Custom RBI Methodology Preferences

About Custom RBI Methodology Preferences

The consistency of the approach used to create RBI Analyses is vital to comparing results from one assessment to the next. Using Custom RBI Methodology Preferences, you can customize Degradation Mechanism Evaluations to incorporate custom aspects of RBI and to create custom RBI Analyses that will best suit your organization.

Benefits of Custom RBI Analyses

Using Custom RBI Analyses, you are able to:

  • Add calculations for custom DMs (DF or POF) or an existing DM without having to edit rules.

  • Reduce implementation time.

    • Achieve results through Policies and R Scripts

    • Avoid the need to write rules to perform custom calculations.

  • Expedite the Database upgrade process.

  • Use a combination of custom DMs and add existing Criticality Calculator DMs to calculate RBI Analyses

Using Custom RBI Analyses

Based on the maturity of various organizations across the globe, these organizations may choose to develop their own RBI methodology. Using Custom RBI Analyses, users of GE Digital APM will be able to build RBI methodologies to best suit their organizational needs.

Every RBI analysis consists of a Damage Mechanism Evaluation (DME) and a Consequence Evaluation (CE). Using Custom RBI Analyses, you will be able to configure Custom DMEs for RBI Criticality Analyses.
