支持协同产品开发的约束模型研究

Research on Constraint Model Supporting Cooperative Product Development

约束是协调来自产品全生命周期中的各种要求、关系和规范的有效手段。本文分析了协同产品开发中约束的特点 ,在此基础上 ,根据问题求解理论提出了一种变粒度约束网络模型 ,研究了变粒度约束网络中的映射规则 ,以及变粒度约束网络的性质和特点 。

Constraint management is a kind of effective method to coordinate all the requirements, rules arising from the product life cycle. In the paper, the characters of constraint in cooperative product development process are analyzed firstly. According to the problem solving theory, a kind of constraint model with different granules is proposed and the mapping rules of this constraint model are researched. A distributed constraint management system basing on this constraint model is introduced at the end of this paper. It shows this novel constraint model can meet the needs of the cooperative product development.
