Select a baseline analysis

In Analysis Settings, when configuring a detailed loss analysis, you can save a significant amount of runtime and database space by selecting an existing loss analysis as the baseline analysis in the Flexibility area

Flexibility options include: loss modification factors, custom vulnerability damage functions, custom frequency catalogs, and baseline analysis. You can select all the options.

When you specify a baseline analysis, savings occur because the loss engine does not have to run AIR's original view again. This feature is useful if you want to see the effect of different flexibility options on the original loss analysis results. In this case, the subsequent loss modification uses the same settings as those used during the selected baseline analysis.

You can use a baseline analysis only after running AIR's original view once. This restriction prevents a redundant run of AIR's view.

Procedure

  1. Create a new detailed loss analysis.
  2. In the Analysis Settings pane, navigate to the Flexibility area.
  3. Select the flexibility feature you want to use.
  4. Choose whether to generate a standard AIR detailed loss analysis result in addition to the custom loss result. This option is selected by default.
  5. In the Baseline Analysis list, select the baseline analysis that you want to use.
    If you change any of the loss analysis configuration options after selecting a baseline analysis, the system prompts you that it will create a new baseline analysis. This ensures that the criteria for the analyses are the same in the baseline view and the modified view.
  6. Finish configuring the detailed loss analysis and then run the analysis.
  7. Repeat the steps in this procedure as often as you want in order to see the results of different flexibility features on the baseline analysis.
