Goals of this lesson
- Usage of subprocess activities
- Considering the differences between configuring models and subprocess models for simulation purposes
How-to
Model 9 mainly consists of two activities, of which the first one is a Subprocess Activity. Subprocess activities are special because they contain another simple BPMN model, which will be executed in the activity's life-cycle.
Approach
- Click the first activity (which should be a subprocess activity)
- If the activity is not a subprocess activity, then select Subprocess from the Element Type drop-down-box under the General Properties
- Now click the Set button next to the Subprocess property under Subprocess Properties
- Note: This option is only available in the Modeling Property Set
- IYOPRO's File Browser shows up and you can select the model, which functions as the subprocess
- There is still one thing to understand
- Subprocess activities do not contain any duration properties
- You have to make sure that your Subprocess model is simulation-ready configured
- Important: The start events of Subprocess models must not have an inter-arrival time assigned
- But all the other (allowed) elements like gateways and activities still need to be configured
- You may also use variables, which are known to the subprocess activity in which the model is being executed
- e. g. for decision making at gateways
