Companies sometimes miss opportunities to pursue long-term people-related targets despite short-term performance targets. There is a lack of a measurable variable that shows possibilities for the pursuit of person-related targets. This paper will therefore present an approach based on a simulation-based robustness analysis that makes it possible to integrate long-term targets into production planning. By identifying critical workplaces and determining the tolerable change in the planned personnel deployment, possibilities are shown for pursuing long-term people-related targets.
