Modeling and analysis of complex computer systems-the MTCCS approach

The paper presents results from work in progress on finding a method for formal specification and verification of real time concurrent systems that incorporate a non trivial data component. We have extended Timed CCS, a timed CCS variant with a model oriented data language based on VDM. The semantics of the extension, called MTCCS is expressed in a combination of denotational and operational style. We show how verification of temporal logic properties based on symbolic model checking can be made possible for such a combination notation.
