工程智能化CAD系统设计

THE DEVELOPING OF INTELLIGENT CAD SYSTEM FOR ENGINEERING DESIGN

本文通过对工程设计过程及其特性的讨论，提出了工程设计过程的理论模型规划控制下的二阶段设计模型，论述了基于这一模型的工程智能ＣＡＤ系统设计方法及其关键技术：工程数据库和知识库技术。并将这一方法成功地应用于桥梁工程智能ＣＡＤ系统的开发实践。

A design model on two-stage under the planning control is presented by the study of artificial intelligence, behavior and characteristics of engineering design. With this model, the theory of developing intelligent CAD system is discussed. The key technology for engineering database and knowledge database is also studied. By the application of this model and theory, several ICAD systems for bridge engineering have been developed.
