Computer programs have been developed which embody knowledge distilled from experts in a given area and which, when given suitable data, reach the same conclusions as would human experts. Such programs are called expert systems and have been constructed for a number of purposes including medical diagnosis and mineral exploration. Hushon (i) has assembled information about expert systems for environmental problems, and Waterman (2) discusses the principles and construction of expert systems and describes systems used in a number of fields. 

Dr. Marlene Jones is a senior researcher in Artificial Intelligence in the Alberta Research Council s Department of Advanced Technologies and an adjunct professor in the Department of Computational Science at the University of Saskatchewan. Prior to joining the Alberta Research Council in January 1987, Dr. Jones was a tenured Associate Professor at the University of Waterloo. Her qualifications include a PhD (Computer Science) from the University of Toronto and an MEd (location of Exceptional Children) from the University of Saskatchewan. Her research experience expands mote than a decade, with the last 8 years focussed upon research in the area of AI and Education. Dr Jones recent research projects include the development of expert systems for educational diagnosis, expert environments for curriculum and course development, and user modelling.

One would also like to compare the diagnoses with the actual transformer condition, and not Just with the expert s previous assessment of the condition. Unfortunately, this is usually not possible, it is expensive to remove a transformer from service, open it up, and determine its condition. However, this was done for ten of the 208 "problem" cases. Engineers overhauled these transformers and determined the nature and cause of their problems. For all ten of these cases, both the expert system and the expert had made the correct diagnosis. 

An expert process operator, once alerted, will focus attention on the problem. This may involve invoking procedure rules for safety or other reasons, and it may involve assembling information and primary analyses to allow inference about the problem. Logic rules and procedures are used when required for the diagnostic inference. The expert system mimics the expert process operator in this regard Logic rules and procedures are invoked specifically when they are required for diagnosis of a process problem, or as requested for a specific step in inference. 

An expert system is a computer program to reproduce a problem-solving manner according to an expert s knowledge and inference procedures in a computer system. Expert systems have been used for fault diagnosis in bioprocess operations, the improvement of medium composition, and the optimization of culture conditions, since it can handle a large amount of information and data concerning bioprocess operation and optimization [13]. 

Good models are needed for the design and operation of combustion systems. Expert systems, might, for example, contribute to diagnosis of operating problems or aid in the design of more complex systems.
