Proposal and evaluation of a KBE‐RM selection system

Purpose – The purpose of this paper is to propose and evaluate a novel tool for the assessment and selection of rapid prototyping (RP)/manufacturing (RM) systems as alternative processes for low‐volume production in the machinery and equipment design sector. By analysing previous RP/RM selectors, this research addresses the necessary factors that a knowledge‐based engineering (KBE) system must include for the analysis, comparison and ranking of candidate technologies.Design/methodology/approach – This research starts with the analysis of previous KBE solutions for RP/RM process selection, then a new KBE tool is proposed through the integration of artificial intelligence tools such as fuzzy logic, artificial neural networks (ANNs) and relational databases. Three case studies, provided by a Spanish machinery design centre, are used in order to measure the suitability of the proposed system for the assessment of real designs of special purpose mechanical parts.Findings – The paper reports several improvement...
