Abstract: CIPS is a synthetic automation system engineering in which the process enterprises can carry their industries into modern information practice, make information integration and process integration among all their information systems so as to improve their competition power in markets. The essence of CIPS is system integration and technology fusion. In order to obtain this goal, the process enterprises need a set of advanced methodologies and support tools urgently to direct and support the planning and implementation of CIPS. As we can see, enterprise integrated modeling techniques make it possible to turn the enterprise modeling theories into operable enterprise models effectively and also provide the above methodologies and support tools. In addition, enterprise integrated modeling techniques have shorten the gap between CIPS research theories and CIPS engineering implementation. Based on the description of the application characters and system makeup of CIPS, this paper describes the trends of enterprise integrated modeling techniques in CIPS and their key technologies. This paper also presents the enterprise integrated modeling architecture in CIPS and the process framework of enterprise integrated modeling. Undoubtedly, this research on the enterprise integrated modeling techniques in CIPS will promote the theory research and system application levels of CIPS.
