【摘要】 CAD 的关键是计算机自动化设计,实现设计自动化的途径有二种:(1)开发自动优化技术用于辅助设计,(2)开发人工智能技术作为计算机辅助设计与／或决策系统。本文阐述了我们的研究过程中的成果。从1984年起作者们开始进行预应力混凝土梁自动优化设计的研究。研制的“SBAODS”系统发表于1986年,并在实践中成功地被应用。在此期间,作者们又开始研制其他桥式结构的自动优化设计程序:连续梁·斜(?) 刚构桥和拱桥等。在上述成果基础上现正将基于知识的智能化引人 CAD 中。更多还原

【Abstract】 The mian point of CAD is in providing a way to automate the computer design.Automation of desion may take two paths.(1)development of the automated optimum techniques to aid designig;(2)development of the artificial intelligent techniques as a means in the computer-aided design and/or decision system. This paper outlines the work of the progress in our research.Since 1984 the authors started research work of the automated optimum design of prestressed concrete beam.The program system“SBAODS”was published in 1986 and has been successfully used in practice. Meanwhile the authors have started develope the programs for automated optimum design of other types of bridges:continuous beam;strut-frames and arch-type bridge. Based on the experience in above-mentioned works,the knowledge-based intelligence is being introduced into CAD.更多还原
