Application of the Digital Twin Concept to Solve the Monitoring Task of Machine-Building Technological Process

The digital twin (DT) of a process is a prospective tool for designing modern digital productions based on the Industry 4.0 concept. The development of technological process (TP) DT provides a large amount of data acquisition connected with product processing into a single information structure. The structure may contain the values of different technological parameters and the workshop's utilized resources data. From this point of view, the monitoring of machine-building TP can be implemented and based on the DT process. The development of this approach was the purpose of the research. The scientific publication analysis showed the approach under consideration is relevant and insufficiently developed from a scientific point of view. The authors propose the structure of TP DT for high variety low volume machine-building production in this paper. The possibility of its application for the majority of these types of production is proved. An algorithm for solving the TP monitoring task based on the DT process is described.
