Modeling Scenarios in Scenario-Based Multithreading for Real-Time Object-Oriented Modeling

The paper presents our scenario modeling framework in scenario-based multithreading for object- oriented real-time modeling. Our modeling toolset allows scenario modeling by transforming a given UML 2.0 model to a scenario model. Our toolset provides for extended notion of scenarios that supports (1) concatenated scenarios, (2) mutually non-concurrent scenarios, (3) ports or structured classes with multiple cardinality, (4) message buffering, and (5) dynamic structures. Scenario models are intermediate models acting as bridges to gradually lead to the desired implementation. Consequently, our scenario modeling framework not only helps designers to more easily understand the model but also enable the identification of a feasible task set in a systematic way.
