Abstract

One of the main tasks of recent years is the development of the Arctic region of Russia. This is due to the economic, political and defense interests of the country. The Arctic zone is characterized by harsh climatic conditions and, as a consequence, high consumption of energy resources to ensure uninterrupted operation of heat supply systems. Taking into account the fact that fuel oil, supplied from other regions, is used as the main type of fuel, the issue of energy efficiency of heat supply systems is quite acute. The proposed methodology for assessing energy efficiency is based on several mathematical methods, including the method of correlation analysis, the method of ranking of indicators and the method of expert criterion evaluation. Generalization of these methods as applied to the heat supply system allowed to create a methodology of criteria assessment of energy efficiency of heat supply systems, allowing with minimal time and with high accuracy to evaluate the effectiveness of the entire system and its individual components. In addition, the application of criteria assessment makes it possible to determine the most relevant areas of energy saving of heat supply systems and to assess the technical and economic effect from the implementation of a particular energy saving measure, taking into account a wide range of external factors and the characteristics of specific heat supply systems.
