Formal Deadlock Elimination in an Object Oriented Conceptual Schema

Object oriented models model structural and behavioural aspects of objects in the Universe of Discourse. As the dynamic aspects of objects include parallelism and synchronisation of object life cycles, conceptual schemas must be verified for problematic behaviour like deadlock. In this paper we will present fragments of a method for object oriented analysis and the process algebra that allows to formally verify a conceptual schema build according to this method for deadlock behaviour.
