There is an emphasis on representation of knowledge and principles of good design of KBS to be implemented using commercial shells. Topics include knowledge-based systems and expert knowledge, knowledge representation using production rules and frames, classifications of problem domains including diagnosis, synthesis, help desk, analysis techniques for knowledge bases including influence diagrams. Recent developments in knowledge-based links to data sources and external programs and the characteristics of `second generation' expert systems will be explored. KBS development methods and the management of knowledge-based systems projects will be discussed including planning and control; roles of the sponsor, user, knowledge engineer, expert; the relationship of the knowledge-engineering group to the data processing department; and project evolution and maintenance. A major component of the subject will be to learn and use a knowledge-based development tool.
