Specification of an automatic manufacturing system: A case study in using integrated formal methods

An automatic manufacturing system serves as a case study for the applicability of an integrated formal method to the specification of software systems. The formal method chosen is CSP-OZ, an integration of the state-oriented formalism Object-Z with the process algebra CSP. The practicability as well as limitations of CSP-OZ are studied. We furthermore employ a graphical notation (class diagrams) from the Unified Modelling Language to describe the architectural view of the system. The correctness of the obtained specification is checked by a translation into the input language of the CSP model checker FDR and a following property check.
