Utilizing multilevel models and reasoning for diagnosis of a complex electro-mechanical system
John A. Smith, Gautam Biswas · 1989
A multi-level system which utilizes both an evidential and a qualitative model for diagnosing fault symptoms in complex electro-mechanical systems is presented. The operation of both models, enhancement by a historical database, and the global control strategy are all discussed. In addition, the constraining of qualitative reasoning with information from the evidential session and the enhancement of the evidential model with information from the qualitative model is demonstrated.
