CBM Optimization – Complex items An item is a group of components that is convenient to monitor and analyze together Equipment units, as defined in the CMMS asset register are, in general, well defined items. A complex item is an item with more than one significant failure mode.

EXAKT data model These are data mapping tables. They enable the analysis of complex items and are automatically populated by EXAKT in the mapping procedure to be discussed in Slide 5

Attach external database(s) to the analysis

General project data

Data mapping of the first failure mode on Gearbox A

Build the proportional hazard model Age not significant. So fix shape parameter to one.

Final model – reliability is age independent
