APPLICATION BEST PRACTICES
CHOOSING THE CORRECT MEASURES AND ASSETS
EQUIPMENT CRITICALITY
The initial step in building a predictive maintenance program is to
identify which systems will be analyzed and prioritizing the order
in which the analysis will take place. To get the most return on the
time invested, the most logical place to start is with the equipment
hierarchy that exists in the Computerized Maintenance
Management System (CMMS). This is typically a breakdown of all
existing equipment from Plant Level to Business Unit to Operating
System to Equipment to Component and to Sub-component,
where necessary.
For a first cut at prioritization for the analysis, it is practical to review the hierarchy at the Operating System level to
determine which systems are
business critical
to the organization.
Business Critical
-
A failure of that specific system at the operating system level would have a direct and immediate
financial impact on the facility output.
For systems deemed critical, a full Reliability Centered Maintenance (RCM) analysis should be performed. One approach to
determine criticality is to use tables similar to those below to assess consequence and probability.
1 Plant
1-1 Business Unit
1-1-1 Operating System
1-1-1-1 Equipment
1-1-1-1-1 Component
1-1-1-1-1-1 Sub-component
