Zusammenfassung

The QuantUM modeling framework and analysis tool, which allows for the analysis of quantitative aspects of system architectures modeled in UML / SysML, does not o er an adequate treatment of nondeterminism. We present an extension of the QuantUM approach based on an interpretation of QuantUM models as Markov Decision processes so that non-determinism in these models is semantically interpreted in an appropriate way. We show that the formal semantic interpretation of the UML / SysML models that we propose coincides with the code generation semantics for a widely used UML / SysML CASE tool. We evaluate the proposed approach by applying it to two industrial strength case studies, an Airport Surveillance Radar system and an Airbag Control Unit.
