Create a Deterioration Model

Create a deterioration model to predict failure for your assets.

Before you start, make sure you've set up and published an asset group set to use in the model (only published sets are available). If you plan to use a failure definition, set that up too.

To create a deterioration model:

1. Go to Analysis Deterioration Models and click Create Deterioration Model.

   Or, you could also duplicate an existing model and edit it.

2. Select a System Type (for example, Sanitary Sewer or Water Distribution).
3. Select an Asset Type (Pipe).
4. Select an Asset Group Set. Only published sets appear here - if yours is missing, publish it in the Groups section first.
5. Optionally, select a Failure Definition. Only definitions matching the selected system and asset type are listed, and you can add one later.
6. Click Create Deterioration Model.
7. The model takes a few minutes to initialize. When it's ready, you'll see a table listing all of its asset groups.
8. If you didn't select a failure definition or if some of your groups don't have enough failures to create a curve (at least 5 failures required), you will need to select a survival curve method for each group you want results for.
9. When ready, you can save and run your model.

Deterioration models have three possible statuses:

• Draft: The model has been created but not yet run.
• In progress: The model is initializing or being run.
• Complete: The model is in a ready state.
• Failed: The model run failed.
