基于知识库的焊接工艺设计专家系统

从焊接工艺设计的特点出发，按照焊接工艺知识的复杂性和多样性，以不同的知识表示方式为基础开发焊接工艺设计专家系统。通过对焊接工艺知识的归纳总结，系统将焊接工艺知识按其特点分为5类，并针对不同类知识分剐以不同的知识表示方式来表示；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。系统可视化的图形用户界面极大地方便了用户对知识库的各项操作和维护。

A knowledge-based expert system for welding technique design

According to the feature of welding technique design, an expert system of welding technique design is developed based on different knowledge expression styles,in terms of the complexity and diversity of welding technique knowledge.The system classifies five types of welding procedure knowledge by their traits,and expresses the knowledge in different styles.In the light of expert system design theory and the data which user has inputted,the system can search and make welding procedure documentations automatically based on the blindness search strategy and unusual precedence strategy.The graphical user interface makes users manipulate and maintain knowledge base very conveniently.
