In the context of climate change and the reduction in CO2 emissions from fossil fuel combustion, the integration of CO2 capture technologies in steam power plants is a key solution. The aim of this study was to analyze the use of ammonia, at different mass concentrations, in capturing post-combustion CO2 in a coal-fired power station and comparing it with the reference 30% MEA case. In this regard, a multi-criteria model was developed to establish the optimal solvent used, considering the least impact on technical performance, economic, and environmental indicators. As a result, the lowest CO2 capture cost was obtained for the CO2 capture process based on 7% NH3, with 59.07 €/tCO2. Integration of the CO2 capture process is more economically viable when the CO2 emissions tax is higher than 70 €/tCO2 for 7% NH3 and 15% NH3, 80 €/tCO2 for 5% NH3 and 30% MEA, and 90 €/tCO2 for 2% NH3. Regarding the overall efficiency, the energy penalty associated with the CO2 capture process integration varied between 15 and 35%, and the lowest value was obtained for 15% NH3. The GWP indicator ranged between 113 and 149 kg_CO2_eq/MWh for NH3 compared to MEA 133 kg_CO2_eq/MWh and the case with no CO2 capture was 823 kg_CO2_eq/MWh.

This article presents the results of an investigation for a new method to form sets of construction machinery. The model for optimizing the set of construction machinery implies the possibility to consider the following: the influence of the quality of operation onto the technical state of the machinery, which is characterized by the readiness factor; costs and reliability of the purchased equipment, new and the used one; influence of capital overhauls; selling machinery and purchasing new one at a higher price; decommissioning old equipment; accompanying economical losses, which is a concealed form of insuring against insufficient reliability of the equipment; optimizing the service life along several criteria – minimum investment, maximum profit, specified level of reliability, period of repayment. This method for optimizing the age structure of the construction machinery set is based on using the method of linear programming. Practical recommendations are also included.

The present paper is aimed at evaluating the methods used for determining the performance of Diesel locomotives. Therefore, two main approaches to assessing the locomotive performance can be distinguished: a method based on individual indicators; a method based on an integrated indicator. The analysis of the available methods for complex evaluation of the locomotive condition has shown that overall performance of the locomotive can be described by a dimensionless indicator. In determining the state of Diesel locomotives, researchers rely on the criteria commonly used in assessing the performance of any machine. They are as follows: technical, economical, functional (operational).

Infiltration systems are frequently used as an option to manage urban storm drainage. By reducing flows and volumes in downstream sewers or in surface waters, they decrease the overflows and make it possible to recharge groundwater. They come in various forms with different uses; therefore, their performance is diverse and integrates multiple aspects. Consequently, a multicriteria approach was developed in order to quantify the performance of these systems and to help in decision making problems. For that purpose, a list of performance indicators integrating technical, economical, environmental and social aspects was developed. The performances were defined with the help of a working group composed of engineers from different technical or strategic departments from Greater Lyon and researchers from different fields. The paper presents the last version of the performance indicators tested according to a set of quality requirements: availability of data, relevance, fidelity, precision, sensitivity/robustness. This critical review of the set of indicators has led us to redefine a certain number of indicators, identify numerous biases and allow putting forward general instructions for criterion or indicator construction. The last phase is to propose multicriteria decision aid methods; a procedure using ELECTRE methods should be used.

Equity risk premium contains the property of reflecting the fundamental judgments of individuals regarding risk that might exists in the economic market and the price associated with that risk. For ERP forecasting, attention is also devoted to technical indicators apart from the macro-economic variables. A set of 14 technical and 14 macro-economic variables is selected for this purpose and based on a standard predictive regression framework; all forecasts are generated by regressing ERP on a constant and a lag of macro-economic or technical indicator. It is found that as compared to macro-economic variables technical indicators provide better indications about ERP estimates. By using National Bureau of Economic Research (NBER) data of business cycle expansion and recessions, relative strength of ERP predictability is also investigated and it is found more than twice for recessions as compare to expansions.

In order to analyse long-term transformation pathways, energy system models generally focus on economical and technical characteristics. However, these models usually do not consider sustainability aspects such as environmental impacts. In contrast, life cycle assessment enables an extensive estimate of those impacts. Due to these complementary characteristics, the combination of energy system models and life cycle assessment thus allows comprehensive environmental sustainability assessments of technically and economically feasible energy system transformation pathways. We introduce FRITS, a FRamework for the assessment of environmental Impacts of Transformation Scenarios. FRITS links bottom-up energy system models with life cycle impact assessment indicators and quantifies the environmental impacts of transformation strategies of the entire energy system (power, heat, transport) over the transition period. We apply the framework to conduct an environmental assessment of multi-sectoral energy scenarios for Germany. Here, a ‘Target’ scenario reaching 80% reduction of energy-related direct CO2 emissions is compared with a ‘Reference’ scenario describing a less ambitious transformation pathway. The results show that compared to 2015 and the ‘Reference’ scenario, the ‘Target’ scenario performs better for most life cycle impact assessment indicators. However, the impacts of resource consumption and land use increase for the ‘Target’ scenario. These impacts are mainly caused by road passenger transport and biomass conversion.

The study evaluates the economic feasibility of technical analysis in the Indian stock market. It discusses that technical indicators do not outperform Simple Buy and Hold strategy on net return basis for individual stocks. Technical indicators seem to do better during market upturns compared to market downturns. However, technical based trading strategies are not feasible vis-à-vis passive strategy irrespective of market cycle conditions. Technical indicators also do not provide economically significant profit for industry as well as economy based data. Combining fundamentals with technical information, we find, that technical indicators are more profitable for small stocks compared to big stocks and for high value stocks compared to low value stocks. However, the economic feasibility of fundamentals' based technical strategies is still questionable. Our results seem to confirm with the efficient market hypothesis.

Subject. The article analyzes development trends in certain types of service robots, namely, hybrid UAVs, bionic prosthetic hands, robotic vacuum cleaners. Objectives. We focus on identifying the main trends in the development of certain types of service robots, building dynamic models of their technical indicators and models of dependence of their price and weight on absolute characteristics and technical parameters. Methods. The study employs methods of correlation and multiple regression analysis. The data of the IFR, the Remotely Piloted Aircraft System, and websites of robot manufacturers serve as the informational basis of the paper. Results. The modeling unveils positive correlation between the integrated indicator of the technical level of hybrid UAVs of convertiplane type and the wingspan. The analysis of modern bionic prosthetic hands shows that the developers focus on optimizing the structure of the prosthetic, however, as the functions of the hand improve, the weight of bionic hand increases. The main factors influencing the price of robot vacuum cleaners are their power, weight, and operating hours. Conclusions. The unit price of a complex indicator of the technical level of hybrid UAVs is lower than the corresponding indicator of fixed-wing UAVs, reflecting a greater efficiency of hybrid UAVs. The analysis of technical indicators of robotic prosthetics (using the case of bionic hands) shows that any improvement of functional characteristics leads to deterioration of weight. The analysis of technical and economic indicators of robotic vacuum cleaners reveals a positive correlation between the price and weight, operating hours and power.

Performance assessment (PA) of urban infrastructure services, mainly in the case of water systems, is becoming a major issue worldwide. Therefore, in the last decade, the need for a clear definition of management objectives of water services and the subsequent need to monitor goals achievement have led to the development of some initiatives to tackle the evaluation of the efficiency of those services, their main aim being the definition of systems of performance indicators. However, these PA systems are strongly oriented by a management/economic perspective and technical aspects have often been ignored. In addition, none of them has specifically addressed the drinking water treatment. This paper presents a proposal for a PI system that applies to drinking water treatment facilities as a part of a standardised methodology for performance assessment. In total, ca. 80 PI have been defined and classified according to seven evaluation domains, namely: treated water quality; plant reliability; use of natural resources and raw materials; by-products management; safety; human resources; and, economical and financial resources.

A mathematical model for the forecasting of the basic metallurgical properties of coke depending on the quality indicators of coals and carbonization parameters is developed. The base of the model are the theoretical and statistical dependences of the physico-chemical and petrographic properties of initial coals on the reactivity and mechanical strength of the coke. These indicators depend on diffusion processes during carbonization. On the basis of initial data, the material and heat balance of the coking process are made and the product price is calculated. The full-function program includes: the initial database interactively formed on the basis of the coals quality certificates and concentrates; the calculating unit of forecasting of the coke properties, allowing to fulfil the mathematical model adapting for the concrete industrial conditions of carbonization process; the unit to calculate results. The calculated values, i.e. the Coke Reactivity Index (CRI) and the Coke Strength after Reaction (CSR) can be used further for technical and economical calculations in the balance logic-statistic model of the blast furnace smelting operation. Or using the feedback, it is possible to calculate necessary relations of the burden components for the carbonization.

Anticipating and analyzing the stock market and the price movement is a challenging task as the nature of the stock prices is quite complicated, non-linear and dynamic. Examining the financial time series data and making decisions is the toughest job in stock market. These correct decisions help in improving the returns on investment and minimize the loss and risks incurred. Technical analysis has been a trading tool since the 18th century which is used by investors and traders to evaluate the investments, identify the trading opportunities and forecast the future stock prices movement by analyzing price trends, chart patterns and volume data. Many different statistical tools are available for the investors and traders for making decision in financial market and analyze the stocks intrinsic value on the basis of fundamentals like balance sheet, revenues, industry trends, economic indicators and consumer behavior. Technical analysis helps the traders and investors predict the market situations and build the gap between market price and intrinsic value of the stocks by applying the techniques of behavioural economics and statistics. Many technical indicators like Simple Moving Averages, Weighted Moving Average, Trend Indictors, Momentum indicators like Stochastic, Relative Strength Index, Commodity Channel Index and Volatility indicators like the Bollinger Bands, Average True Range and Volume indicators are commonly available to study the stock price movement. In this project, the importance and the application of market indicators for technical analysis in predicting stock price movement of large-cap, mid-cap and small-cap companies on BSE is researched.

The purpose of the research of this scientific work is to assess the possibilities of development of farms in modern conditions, as well as to find out the problems and prospects of farms in Ukraine. Method. Farming is a form of entrepreneurial activity of citizens with or without the creation of a legal entity who have expressed a desire to produce marketable agricultural products, process and sell them in order to make a profit on land provided for family farming. An important role in the production of agricultural products is now given to farms that have actually become full-fledged entities in the agrarian diversified economy, have passed their first stage of formation and formation. The presence of a large number of large producers, problems of organization and location of wholesale markets, insufficient population of rural areas, inadequate level of resource supply – all this determines the specifics of the competitive environment in which farms operate. The task of development of farms in Ukraine requires the study of the peculiarities of their activities, analysis of the current stage of functioning of farms, identifying obstacles to their development and outlining areas for improvement of their activities. This is what determines the relevance of this article. Results. The scales and tendencies of development of farms in Ukraine, their place among other agricultural producers, including in the context of regions of Ukraine are analyzed. The main indicators of their activity are described. It is confirmed that despite the large number of farms, their place in the agricultural economy of Ukraine still remains insignificant. The main organizational and economic problems of farm development in Ukraine have been identified, which are related to the lack of equity, conditions for free access to credit, as well as the inadequate ratio between prices for technical equipment and agricultural products. The position of farms in the world is revealed. Scientific novelty and practical significance. The development of farming as a priority form of agricultural farms is shown. A number of measures for the development of farms are proposed. The advantages of farms over personal farms and over agricultural enterprises are given. Problems and prospects of farming in Ukraine are revealed.

In 2019 Technical regulations of the Eurasian economical Union “On the safety of the bottled water, including natural mineral water” TR EAES 044/201 entered into force. These regulations established strict requirements to the indicators of the radiation safety for the bottled water, including natural mineral water. Application of these requirements in practice of the sanitary service led to the ban of the use of the bottled medical-table natural mineral water from the Zheleznovodsk site (Stavropolskiy krai), exploited from the well 69-bis by the criteria of the radiation safety. This study proposes possible solutions to the problem of the regulation of the natural mineral water by the radiation factor, complying to the existing requirements on the radiation safety as well as the proposals of the Institute of Radiation Hygiene on the changes in the Technical regulation TR EAES 044/201 and introduction of the requirements on the radiation safety of the natural mineral water in the legislation of the Russian Federation.

Energy systems should be analysed according to principles of sustainable development. The optimality of technical systems usually is evaluated by only technical and economical criteria. But the estimation of these criteria is not comprehensive enough in the case when system life cycle is much longer than the period of reliable economical prognosis. In this paper the criteria set of energy system evaluation and optimisation was expanded by energy and ecological standpoints and a new multiple criteria indicator (3E factor ‐ Energy, Economy, Ecology) was introduced. The application of this factor was demonstrated by two examples: optimisation of the district heating network pipeline replacement periodicity and optimisation of the thermal insulation of the single family house.

The aim of this study was the development of a model for evaluating dairy cow ration efficiency. This model took into account technical, metabolic, and economic parameters, which were divided into two main categories: input and output. Feeding (food administered and its nutritional characteristics) was considered as the input parameter. The output indicators were directly or indirectly correlated with feeding, and included: quality and quantity of milk, body condition score, live weight, reproductive parameters, incidence of animal diseases (laminitis), undigested fraction, fecal consistency, feed efficiency (FE), and income over feed cost (IOFC). The model was validated using ten dairy farms located in the northwest of Basilicata. The farms were divided into two groups (A and B) as a function of the urea level in bulk milk. In Group A, the urea level was between 25 and 31 mg/100 mL milk, whereas, in Group B, the range was 21-22.5 mg/100 mL milk. The model showed that the values of reproductive parameters were worse in Group A than in Group B. However, the Group A showed better milk qualitative and quantitative characteristics, such as a high average production per head (28.15 vs 26.93 kg), and a high fat (3.92 vs 3.71%) and protein (3.53 vs 3.37%) content of bulk milk. Moreover, the highest values of FE (1.45 vs 1.35 kg milk/kg dry matter) and IOFC (6.07 vs 5.32 €) were found in Group A. The model clearly showed that the administration of unbalanced rations, based on the physiological stage of the animals, negatively affected both the qualitative and quantitative characteristics of milk, as well as the reproductive performances. The administration of unbalanced rations for the energy/protein content caused dysmetabolic syndromes, which led to a reduction of both FE and IOFC. This, ultimately, caused a fall in the overall farm profitability.

Shale gas resources can supply the substantial growing demand for clean energy. In comparison with conventional reservoirs, shale gas reservoirs have lower production potential, and selecting the most favorable areas from the broad region of shale gas prospect is very crucial in commercial development. These areas are screened regarding some key evaluation indicators that affect the ultimate recovery of shale gas reservoirs. Many attempts have been made to screen sweet spots by applying the different evaluation indicators. These studies mainly focus on geological sweet spot identification without considering the economic indicators that may influence the order of geological sweet spots for development. The current study introduces a methodology for selecting the best techno-economic spots in undeveloped shale gas regions by integrating the technical and economic criteria. The techno-economic areas are defined as the geological sweet spots with the highest rate of return under the currently employed technology. The economic objective functions for selecting these areas are net present value, internal rate of return, and payback time. To estimate the unknown features for integrating the technical and economic criteria in undeveloped areas, an analogy study is applied. Due to the large number of unknowns and uncertainties in shale gas evaluation and low confidence of deterministic results, a probabilistic approach is used. As the first attempt in shale gas assessment in Iran, the Lurestan shale gas region is evaluated by applying this approach. The results indicate that no selected geological sweet spots in this region are commercial regarding the current cost rates and the available technology in Iran, and it can be considered as a future affordable source of energy.

Technically sound standards of time and production standards are designed to improve production efficiency, technical and economic indicators of construction enterprises, timely commissioning of buildings and structures being erected, as well as ensuring the proper organization of workers' wages. Labor standards are used in determining the need for construction machinery and equipment, the required number of workers, and also serve as the basis for the development of network and calendar schedules that are part of the project of construction organization (PCO) and the project of construction production (PCP). Standards of time and standards for the production of most of the construction work are contained in the collections of common norms and rates and state elemental estimated norms. However, in the conditions of continuous development and introduction of new production technologies, there is a need to update and refine the existing technical regulation database. Standards of time, corresponding to the modern level of technical development and reflecting the advanced experience of workers, allow to make the right choice when analyzing the most economical ways of producing work. Definition and removal of production standards is to determine the weighted average number of working hours to perform a particular technological operation, while taking into account the conditions of production of this workflow, the numerical and qualification composition of workers.

Solving the housing problem for urban low-income people is one of important issues of the housing policy and urban planning in China. Shanty towns which were left from old days are now the main housing source for low-income populations; therefore, shanty town reconstruction has been taken as a resolution for solving housing problems for low-income people. However, the current land policy, real estate development policy, urban planning laws and regulations are insufficient in solving the shanty town reconstruction difficulties and more likely become barriers of it. A number of indicators such as building density, per capita living space, land prices and floor area ratio are used to determine how successful the shanty town reconstruction being implemented. In this article, a flexible solution on political and regulatory basis for solving shanty town reconstruction difficulties will be proposed by systematically analyzing various economical and technical indicators.

Introduction. Professional construction customers (investors) often face the problem of selecting a reliable contractor, when they have to assess construction companies for potential involvement in their projects guided, among other things, by a directly non-measurable emergent indicator of sustainability (from now on referred to as sustainability of a construction company). The given problem is of particular concern as most construction companies are now financially unstable. Materials and methods. The article defines the sustainability of a construction company. It also evaluates the sustainability of a construction company indicator by a number of statistical estimate iterations. The study proposes an evaluation method for quantitative integrated synthetic aggregators of sustainability of a construction company and identifies several private indicators Xj characterizing a construction company’s stable condition. Results. The advantages of the proposed evaluation method for the sustainability of a construction company are as follows: a unified information basis (construction operations indicators) for the assessment of qualitative and quantitative integrated synthetic aggregators of sustainability. This method is based on unified evaluation indicators of construction operations: technical, technological, organizational, and economical. The proposed method has an advantage of the versatility of the resultant own and comparative assessments of the sustainability of construction companies, visual clarity of obtained results, and relative ease of calculation procedures. Conclusions. This study illustrates a procedure developed for evaluating quantitative indicators of the sustainability of a construction company. This procedure offers a high level of accuracy in determining the reasons contributing to the lower sustainability of a construction company and identifying symptoms indicative of loss of sustainability. An integral indicator is formed that assesses the stability of the construction company according to the results of statistical analysis and represents a weighted sum of the values of the initial indicators of construction operations and activities of the enterprise. In this way, businesses can assess both their own condition and the condition of proposed contractors.

Purpose The purpose of this paper is to introduce an approach to evaluate the establishment requirements of an flight training organization (FTO) through indicators that are not included in the regulations from the viewpoint of “acquired indicators from FTO experience” (AIs-FTOE). Design/methodology/approach Although the establishment requirements of an FTO can be determined through regulations, it was realized that the pilot training process can be achieved in a safe, sustainable and economical manner through indicators that are not included in the regulations. These indicators were obtained through experience in the operation process of the FTOs. In this study, the indicators (obtained from the regulations and experiences) affecting the efficiency of FTOs, that were or would be operational, were determined, and the effects of the indicators on the organization were examined and presented in detail. The case study was carried out in the Department of Flight Training (ETU-P) of Eskişehir Technical University which has an FTO. Findings In accordance with the results, the necessity indicators were defined, and the indicators that were not included in the regulations were called as AIs-FTOE. Identified AIs-FTOEs were classified into three main headings: natural and artificial obstacles, meteorological conditions and physical and technological resources. Detailed indicator data results were presented after examinations. Practical implications When literature on FTOs was examined, it was seen that there is a need to identify and classify indicators that affect the efficiency of FTOs. To the authors’ knowledge, this study will be the first in the literature that presented information based on an active FTO in detail. Thus, the AIs-FTOEs identified in this study will serve as a roadmap for the FTOs to be established and are to be used as parameters to evaluate efficiency for the established ones. Originality/value To the best of authors’ knowledge, this paper will be the first paper in the literature describing the indicators that can be evaluated in terms of efficiency, sustainability and economy of FTOs.

The starting stage of the tender procedures in Russia with the participation of foreign suppliers dictates the feasibility of the developments for economical methods directed to comparison of technical solutions on the construction field. The article describes the example of practical Life Cycle Cost (LCC) evaluations under respect of Present Value (PV) determination. These create a possibility for investor to estimate long-term projects (indicated as 25 years) as commercially profitable, taking into account inflation rate, interest rate, real discount rate (indicated as 5 %). For economic analysis air-blower station of WWTP was selected as a significant energy consumer. Technical variants for the comparison of blower types are: 1 - multistage without control, 2 - multistage with VFD control, 3 - single stage double vane control. The result of LCC estimation shows the last variant as most attractive or cost-effective for investments with economy of 17,2 % (variant 1) and 21,0 % (variant 2) under adopted duty conditions and evaluations of capital costs (Cic + Cin) with annual expenditure related (Ce+Co+Cm). The adopted duty conditions include daily and seasonal fluctuations of air flow. This was the reason for the adopted energy consumption as, kW∙h: 2158 (variant 1),1743...2201 (variant 2), 1058...1951 (variant 3). The article refers to Europump guide tables in order to simplify sophisticated factors search (Cp /Cn, df), which can be useful for economical analyses in Russia. Example of evaluations connected with energy-efficient solutions is given, but this reference involves the use of materials for the cases with resource savings, such as all types of fuel. In conclusion follows the assent to use LCC indicator jointly with the method of determining discounted cash flows, that will satisfy the investor’s need for interest source due to technical and economical comparisons.

Currently there is no tool to assess the sustainability performance of reuse systems in Australia. This research fulfills that gap by developing a set of sustainability indicators (SIs). A unique methodology was developed based on understanding of the reuse systems, reviewing and examining the issues related to reuse, and Australian policy and guidelines in terms of sustainability. It was established that a sustainable reuse system should be based beyond the triple bottom line approach, and involve consumers in decision making, address institutional issues, and focus on the outcomes rather than the output, with a system approach. Twenty seven SIs were identified under five categories: environmental, technical, social, economical, and institutional. The case studies demonstrated the application of the SIs in sustainability assessment of two reuse systems: (1) tree plantation and (2) lake discharge for augmenting environmental flow. The evaluation was done based on multi criteria decision assessment.

In order to design a comfortable living environment for everyday life, namely it pertains to residential sector of microdistrict, it is necessary to take into account a range of nuances: the number and size of public utility sites and children’s playgrounds, guest parking lots and temporary car storage areas, the number of green spaces and common areas, as well as the number and size of children's educational institutions, shops, cultural and consumer service enterprises and much more. On the other hand, the comparison of different neighborhoods or the dynamics in the development of a single neighborhood requires digital indicators in absolute or relative values. In urban planning the technical and economic indicators of residential development are applied for these purposes. Technical and economic indicators are used for various purposes, including for comparative analysis of the quality of life in a residential area and even the cost of residential units. First and foremost, they are related to the size of the microdistrict and the number of residents. Some of them depend on these indicators, for example the density of residential buildings; some affect them, for example, the number of storeys affects the density of housing and density of residents; other indicators depend on the key technical and economic indicators, such as a number of parking lots, green spaces, and size of playgrounds.

Abstract Investigating the performance and productivity level of different energy consuming sectors in all countries is an inevitable action. This procedure will be conducted by comparing the energy input and the output of the system which is vital to ensure that the system is used properly. The proper utilization of systems will lead to more efficiency in the energy consumption section. One of the most important tasks in this type of study is the analysis of uncertainty indicators. The analysis and evaluation of uncertainty indices in energy consumption system is a tool that prioritizes the indicators in terms of importance and impact on each of the consumption targets. These consumption goals include energy, environmental, technical, economical, and social objectives. Ultimately, the output data of the uncertainty analysis will be very helpful for making the system more reliable and usable. In this study, we first introduced different sectors of the energy consumption system in Finland and examined each of these sectors in terms of physical and environmental goals. Then the uncertainty indexes in different sectors are extracted, evaluated qualitatively and quantified using the fuzzy logic method. Finally, indicators are prioritized based on the level of effectiveness and uncertainty. According to the results of this research, among 44 considered indices, the security of energy supply, carbon emission, equivalent annual cost, reliability, and political acceptability are respectively the most important indices for energy, environmental, economic, technical and social goals.

AbstractThis paper is concerned with early cost estimation of sport facilities. Sufficiently precise cost estimation is essential for investors in the pre-investment stage where they decide on whether to pursue an investment and choose a suitable technical solution for the development of the project. Through a detailed analysis of the technical and economic documentation pertaining to seven sport facilities projects assembled using concrete prefabricated beam parts, as well as evaluation of the data thus obtained, three types of technical-economic indicators were set in relation to the enclosed building area, the number of spectator seats and the sports playing area. The results achieved indicate that evaluation of relations between these three indicators could contribute to a more effective use of investment funding on the part of the investor. Other conclusions include the finding that available indicators published by private companies active in the area of construction budgeting are not sufficiently accurate for the purposes of investment decision-making; specifically, these indicators greatly overestimate the costs of sport facilities, which can potentially lead to these projects being rejected. This contribution brings know-how for a more accurate early cost estimation of sport facilities in the Czech Republic which can, thanks to a generally applicable methodology, be used in other countries as well.

The technical and technological requirements to the system of machines are given now only for certain groups of technical means, which does not reflect the values and development of the entire system. The paper deals with the basic general requirements to the system, including aspects of technological and technical basis for sustainable food and raw materials supply for Russia's economic security and formation of technical policy. The system of basic technologies is defined; it should consist of a set of machine process modules that are necessary for the implementation of the entire set of operations of agricultural production. It is found that a promising range of machinery must contain technologically, technically and economically optimal set of standard series, including their constituent equipment with indication of modifications and models in production, united by common economic purpose and complete production technology. It is noted that the developed ranges of the technical means should comply with the progressive innovation trends of scientific and technical and technological progress. It is proposed to put into operation the systematized basic requirements for all main types of agricultural machinery. They should reflect the typical basic indicators for each type of machine. It is found that certain standard sizes of technical means require to cite only those indicators by which they differ from the basic model. The paper summarizes the requirements to the technical and economic efficiency of the system of technology and machinery with highlighting the innovations in the system.
