基于综合集成法的复杂产品协同设计过程模型及框架研究

建立过程模型及框架，将设计过程有效地表达出来，是协同设计的基础。 论文针对复杂产品设计过程的特征，根据综合集成法，建立了一个以时间、粒度、并行度三 维分布的多层次复杂产品协同设计过程模型。该过程模型在时间维强调多阶段综合，在并行 度维强调多专业综合，在粒度维强调分解与综合的迭代。在该过程模型基础上，结合专家体 系、知识体系、机器体系，提出基于综合集成法的复杂产品协同设计过程框架。该框架中， 机器体系依靠知识体系中的知识，给专家群体提供帮助，专家群体在机器体系提供的项目管 理、群体研讨、协同决策、三维可视化等支持工具帮助下，实现人机结合、多专业结合、多 阶段结合的协同设计过程，以提高复杂产品的协同设计效率。最后介绍了相关原型系统。

Research on Process Model and Framework of Collaborative Design forComplex Product Based on Meta-synthesis

To express the design process effectively by establishing the process model and framework is the foundation of collaborative design. According to the features of design process for complex product, a multi-level process model of collaborative design for complex product based on the dimensions of time, particle size and parallelism is established, combining with meta-synthesis. This process model emphasizes on the combinations of multi-stage in time dimension, combinations of multi-specialty in parallelism dimension and iteration of decomposition and integration in particle dimension. Then, on the base of the process model, a process framework of collaborative design for complex product based on meta-synthesis is proposed, combining with expert system, knowledge system and machinery system. Machinery system helps the expert group with knowledge from knowledge system. Expert system fulfills the collaborative design process of combinations of human-computer, multi-specialty and multi-stage, with the services provided by machinery system, e.g. project management, group argumentation, collaborative decision and 3D visualization. Finally the prototype system which has been developed based on the idea of this paper is introduced.
