System-Information Models of Digital Twins

Abstract

To represent the production process, a digital twin model is used, which takes into account the real parameters of technological processes. Management of product life cycle processes is implemented on the basis of a digital twin of the Unified System Information Space (USIS), built on system-information models of processes and systems. It is used as a platform for management using software products Product Lifecycle System Information (PLSI), which are system-compatible with technological system software Product Lifecycle Management (PLM). The digital twin describes the functional dependence of the expanded uncertainty of the normalized information space on the values of the nominal parameters for a specific production technology using a software product (USIS + PLSI + PLM). This allows you to use software products for designing CAD, CAM, and CAE systems when solving production problems on one information platform. Using a system-information approach to modeling digital twins of production allows you to effectively solve problems related to the analysis, synthesis, management, and forecasting of production.
