Workflow-based Collaborative Design System

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.
