BEHAVIOR Abschlussbericht der Anwender

Model-based diagnosis systems - as known in the beginning of behavior - have been more or less in an experimental state or were designed for special purposes only. In BEHAVIOR, universal software modules for model-based fault detection had to be developed and tested by STN for a relevant domain. A ballast tank system for off-shore plants was taken as application which shows all relevant aspects like non-linear dynamic behaviour, sufficient complexity and multiple faults. First, quantitative models for normal and faulty behaviour of the system were described. These models were used for a simulation which was built up by software components and integrated into the BEHAVIOR workbench. Finally, two BEHAVIOR diagnosis systems (MUDIA, GDE+) were tested in this simulation context. The results of this evaluation show that both systems are able to detect and to discriminate faulty behavior of components in a dynamic, non-linear system. The developed modules could be used for monitoring systems and diagnosis extensions to improve the safety and to support the crew. Furthermore, possible applications are the predictive simulation of system behaviour, the off-line fault analysis and the support of the system design by modelling and simulation of the plant.
