The Development of Conceptual Design System of Structures by Knowldge Engineering Technology

传统上，设计概念化是基于经验和直觉来进行的，因为这样的组合过程被认为不适合机械化。然而，知识工程的显著发展使计算机在这一领域的应用变得明朗起来，结构设计概念化的基本问题是形状确定，它的目的是利用经验知识和力学规律建立结构的初始概念。这种思想分别等同于人工智能中的表层知识和深层知识，并可象知识处理的进化一样在计算机上实现。在本研究中，开发了框架结构设计专家系统的原型（Mark Ⅰ和Mark Ⅱ）。该系统通过交互式地提供数据和知识，使设计者能够构建框架的概念。在此基础上，开发了材料硬度计算机辅助学习系统和仿形机故障诊断系统。并对形状判定算法在复杂系统中的应用进行了初步尝试。

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.
