【摘要】 本文首先研究了协同设计的基本概念，针对协同设计的任务分配的问题，提出了一个基于工作流的解决方案。在此基础上，阐述了工作流系统的组成和结构，选择了Petri网为工作流建模手段，详细研究了利用Petri网进行工作流建模的方法，并利用时序Petri网对基于工作流的协同设计模型进行了分析。针对协同设计的多样性，本课题以机械设计为依托研究了在协同设计中必须解决的若干问题，并提出了相应的解决方法。在实现机制方面，分析了CSCW的系统结构，并在CSCW的基础上，提出了本系统的分布式组成原理，从而实现了利用工作流技术，在CSCW框架内构建计算机支持的协同设计(CSCD)系统的设想。 本课题的主要成果是开发了一个基于工作流的协同设计系统，利用该系统可以为机械协同设计提供一个方便实用的平台，为多人协作完成一个设计目标提供了一个切实可行的途径。更多还原

【Abstract】 This paper firstly studies the elementary concepts of Co-Design, then a resolution based on Workflow is put forward to in allusion to the problem of assignment of task in Co-Design. On the base of this circs, we expatiate the buildup and structure of Workflow and select PetriNet as instrument of Workflow modeling. Then detailedly study how to set up the Workflow by PetriNet, and analyse modeling of Co-Design based of Workflow with scheduling PetriNet. Because of the diversity of Co-Design, this paper chooses mechanical design as bracket to study several problems which must be solved in Co-Design, then brings forward corresponding solutions. In the field of realization mechanism, we study the architecture of CSCW, then put forward to the distributed composing principle of this system. So the concept of establishing a system for CSCD in the frame of CSCW using the technology of Workflow is realized.The main fruit of this research is a system for Co-Design based on Workflow. It is a convenient platform for mechanical Co-Design which provides a feasible route for multi-person to cooperate and finish a design aim.更多还原
