A Solution to the TTC'15 Model Execution Case Using the GEMOC Studio

Description

We present in this paper a complete solution to the Model Execution case of the Transformation Tool Contest 2015 using the GEMOC Studio. The solution proposes an implementation of the most complete version (variant 3) of the UML Activity Diagram language. The implementation uses different technologies integrated into the GEMOC Studio for implementing the various concerns of the language: Kermeta is used to modularly implement the operational semantics and to weave it into the provided metamodel, Melange is used to build the overall language runtime seamlessly integrated to EMF, Sirius Animator is used to develop a graphical animator, the GEMOC execution engine is used to execute the conforming models according to the operational semantics and to build a rich and efficient execution trace that can be manipulated through a powerful timeline, which provides common facilities like, for instance trace visualization, and step-by-step execution (incl., breakpoint, step forward and step backward). Finally, MoCCML is used to provide an alternative to the implementation with an explicit and formal concurrency model for activity diagrams supported by a solver and analysis tools. We evaluate our implementation with regard to the evaluation criteria provided into the case description and provide evidence of the correctness, understandability, conciseness and performance of our solution.
