Validation of UML Models Thanks to Z and Lustre

摘要

Graphical notations such as UML are very popular thanks to their simplicity and their intuitive aspect. Nevertheless their lack of precise semantics limits the possibility of the specification validation. So we propose here to translate some of the UML models into Z and Lustre formal specifications in order to use a theorem prover and a test generator to validate the models. This approach is presented on the "cash-point" service case study proposed during the world Formal Method congress 1999 tool contest.
