Maintenance policy

Maintenance-window frequency (days between): 14

This case study models a 20-machine production line over a 90-day quarter. More frequent scheduled maintenance windows prevent more unplanned breakdowns, but each maintenance window pauses production for the machines involved, and there is a real cost to visiting machines more often than they need.
