SIMULATION

Our Senior Managers were dead serious. The project schedule was backed against the start of summer brewing. Molson Breweries in Barrie, Onta rio, Canada replaced an obsolete control system and instrumentation wi ring with a state of the art PLC/DMAC's control system. The project te am faced the normal constraint of a fixed budget; the challenge was th at wiring conversion and start-up had to completed within four weeks.T his paper details one of the factors, simulation, contributing to this project's overwhelming success; some of the others included an integr ated project team, an innovative schedule and the use of an integrated set of real-time dynamic modelling tools, and their subsequent use in exercising and testing the DMACS operator interface, P.L.C. logic, ne w operating procedures and extensive operator and technician training. Conversion took three weeks and the Brewhouse achieved full productio n in its first week of operation.
