Multiple Counter Plan
Definition
A multiple counter plan is used in counter-based (performance-based) maintenance. This type of maintenance planning is not based on a maintenance strategy. This means that you create a multiple counter plan without a maintenance strategy .
In the multiple counter plan you create maintenance cycles and allocate counters of equipment or functional locations with different dimensions to them, for example, flight hours, number of take-offs and landings, kilometers travelled. You can also integrate time-based cycles into the maintenance plan. However, these do not have counters. Alternatively, you can also create a multiple counter plan with a cycle set as a copy model for maintenance cycles.
For the call objects , maintenance order (PM order) or service order, you can describe the necessary activities using a maintenance task list , which you assign to the maintenance item .
Note
If you use a multiple counter plan, all the operations in the task list are copied into the maintenance call object , maintenance order or service order, when maintenance is due. You should consider this when planning and preparing maintenance tasks.
If you schedule the multiple counter plan, the system calculates the planned deadlines for each maintenance cycle on the basis of the current counter reading and the estimated annual counter activity. (For a time-based cycle, the system calculates the deadlines on the bais of the time unit and the cycle duration.)
The cycles for a multiple counter plan are linked with either an OR operation or an AND operation. For an OR operation , a maintenance order is generated for the earliest possible planned date. If maintenance is due, for example, every 100 tons produced or every 50 operating hours or every two weeks, the decisive factor is which occurs first .
For an AND operation , a maintenance order is generated for the last planned date. If maintenance is due, for example, every 100 tons produced or every 50 operating hours or every two weeks, the decisive factor is which occurs last .
Note
For multiple counter plans, you can activate additional functions , such as cycle set sequences, and other scheduling parameters.
Use
Multiple counter plans are best suited to individual activities or individual groups of activities, for example, in the airline industry, if the frequency of inspections of the landing gear should depend on the number of kilometers flown and the number of take-offs and landings.
Structure
A mutiple counter plan must comprise the following parts in order to be scheduled:
