 Performance-Based Maintenance Plan

Definition

With performance-based maintenance plans, you can plan regular maintenance based on counter readings maintained for measuring points at pieces of equipment and functional locations. To represent simple maintenance cycles, you can create a single cycle plan . To represent complex maintenance cycles, you can create a strategy plan based on a performance-based maintenance strategy .

Assign a counter to the maintenance plan. Maintenance takes place when the counter for the technical object has reached a certain reading, for example, every 100 operating hours, every 500 moulding cycles. The calculated planned date depends on the counter reading at the time of planning, and the estimated annual performance that has been defined for the counter.

Counters are represented in the Plant Maintenance (PM) application component as a special form of measuring point. For more information about counters and measurement documents ( = counter readings), see Counters and Measurement Documents in the Measuring Points and Counters component.

Use

You can use performance-based maintenance planning, for example, to ensure for the maintenance call object , maintenance order (PM order), that the operations contained in the maintenance task list are performed at a time when the technical object actually requires maintenance.

For performance-based maintenance planning, it is important that you enter the current counter reading regularly, even if it has not changed. Otherwise, the system generates call objects (for example, maintenance orders) based on the estimated annual performance entered for the counter, even though the counter reading has not in reality been reached.

Example Example

A pump requires a maintenance task to be performed every 100 operating hours. The call date calculated when the maintenance plan was scheduled is almost due, but the counter reading for the pump indicates that it has only been in operation for 50 hours (for example, owing to a temporary shutdown).

To avoid a maintenance order being created before it is needed, you maintain the new total counter reading in the system. You then reschedule the maintenance plan, and the call date is recalculated based on the updated counter reading. In this case, the call date would be later.

End of the example.

Structure

A performance-based maintenance plan must comprise the following parts in order for it to be scheduled:
