An expert system generating explanation for fault diagnosis in a water rig system

A project is underway to construct an IKBS for fault diagnosis in a process control system able to cope with both single and multiple faults, and which generate explanation describing the reasoning underlying a particular diagnosis. The diagnosis system here uses qualitative modelling and deep knowledge techniques in which a behavioural and structural model based on the physics of a system, is formulated instead of using the classical shallow knowledge paradigm (using rules for example). So given knowledge of the input to a device and an understanding of how it is supposed to work, then expectation about its actual behaviour can be generated. Then a comparison between these two, specially the difference between them, provides the foundation of the trouble-shooter.<
