Configure Consequence Evaluation Validation and Calculation

About Consequence Evaluation Validation and Calculation

When you calculate an RBI Criticality Analysis, it gives you the Consequence of Failure (CoF) value based on the values in the consequence evaluation fields. You can now configure this calculation based on your requirements. These calculations override the baseline calculations. The following image illustrates the flexible CE calculation framework:

Workflow

This topic describes the overview of the tasks that you need to perform to configure the flexible CE validation and calculation. Based on the complexity of the configuration, you may need to perform certain tasks outside of the Risk Based Inspection module . When performing such tasks, we recommend that you follow the documentation of the respective modules.

The following image illustrates the typical workflow of the flexible Consequence Evaluation calculation configuration:



Note: To configure flexible CE calculation, it is not mandatory to perform all the tasks mentioned in the workflow. You can perform only the tasks that are specific to your configuration. For example, if you want to configure only the CE Calculation using the baseline CE family, you can perform only the following tasks:
  • Configure CE calculation policy.
  • Create Calculation Configuration in RBI Application Settings.
If you do not want to use the baseline CE family and want to use a new CE family for the flexible configuration, you must complete the following tasks before configuring the validation and calculation.

Create a Consequence Evaluation Family and Datasheet

About This Task

If you want to use a new family to configure the flexible CE calculation, you can create a child family under the Criticality Consequence Evaluation family. This is not a mandatory step to configure the flexible CE calculation. However, if you want to use new fields for the calculation that are not part of the baseline family, we recommend that you create a new family and do the configuration. This will make sure that the baseline family is not modified, and you can use the baseline family whenever required.

For more information on creating and configuring a family, refer to the Family Management documentation.

Create Relationship between RBI Criticality Analysis and CE Family

About This Task

If you have created a family as part of the flexible CE calculation, you must create a relationship definition between the RBI Criticality Analysis family and the new family.

This topic describes the basic steps to create a relationship definition between the RBI Criticality Analysis and the Consequence Evaluation family. For detailed documentation on creating relationship definitions, refer to the Family Management documentation.

Procedure

  1. Access the Has Consequence Evaluation Relationship Definition. For information on accessing a relationship family, refer to the Access the Relationship Definition Section topic.
  2. Create a One-to-Many Relationship Definition between the RBI Criticality Analysis family (Predecessor family) and the new CE family (successor family). For information on creating a relationship definition, refer to the Create a Relationship Definition topic.

Link Potential Degradation Mechanism to Consequence Evaluation Family

About This Task

If you have created a family as part of the flexible CE calculation, you must link the family to the applicable Potential Degradation Mechanism (PDM) records. This topic describes the steps that you need to perform to link the family to a Potential Degradation Mechanism. For more information on Potential Degradation Mechanisms, refer to the About Potential Degradation Mechanisms (PDM) topic.

Procedure

  1. In the record manager, select the datasheet of the Potential Degradation Mechanism that you want link to the family.
    The Potential Degradation Mechanism datasheet appears, displaying the General section.
  2. Select Consequences.
  3. In the Consequence 1 row:
    • Select a failure mode in the Value(s) box.
    • Select the new CE family in the Consequence Eval Used box.


  4. Select .

    The potential degradation mechanism is linked to the configured Consequence Evaluation family.

Create CE Validation Policy

About This Task

As part of the flexible CE calculation, if you do not want to use the baseline validations and want to use new validations, you can create a new validation policy. If you use a configured validation policy, it overrides all the baseline validations. After you create the validation policy, you must configure the policy in the Flexible Calculation Validation section in RBI 580 Flexible Calculation Preferences page.

This topic describes the basic steps on creating a validation policy. For more information on creating, managing, and activating policies, refer to the Policy Designer documentation.

Procedure

  1. Create a policy.
  2. Access the Design workspace of the policy.
  3. Add an Entity node that represents the family that you want to validate. For more information on Entity nodes, refer to the Entity Nodes in Policy Designer topic.
  4. As needed, add other nodes required for the validations. For more information on the different types of nodes, refer to the Condition, Logic, and Calculation Nodes in Policies section in the Policy Designer documentation.
  5. For each validation, add a Return Value node that has the error message that you want to display to the user when validating the policy. For more information on Return Value node, refer to the Return Value Nodes in Policy Designer topic.
    Note: Each Return Value node must have a unique name and the error messages must not contain more than 255 characters.
  6. Save the policy.
    The analysis validation policy is created.

Configure Consequence Evaluation Calculation - Example

About This Task

Suppose you want to configure a Consequence Evaluation calculation such that based on the value in the Production Loss field, an output field, Lost Production Category is updated with a value. The Production Loss field must have the following properties:
