The article presents theoretical research on model-based tools used in engineering practice and specialist training in the form of software systems for describing modern technological processes in the industrial machine-building sector as digital twins. An analysis of a simulation model of a specific technological section of a real Ukrainian enterprise engaged in the production of wooden windows is conducted using the Product Lifecycle Management (PLM) system Tecnomatix Plant Simulation, along with a review of recent studies applying this software. Measures for enterprise modernization are proposed, including structural reorganization of logistics processes within the technological section and the implementation of computer numerical control (CNC) machines for selected operations to replace existing equipment. As a result of a parametric analysis of the operation of the modernized technological line, technical measures aimed at improving production efficiency are identified. The impact of machine utilization data based on technical characteristics is analyzed in detail, and a comparative analysis of key performance indicators in accordance with the ISO 22400 standard is performed. In particular, the defect rate coefficient after structural and logistical reconfiguration of the virtual technological line for wooden window production is evaluated. Simulation modeling produced a significant amount of statistically processed virtual sensor data, enabling the development and integration of neural network models into the digital twin architecture of the industrial system. Technical proposals at the level of model-based solutions are formulated, and the operation of the technological section is visualized to support simulation, evaluation, and engineering decision-making within the PLM system Tecnomatix Plant Simulation. Selected results of simulation modeling of production processes, the sequence of modeling procedures, as well as methods for evaluation and visualization are adopted for use in the training of specialists within the master’s educational program “Smart Industry” at Kherson National Technical University and the bachelor’s educational program “Engineering Technologies, Mechatronics, and 3D Printing” at Central Ukrainian National Technical University under the specialty G9 “Applied Mechanics.”
