This article aims at building a computable design process model
which is a prerequisite for realizing intelligent CAD systems. First, we
discuss design processes seen from a theoretical point of view, i.e. 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 to describe the evolutionary nature of design. Second, we
examine design processes from a cognitive viewpoint. We show a cognitive
design process model obtained by observing design processes using a protocol
analysis method. Then, we discuss a computable model that can explain most
parts of the cognitive model and that also can interpret the descriptive
model. In the computable model, a design process is regarded as an iterative
logical process realized by abduction, deduction, and circumscription. We
implemented a design simulator that can trace design processes in which
design specifications and design solutions are progressively revised as the
design proceeds.
