Knowledge Elicitation For Material Design Expert System

Knowledge elicitation including collection, analysis, and representation of knowledge is the most important stage, but also the principal bottleneck in the development of knowledge based systems. Due to the difficulties faced in the knowledge elicitation process, development of knowledge based system for material design in steel making industry is a complex task. An attempt is made in this paper to present a novel approach to deal with knowledge elicitation for material design problems which involves codification scheme for the customer special requirements and a new approach to collect knowledge from the experts utilising paper models along with structured and unstructured interviews This paper centres around the human aspects and the practical experience gained while developing a knowledge based system for material design at BHP Steel is the basis for this paper.
