Correctness of UML class diagrams annotated with OCL constraints can be checked using
bounded verification techniques, eg, SAT or constraint programming (CP) solvers. Bounded …

Only four decades after the first manned flight to the moon, a common device such as a
smartphone consists of more complex technology than the “high-end” computers that …

The validation and verification of models becomes increasingly important as the complexity
and overall costs of later development stages increase. Although, a variety of tools exists for …

UML/OCL models are used to describe system models in early stages of the design process.
In order to detect design flaws in these models as soon as possible (ideally before the …

The Unified Modeling Language (UML) together with the Object Constraint Language (OCL)
are the description means for modeling and specifying, eg, software systems in early stages …

Utilizing all the methods introduced in the previous chapters allows for automatically
conducting various validation and verification tasks using the UML/OCL model of the system …

This chapter covers structural aspects of models, namely inconsistency and (in)
dependencies. In the first part of this chapter, contradictory UML/OCL models are analyzed …

In this chapter, we present a symbolic formulation representing all system states of a given
UML/OCL model. We thereby do not only consider the usually assumed 2-valued logic, but …
