The paper presents the main approaches to digital twin formation taking into account many years of research. A concept for the creation of digital twins is proposed, with regard to the evolution of the current state of the object. A digital twin is an innovative concept that is becoming increasingly relevant with the development of the fourth industrial revolution and the transition to intelligent manufacturing. The paper provides an analysis of works in the field of digital twins, considers specific features of the concept application in manufacturing, analyzes the main problems associated with its practical implementation and their possible solutions. The work places particular emphasis on the features of the multiphysics model formation, the specifics of working with large arrays of heterogeneous data for digital twins and the requirements for cyberphysical technological systems that are their prototypes.
Keywords: digital twins, cyber-physical systems (CPS), industrial Internet of things (IIoT), big data and cloud computing technologies, multiphysics mathematical models.
