cmUML - A Precise UML for Abstract Specification of Concurrent Components

Publication Type:

Conference/Workshop Paper


Parallel and Distributed Computing and Systems




Unified Modeling Language (UML) has become a de facto industry standard graphical language for design specification of object oriented systems. But, due to lack of formal semantics UML models are not suitable for rigorous formal analysis. This paper defines a UML subset language (cmUML) with formal semantics for precise and abstract specification of concurrent components independent of implementation issues. The approach provides modular specification and verification of larger systems. An integrated multi-view operational semantics of cmUML is defined using symbolic transition systems. This highly expressive language provides constructs to specify explicit parallelism, conditional synchronization, mutual exclusion, safety, and liveness notions as well as the behavior of the interacting environment.
