Engineering design processes are highly creative and knowledge-intensive tasks that involve extensive information exchange and communication among diverse developers. In such dynamic settings, traditional information management systems fail to provide adequate support due to their inflexible data structures and hard-wired usage procedures, as well as their… (More)
Motivated by a chemical process engineering application, we introduce a new concept constructor in Description Logics (DLs), an n-ary variant of the existential restriction constructor, which generalizes both the usual existential restrictions and so-called qualified number restrictions. We show that the new constructor can be expressed in ALCQ, the… (More)
Documenting the rationale in design processes is commonly accepted to be rewarding, but rarely done in practice due to the required time and effort. We propose an integrated approach to work process and decision modeling, characterized by both an improved usefulness of the models and less effort for their creation.
