Currently, the methodology of system engineering is being formed, the product of which is, as usual, the creation of real objects information models, supplemented by virtual components, and on the contrary, virtual objects, supplemented by real components. For example, an information model of a technological object is a specification of real equipment, supplemented by a specification of the purchased equipment of a technological process and on the contrary. By analogy with general engineering in the field of technical activity, the metastructures of such information models must meet the V-shaped structure of the validation and verification processes. Therefore, models should be regularly checked during their life cycle to ensure that their structure and parameters correspond to real and virtual objects. At the present, there are conditions for a coordinated decision of technological objects system information modeling, taking into account their internal (physical) structure and of the digital environment the external structure. In general theoretical terms, the construction of system models is based on the problem of formal consistent description (grammatical calculus) of the structure and functional regularities of a set of objects and their connections in the subject area under study. The presented approach of the subject area system modeling under consideration is based on the classical model of a machine-building enterprise (MP) educational and production activities and a university. Aim. To apply the principles of the design approach for the formation of a corporate information system (CIS) engineering company metastructure digital twin, to explore the prospects of its application, to show the key information components in the management of subject-oriented knowledge and data, as well as the ability to scale technology in the formation of a digital environment for architecture and modern MP, improving the efficiency of business processes participants interaction. Materials and methods. The principles of the system engineering methodo¬logy (process approach, life cycle, etc.), an integrated approach and structural analysis of the design process according to the SADT (Structured Analysis and Design Technology) methodology, and the TOGAF (The Open Group Architecture Framework) methodology are used. Results. The proposed approach for system modeling the subject area is the development of works of the authors, demonstrates the possibility of scaling on the example of interaction of participants of the REC using part of the University's digital twin KIS enterprises of the real sector of the economy. The requisite of developing a knowledge management model and the increasing role of information search engines are shown. Conclusion. The proposed approach expands the application of the digital twin metastructure, allows correcting the enterprise architecture to improve the efficiency of business processes.
