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)系统的支持。大多数设计活动都要满足至少一个设计标准。CAE系统通常是通过将标准的规定解释和改造成赋值语句，然后将它们硬编码到系统中来开发的。这种制度缺乏灵活性(仅适用于一种标准)，经常因标准的变化而失效，并容易出现误解错误。相反，如果以声明的方式表示标准，然后提交给CAE系统进行操作(使用基于知识的标准处理系统提供的工具)，将减少失效和误解。设计系统也将更加灵活，因为它可以通过向系统提供该标准的表述而使其对另一设计标准有效。这位首席研究员在之前的研究中开发了这样一个标准处理器的原型。这个原型证明了标准可以从它们的使用中分离出来，但它仍然需要更多的研究和开发才能用于计算机辅助工程系统的开发。本研究的目标是将设计标准的陈述性表示完全重塑为面向对象的模型，并对基于知识的标准处理器进行扩展和修改，以解决原型中的不足。

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.
