Computer-aided fault diagnosis in technical systems: An expert system for fault identification in the vacuum system of a mass spectrometer

We took a critical look on currently common methods for constructing expert systems and examined closely their applicability for computer-aided fault diagnosis. We deemed these methods not appropriate for this domain and presented our Knowledge Processing Facility KNOPF as an alternative. By means of KNOPF/MS, an expert system for computer-aided fault diagnosis in the vacuum system of a mass spectrometer implemented by using KNOPF, we demonstrated the applicability of our approach.
