SIMULATION AS THE BASIS OF DIGITAL TWIN TECHNOLOGY

Abstract

The PURPOSE of the study is evaluation of the role and significance of simulation models in digital twin construction and operation. METHODS. The main research methods are system analysis and methodology, techniques and construction methods of simulation models. RESULTS. Having analyzed the technologies for digital twin creation and use, the author shows that simulation models form the basis for their existence. The information technology used in this case is a tool providing digital twin operation but it is not a determining factor. The quality of the constructed simulation model determines the efficiency of digital twin technology creation, use and development. CONCLUSION. To improve the quality of a digital twin simulation core a list of problems that need to be solved is formulated. They include automation of statistical analysis of time series, which is completed with an intuitive explanation of analysis results and generation of the sets of random numbers with certain probabilistic properties; development of quality assessment methods of the selected tools of simulation modeling; creation of quality assessment methods for digital twin core transformation in the process of its modernization based on the results of field operation and formation of methodology, methods, algorithmic tools and software; creation of digital twins of poorly formalized systems.
