The system is based on the globally shared product model conforming to VRML Standard. The system takes sugarcane harvester design analysis and evaluation as an example, and utilizes fuzzy evaluation principle to evaluate the design and analysis results for decisions making. The platform provides a collaborative intelligent environment for the design of products, aiming at integrating people, process and data in the virtual product development.

In this paper, we illustrate PDM framework layer, a configuration model layer,a functional model layer, a fuzzy reasoning layer, an integration layer for I-DEAS and CIDS, Service-Oriented Conception Design (SOCD) Model layer, design evaluation layer, a computer methods layer and a personal Web Graphical User Interface (GUI) and so on.
