An export system of supporting design thinking processes for the initial stage of architecture design

It is difficult to obtain the practical knowledge of design and convert it into rules for constructing a CAAD expert system. In order to support the design thinking processes at the initial stage, a CAAD expert system framework based on the Case-Based Reasoning(CBR) is proposed in this paper. The proposed system has following characteristics: 1)The CBR method which is suitable to the idea design is used in our system. 2)Not only the thinking informations, which include the design know-how such as the design drawings,intention and approachs, but also the used architecture code are abstracted as the contents of case. 3)CBR and Rule-Based Reasoning(RBR) are integrated into the inference mechanism to improve the inference ability of the system.
