Research of Dynamic Workflow Change in PDM Systems

Workflow management is a key tech-nology for the business process management and control in PDM. But,mostly existing workflow management systems are designed to handlestatic business process. When a dynamic change occurs, these usuallystop the affected workflow and restart the new workflow that is modi-fied, which lead to re- execution of nodes in new workflow. This paperproposes an approach to reducing repetitive execution of nodes by ana-lyzing the property and estate of nodes in the new workflow, to improvethe availability of the enterprise.
