An `AI in Design' View of Design

Are there any hierarchies provided?

Discussion. As design is often approached as a decomposition problem, hierarchies are often used for guiding the decomposition process. Some hierarchies encode abstraction levels, while others represent part-of relationships. Various degrees of abstractness in a hierarchy of functions can be helpful in function instantiation, while a hierarchy of components can be used for structural decomposition tasks [Lee et al. 1992] [Umeda & Tomiyama 1997].
