Towards Model Validation and Verification with SAT Techniques

pdf-format:


Abstract

After sketching how system development and the UML (Unified Modeling Language) and the OCL (Object Constraint Language) are related, validation and verification with the tool USE (UML-based Specification Environment) is demonstrated. As a more efficient alternative for verification tasks, two approaches using SAT-based techniques are put forward: First, a direct encoding of UML and OCL with Boolean variables and propositional formulas, and second, an encoding employing an intermediate, higher-level language (KODKOD, stongly connected to ALLOY). A number of further, presently not realized verification and validation tasks and the transformation of higher-level modeling concepts into simple UML/OCL models, which are checkable with SAT-based techniques, are shortly discussed. Finally, the potential of SAT-based techniques for model development is again emphasized.
