System metamodel of the multi-agent digital twin of the subject-oriented IT-platform ME-U

Abstract

The article discusses models of a multi-agent digital twin (DT) of a corporate applied IT platform that provides integrated geographically distributed interaction between a university and a manufacturing enterprise in the development of complex, high-tech objects in the context of digital transformation and transition to INDUSTRY 4.0 technologies. A necessary and sufficient condition for the existence of a DT is given. A system metamodel of the digital domain is presented, which ensures the integrity of the description and consistent presentation of the subject area under study. A method for creating and transforming the architecture of the digital data center of a corporate applied IT platform based on the theory of categories and the TOGAF methodology is proposed. An example of the application of the proposed models and method in the creation and use of the data center of the corporate information system of PJSC "UEC-UMPO" in FGBOU VO "UUSiT" is given. The effectiveness of the proposed solutions is confirmed by the volume of work performed with the use of digital data in the following areas: solving production problems, educational activities and performing research.
