Abstract

In order to shorten new product development cycles, parallel approach is emphasized to organize and plan the process of product design in Collaborative Product Development (CPD), in which a great deal of constraints of interdependent, interactive and restrictive relationships exist. The motivation of this article is to provide a simple and effective method to solve this problem. In new product development, collaboration is usually conducted according to product structure. In accordance with this principle, a constraint network is presented and an algorithm is given out. While the constraints can not be met, then conflict will arise. A consultation model is established. Finally, a case is put forward to explain how the algorithm for constraint network and consultation model work.
