Gaiduchok O. System Modeling of Economy with Energy Sector.

In dissertation research scientific methods of construction and analysis of model solutions of economic development for the energy dependent economy (with different types of energy resources) are developed and justified. The need of building model that should be analytical, continuous, non-linear, is shown. A system analysis of two-sector economy, describing the economic agents - production, population, the banking system and markets - energy market, market of energy materials, product market, labor market, capital market has been produced. The model of economic development for energy dependent market economy as closed system of differential and functional equations for determining the main macroeconomic indicators has been constructed. The new model, depending on different types of energy resources, is introduced by changing second sector in which energy materials are processed (gas, oil and coal are supplied from outside by defined prices) for the needs of the population and for the production of the first sector product. The complete model, which takes into account the economic dependence of prices of imported coal, oil and gas, as a closed system of functional and differential equations is constructed. The numerical experiments with the system projected economic development received by the constructed model are presented as graphs of the dynamics of main macroeconomic indicators.
