Fundamental Research on the Knowledge Intensive Machine Design Support System

本研究的目的是为开发一个基于知识密集型工程思想的机械设计支持系统进行基础性的研究。知识密集型工程是一种新型的工程，它灵活地利用大量的工程知识，包括编码和非编码知识，以产生更多的附加值。研究解决了以下三个问题。(1)运用超文本技术与网络技术整合编码化知识与非编码化知识之基础研究。(2)对产品生命周期的知识处理进行基础研究，包括设计，生产，运营，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本技术的发展1995年和1996年，关于问题（1）和（3），开发了一个基于超文本的设计文档系统。该系统可以整合编码和非编码的知识，包括视觉信息。它可以记录、编辑和重用由我们小组单独开发的支持知识密集型工程活动的KIEF（知识密集型工程框架）系统。记录的设计文档以HTML格式创建，并且该系统在ParcPlac公司的Visual Wave系统上运行。1997年，设计文档系统被改进为发布设计文档，该设计文档可以由分布式设计者通过互联网上的WEB浏览器访问，以进行协作的知识密集型工程活动。关于问题（2），1996年，通过实验收集了各种产品生命周期知识，并于1997年在设计文档系统中实施。以机械设计为例，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.
