Tariffs for energy and energy resources are the main factors determining the sustainable development of the economy. The aim of the paper is to determine and compare the dynamics evolution of the tariffs for thermal energy and the evolution of the gross domestic product (GDP).The data on the heat consumption and tariff change in the city of Chisinau were examined in monetary terms and in relative units compared to the base year 2009. The higher the tariffs, the more part of the GDP, characterized in the economy by the volume of "Output", is spent on "Intermediate consumption (PP)". The difference between "Output" and "Intermediate consumption" volumes is the "gross added value (VAB)", which is the main component of GDP. The analysis of the changes in the real GDP volume of the Republic of Moldova and the increase of the tariffs for the years 2009-2017 (taking into account the GDP forecast for 2018) show that the increase in the tariffs for thermal energy significantly exceeded the real GDP growth. Considering that the planned GDP growth is 4,7% and taking into account the change in the consumer price index (inflation rate), the calculated reduction of the thermal energy tariff in Chisinau is estimated at 28% compared to the existing value, so to 803 lei / Gcal compared to the currently regulated value of 1122 lei / Gcal. The conclusion was reached on the opportunity of applying the proposed methodology to justify current tariffs and in the near future not only extends to thermal energy tariffs, but also for other types of energy, material resources and services in the field of production and social sphere.

The purpose of this research is to determine the effective way of implementation of the control algorithm, as an important functional part of information and control computer systems. The search criterion is the minimum of internal hardware FPGA resources required for the control unit implementation. This criterion allows miniaturization of dimensions, improves reliability by reducing the number of interconnections inside the chip, and ensures the possibility of a compact arrangement of various system components, which is especially important when using the “system-on-chip” design technology. The control unit holds a prominent place in the digital information and control systems. A comparative analysis of two control unit models represented as a finite state machine with either hard or programmable logic was proposed. Advantages and disadvantages of both models were determined according to the peculiarities of the information and control system algorithms, and, it was proved that the FSM model with a programmable logic matched these peculiarities in a greater degree. The purpose of this study was achieved due to the application of the proposed method for the implementation of the FSM with the programmable logic using the embedded memory of the FPGA and ProASIC chips. The main result was a substantial decrease in the LUT number used. The experimental results were obtained applying the chips of the world's top manufacturers - Xilinx, Altera/Intel, Microsemi. The studies were carried out based on the onboard computing complex control algorithm.

The structure of the economy of the Republic of Moldova was reviewed and the analysis of the main macroeconomic indicators, including the energy sector, was conducted. For a long period, data on the state of Moldova’s energy, technical and economic indicators and development trends have been analyzed. Particular attention is paid to the definition of changes in the value of the real gross domestic product (GDP), taking into account the coefficient of deflation. The quantitative dependence of GDP on the volumes of "Output" and "Intermediate Consumption" is shown. It is revealed that the more “Intermediate Consumption”, the lower the GDP, ceteris paribus. The major share of the cost of the industry sector is covered by “Intermediate Consumption”, which in turn is higher, the higher the tariffs for energy, materials and other services provided by the industries to each other. It was concluded that tariff growth should not overtake real GDP growth over the past few years. The results of the calculations and their analysis show that, in reality, the growth of tariffs is far ahead of the growth of real GDP, which does not contribute to the stable development of the country's economy. It was proposed to revise tariffs, in particular for energy resources, and to bring the rates of their change in line with the growth rates of real GDP. An approach has been formulated for determining the marginal levels of tariffs, based on the condition that their growth rates do not exceed the growth rates of real GDP.
