Fault Diagnosis
Part of the Lecture Notes in Computer Science book series (LNCS, volume 604)


This paper describes the SIMEX (Simulation based Expert System Tool) system, which performs fault localization by exploiting the causal and behavioral information contained in simulation models for the generation and verification of fault hypotheses. The system has been developed for space applications in order to improve ground based mission control. It is, however, also applicable for process monitoring purposes. The overall system concept, required model information and the hypotheses generation strategy will be outlined. A sample application will be briefly described. Project status and related research will be sketched.
