Abstract.
Complex computing systems exhibit various behavioural aspects, for example communication between components, state transformation inside components, and real-time constraints on the communications and state changes. Formal specification techniques for such systems have to be able to describe all these aspects.

Unfortunately, a single specification technique that is well suited for all these aspects is not available. Instead one finds various specialised techniques that are very good at describing individual aspects of system behaviour. This observation has led to research into the combination and semantic integration of specification techniques.

In this talk we present a combination of specification techniques for processes, data and time: CSP, Object-Z and Duration Calculus. The emphasis is on a smooth integration of the underlying semantic models. Also some ideas on verifying properties of such combined specifications are discussed.
