Abstract:

Workflow management of collaborative virtual prototype supports and controls the dynamic and collaborative process of designs by many integrated productdeveloping teams distributed here and there, thus to achieve effective management of the collaborative design process, which plays an important role in improving work efficiency and quality of the virtual prototype. This paper mainly studies the workflow time management of the virtual prototype. By analyzing the routing structures, adopting workflow relaxation time distribution method, and adjusting some weak and demanding time constraints to their satisfactory state, more workflow instances can be enabled to meet deadlines, thus reducing the abnormal triggering frequency, saving the processing cost, and improving operation efficiency.

Key words: collaborative virtual prototype；workflow time management；time constraints
