A Kind Of Integration Model Of Digital Enterprise In Discrete Sector

"Digital Enterprise"is a kind of new model of modern enterprise operation. With the combination of information technology, modern management technology and advanced manufacturing technology, it can be applied in the whole product life cycle and every section of enterprise operation and management. Digital enterprise can realize the digitalization and integration of product design and manufacturing digitalized, management digitalized, process digitalized, manufacturing equipment, can improve enterprise's product development ability, managerial skills and manufacturing capability, thereby enhance the comprehensive competitive power."Integration" is an important feature and content of "digital enterprise", it involves integration of decision level, operation and management level and execution level inside enterprise, and then involves integration of enterprise and its suppliers, vendors, partners and customers, etc outside enterprise.Different industry has different content in enterprise informatization, so does the integration models of "digital enterprise". Based on the characteristics of discrete manufacturing industries and the integration needs of discrete manufacturing-oriented "digital enterprise", this paper researches the integration model of "digital enterprise" in discrete manufacturing industry.Firstly, an integration architecture of "digital enterprise"in discrete manufacturing is established, based on analysis of the description model of digital enterprise. It involves integration hierarchy system, integration content system and integration technical system.Secondly, according to the needs of"flexible, agility and loose coupling"in the"digital enterprise"integration, this paper puts forward a flexible integration method of discrete in manufacturing digital enterprise, and some key techniques which including information exchange specification, information mapping configuration, MOM and agent technique were studied.The content discussed in this paper is an important part of the National 863 Planning Project-the development of integration between workshop equipment and enterprise's design/management information system (2005AA415300),and it has been applied in the construction of "digital enterprise" in JiangJin turbocharger plant. This subject has already passed acceptance check which the State Ministry of Science and Technology organizes.
