A Expert System for aid in material selection process

An Expert System for aid in material selection process is proposed, which in conjunction with TOPSIS(Technique for Order Preference by Similiarity to Ideal Situation) method[l] provides a very effective and efficient technique of material selection for a component. TOPSIS is a highly advanced optimization technique, which requires that user provides relative importance to different properties by the author[2], the relative importance rating were to be decided by the designers. There it was pointed out that the designers may not arrive at the same conclusion due to their different rating technique even though they use the same technique. In the proposed method, an expert system has been presented, which use a small tool called Ruleniaster[2][3], and OPSS(developed at IIT Delhi) that facilitates the development of particular consultant paradigms. In identifying the knowledge base which was to be included in the system, special care was taken so that different designers get uniform results by using the proposed system.
