项目摘要

Traditionally, the design conceptualization has beren executed on the basis of experience and intuition because such the combinatorial process has been belived to be not amenable to the mechanmization. However, the remarkable developemtn to the knwoledge enginnering throws light on the utilization of the computer in theis area.Basically, the fundamentals of the conceputuatlization of the structural design are refrred the shape determination, which aims to create the initial concept of a structure by using both the knowledge from experience and the mechanical laws. This idea is equnivalent to the surface and the deep knowledgrs in atetificial intelligence, respectively and can be implemented in usch a computer as in the evnironment of knoledge processing.In this developental research, the prototypes of the design expert system concerning the framweork structure (Mark I and II) were developed. The system enables the designer to construct the conept of the framework by providing the data and the knowledge interactively. Aheas of theis system, the computer-aided learning system of sternght of material and the diagnosis system of the copying machine had been developed. Moreover, the application of the shape determination algorythm into the compiex system was attempted as a basi research.

传统上，设计概念化是在经验和直觉的基础上执行的，因为这种组合过程被认为是不适合机械化的。然而，知识工程的显著发展为计算机在这一领域的应用提供了启示。基本上，结构设计概念化的基础被称为形状确定，其目的是通过利用经验知识和力学规律来创建结构的初始概念。这个思想相当于人工智能中的表层知识和深层知识，可以在计算机中实现，就像在知识处理的环境中一样。在本开发研究中，开发了框架结构（Mark I和Mark II）设计专家系统的原型。该系统通过数据和知识的交互提供，使设计者能够构建框架的概念。在此基础上，开发了材料强度计算机辅助学习系统和复印机诊断系统。在此基础上，尝试了形状确定算法在复杂系统中的应用。
