Major approaches to automatic fault diagnosis of industrial plants are
either subjective or objective. Subjective approaches imitate and syn
thesize the way that human experts diagnose faults. Objective approach
es automate a portion of diagnosis task that human's cognitive limitat
ion does not allow handling it efficiently. Currently available subjec
tive fault diagnosis techniques suffer from certain drawbacks such as:
lack of knowledge for modeling and reasoning with the required levels
of detail; inefficiency in utilization of sensory data; and poor in l
earning experienced schemas. A subjective approach to fault diagnosis,
using qualitative modeling and reasoning within the multiple view of
the system is introduced. The focus is on automation of the cognitive
skills of human experts, that include utilizing conceptual models to d
etect inherent redundancy in system behavior; qualitative reasoning to
predict future states; and information selection to avoid computation
overload.
