摘　　要：介绍了一种基于场景模型和网格技术的知识获取方法.该方法通过专家分析典型和非典型的产品设计实例,采用场景结构分析、记录和存储领域专家进行设计的过程、解决问题的过程和动作,抽取其中的知识,并用仓库网格和属性表技术来获取专家的明确知识和隐含知识,取得了良好的效果.系统采用适合Internet的扩展标志语言(XML)及相关的DTD描述和存储场景,通过事件驱动整个设计过程.This paper introduced a knowledge acquisition method based on scenario model and repository grid technology. Through providing typical and special product design cases to expert, and recording the method used by the expert to describe and resolve problems, we use a structure named scenario to log and store the analyzed cases by the expert, meanwhile using the technology of repository grid and attribute ordering table (AOT) to acquire design knowledge. It is a good way to capture explicit and implicit knowledge. This system uses XML (eXtensible Markup Language) and DTD (Document Type Define) to describle and store scenario, and is eventdriven to the whole design process.
