Application of Polychromatic Graph in Workflow Versioning

Traditional workflow performs well in structured business process. For the Internet-based manufacturing, however, this method does not meet the requirements of inter organization business process and information modeling. Based on polychromatic graph it presents a dynamic workflow model. With simple activity and composition activity, the model can be defined in hierarchy and supported multi version of workflow from the polychromatic character. It introduces an approach for version comparison to clarify version differences and provide supporting for workflow instance migration. The application case proves the hierarchy and multi version character.
