Although the fourth industrial revolution has greatly accelerated the automation of production processes, the importance of human resources has not diminished, as evidenced by the fact that multinational companies are increasingly investing more and more effort in determining the optimal allocation of machines and operators. In this paper, the authors present an approach to the operator-machine assignment task through a suitable model. The mathematical model presented issuitable to support the design of an appropriate human resource management strategy and the implementation of operative human resource management tasks in production systems of different sizes.
