Simulating BPMN models

In IBM® Rational® Software Architect Designer 8.0.2 and later, you can simulate Business Processing Modeling Notation (BPMN) models to visually debug them. Simulating a business process model is similar to simulating an UML activity diagram; both simulations share the same notations and decorators. A BPMN process is not automatically instantiated when its execution starts. The BPMN process is instantiated when one or more start events are triggered. If a model execution session starts from a process, you are prompted to specify which start events to use if there are more than one. You must select at least one start event. If the process does not contain any explicit start events, the process starts by using an implicit start event.
