An `AI in Design' View of Design
System Knowledge

Domain Knowledge Entities

Describe the domain knowledge entities used by the system.

e.g., component attributes, parameter dependencies, constraints on component connectivity, physical laws, etc.

Discussion. Each of the general categories of domain-dependent knowledge is represented by specific entities, depending on the particular domain and the type of problem which is being solved. For example, systems which develop new designs will need various kind of information about the components and about how they fit together [Brown 1997] [Wielinga & Schreiber 1997]. If redesign is the central issue then parameter dependencies are important, since they will show the impact of changes on the rest of the system [Orelup et al. 1988] [Ramachandran et al. 1988].
