Engineering Design is a knowledge intensive process, including conceptual design, detailed design, engineering analysis, assembly design, process design, and performance evaluation. Each of these tasks involves various aspects of knowledge and experience. Whether this knowledge and experience can be effectively shared is a key factor for increasing product development capability and quality, and also for reducing development cycle time and cost. Consequently, offering engineering designers various query models for retrieving engineering knowledge is one of the most important tasks in engineering knowledge management. Meanwhile, the query models for retrieving engineering knowledge include customer requirement-based knowledge retrieval, functional requirement-based knowledge retrieval, functional feature-based knowledge retrieval, and engineering specification-based knowledge retrieval. 　The objective of the research is to develop a technology for functional feature and engineering specification-based reference design retrieval, based on an integrated clustering approach to facilitate engineering designer with easy access to relevant design and other knowledge based on the descriptions of functional features, feature relationships, and engineering specifications. 　The results of this study will enable product information and engineering knowledge sharing in engineering design and subsequently reduce development cycle time and ultimately increase design efficiency.
