Application of UML in plant modeling for model-based verification: UML translation to TNCES

There do exist dozens of formal languages and formalisms that may be used for modeling different phenomena of real world. The time for industrial acceptance of a certain language is directly proportional to the complexity of the language. In our work we apply timed net condition/event systems (TNCES) formalism for modeling a closed loop system depicting interconnected controller and controlled plant. We hope to increase the method adoption by applying a Unified Modeling Language (UML) for plant modeling. UML is well-developed language supported by a number of tools. This paper gives general details on the approach to the formal validation and verification of industrial systems and presents the translation procedure of UML to TNCES.
