Have a look at this Aircraft Fleet Maintenance Model built using ExtendSim.
The aircraft have a number of attributes one of which is hours on airframe. Model tracks flying hours and routes aircraft to scheduled maintenance events when required by accrued hours. Aircraft can be sent on different types of missions; ie. special deployment, deployment, and local flying operations.
There are six types of scheduled maintenance of different durations. Aircraft are unavailable for deployment or other flying operations while they are in maintenance.
Unscheduled maintenance with Mean Time Between Failures (MTBF) and Mean Time To Repair (MTTR) could also be modelled, but they're not included in this particular demo model.
Key outputs include an aircraft instance table, aircraft maintenance log and location assignment log.
