摘要

This article aims at building a computable design process model which is a prerequisite tor 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.
