An Integration Scheme for CPN and Process Algebra Applied to a Manufacturing Industry Case

A semiformal development method for obtaining a correct design of embedded control and real-time systems is presented. The design is obtained from a Colored Petri Net (CPN) model of a real-time system, which is subsequently transformed into a formal system specification using CSP+T process algebra. The method translates CPN modelling entities into abstract processes, which allow the expression of concurrency and real-time constraints. The correct design of a “key“ component (feed belt controller) of a paradigmatic manufacturing problem (the Production Cell) is discussed as to show the applicability of our method.
