Planned Maintenance
can also be referred to as Planned Preventive Maintenance, Planned Preventative Maintenance or PPM and is concerned with the scheduling of maintenance activities. The most common form of scheduling would be calendar based whereby pre-determined maintenance tasks are scheduled on a daily, weekly, monthly or any other periodicity.
Alternatively Planned Maintenance can be meter based whereby the maintenance tasks are scheduled as determined by a meter reading such as run time in hours or the number of operations undertaken, once a predetermined set point has been reached the maintenance is due.
