Abstract : Most of the diagnostic systems that have been developed in medicine as well as other domains can properly be called compiled knowledge systems in the sense that the knowledge base contains the relationships between symptoms and malfunction hypotheses in some form. However, often in human reasoning, an expert's knowledge of how the device functions is used to generate new relationships during the reasoning process. This deeper level representation which can be processed to yield more compiled diagnostic structures is the concern of this paper. Using the example of an household buzzer, this paper shows what a functional representation of a device looks like. It also indicates the nature of the compilation process that can produce the diagnostic expert from this deeper representation.
