Model Window

The Model window consists of two tabs:

The Main tab allows you to configure the main properties of the model.
The Identifiers tab allows you to enter additional identifying information that can be used to search for this resource.

The following settings are available on the Main tab to configure the model:

The Model Name field allows you to specify a name for the model. You can replace the default name with your own name of up to 150 characters, if desired. See Default Name Formats.

In the Model Category field, you must specify what category of behavior the model represents (i.e., reliability, probability of failure, event occurrence, duration, cost or cost per unit time), thereby restricting where and how it can be used. Once a model has been created, you cannot change its category.
In the Model Type field, specify whether the model is constant or varies with time (i.e., a distribution).

For constant models, enter the fixed probability, duration or cost value. The type of value that you enter is dependent upon the model category. For duration models and cost per unit time models, you will also need to enter the time units that the model uses.

For distribution models, select the distribution and specify its parameters. You can:

- Select a distribution from the drop-down list and then enter the required parameters, which will vary depending on the selected distribution. (For a list of the available distributions and their required inputs, please refer to the Models topic.)
- Click the QPE icon to use the Quick Parameter Estimator (QPE), which helps you to choose a distribution and/or solve for the distribution’s parameters given limited information.

Information about the creation and last modification of the model is displayed at the bottom of the tab.
