Conceptual design has been paid increasing attention by academia and industry. However, there is no consensus of the concept of ‘func- tion’ in the domain of conceptual design, making automated func- tional decomposition a difficult problem. The goal of this study is to develop an automated functional decomposition method based on the formal representation to model the morphological changes of material flows. Hierarchical material structure representation and a hierarchical shape graph are used to abstract the morphologi- cal properties of a material. Based on the semantics contained in the input and output material flows, together with decomposition principles, an overall function is broken into several sub-functions.
Moreover, a sequence-planning algorithm of sub-functions is pro- vided to facilitate achieving all of the morphological changes of a material flow. Finally, the proposed method is implemented, and some analyses are provided
