Example of Maintenance Plan Costing

In this example, maintenance plan costing is performed for a one-year analysis period from 01.01 to 31.12. The strategy assigned to the maintenance plan contains two maintenance packages:

  • Package 1: Every month (1M)

  • Package 2: Every three months (3M)

The following calculations take different package hierarchies .

Determination of the frequency for Calculation 1

Package 2 belongs to a higher hierarchy than package 1.

Package

Due Date

Frequency

Special Features

Package 1

1M

8 times

Packages 1 and 2 are due at the same time four times. Because only the packages with the higher hierarchy number are executed, package 1 is omitted when two packages are due at the same time.

Package 2

3M

4 times

 

Determination of the frequency for Calculation 2

Package 1 and package 2 belong to the same hierarchy.

Package

Due Date

Frequency

Special Features

Package 1

1M

12 times

Packages 1 and 2 are due at the same time four times. The same package hierarchy means that both packages are always due. In this case, neither package is omitted when both packages are due at the same time.

Package 2

3M

4 times

 

Determination of Costs

  1. The system totals the maintenance calls determined for a specified analysis period (= frequency) for each scheduling combination.

  2. The service simulates a maintenance or service order for each maintenance call.

  3. The costs to be expected are derived from the multiplication of quantities and values (for example, (internal/external service, required materials) and the determined frequency.
