Item 3D Modeling of Biological Wastewater Treatment in Aeration Tank(Дніпровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпро, 2020) Biliaiev, Mykola M.; Lemesh, Maksym V.; Gunko, Olena Y.; Zadoia, Viacheslav O.; Mashykhina, Polina B.; Yakubovska, Zinaida M.ENG: Purpose. The main purpose of the article is to develop a 3D CFD model for modeling the process of biological wastewater treatment in an aeration tank. Methodology. For mathematical modeling of the process of biological wastewater treatment in the reactor, taking into account the flow hydrodynamics, geometric shape of the aeration tank, convective-diffusion transfer of the substrate and activated sludge, a 3D CFD model was built. The model is based on the three-dimensional equation of motion of an ideal liquid and the equation of mass conservation for the substrate, activated sludge. The field of sewage flow rate in the aeration tank is calculated based on the velocity potential equation. The process of biological transformation of the substrate is calculated on the basis of the Monod model. The splitting scheme was used for numerical integration of the equations of convective-diffusion transfer of activated sludge and substrate. The splitting is carried out in such a way to take into account the transfer of substrate (activated sludge) in only one direction at each step of splitting. The calculation of the unknown value of the substrate (activated sludge) concentration is carried out according to an explicit scheme. The Richardson method is used to numerically integrate the three-dimensional equation for the velocity potential, and the unknown value of the velocity potential is calculated by an explicit formula. Euler's method is used for numerical integration of equations describing the process of substrate transformation and change in activated sludge concentration (Monod model). Findings. The software implementation of the constructed 3D CFD model is carried out. A description of the structure of the developed software package is provided. The results of a computer experiment to study the process of wastewater treatment in an aeration tank with additional elements are presented. Originality. A new multifactor 3D CFD model has been developed, which allows quick assessing the efficiency of biological treatment in an aeration tank. Practical value. The constructed 3D CFD model can be used to analyze the efficiency of the aeration tank under different operating conditions at the stage of sketch design of wastewater treatment systems.Item Analysis of The Influence of Rolling Stock on Infrastructure Facilities as a Factor of Management of the Economic Efficiency of Transport Construction Enterprises(ТОВ «ДКС Центр», Київ, 2023) Kalinichenko, Lyudmila L.; Mishchenko, Maksym I.; Martseniuk, Larysa V.; Bobyl, Volodymyr V.; Pikulina, Olena V.ENG: Purpose.

O.ENG: Methods. To conduct research, the following methods were used: competition, SWOT analysis, mathematical analysis, marketing models, the PEST analysis method, the decision-making method, the Kaizen approach to achieve a high degree of quality of a product or service, as well as systems approach. Results. The article proves the expediency of applying anti-crisis management of passenger transportation as a factor of increasing the competitiveness of the railway. The analysis of the development of the transport services market has shown that rail transport is gradually losing its passengers, in favor of air and road transport. The management of «Ukrzaliznytsia» has recently made many steps to improve the competitiveness of railway passenger transportation in the domestic market of transport services, but these measures are not sufficient today to restore the lost positions that the railway had before. In order to increase the level of competitiveness of railway passenger transportation, as well as to develop a larger segment in the transport services market, the following tasks are identified: to conduct research and analysis of factors affecting the current situation in the service market, to analyze the advantages of existing potential competitors in the transport services market, to analyze the experience of passenger transportation in the European Union, to develop measures that can be proposed to «Ukrzaliznytsia» to improve the efficiency of passenger services and generate additional profit. Novelty. Areas of crisis management to improve the efficiency of passenger transport are proposed, namely: the development of railway tourism, the introduction of a system of discounts «bonus ticket», the creation of a railway hub, implementation of Kaizen approach to achieve a high level of quality services, the organization of multimodal passenger transport by «travel card». Practical value. The implementation of the proposed measures and strategies will allow «Ukrzaliznytsia» to identify promising mechanisms for managing the passenger complex in the context of an escalating crisis. All these measures will help «Ukrzaliznytsia» to get out of the crisis and get additional profit for the passenger industry.Item Comparison of Tourist Traffic by Railway and Automobile Transport and Methodical Approach to Determining the Costs of Such Transportations(НВП ПП «Технологічний Центр», Харків, 2017) Barash, Yuriy S.; Hnennyi, Oleh M.; Martseniuk, Larysa V.; Charkina, Tetiana Yu.ENG: The article aims to systematize the advantages and disadvantages of railway and automobile tourism and develop efficient areas of their use in this context. Moreover, the authors set a goal to develop a methodical approach to determine the costs of the company that will organize transportations on the specific tourist route. Studies have shown that tourist traffic by railway transport has high potential, provided that it will use modern comfortable rolling stock and have in its structure not only the cars for tourist transportation, but also dining car, casino car, disco car (during the day game car for kids) and others. The above mentioned set of cars should be recommended for cruise travel with a period from 8 to 28 days, for shorter journeys the tourist train may not include casino car, disco car (during the day game car for kids) and others. The final choice of tourist traffic should be justified by economic calculations using the method proposed by this article. The approach is based on accounting all complex of costs associated with the technological process of tourism services. It includes the costs for the process of transportation itself, delivery of additional services of infrastructure and rolling stock owners, pay for transfer transportations, services of hotels, restaurants, cafes, travel agencies, advertising organizations and own costs of travel company. It makes possible to determine the costs of travel package more accurately, taking into account the demand for this type of tourist traffic.Item The Concept of Anthropotechnics in the Social and Humanitarian Dimension(Український державний університет науки і технологій, Дніпро, 2024) Bazhan, Serhii ; Chernova, Nataliia S.ENG: Purpose.

The tourism business and the hotel and restaurant sector, which have recently developed greatly, have suffered from extensive losses and bankruptcies, a large number of restaurants and cafes have been closed, and many people have lost their jobs and their income. Even large chains of hotels and restaurants have suffered as well as other businesses. The hotel and restaurant business was the first one that has to adapt quickly to changes caused by the pandemic, to stablish work in new conditions and develop new directions and measures that will take the restaurant business out of the crisis. Given the current need to apply security rules, and the need to comply with quarantine measures, it is necessary to use computer and digital technologies that will help managers to attract new customers and earn extra income. The authors propose to use such tools of crisis management of the restaurant business as: technologicalization, online marketing and influencer – marketing, unique content. These activities are necessary in order to pay new attention to the dishes and services offered by cafes and restaurants. To restart this business in a modern way and with new tendencies, and to adapt to changes in the changing environment and to quarantine measures. To develop additional promotions and offer «economy», «standard» and «luxury» class menu. To organize the fast, high-quality delivery to cafes and restaurants in modern conditions, preferably free, it has become a great necessity and convenience in pandemic conditions; it will attract additional consumers to the restaurant business. In the modern market concept of restaurants in a pandemic, it is necessary considering not only the factors that existed for many years, but also new additional factors in the hotel business, without which it is now impossible to operate this business in a pandemic, it would be safe to provide services, awareness of the service In the modern market concept of restaurants in a pandemic, it is necessary considering not only the factors that existed for many years, but also new additional factors in the hotel business, without which it is now impossible to operate this business in a pandemic, it would be safe to provide services, awareness of the service or product, in the use of digital technology by an institution that wants to get more income and occupy a larger segment in this market of hotel and restaurant business. The authors insist that in modern conditions, it is essential to take into account the laws of competition; because now the consumer chooses a quality product or service at a better price, other goods or services do not attract consumers.Item Directions of Extreme Tourism in Ukraine(Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпропетровськ, 2016) Martseniuk, Larysa V.ENG: Purpose. In the world market of tourist services the extreme tourism is very popular, as it does not require the significant financial costs and enables year on year to increase the offers of holiday packages, associated with active travel. Ukraine has significant potential for the development of extreme kinds of rest, but it is not developed enough. Forms of extreme tourism are unknown for domestic tourists, and therefore, they formed a negative attitude. The aim of the article is the analysis of extreme resort potential of Ukraine and promotion of the development of extreme tourism destinations in the travel market. Theoretical and methodological basis of research is the system analysis of the problems of ensuring the competitiveness of the tourism industry, theoretical principles of economic science in the field of the effectiveness of extreme tourism and management of tourist flows.

Дніпро, 2022) Martseniuk, Larysa V.; Kovalenko-Marchenkova, Yevheniia; Furfaro, Ricardo DanielENG: The authors emphasized that railway transport plays a major role in the life support of Ukraine, especially during the war (because passengers are transported by railway transport not only in the normal mode, but also by evacuation trains; not only scheduled cargo is transported, but also those reoriented from water transport due to the seizure of Ukrainian ports by the russian aggressors; enterprises are transported from the areas under fire to a safer place), so efforts must be made to ensure the smooth functioning of this type of transport both within the country and in interstate communication. In this context, it is highlighted that, in addition to significant technical barriers to crossing borders, Ukraine has non-compliance of the legislation in the field of railway transport with the legislation of the European Union. At the same time, it is noted that with the signing of the Association Agreement with the European Union, the issue of integration into the single European transport space has become acute for Ukraine. This involves the transition to common principles of the operation of the rail transport market, including the presence of independent: railway infrastructure operator, who will be responsible for its quality and capacity (i.e. the number of trains that will be able to move on the tracks); the regulator of railway transport, which will approve the tariff for access to the infrastructure, will ensure equal access to it for all operators of railway transport; the railway safety authority, which will determine the requirements for carriers, check their compliance and issue licenses for transportation. A necessary condition for adaptation to EU legislation on railway transport is the harmonization of Ukrainian legislation with the European one, elimination of differences in the legal framework regulation of railway transport. Harmonization regulatory and legal field of operation of railway transport to the European one, appropriate reforms are needed. The main European Directives and Regulations in the field of railway transport are outlined, according to which it is necessary to amend the Law of Ukraine “On Railway Transport”.Item Economic and Mathematical Models of Development of the Railway Tourism(NTI-UkrSURT, Kharkiv, Ukraine, 2019) Pshinko, Oleksandr M.; Martseniuk, Larysa V.; Bobyl, Volodymyr V.; Kakhovska, OlenaENG: Abstract. The authors used a complex of mathematical models meant for the optimal investment of the processes of creation and use of the railway transport infrastructure. The specific features of these models are as follows: long-term period of realization of the infrastructure projects, many participants with special interests, which do not always coincide, a lot of factors of uncertainty connected with the choice of quantities of the calculation parameters, etc. The authors created economic-mathematical models of the discrete optimal planning of the railway tourism operations. This takes into account conditions of risks and cooperation, and allows to determine sets of effective routes which are most profitable ones, provided they meet the established demands. The latter includes routes which meet maximum criteria of the net costs under the conditions of the established system of demands for the activity of the tourism operators.Item The Economic Guarantee of Logistic Connections Optimization at Railway Transport(Dnipro National University of Railway Transport named after Academician V. Lazaryan, 2019) Kopytko, Vasyl; Dziuba, Sergei; Mìshchenko, Maxym; Shargun, TetyanaEN: Abstract. The efficiency increasing of railway transport functioning is a main factor in the economic growth of the national economy. Material reserves are the main factor that defines the strategy of the enterprise and influences on the economic optimization level of logistic connections in general. Waste on deficiency and expense of storing the taken out from the main turnover material reserves redouble the economic situation. In this research the sources of the arising an uncertainty by taking a decision about economic optimization of logistic connections and working out methods of need determination in conditions of a certain uncertainty that will be led to improvement of the economic effectiveness of activity are determined. The best methods that may be used for this purpose are analysis of temporary series, multiple regression and correlation analysis, pattern recognition. The paper presents the results of research that allow, based on the built neuro-fuzzy model, to evaluate the dependence of macroeconomic indicators of the national economy of Ukraine on the indicators characterizing its economic situation in order to improve the control efficiency of logistics systems. The built neuro-fuzzy model, unlike existing models, allows reproducing the complex nonlinear dependences.Item Economic Prerequisites for Improving the Adaptation Capabilities of Transport Construction Enterprises for Perfectibility Their Productivity(Odessa National Economic University, 2022) Bereza, Ivan V.; Bashmakov, Maksym S.; Chernova, Natalia S.ENG: The article considers current directions for improving the economic condition of transport construction enterprises in the crisis phenomena conditions, both in the transport industry and in the country as a whole. The purpose of article is research and economic substantiation of the possibility of improving the economic condition of transport construction enterprises due to the improvement of their adaptation capabilities, better application of all productive potential to market demands of the transport industry. Research methodology involves the use of methods: empirical research (comparison, observation), theoretical research (ascending from the abstract to the concrete), general scientific methods (abstraction and concretization, analysis and synthesis, induction and deduction, analogy), etc. The relevance of solution to the scientific problem defined in the article is that in conditions of increased requirements for the quality parameters of maintenance and service of transport construction facilities, limited funds for transport construction enterprises, there are requirements for increasing productivity and efficiency of activity. The results of the study are as follows: indicators of monitoring the state of transport construction enterprises, which reflect the market potential of such enterprises, taking into account the requests of the transport industry, in the conditions of harmonization of the key directions of activity of the national economy main branches of Ukraine to the world economic formation, are determined. The originality and practical value of the research lies in the fact that the article systematizes the key performance indicators of transport construction enterprises, which affect their productivity and efficiency. The conclusions of the study are as follows: it is shown that the stabilization of fixed assets technical condition of JSC “Ukrainian Railways” through the reproduction of railway infrastructure will provide an opportunity to ensure the strategic development and effective functioning of railway transport, to ensure the necessary level of throughput and carrying capacity, safety of train traffic, which will ultimately increase competitiveness railway transport and the state’s defense capability.Item Economy, Public Administration and Legal Relations under the Permanent Armed Conflicts: Paradoxes and Regularities of Development(ТОВ Інститут суспільної трансформації, Київ, 2020) Martseniuk, Larysa V.; Cherniak, Nataliia; Tishchenkova, Svitlana; Botvinov, RostislavENG: The paper incorporates a recurrently resonating question: «How does a long-standing armed conflict influence the economy of the warring countries in the contemporary polycentric world where foreign-policy activity of the new «centres of power» acquires somewhat chaotic, unpredictable pattern?» Modern warfare resembles a multi-act theatrical performance with an extremely intricate script and its main actors not present in the scene but rather staying behind the curtains. Regrettably, the human casualties in these confrontations are real. They are a tribute paid to the two aspirations inherent in the humankind - for enrichment and for power. It may look as a paradox but the economy, similar to the nature, demonstrates the capacity for survival in the extreme conditions. In our case, in the conditions of permanent wars being waged for over half a century. On the example of the Israeli-Palestinian and the Indo-Pakistani conflicts, it has been proven that a long-standing inter-state conflict may become a «catalyst» for growth of economic potential or in the least ensure the stability of the development of the state. Despite the fact that both warring «dyads» consist of the players from different «weight categories» (the countries vary considerably by the population size, economic capacity and government spending), we have revealed a multitude of inherent common trends in the development of economy, system of public administration and social relations in general. We conclude that a prolonged state of «turbulence» persisting in the Middle East and South Asia, with every capacity of the economies of the countries for stabilization and development even in the conditions of war, presents a threat to the entire world. Maintaining the stability of systems with the help of destructive measures is the strategy similar to «using the time bomb with undefined impact time and zone».Item Efficiency of Modernization of Wheel-Motor Blocks using Anti-Friction Traction Motor Support Bearings(Дніпропетровський національний університет залізничного транспорту ім. акад. В. Лазаряна, Дніпро, 2018) Kapitsa, Mykhaylo I.; Gnennyi, O. M.; Bobyr, Dmytro V.ENG: Purpose. The use of anti-friction traction motor support bearings (TMSB) instead of plain friction traction motor support bearings is a priority direction of locomotive development both for newly constructed locomotives and for those in operation. The solution of the set tasks for introduction of wheel-motor blocks (WMB) with anti-friction bearings demanded the search for alternative variants and new technical solutions. The purpose of the article is to determine the feasibility of re-equipping the diesel locomotive wheel-motor blocks with anti-friction bearings through the life cycle calculation (LCC). Methodology. The procedure and criteria for assessing the economic efficiency of project (investment) proposals and investment projects approved by the Cabinet of Ministers of Ukraine envisage that the cost-effectiveness analysis of an investment project is carried out according to the following criteria: net present value, internal rate of return, discounted payback period and profitability index. The use of these criteria of economic efficiency fully corresponds to modern principles, theoretical-methodical approaches and world practice in evaluating the efficiency of investments. The evaluation of the technical and economic efficiency of the modernization of the diesel locomotive wheel-motor block is made on the basis of calculation and comparison of the following criteria: the net present value (NPV) of modernization, the internal rate of return (IRR), the profitability index (PI) and the discount payback period. Findings. The results of the calculations of the values of the main criteria show that the innovative project for the modernization of the locomotive provides a high level of economic efficiency. At the same time, the value of the discounted payback period of investments in modernization indicates that it is expedient to carry out this operation if the residual life of the upgraded locomotive of the M62 series is at least 15 months. Originality. Taking into account the specifics of the type of locomotive work in freight traffic, we developed a method to determine the individual components of the average annual economic effect of modernization of the diesel locomotive wheel-motor block, which includes saving of oil costs, repairing and servicing the diesel locomotive wheel-motor unit, as well as change of TMSB brass and saving fuel costs for traction. Practical value. The results of the work make it possible to determine the expediency of modernization of diesel locomotives taking into account the features and conditions of their operation and the specifics of modernization.Item Features of Structural Transformation of Railway Transport Based on the Principles of Marketing Management(North University Centre of Baia Mare, Romania, 2022) Charkina, Tetiana Yu.; Zadoya, Vyacheslav O.ENG: It is established that despite the critical importance of railway transport for the national economy and society, in recent years the railway company has been in a state of deep crisis. It is revealed that the gradual aging and extremely unsatisfactory technical condition of the railway infrastructure and rolling stock level the ability of the railway company to carry out high-quality and safe railway transportation, lead to a gradual loss of customers and the share of railway transport in the market of transport and logistics services, destabilizing the company’s work and reducing the opportunities for its financial and economic recovery and innovative and technical revival. It is proved that in order to ensure innovative growth and competitiveness of railway transport in the market of transport and logistics services, it is necessary to activate the processes of its structural transformation by applying modern effective tools for implementing innovative changes at the enterprise. The processes of reforming the railway industry are investigated and the planned reformation changes and deadlines for their implementation do not correspond to the actual pace of implementation of structural transformations in railway transport. The expediency of structural transformation of railway transport based on the principles of marketing management as a proactive enterprise management style is proved, which ensures the formation and expansion of dynamic competitive advantages, taking into account internal and external changes in the operating environment by managing communications with potential market participants to create a competitive advantage, in particular personnel, partners and consumers. The key aspects of the structural transformation of railway transport based on the principles of marketing management are revealed. It is indicated that the formation of a marketing management system for railway transport should be carried out in several stages: the first stage is to analyze, evaluate and monitor the marketing environment; the second stage is to develop a marketing management system; the third stage is to ensure monitoring and adjustment of the marketing management system.Item Formation of the Anti-Crisis Concept of Increasing the Strategic Stability of Ukrzaliznytsia(Dnipropetrovsk State University of Internal Affairs, Dnipro, 2021) Martseniuk, Larysa V.; Dyomin, Yehor; Galushko, OlenaENG: The author revealed the essence of existing models of reform in railway transport. The Ukrzaliznytsia Anti-Crisis Change Management Program has been developed. New elements of corporate culture of Ukrzaliznytsia are singled out. Measures are offered for formation of favorable conditions for conducting economic activity of railways, creation of favorable information background of railway transport, activization of investment and innovation process. There are certain rules for financial risk management, namely: There are a number of certain rules that must be followed if the organization wants to strengthen the effectiveness of financial risk management: 1) Responsibility of senior management; 2) Existence of a common policy line and risk management infrastructure, different management chains, must be reliable and efficient; 3) Integration of risk management; 4) Responsibility of responsibility centers; 5) Assessment and ranking of the level of risk; 6) Independent expertise; 7) Contingency planning. The essence of the methods of Ukrzaliznytsia's corruption program is revealed. It is emphasized that an important element of any corporate culture are such concepts as: motivation, dedication of company employees.
