The aim of this study is to present a mathematical formulation that integrates process scheduling and personnel allocation decisions for job shop large-scale plants. This formulation is based on network flows and comprises a large number of variables and constraints, which requires large computational efforts. To circumvent this issue, we propose in this work an alternative solution method with optimal guarantees that evaluates solutions faster for some groups of instances. The performance of the proposed formulation and methods was tested using instances based on an actual industrial-scale facility previously introduced in the literature , . Optimal integrated schedules were obtained using a rolling horizon framework and compared to the case where personnel allocation decisions are not considered together within the process scheduling. The results show that significant improvements can be achieved when using the proposed integrated approach.
