| Abstract: | The kernel architecture for a diagnostic expert system is proposed. The elementary contents are a hierarchical and partitioned-knowledge base and a blackboard. The hierarchy of the system is described: the system can be divided into two levels, a meta-level system, the task of which is to implement some concrete diagnoses. The hierarchy and partition of the object-level knowledge base are described; the base can be further divided into two levels,a system-level, which is subdivided into several knowledge sources according to the type of fault and a subsystem-level, which is subdivided into several knowledge sources according to the functional subsystems. The goal-oriented strategy used in the system as a macro-control strategy and "blackboard" used in the system as a comprehensive working memory are explained. |
