Abstract
A system for determining fault causes, including automated determination of hypotheses in the context of a fault cause analysis and automated performance of hypotheses verification, has a data processing device connected to a data input and visualization device and to a data memory. The data processing device contains a processing unit for fault cause analysis, a first comparator, a second comparator and a hypothesis selector. The data memory contains a general fault model, a fault event list, an empirical database and a storage area to store a log of the current fault cause analysis. The data processing device, following the selection of a fault event from the displayed fault event list by a user, to display to the latter hypotheses suggested by the system, following the selection of hypotheses to be verified, to carry out hypotheses verification and, as the result, to log and display determined fault causes.
