【摘要】 从基于事例推理技术理论出发．在Ｎａｖｉｎｃｈａｎｄｒａ、Ｂａｒｄａｓｚ、ＺｅｉｄＩ等学者提出的设计事例表示方法基础上提出更为通用、有效的设计事例表示形式，即设计事例３级表示方法和它的组织结构，并结合火炮总体设计的具体特点，给出火炮总体设计事例表示形式定义、组织及推理策略，以及火炮设计专家系统模型。通过研究表明，采用事例形式的知识表示可以有效地利用火炮设计经验，提高火炮设计质量、缩短设计周期，有力地推进人工智能技术在火炮设计领城中的应用。更多还原

【Abstract】 This paper, using the case-based reasoning techniques, provides a very general and effective method and its organization ofdesign-case representation on basis of the methods of design-case representation provided by Navinchandra, Bardasz and Zeid I. It is themethod that design-case is represented by three levels: concept case, process case and element case. The paper also provides the definition ofdesign-case fopresentation, organization. retrieval method and the model of artillery design expert system for artillery general design. Itillustrates that the method can effectively represent raillery design experience, enhance the quality of design, make the design period shorten,be poweffully applied in altillery design.更多还原
