Факультет бизнес-информатики и управления комплексными системами
ФБИУКС осуществляет образовательную деятельность по программам бакалавриата, магистратуры и аспирантуры.
Ведется научно-инновационная деятельность и разработка научных комплексных проектов по направлению «мезоэкономика» в кооперации с академическими институтами РАН: Центральным экономико-математическим институтом (ЦЭМИ РАН) и Институтом народнохозяйственного прогнозирования (ИНП РАН), создание бизнес-моделей инновационного развития «мезоэкономических» систем — крупных корпораций и территориальных комплексов (территорий опережающего развития — ТОР).
Уникальные преимущества обучения на факультете связаны с выдающимися отечественными учеными, являющимися профессорами факультета. Академик РАН, директор ИНП РАН В.В. Ивантер, члены-корреспонденты РАН Г.Б. Клейнер, Б.Н. Порфирьев, Д.Е. Сорокин и многие другие — это «золотой фонд» образовательного комплекса факультета и одновременно мощный научный центр, обеспечивающий исследования и разработки на самом современном уровне.

- ПубликацияТолько метаданныеInvestment Performance Predictions in the Digitization of Nuclear Energy(2021) Akinfeeva, E. V.; Kharitonov, V. V.; Semenova, D. Y.; Харитонов, Владимир Витальевич; Семенова, Дарья Юрьевна; Факультет бизнес-информатики и управления комплексными системами© 2021, Pleiades Publishing, Ltd.Abstract—: The article proposes an analytical method for predicting the efficiency of investments in the digitalization of the design, construction and operation of nuclear power plants (NPPs) at the microeconomic level, the costs of which ultimately affect the economic indicators of nuclear power plants that determine the competitiveness of nuclear energy in the energy technology market. As a criterion for assessing the effectiveness of investments in the digitalization of nuclear energy, it is proposed to consider the reduction in the cost and timing of the construction of nuclear power plants, which have the greatest impact on the competitiveness of nuclear power plants. The results of calculating the present value of NPP electricity, the investment payback period and the internal rate of return, depending on the observed delays and the corresponding growth in the cost of NPP construction, demonstrate reserves for their reduction due to the digitalization of business processes in the NPP life cycle.
- ПубликацияТолько метаданныеThe value of spent nuclear fuel as a raw material for fueling reactors on thermal neutrons(2019) Uliyanin, Yu. A.; Soloveva, A. P.; Kharitonov, V. V.; Yurshina, D. Yu.; Харитонов, Владимир Витальевич; Семенова, Дарья Юрьевна; Факультет бизнес-информатики и управления комплексными системами© 2019 Obninsk Institute for Nuclear Power Engineering, National Research Nuclear University 'MEPhI'. All rights reserved.An analytical model is presented to determine the energy and economic value of SNF as a raw material for thermal reactors' fuel and to identify the period of time when the energy demand for mass production of fuel from SNF appears. Possible scenarios for using of fuel resources from SNF for compensation of the predicted shortage of natural uranium which occurs from the exhaustion of deposits with the lowest cost of production and limited resources with a cost price of up to $ 260/kgU (with available forecasts of recoverable resources) are given. From the energy (resource) point of view, there is no need in large-scale SNF reprocessing for thermal reactors fuel production almost until 2040. The need to reprocess SNF in the coming decades is determined not by resource considerations, but by the necessity to reduce the amount of highly radioactive waste, develop industrial technologies of SNF treatment for the future safe and economically acceptable closed nuclear fuel cycle (NFC), increase the competitiveness of fuel companies on a global market due to the integrated offer of NFC services, etc. Calculations of the fuel component in the cost of electricity produced by nuclear power plants with REMIX-fuel are made. REMIX-fuel is obtained by adding a certain amount of highly enriched uranium (up to 20%) to an unseparated mixture of uranium and plutonium in the reprocessed SNF which is purified from fission products and has a fissionable nuclide concentration of 1 - 2%. The enrichment of this additive has little effect on the REMIX-fuel price, since its price increases with an increase in the additive enrichment, but the mass fraction necessary for obtaining a given enrichment of fuel from thermal reactors decreases. A concept of SNF reprocessing value for the production of REMIX-fuel is presented with the method of its calculation. The higher the value of SNF reprocessing, the more profitable the production of REMIX-fuel for thermal reactors.

- ПубликацияОткрытый доступForecasting the cost and volume of uranium mining for different world nuclear energy development scenarios(2024) Mirkhusanov, U. T.; Semenova, D. Y.; Kharitonov, V. V.; Семенова, Дарья Юрьевна; Харитонов, Владимир Витальевич; Факультет бизнес-информатики и управления комплексными системамиThe paper presents a new analytical methodology for predicting the volume and cost of natural uranium production depending on uranium resources and scenarios for the development of traditional nuclear energy. The proposed methodology is based on a mathematical model of the dynamic process of exhaustion of fossil resources previously developed at MEPhI and uses the parameters of the explored mass of the fossil resource, the annual volume of production and the set rate of production growth. The three parameters known at the beginning of forecasting make it possible to describe the change in the resource base over time and solve a number of economic problems related to the extraction of valuable minerals. The paper provides forecasts of the NPP’s demand for natural uranium, depending on the scenarios for the development of global nuclear energy developed by the World Nuclear Association (WNA), uranium resources and volumes of its production with different costs for 2021–2022. It is shown that at a low rate (1.8%/year) of the installed capacity of nuclear power plants, uranium resources will last for more than a century, but the contribution of nuclear energy to electricity production will continuously decrease from the current 10%. Under high scenarios for the development of nuclear energy (>5%/year), which is possible under the conditions of intensification of the “green energy transition”, the peak of uranium production may occur before the middle of this century. Based on these data, forecasts of the dynamics of uranium exhaustion and annual production volumes at fields with different costs are presented until the second half of this century, depending on the initial production growth rates determined by the scenario of nuclear energy development.
