SOFTWARE FOR SUPERVISION SYSTEM DESIGN IN PROCESS ENGINEERING INDUSTRY

Abstract The software “ModBuild” presented in thid paper is developped for process monitoring applications. It automatically creates complex process dynamic models from a simple graphical interface, where system components can be dragged from a component data base and interconnected so as to produce the overall system, following the Piping and Instrumentation Diagram. Once the model has been created, ModBuild checks its consistency and performs its structural analysis in order to automatically determine the diagnosis algorithms which should be implemented, and their fault detectability and isolability performances. The friendly graphical user interface allows to test several sensor configurations in order to optimise the diagnostic possibilities. The obtained model can also be used for the simulation of the process and its diagnosis algorithms in normal and faulty situations.
