面向对象技术在焊接工艺设计专家系统中的应用

将面向对象技术用于焊接工艺设计专家系统的开发。该系统应用专家系统的设计原理，根据用户输入的已知事实，采用盲目搜索、特殊优先等交替使用的搜索策略，自动搜索和生成焊接工艺文件；系统可视化的界面极大地方便了用户对知识库的各项操作和维护。该系统采用面向对象的可视化编程语言——Visual Basic6．0作为开发工具，并通过Access数据库建立焊接事实数据库，全面而完整地描述系统的信息。

APPLICATION OF OBJECT- ORIENTED TECHNOLOGY IN THE WELDING PROCEDURE DESIGN EXPERT SYSTEM

Object-oriented technology is applied in welding procedure design expert system in this article. According to the design principal of the expert system and the data which users have inputted, the system looks for and generates welding procedure documentations automatically based on the blindness search strategy and unusual priority strategy. The graphical interface makes users manipulate and maintain knowledge base very conveniently. The objected-oriented visual program language - Visual Basic6.0 and Access database are applied in the system to describe the welding procedure information.
