面向对象知识表示方法在摩托车设计中的应用

知识表示是建立设计专家系统的关键技术之一.针对摩托车整车总体设计的要求,研究摩托车设计的知识和经验的分类,分析了产生式规则、框架和面向对象等知识表示方法的特点,结合面向对象方法的抽象性、封装性、继承性等特性.提出了以面向对象为主、产生式规则为辅的知识表达方法,并采用面向对象封装产生式规则的方法,在C 程序语言环境下实现摩托车设计知识的表示,同时给出托车车架计的知识表示实例.

Application of Object-oriented Representation in the Motorcycle Designed Expert System

Knowledge representation is one of the key technologies in the designed expert system.According to the requirement of total design of motorcycle, this paper researches the classificationof knowledgeand experienceof the motorcycle, analyses the points of knowledge representationmethod such as production rule, frameworkand object-oriented and so on, and puts forward the object-oriented knowledge representation method which is combined with abstraction, encapsulationand inheritanceof object-oriented technique. At last the authors realizes the knowledge representation of motorcycle designing under the language environmentof C++ and givesthe knowledge representationexamples of motorcyclebodywork designing.
