摘要
图形表达是当前工程设计领域存在的重要的设计形式。在综合分析了目前建造专家系统的主要 4种常用开发环境的基础上 ,提出了一个以数据库和专家系统相结合的图形评价系统解决方案。该方案将图形评价知识以关系数据库的形式予以表示 ,评价算法则采用专家系统的推理机方法 ,实现了评价问题的多种算法。在分析了目前流行的数据库前台开发工具PowerBuilder开发专家系统的优越性的基础上 ,用PowerBuilder设计并实现了一套计算机图形评价专家系统框架。应用表明 ,该系统有较强的实用性。
Engineering drawing is a main format of engineering design. Based on the studies of several developing platforms for constructing the expert system (ES) , a scheme for computer drawing evaluation system based on ES and database technology are presented in this paper, in which the evaluation criteria are presented by database tables and several evaluating arithmetic programs have been proposed based on ES principles. Finally, a general frame of computer aided evaluation system (CAES) has been designed and realized with PowerBuilder which has several advantages on developing the expert system. The system is proved to be feasible through applications.
