Create a Failure Definition

Create a failure definition to define what indicates failure for your assets and improve asset failure predictions in your deterioration model.

If you have sufficient failure data, such as inspections, tasks, or events, you can use this to define what indicates failure for your assets.

Note: Asset groups will need to have had at least 5 failures in order for Info360 Asset to generate a survival curve for the group.

While creating a failure definition is not obligatory, using this data can increase the reliability of your deterioration model. If you don't have sufficient failure data, you will be able to use industry standard curves in your model instead or define the curves manually.

To create a failure definition:

  1. Go to Analysis Deterioration Models and click on Create Failure Definition.

    Or, you could also duplicate an existing failure definition.

  2. Fill out the details and then click Create Failure Definition.
  3. On the configuration page, select the parameters you want to use to define failure for your assets. You can select more than one.

    An asset will be considered to have failed if it matches any of these parameters, and its failure date will be the earliest date any of these occurred.

    • Events: Select any incidents that indicate an asset failed. For example, flooding, bursts, blockages, etc.

      Select the date field you want to use (e.g., opened date).

    • Inspections: Choose defect codes and/or condition scores that indicate failure. For example, defect codes such as collapse, break, etc. or a severe overall condition score.

      See more about condition scores.

    • Tasks: Tasks are maintenance or repair activities that have been performed on assets. If certain types of repairs were necessary, this may indicate that the asset failed. For example, relining, replacement, etc. You can add any tasks that indicate asset failure.

      Select the date field you want to use (e.g., scheduled date).

  4. If you select parameters in multiple categories (events, inspections and/or tasks), you can prioritize one category over the others to determine the failure type/date. For example, you might want to prioritize inspection data that indicates a failure, even if there are failures in other categories that occur earlier.

    Use the 'Prioritize this failure type if multiple failures exist in an asset' option.

  5. Then select Run and the results calculation will begin. This may take a few minutes.
  6. For each asset that has failed, you will see the age at failure, the failure date and the failure type. You can filter, sort, and export these results. You can now use this failure definition in your deterioration models.

Failure definitions have three possible statuses:

  • Complete: The definition is in a ready state. This status does not necessarily mean that the definition has been run (that is, there may not be any results yet).
  • In progress: The definition is initializing or being run.
  • Failed: The definition run failed.
