Design Adaptation Using Case-Based Reasoning |
| Abstract |
This research deals with two important issues in Case-Based Design(CBD): a structure of design cases and a process of design adaptation for handling design failures which is crucial especially in Case-Based Design. This paper proposes the structure of design cases consists of problem situation, design specification, design tasks, design solutions, causal explanation, and past design failures as well as design performance. It has been noticed that how to represent a structure of design cases and how it can be used in an actual process of design adaptation process are critical in Case-Based Design paradigm. Also, it suggests an integrative system architecture for design adaptation as well as a model of adaptation process. This paper characterizes various types of design failures for choosing a direction of failure resolution based on causal explanation. Figuring out the strategic approaches of design adaptation process in a analytical way is the major focus of this research adopting Case-Based Design paradigm. A model of causal explanation is presented as a useful tool for identifying sources of design failures. Applicability of the suggested adaptation process is demonstrated in an exemplary kitchen layout task. |
