- time-based with key date
- time-based as per factory calendar
A Maintenance Strategy can be assigned with Maintenance Packages. The packages of a strategy can have different cycle units (for example month, year). However, they must always have the same dimension (for example time).
The Parameters of a Maintenance Package are the following:
– Package number
– Cycle length
– Unit of measurement
When two packages fall due at the same time, the hierarchy determines which package is carried out.
The offset determines the first due date of a package.
– Preliminary/follow-up buffer
The preliminary and/or follow-up buffer defines the tolerance of the envisaged start and end dates of a package.
Maintenance Task Lists can be created with preventive maintenance in mind. The following steps are required to prepare tasks lists for use in Strategy Maintenance Plans. Where a Maintenance Strategy is defined in the Task List Header.
The different Operations of the task list are then assigned to Maintenance Packages to define the frequency at which the operations need to be carried out.
