This article discusses building a computable design process model,
which is a prerequisite for realizing intelligent computer-aided design
systems. First, we introduce general design theory, from which a descriptive
model of design processes is derived. In this model, the concept of
metamodels plays a crucial role in describing the evolutionary nature of
design. Second, we show a cognitive design process model obtained by
observing design processes using a protocol analysis method. We then discuss
a computable model that can explain most parts of the cognitive model and
also interpret the descriptive model. In the computable model, a design
process is regarded as an iterative logical process realized by abduction,
deduction, and circum- scription. We implemented a design simulator that can
trace design processes in which design specifications and design solutions
are gradually revised as the design proceeds.
