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.

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
