Research Initiation: Object-Oriented Representation and Knowledge-Based Processing of Design Standards for Design

设计的各个方面越来越受到 计算机辅助工程（CAE）系统。 大多数设计活动 须符合至少一项设计标准。 CAE系统通常是通过解释和 将标准的规定改为任务说明 然后硬编码到系统里 这种系统 不灵活（仅对一个标准有效），经常无效 标准的变化，并受到误解 错误. 相反，如果标准是声明性地表示的， 然后呈现给CAE系统进行操纵（使用 由基于知识的标准处理系统提供的工具）， 无效和误解的情况将会减少。 设计 系统也将更加灵活，因为它可以使 通过为系统提供 这个标准的代表性。 这样一个原型 标准处理器是在以前的研究中开发的， 首席调查员 这个原型证明了标准 可以从它们的使用中分离出来，但它仍然需要很多 更多的研究和开发可用于计算机辅助 工程系统开发。 这项研究的目的是彻底重塑 设计标准的声明性表示， 面向对象的模型，并扩展和修改知识- 的标准处理器，以解决 样机

The aspects of design are increasingly being supported by computer-aided engineering (CAE) systems. Most design activity is subject to the satisfaction of at least one design standard. CAE systems are most commonly developed by interpreting and reforming the provisions of standard into assignment statements and then hard-coding them into the system. Such systems are inflexible (valid for one standard only), frequently invalidated by changes in the standard, and subject to misinterpretation errors. If, instead, the standard is declaratively represented, and then presented to the CAE system to be manipulated (using tools provided by a knowledge-based standards processing system), invalidation and misinterpretation would be lessened. The design system would also be more flexible, in that it could be made valid for another design standard by supplying the system with the representation of that standard. A prototype of such a standards processor was developed in previous research by this principal investigator. This prototype proved that standards could be separated from their usage, but it still requires much more research and development to be usable in computer-aided engineering system development. The objectives of this research are to completely recast the declarative representation of design standards as an object-oriented model, and to expand and modify the knowledge- based standards processor to address insufficiencies in the prototype.
