In theoretical research and practical approaches to implementing innovative developments, there is a gap in the holistic understanding of terms related to the digital economy, the scope and content of this concept. The research problem is to understand the concepts of digital twin, its place and role in digital economy, digitalization, and industry 4.0. The purpose of this study is to clarify the content of these concepts, with the formation of a comprehensive management approach to their practical implementation in industrial supply chains, with the harmonious participation of various specialists related to the problems of modern production. Technologies, methods, technical solutions, and best practices should become significant in the processes of modern supply chains. The article provides an overview of theoretical research and current trends in the development of the concept of "digital economy", analyzes the technical and economic grounds for such changes, and defines the directions for further development of such research. The difference between engineering and economic approaches to the problem of production management is shown. The authors substantiate the urgency of the translation of models of supply chains in a digital format. The goal of the proposed digital model is to find the optimal criterion of economic efficiency and get recommendations for building a logistics cycle for the selected planning horizon on the example of the Huawei enterprise. In conclusion, the article considers the concept of "digital twin" of supply chain processes, which is correlated with simulation methods. The simulation and digital twin are considered as the optimization procedures for optimal control, important and promising technical procedures of industry 4.0. Based on the study of the literature, the characteristics and properties of "digital twins", the importance for production management and other processes of supply chains are highlighted.
