Workflow Model Design Based on N-Tree for Process Management in PDM
In this paper, a workflow model based on N-tree for process management in PDM system is presented. It streamlines circuits in process management to sequence, branch, parallel, and loop patterns. It also offers this workflow model’s mechanisms of construction, executing, and state transition by definitions of workflow’s node properties, node constraints and state set. Last it exhibits an instance of applying this workflow model to process management of a simple PDM system.
