Explication of design requirements through reflection on solutions

摘要

Practitioners involved in engineering design use different knowledge sources to tackle design problems. From the point of availability two types are distinguished - well-structured, explicit knowledge as opposed to tacit, implicit and experience-based knowledge. Each type plays a particular role in engineering design, and thus in knowledge-based design support systems (KBDSS). We look at the support systems for engineering design. The knowledge-centred view is emphasised in three facets describing the proposed approach: knowledge representation for design, design process control, and retrieval of relevant knowledge. Paper presents a generic model of engineering design based on a discussion on reflection and its place in design. The proposed framework and its implications are justified on a well-known design example.
