Abstract
"In today's competitive business environment, it is vitally important to be able to reduce product development time and lower costs. The purpose of this research is to develop a web-based collaborative design and manufacturing system which could drastically decrease product development time. The entire system is composed of three modules- collaboration, design, and manufacturing.
The design by features system has been recognized for allowing designers to create a part faster. However, most of the design by features systems lack extension and evaluation capabilities. Unfortunately, these two capabilities play an important role in the design system. The first paper included in this dissertation introduces two auxiliary mechanisms to support designers by extending the feature library, and by evaluating the design part. Besides, the first paper also discusses the development of a web-based platform-independent collaboration module which allows a designer to exchange his/her opinions with customers or manufacturers via the Internet.
For manufacturers, the process plans for parts are typically generated from scratch. However, it is a tedious and time-consuming task. In the past, the case-based reasoning (CBR) has been successfully applied in various fields. In CBR, new solutions are generated by retrieving the most relevant case from the case library and adapting it to fit the new situations. The second paper and the third paper included in this dissertation discuss the development of case- based process planners to assist manufacturers in generating the process plans for axisymmetric parts and prismatic parts, respectively.
Examples shown in these three papers are used to demonstrate the developed theories and algorithms. The entire proposed system has been implemented on a Sun workstation using the ACIS geometric modeler and C++. In addition, the platform-independent collaboration module among designers/customers/manufacturers is written in JAVA and VRML"--Abstract, page iv.
