metric method. To verify the efficiency of SSJRS, test problems are solved for each objective of the model separately, and the results are compared with the results from the SSJRS model. It has been found that the results from the SSJRS model dominate the results from single objective models.
