Setting up Probability Evaluation Score Sets

A probability score set assigns scores for each of the probabilities defined for the enterprise. You can define as many different score sets as required by your organization and assign them in risk analysis options for analysis types, asset types, and individual analyses.

Score sets make it possible to evaluate assets based on their material type or classification. For example, the Corrosion Under Insulation failure mode can have different probability and severity score sets depending on whether the asset is fabricated from carbon steel or stainless steel.

To Set up a Probability Evaluation Score Set

1.	From the Site window, select the Strategy Development view, Settings tab and then the Probabilities tab. Select the Probability of Failure Settings node in the tree.

Tip: You can also select the Administration menu, Strategy Development Settings, Risk Analysis, and then Probabilities. The Strategy Development - Probability of Failure Settings dialog appears.

2.	Select the Score Sets tab. For example:

Note: You can prevent a score set from being used while it is in development. Select it in the table and click Mark as Inactive. When it is ready for users, mark it as active again.

3.	Click New. The Risk Evaluation Score Set dialog appears.

5.	For each probability that the set will use, click New. The Risk Evaluation Score dialog appears:

6.	Enter the following information:

Setting Name

Description

Probability

The failure probability to which this score applies.

Score

Positive number that indicates the relative weighting of the probability or severity. Zero indicates no effect. The larger the number, the higher the impact.

7.	In the Description box, provide a brief name for the score. You can provide more information in the box below it.

8.	Click OK to close the Risk Evaluation Score dialog. The score is added to the table.

9.	When you are finished adding scores, click OK to close the Risk Evaluation Score Set dialog. The score set is added to the table.
