Abstraction-enriched Formal Methods Integration

The paper presents the results of our research in the field of combining process algebra and Petri nets. To provide better support for design and analysis of larger-scale systems by means of abstraction mechanism, the method itself and the tools allowing its practical application have been enhanced significantly. The theoretical aspects and implementation of enhancements are discussed in detail. Careful testing, along with the process of implementing the new functionality into one of the involved tools, helped us to disclose its certain hidden imperfections, which are subsequently addressed.
