A Process may consist of a set of alternative sub-processes. Each sub-process can represent an alternative implementation of the process. This allows you to create many variations of a process and keep them organized in one place.
Only one sub-process can be active at any time. For example, you may run an experiment with Alternative Sub-process 1 active, and measure the overall performance of the model. Then you can switch to Alternative Sub-process 2 and compare the results.
SIMPROCESS defines a single default sub-process when you create a new process. If you want to rename the sub-process to something more meaningful for your model:
1. Select it from the Alternative Sub-processes list on the Process Properties dialog.
2. Click Edit to modify the sub-process definition.
3. Highlight the existing name and type over it. For this example, call the sub-process Main.
4. Click on OK.
The new name you specified appears in the Alternative Sub-processes List and becomes the active sub-process.
You can add more sub-processes to the process by clicking on Add and naming the new sub-process. To activate a different sub-process, select it from the Alternative sub-processes list.
Sub-processes can be deleted with the Remove button.
The Copy button will create a new, duplicate sub-process based on the selected sub-process. You will be prompted for a name for the new sub-process, and you may accept the default name.
Click on OK when you have finished defining the properties of the Process.
