Effects of digitalization of production systems determine the growing interest of enterprises in comprehensive process modernization. Creating a digital factory model enables the implementation of a systematic approach to the digital transformation of an enterprise, ensuring improved quality of processes and products, reliability, and production ef ciency. Consideration of the industry-speci c nature of technological processes is of great importance. The authors focus on the problems of modeling a digital factory for aluminum production. The purpose of the study is to develop a structural-parametric model of a digital factory adapted for enterprises in the aluminum industry. In the course of the study, by systematizing the problem eld, characteristics, regulatory framework, and principles, a conceptual framework for modeling aluminum production was constructed, providing a theoretical basis for creating a digital factory model; a structural-parametric model of a digital factory for aluminum production (using the example of a quality management system) was proposed, integrating modern digital tools and a hierarchical ow management system; the role of digital twins in the digital factory model was substantiated. Modeling a digital factory for aluminum production makes it possible to solve the problem of import substitution and ensure technological sovereignty.
