The article discusses application of system analysis to identify and solve the problems of energy efficiency of machine-building enterprises. The increase in the efficiency of a machine-building enterprise is influenced by many factors, among which tariffs and prices for energy services have a significant impact. The increase in tariffs for these services has a direct impact on the increase in cost. Energy efficiency objectives also include: high energy capacity of products; insufficient efficiency of generation, transportation and distribution of energy resources; low reliability of power supply; insufficient volume or low reliability of information on the energy infrastructure operation. As a result of the system analysis, directions have been identified that enable one to increase energy efficiency, which leads to a decrease in the cost of production, and, consequently, to an increase in the profit of the enterprise. Directions for increasing the energy efficiency of machine-building enterprises can be identified as a result of system studies of the activities of all divisions of the main, auxiliary and service industries. The greatest effect from energy-saving measures is achieved in the process of rational energy consumption, which is advisable to implement at machine-building enterprises. Reduced production output caused by the global economic crisis that began in 2008 and the impact of the 2020-2021 pandemic have resulted in the equipment operation at reduced loads and in off-design modes, which in turn has led to the auxiliary equipment consuming almost the same amount of energy as at nominal performance. This circumstance leads to an increase in costs. A mathematical model has been developed, in which a machine-building enterprise is considered as a set of functional elements and components with a hierarchical structure of connections between them, described in the form of a ‘6-tuple’.
