Risks in a Scenario

About Risks in a Scenario

In Asset Strategy Optimization, a Risk identifies one way in which an Asset can fail. If the Risk occurs, the piece of equipment or location will fail, and the system cannot run. In Asset Strategy Optimization Analyses, Risks are stored in System Risks, which can be linked to System Assets and System Switches.

After you create an Action in Asset Strategy Optimization, you can assign a single Risk or multiple Risks to that Action. When you assign a Risk to an Action, a link is created between a System Risk Assessment record, which stores the GUID of the mitigated Risk in the Risk GUID field, and the Action. This allows the Action to mitigate the Risk. An Action may mitigate a Risk by changing certain properties, such as failure consequences or the failure distribution, of the Risk.

Manage Distribution Data for Risks

Reliability Distribution data (Time to Failure and Time to Repair) is associated with Risks. You have two options for defining distribution data for Risks. You can either enter distribution data manually, or associate distribution data from existing Reliability Distribution Analyses and Reliability Growth Analyses.

Define TTF and TTR Distribution Data Manually

About This Task

Time to Failure (TTF) and Time to Repair (TTR) are determined from the distribution data for the associated System Risk record. The TTF and TTR datasheets enable you to define these distribution datasets for your analysis.

Important: This procedure does not work in an Active scenario.

Procedure

  1. Access ASO.
  2. Select a scenario, and then, in the workspace, select the Risks tab.
    The Risks section appears, displaying a list of available risks.
  3. Select the Risk whose distribution you want to define.
  4. In the Risks section, in the grid, the row containing the Risk whose distribution data you want to define:
    • In the TTF Distribution column, select the link.

      -or-

    • In the TTR Distribution column, select the link.

    The TTF Distribution or TTR Distribution window appears, depending on which link you clicked.

  5. Select
  6. When done, select .
    A message appears, confirming that your new distribution data is saved.

Associate Existing Distribution Data with Risks

Before You Begin

  • As an alternative to entering distribution data manually for Risks, you can associate distribution data from existing Reliability Growth Analyses and Reliability Distribution Analyses. When you enter data manually, you can choose any values that you desire for your distribution data, but when you associate existing distribution data with Risks, you use data stored in actual Reliability Growth or Reliability Distribution Analyses.
  • After existing distribution data has been associated with a Risk, you can update the information periodically. When you associate the distribution data, the Entity Key and Family Key of the Reliability Distribution and Reliability Growth Analysis are stored in the System Risk record, thereby establishing a connection between the two records that allows for future updates. This way your ASO Analysis uses the most current information available to calculate the simulation results.
  • You will also need an active Reliability Analytics license to perform this procedure.
    Note: TTR and TTF Distributions can be defined for all scenarios. Also, you can associate Reliability analyses for Active and Non-active scenarios.

  1. Access ASO.
  2. Select a scenario, and then, in the workspace of your choice, select the Risks tab.
