The tests performed by the authors have shown that diesel locomotive engines efficiently operate using a mixture of diesel oil and about 40% of rapeseed oil methyl ester (RME) while their ecological and economical parameters do not differ much from those of the locomotives operating on pure diesel oil. When biodiesel is used, the pollutants released into the atmosphere by an engine are less harmful. Therefore, the respective laws of the Republic of Lithuania provide for some financial incentives and allowances to transport enterprises using biological diesel oil. The paper presents a mathematical model for determining the expenses associated with the use of biological diesel oil.

The number of various transport facilities used in Europe is rapidly growing. They release a big amount of pollutants into the atmosphere. Therefore, environment protection from these pollutants ejected by internal combustion engines is a key problem facing us today and which will be acute in the future. Biofuel is the only effective and widely used alternative fuel which can reduce pollution of the environment. The main aim of the present paper is to perform a comparative analysis of burnt gases of engines using rapeseed oil methyl ester and petroleum diesel oil and to determine ecological effectiveness of biofuel used in diesel locomotive engines in railway transport.

The article analyzes the modern model for evaluating the improvement of investment activity efficiency and provides conclusions on the level of development of the current state of railway transport in the Republic of Uzbekistan. The economic effect of intensive investments is the equivalent of the costs and benefits of the difference between the result and the costs of achieving it. The economic efficiency of intensive investments is defined as the ratio of investment costs to achieving a profitable result (economic effect). The indicators characterizing the economic efficiency of intensive investments: the integrated effect, the need for additional financing, the internal rate of return, the intensive return on investment ratio, the intensive return on investment index, the innovation ratio, investment in human resources, and the effectiveness of modern corporate governance. will be included. The multiplier effect in which a set of multipliers reflects changes in production volumes, investments and industry characteristics. Analysis of specific activities shows the impact of growth indicators, given its contribution to the dynamics of the economy. An increase in investment costs will lead to an increase in production and income. This interaction is explained by the multiplier effect. The concept of the multiplier means "multiplier". The essence of the multiplier effect is that an increase in investment will lead to greater growth in national income.

This paper calculates the production costs of turnip rapeseed oil-methyl-ester (RME) as a substitute for diesel fuel. Theoretical farm models, which assume that compulsory fallowing area might be used for cultivating turnip rapeseed, provide the estimated short term production costs. The necessary government support for producing RME is calculated based on the difference between the production costs of RME against the taxfree wholesale price for diesel oil. In 1990 prices, a producer price of 1.70FIM/kg for turnip rapeseed means production costs of RME are approximately 4.28 FIM/1, or five and a half times higher than the taxfree wholesale price of diesel oil. When the realized producer price in 1990 of 4.12 FIM/kg is used, the RME production costs are 9.98 FIM/1. Thus, there is no economic basis for RME production in Finland.

Current geopolitical and economic conditions for the functioning of railway transport in most post-Soviet states are such that it is extremely difficult to provide required quality of transport services and break-even operations at high expenses for maintaining the railway infrastructure and rolling stock. Dynamics of transportation of the Tajik Railway (TSR) is shown, which displays that most of its sections are classified as low-intensity ones. The paper proposes methodical principles, setting and qualitative analysis of the task of rationalization of operational work and organization of car flows for international transportation, taking into account the specifics of the Tajik Railway. There is a problem of complex maintenance of the efficiency of operational work in modern conditions based on the synthesis of the tasks of self-management (rational internal operational technology of the Tajik Railway) and coordination tasks (technological interaction with railway administrations of other states). Author substantiated the necessity of solving this problem. Proposed classification of technological restrictions and controlled variables in the performance of transport takes into account methods for changing external conditions for the functioning of the railway landfill and methods for increasing internal efficiency of its operation. The search for the solution of the problem involves direct search of variants along its ordered set with clipping of groups of variants that do not correspond to constraints, with the subsequent finding of compromise control over a set of effective alternatives.

The paper attempts to estimate, in monetary terms, the volume of free digital services in GDP while assessing the contribution of digitalization to changes in welfare and economic growth. Approaches to such an estimation are analyzed and criticized. In particular, the calculation of the added value created in the digital sector does not properly reflect the economic effect of digitalization. Alternative auxiliary methods for estimating the contribution of digitalization to GDP growth are considered: the creation of satellite accounts of the digital economy within the SNA; the categorization and calculation of “purely” digital goods. The paper analyzes the methodology of calculating GDP which takes into account consumer surpluses from the use of free digital goods. The advantages of this methodology are outlined, including the consideration of a significant part of the digital sector of the economy in the calculation of GDP, as well as the relative ease of its use. This methodology was tested by drawing on the example of the Republic of Bashkortostan.

AbstractThis paper presents the logistic system of fuel life cycle, covering diesel oil and the mixture of rapeseed oil and butanol (2:3 ratio), using the Life-Cycle Assessment (LCA) method. This method is a technique in the field of management processes with a view to assessing the potential environmental hazards. Our intention was to compare the energy consumption needed to produce each of the test fuels and emissions of selected substances generated during ithe production process. The study involved 10,000 liters of diesel and the same amount of rapeseed oil and butanol mixture (2:3 ratio). On the basis of measurements the following results were obtained. To produce a functional unit of diesel oil (i.e. 10,000 liters) it is necessary to extract 58.8 m3 of crude oil. The entire life cycle covering the consumption of 10,000 liters of diesel consumes 475.668 GJ of energy and causes the emission to air of the following substances: 235.376 kg of COx, 944.921 kg of NOx, 83.287 kg of SOx. In the ease of a functional unit, to produce a mixture of rapeseed oil and butanol (2:3 ratio) 10,000 kg of rapeseed and 20,350 kg of straw should be used. The entire life cycle of 10,000 liters of a mixture of rapeseed oil and butyl alcohol (2:3 ratio) absorbs 370.616 GJ of energy, while emitting the following air pollutants: 105.14832 kg of COx, 920.03124 kg of NOx, 0.162 kg of SOx. Analysis of the results leads to the conclusion that it is oil refining which is the most energy-intensive and polluting process in the life cycle of diesel. The process consumes 41.4 GJ of energy, and causes a significant emission of sulfur oxides (50 kg). In the production of fuel that is a mixture of rapeseed oil and butyl alcohol (2:3 ratio), rape production is the most energy-intensive manufacturing process is (absorbs 53.856 GJ of energy). This is due to the long operation time of the farm tractor and combine harvester. The operation of these machines leads also to the emission of a significant amount of pollution in the form of COx (2.664 kg) and NOx (23.31 kg).

Introduction. The development of the tourism industry significantly affects the development of the country's economy as a whole. Its role is determined not only in the financial contribution, but also in stimulating other related industries that perform both ancillary and independent functions. The modern Ukrainian tourist market is undergoing many changes, so one of the current problems today is the use of effective tools for finding and systematizing the necessary information to forecast the development of the tourism industry. The purpose of the paper is to define the concept of monitoring the tourism industry as a means of improving the efficiency of state regulation of the economy, proving the importance of monitoring research, identifying problems of monitoring and ways to solve them. Results. The main purpose of tourism monitoring is to assess and forecast the state of tourism. Tourist services are localized and specialize in meeting the socio-economic needs of the population directly at the municipal level and are one of the main sources of funds coming to the state budget and ensure the reproduction of social infrastructure. In order to analyze trends in tourism and tourism in Ukraine, as well as assess the socio-economic effect of the implementation of measures of state support for domestic and inbound tourism, the central executive bodies of state regions of Ukraine, carrying out executive and administrative activities in tourism, the state of the tourism industry is being monitored. Given the large recreational and tourist potential in Ukraine, there is no full-fledged system of monitoring the market of tourist services by the state. This is due to the lack of an independent executive body in the field of tourism, endowed with certain powers, and a single system of statistical indicators of the market of tourist services. Modern statistics, both at the state and regional levels, do not give a complete picture of the state of tourism. Monitoring of tourist resources, objects of the tourist industry should give a clear picture of interaction of various branches of economy of the republic for the purposes of a complex estimation of directions of improvement and efficiency of functioning of the connected branches, exclusion of interbranch disproportions which negatively affect general development. Conclusion. To increase the growth rate of the tourism industry, the formation of a positive tourist image of the region, increase its visibility requires constant monitoring of the state and development of the tourism market. Monitoring will allow tracking the trends of the tourism market in the dynamics and promptly make changes to the developed programs and plans for the development of the tourism industry, develop recommendations for their adjustment, increase the effectiveness of tourism management.
