• Scientific concepts of development of the heat economy and the Unified Gas Supply System of the country. 
• Methods for coordination of decisions taken in individual sectors of the economy and the energy sector. 
• Information and computational bases for studies, solution of the problems on development, management of operation and dispatching control of different pipeline systems including the Unified Gas Supply System, systems of main gas pipelines, water supply, heat supply and the heat economy of Russia and its regions. 
• Databases, complexes of dialog software, work stations and other program packages. 

Applied projects.

The department participates in large-scale international, federal and regional projects: the international project TACIS (Environmentally clean energy supply of the Baikal region); energy saving projects in the heat economy of regions and cities; project on the gas export “Yamal – Europe”; project on gas industry development in Russia in the eastern geopolitical direction; concepts and projects on the energy development options in Russia and their effect on the terms and scales of development of the national gas industry and heat economy; price and tariff policy in the heat supply sector, etc.

Software development. 

The program packages developed by the department have been extensively applied in calculations, optimization of development and dispatching control of many real objects such as: systems of heat supply to the cities of Kiev, Irkutsk, Omsk, Novosibirsk, Tyumen, Angarsk, Sterlitamak etc.; systems of main oil pipelines of West and North-Western Siberia, Ural-Siberian region; water-supplying systems of cities and industrial plants in Irkutsk, Angarsk, Usolie-Sibirskoye, Petrozavodsk and so on. They have been implemented in some organizations of the Ministry of Fuel and Energy, oil and gas industry, enterprises of heat networks, departments of water supply and sewerage systems of cities and industrial plants of mining and petrochemical industries, design institutes and higher educational establishments of the country and abroad.
