Fundamental Research on the Knowledge Intensive Machine Design Support System

本研究旨在为基于知识密集型工程思想的机械设计支持系统的开发做基础性研究。知识密集型工程是一种灵活运用大量工程知识，包括编码和非编码知识，以创造更多附加值的新型工程。本研究解决了以下三个问题：(1)利用超文本技术和网络技术集成编码知识和非编码知识的基础研究；(2)处理产品全生命周期知识的基础研究，包括设计、生产、操作、维护、再利用和回收；(3)知识密集型机械设计支持系统及其原型的基础技术开发。该系统可以集成编码和非编码的知识，包括视觉信息。它可以记录、编辑和重用KIFF(知识密集型工程框架)系统的操作，该系统是我们团队为支持知识密集型工程活动而单独开发的。记录的设计文档以Html格式生成，系统运行在ParcPlac，Inc.的VisualWave系统上。1997年，对设计文档系统进行了改进，发布了设计文档，分布式设计人员可以通过Internet上的Web浏览器访问设计文档，以进行协同的知识密集型工程活动。以机械设计支持系统为例，验证了知识密集型机械设计支持系统的有效性。

This research aimed at fundamental investigation to develop a machine dsign support system based on the ideas of knowledge intensive engineering. Knowledge intensive engineeering is a new type of engineering which flexibly utilizes a large amount of engineering knowlede, including codified and non-codified knowledg to generate more added value. The research tackled the following three isssues.(1) Fundamental research into the integration of codified knowledge and nono-codified knowledge using hypertext technology and network technology.(2) Fundamental research into handling knowledge about whole of the product life cycle, including design, production, operation, maintenance, and reuse and recycling.(3) The development of fundamental technologies for the knowledge intensive machine dsign support system and its prototype.In 1995 and 1996, regarding issues (1) and (3) , a hypertext based design documentation system was developed. This system can integrate both codifed and non-codifed knowledge including visual information. It c record, edit, and reuse operations to the KIEF (Knowledge Intensive Engineering Framework) system that was seperately developed by our group to support knowledge intensive engineering activities. The recorded design documentation is created in the HTML format and the system runs on Visual Wave system of ParcPlac, Inc.In 1997, the design documentation system was improved to issue design documents that can be accesed by distributed designers through WEB browsers on Internet to conduct collaboratively knowledge intensive engineering activities.Regarding issue (2) , in 1996.a varuety of product life cycle knowledge was experimentally collected an in 1997 implemented on the design documentation system. A case study of machine dsign was conducted to demonstrate the effectiveness of the knowledge intensive machine design support system.
