A Process Model Simulator is a Microsoft Excel workbook, reproducing one of the process models of an open case. You can build process model simulators to examine and edit process models outside Plan, and to produce results from one or more input datasets.
This workflow shows how to create a Process Model Simulator:
-
Open the selection dialog
Click the Create Process Model Simulator button in the Model Build group of the Integration ribbon tab.

The Select A Process Model dialog window opens. This window lists all the process models used in the case.
-
Select a model
Click any cell in the row of the model for which you want to create a simulator. A small triangular arrow appears to the left of the row, indicating that it has been selected. You can select only one row at a time.

-
Choose number of datasets
The Number of Datasets field at the bottom of the window shows how many datasets will be available in the Excel simulator. Change the default value of five if needed.

-
Create the simulator
Click OK. The simulator workbook is created and opens in Excel.

Tip: You can quickly create a simulator for a process model by double clicking the corresponding row.
-
Review the model simulator
Review the model inputs and outputs in Excel.

Note: If a base name is made entirely of numeric characters, an exclamation mark is added at the beginning of the corresponding worksheet name. For example, the worksheet for base 50 would be called !50.
-
Change simulator inputs
Change the model inputs and review the changes in the output predictions.

-
Save the simulator
Note that the simulator is created as a temporary file and is not saved to disk. Make sure to save the workbook before closing Excel.
