案例式推理是電腦輔助設計中新的研究領域。本文為建築設計中的案例式設計與 推理系列研究，主要電腦運算之觀點探討如何建構案例式推理系統。以先前關於設計者如何 進行案例式設計與案例調適等設計行為的研究與設計實驗發現作為基礎，探討案例式推理系 統之元素，包括案例表示法、案例索引與組織、案例調適方法、與介面。本研究以小學校園 配置來說明案例式推理系統之建構，同時檢驗相似性評估與搜尋機制。本研究從建構案例式 推理系統分析中提出未來研究與發展方向之建議。

　　　　　Case-based reasoning is a new research paradigm in computer-aided design. This paper depicts the studies of case-based design and reasoning in architectural design from the computational view. Based on previous study, this study explores the elements of case-based resoning system, such as case representations, case indexes and organziations, adaptation methods, system interfaces and functions. This study also implements a case-based reasoning system of campus layout for elementary schools, and examines the case similarity assessment and searching mechanisms. In conclusion, this study provides the basic understandings from the exploration of establishment of case-based reasoning systems, and implications for future development.
