Abstract

This paper demonstrates the use of an established integrated method (that is Hazard and Operability Studies, Ward and Mellor Essential Models and the Synchronous Calculus of Communicating Systems) to model and analyse control systems. In particular, we discuss the interplay between traditional hazard analysis techniques and formal methods and their associated analyses in the context of an integrated model. Also a process model with tool supports is proposed for developing of a safety-critical software for real-time control systems. Our approach is illustrated by a small but realistic industrial case study.
