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

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。

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.
