Applications of expert systems in manufacturing: A case study

This paper describes the practical experience gained in a project the aim of which was to introduce expert system technology into a manufacturing organisation. The project involved the development of an expert system shell and a knowledge base for fault diagnosis in numerically controlled machine tools. Particular emphasis is placed on the implementation strategy and the difficulties encountered during the course of the project. Factors discussed include management support and availability of technical expertise. Current limitations of expert system technology with respect to engineering applications are also discussed.

An experimental transformation of a large expert knowledge base

An experiment is described in which a significant part of the INTERNIST knowledge base for diagnosis in internal medicine is translated into an EXPERT model. INTERNIST employs the largest and broadest knowledge base of all the medical consultation systems that have been developed in recent years. EXPERT is a general system for designing consultation models. The translated model shows reasonable competence in the final diagnostic classification of 431 test cases. There are differences in the internal representation and reasoning relatively uniform manner, this experiment demonstrates the feasibility of transfer of knowledge between large-scale expert systems.
