SCOPE

The invention relates to the field of modeling of economic processes management of enterprises and can be used to implement simulation models of different parts of the economy of the objects of the national economy.

PRIOR art

Known [1] the system of investment Advisory and funds management pension funds, which includes a device for storing worksheets and input of data by clients of the Fund, the device data in the tables, the model prediction of funds between different types of assets, distribution of funds between different types of assets and investments, the processing device to reconcile the client's risk by type of investment, output device to generate recommendations on investing. However, in the system there is no source of statistical information for each type of investment. In addition, it is obvious the lack of feedback, allowing for the reaction of the customer to make a correction of the results and find the best solutions.

A known system for managing the sale of goods [2], which includes the memory block data about customers-applicants, the processing unit demand for goods, the subsystem of formation of market prices, as well as forming unit output the message.

However, in this system there are no blocks, analyzing potential effective demand, allowing more accurate modeling of the flows of supply and demand.

Known automated system for additional income [3], which includes a set of blocks, receiving, processing and displaying graphically economic information about each qualifying company, the control unit with information about market conditions, credit and investment spheres, the block comparison of economic indicators from each of the enterprises with indicators from the database and generating the signal of the difference between the actual and planned performance. However, based on the description in this system compares actual performance with the previously generated and possibly outdated performance and appearance as a result of misinterpretation.

Closest to the proposed invention can be regarded as the invention, a system for modeling processes of the market economy management [4], which includes a subtraction unit, the block of formation of market prices, the computing unit implemented sales, the computing unit taxes on producers ' incomes and consumption, block modeling consumption, the adder and the computing unit of investment and amount of accumulation

This system provides the possibility of modeling of management processes in the region, industry or enterprise. However, at the macroeconomic level, the disadvantages of this system are factors that reduce the accuracy of the simulation, including the difficulty of forming credible intervals of the weighted and normalized market prices throughout the economy as a whole, where the number of price positions is hundreds of thousands of units. According to all known economic theories of equilibrium between supply and demand on the market of goods and services determines the equilibrium price, so the incorrect definition, and then use change rates as the primary control signal may cause significant errors of prediction results characteristics of the simulated processes. The use of total goods and services total amount of production costs and profits allocated to the accumulation, incorrect, as this part of the profit is only partially spent on the purchase of goods and services. Enter in block modeling consumption investment partially increases consumption, however, increases the amount of debt of entities of national economy, respectively, reduces the consumption of the same amount of investment.

The technical result,which sent the invention, is the creation of dynamic system modeling of economic management, allowing to improve the accuracy and usefulness of the forecasting real economic output parameters by modeling dependencies between effective demand and effective proposal - volume offered on the market of goods and services, including

- trends of economic development in the areas of supply and demand, given in the form of numerical coefficients and recommendations for expansion or reduction of funding level of production of goods and services,

- changes in the levels of savings in the real sector of the economy, describing the growth of wealth of the subjects of the national economy,

- changes in the value of fixed assets, capitalization of interest of the national economy,

- estimated foreign borrowing investments and loans entities of the national economy, as well as their savings invested in the banking sector, also sent to external borrowing. Desired results are achieved by varying the input to the model input data and control parameters, including

- values, tax rates, levels of direct costs, the number of jobs in the manufacturing and the service sector, average wages, inflation rates, sizes of fixed assets n the beginning of the simulation,

- profitability ratios, wages, income distribution, income-entities of the national economy in the banking sector, the distribution of investments earmarked for investments in fixed assets and working capital for production and consumption, interest rates on loans,

- taxes from export revenues in the budget on consumption, as well as deferred savings.

depreciation rate, and the second output distribution unit savings is connected to the fifth input of the unit simulation of external borrowings and is intended to provide input part of the profits allocated to the repayment of foreign loans, the third output distribution unit savings is connected to the sixth input of the simulation NR is snih borrowing and is intended to provide input savings posted in financial and credit institutions, the fourth output distribution unit accumulations connected with the second input of the simulation the value of fixed assets and is intended to provide depreciation, and the fifth output distribution unit savings is the system output, determining the value of the savings of the subjects of society, the third input unit of modeling the value of fixed assets is the input of the system and is intended to provide input to the initial value of fixed assets, and the output of the modelling unit cost of fixed assets is the system output, determining the value of assets, the first input unit of modeling the value of fixed assets is connected with the fourth output of block modeling of external borrowings and is intended for the input of the share of external borrowings allocated for the reconstruction and expansion of fixed assets, the first input unit of modeling external borrowing is the input of the system and is intended to provide input total current investments, the second input unit of modeling external borrowing is the input of the system and is intended to provide input weighted average interest rate on external borrowings, the third input of the block modeling of external borrowing is the entrance of the m system and is designed for correction of parameters in the block modeling of external borrowing, and the fifth output modeling block external borrowing is intended for the system parameters that determine the debt on external debt, while in the block modeling of distribution coefficients based on the input correction data received at the first input of this block, the output block modeling of the distribution coefficients are profitability ratios, consumption, working capital reserve, the coefficient of the share of profits allocated to the repayment of debt on external debt, the ratio of the invested shares accumulation determined from statistical data, the ratio of wages in the block modeling full production costs and taxes based on the input data received from the sixth output unit modeling of the distribution coefficients of the twelfth unit of the simulation of the full cost of production and taxes on output unit are formed of the value of total production costs, deductions from payroll on savings, and the amount of taxes allocated to the inputs of block modeling of consumption, in the computing unit sales based on the input data, such as total production costs, profit margins, at the output of the computing unit sales is calculated volume of sales in the meadow, and the total profit, in the block of profit distribution based on the input data, such as income, the tax rate on income and consumption ratio, calculated output unit profit distribution, namely, profit, sent respectively from the second output unit profit distribution at the fourth input unit modeling of consumption that is intended to provide input data on consumption and accumulation, and directed to the third output unit profit distribution at the third entrance of the modelling unit of the consumption tax, the distribution unit savings based on the input data, such as income allocated to accumulation, distribution coefficients, such as the ratio of working capital reserve, the coefficient of the share of profits allocated to debt repayments on external borrowing, the ratio of the invested shares accumulation determined from statistical data, the portion of the net salary allocated for accumulation, rate of depreciation, are formed in the output distribution unit accumulations, namely, the portion of profit allocated to production as a working capital reserve, part of the profit allocated for the repayment of external borrowings, depreciation, the welfare indicator is the total accumulation of the population in the block simulated the I value of fixed assets based on the input data, such as depreciation, the initial cost of fixed assets, the share of external borrowing allocated for the reconstruction and expansion of fixed assets, forming the output of block modeling the value of fixed assets, determining the value of assets, in block modeling of external borrowing on the basis of input data, such as the share of external borrowing allocated for the reconstruction and expansion of fixed assets, weighted average interest rate on external borrowings, part of the profit allocated for the repayment of external borrowings, statistically determined correction factors, the current interest rate on external borrowings, calculated such output, as the share of external borrowing, allocated for the reconstruction and expansion of fixed assets, external borrowings for working capital to increase the full cost of production, procurement of goods and performance of services, payable on external borrowings, the output of block modeling consumption based on the input data is formed aggregate demand, the unit of analysis of aggregate demand and supply and control based on the input data, namely, aggregate demand and volume of sales generated output, such as absolute and relative difference IU the control of aggregate demand and supply for the organization of a new cycle of the simulation.
