The development of an interactive fault diagnosis expert system for telecommunication applications
This paper presents work on an interactive fault diagnosis expert system for telecommunication applications. A new knowledge representation and inference algorithm is proposed to suit the characteristics of the application environment, namely: (1) no parallel event exists in human fault reporting, (2) the diagnostic sequence is unpredictable, and (3) the inference engine is passive in an event-driven environment. A lattice data structure is used for knowledge representation, which is generated automatically from a script of decision rules. The inference engine works in a transaction-like style by prompting and responding to the user according to the knowledge in the lattice. It can explicitly guide the inference sequence, as well as respond to ad hoc input from the user.
