Abstract: A general change information description and integration method between Product Data Management (PDM) and Enterprise Resource Planning (ERP) systems, and a change control strategy based on work flow technology were proposed. Change information was classified into three basic forms as object component, hierarchical structure and document. A general method of change information description was developed accordingly. Change increment information was shared and integrated between the two systems based on a neutral data environment. Relevant information in change process was labeled as change information, upgrade information and assistant information, while transmission, tracking and information release were accomplished by workflow technology so that change processes could be controlled. Information resulted from a change process was released in a new version with association upgrade and association inheritance. The change information integration and control method was illustrated with an implementation practice between a PDM system and an ERP system in an enterprise. It provided effective solution to change integration and management between PDM and ERP systems.
