Manufacturing industry needs a more effective and unified information system to meet market demand changes and societal/environmental requirements. The international standard ISO/IEC 62264 (an adoption of ISA SP95) presents an integrated framework for business planning & logistics, manufacturing operation management, and control. The information system integration models proposed in this standard are based on UML (Unified Modeling Language). OPM (Object Process Methodology) is a new modeling approach with much more advantages comparing to UML. This paper re-builds the information system integration models in ISO/IEC 62264 based on OPM. The application in an oil refinery factory verifies the effectiveness of these models and the convenience of OPM.
