Simultaneous scheduling of production and maintenance in a flexible job-shop workshop
Résumé
This paper proposes an integer linear program for joint and simultaneous scheduling of production and predictive maintenance tasks based on degradation prediction. The objective is to find a scheduling scheme that minimizes the total execution time while guaranteeing that the state of the machines is maintained below a predefined degradation threshold. Experiments are performed on randomly generated instances. The first results justify the interest of this approach from the production and maintenance cost points of view.
