This group of key figures refers to the technical objects in Plant Maintenance:

• Functional locations
  System areas, at which a piece of equipment can be installed

• Equipment
  Physical objects which need to be maintained individually

Pieces of equipment can be installed at functional locations on a 1:1 basis (individual installation) or on a 1:n basis (collective installation). This results in the following key figures:

• Total number of functional locations

• Number of functional locations with no equipment installed

• Number of functional locations with a single piece of equipment installed

• Number of functional locations with collective installation

The standard PMIS comes with the following key figures:

• Total pieces of equipment

• Acquisition value of the pieces of equipment

On the basis of these key figures you can obtain further information on the maintenance process (with respect to maintenance notifications, maintenance costs incurred, equipment downtimes, and so on).
