About What-If Analysis

A What-If Analysis is a child analysis of a main RBI Analysis (or another What-If Analysis in the Risk Completed state) that allows you to calculate the risk associated with an RBI Component under hypothetical circumstances. What-If Analyses allow you to analyze hypothetical situations to determine how operational and procedural changes would impact the risk associated with a component's failure on a certain date.

When you create a What-If Analysis:

A record of the RBI Criticality Analysis or RBI Pipeline Analysis is created. For the What-If Analysis, however, the value in the Event Type field is populated with the value W.

Note: For a normal RBI Analysis, the value in the Event Type field is blank.
The What-If Analysis is linked to the main analysis through the Has Child RBI Criticality Analysis relationship.
The Consequence Evaluation, Degradation Mechanisms (DMs), and Degradation Mechanism Evaluations (DMEs) linked to the main analysis are copied and linked to the What-If Analysis.
The Analysis ID of the What-If Analysis is in the following format: W <Analysis ID of the main analysis> <Number>, where <Number> is the sequential number of the What-If Analysis.
You can duplicate the What-If Analysis. You cannot, however, apply the What-If Analysis.
You can change the state of the What-If Analysis. The state assignments and operations that are applicable to an RBI Analysis are also applicable to a What-If Analysis.
GE Digital APM copies the values from the fields in the main analysis to the What-If Analysis. However, values in the following fields are not copied:
