压铸模CAD中知识库的设计与建立的研究

摘要

KBE技术关键是设计中体现知识获取、知识表示、知识推理和知识管理.基于KBE的开发,本系统使用Visual C++语言,以面向对象的技术为指导建立知识库,采用对象的概念表示问题域中的实体,规则的具体内容则分布在相关对象的属性和方法中,从而充分地发挥了信息隐蔽、继承和多态等面向对象的特点.%KBE technology is based on knowledge extraction, knowledge representation, knowledge inference and knowledge control in the design. This system uses Visual C++ lan guage; take the object-oriented technology as the instruction establishment knowledge li brary; use the object in the concept representation question domain entity, the regular spe cific content then distributes in the correlation object attribute and the method, thus many object-oriented characteristic such as information hiding and knowledge inheriting with many conditions are fully displayed.
