Symbolic model checking is PSPACE complete. Since QBF is the standard PSPACE complete problem, it is most natural to encode symbolic model checking problems as QBF formulas and th...
In this paper a novel approach for the tool–based quality assurance of models is presented. The approach provides a meta model framework for domain specific and tool–independe...
Qualitative Reasoning is characterised by making knowledge explicit in order to arrive at efficient reasoning techniques. It contrasts with often intractable quantitative models. W...
We present a case study that aims at quantitative assessment of the impact of requirements changes, and quantitative estimation of costs of the development activities that must be ...
The model checking of applications of aspects is explained, by showing the stages and proof obligations when a collection of generic aspects (called a superimposition) is combined...
