Abstract

Design knowledge representation has been regarded as a key aspect in design processes, especially at the early stage of conceptual design as it establishes the basis for the subsequent design activities. This paper presents a systematic knowledge representation model called Requirement-Function-Principle solution-Structure (RFPS), in which functional knowledge model (FKM) is proposed to represent the mapping relationships between the function layer and structure layer and to strengthen the design knowledge reuse in conceptual design. By investigating the mapping process, a transformation matrix (TM) is developed to reveal the mapping relations between the function representations and structure parameters and to identify whether the decomposition of the function layer reaches the lowest level. Then design structure matrix (DSM) is introduced to combine with RFPS to enhance the representation of the internal interactions of the function layer and structure component. A matrix transformation algorithm is put forward to facilitate the conversion procedure between TM and DSM. Finally, a case study is presented to demonstrate the proposed approach.
