Abstract: Industrial design process modeling is the key of product design process management study,
which directly affects the development cycle and overall benefits of projects. However, there is no
effective modeling technology and system for design process management in current industrial design
fields. In order to realize the dynamic, structural and orderly management of the design process of
industrial design enterprises, we introduce process oriented organization management, process
optimization of workflow technology and Petri net modeling method in the product design process
management. Then, according to the research on the design process management process, the design
process management workflow flowchart is constructed. In addition, combining with workflow
technology, Petri net modeling method and the industrial design process management flow, this paper
proposes a four-stage workflow modeling method for industrial design process management: ontology
analysis, element extraction, element generalization and element introduction. Finally, based on Petri
net, a workflow management model of industrial design process management is built, and accordingly,
the industrial design process management prototype system is realized.

Key words: industrial design process management, Petri net, workflow
