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.

This will allow to optimize the maintenance costs of such facilities and increase the economic efficiency of transport construction enterprises. The results of the study are as follows: the results of the study on determining the main factors affecting the volume and structure of works of transport construction enterprises are presented. The originality and practical value of the research lies in the fact that the article systematizes existing areas of negative impact of rolling stock on infrastructure objects, which directly affects the volume and structure of works of transport construction enterprises, which allows rational management of the economic efficiency of their activities. The conclusions of the study are as follows: the results of the study on the analysis of the impact of rolling stock on infrastructure objects proposed in the work will allow to improve, in the end, the management of the economic efficiency of the activities of transport construction enterprises. The results of the conducted research can be useful for the enterprises of JSC "Ukrzaliznytsia", which, due to their functional purpose, have to perform works on the elimination of wear and tear of infrastructure facilities in order to improve the operational activities of railway transport.
Anti-Crisis Management of Passenger Transport as a Factor of Increasing Railway Competitiveness
(Національний технічний університет «Дніпровська політехніка», Дніпро, 2020) Pshinko, Oleksandr M.; Orlovskaya, Oleksandra V.; Charkina, Tetiana Yu.; Carra, A. 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.

ENG: The purpose of the article is to study the specifics and develop measures of anti-crisis marketing of railway engineering enterprises. The relevance of anti-crisis marketing of railway engineering enterprises lies in the need to effectively respond to changes in the economic environment, competitive pressure and changes in demand for products that arise during crisis situations. The role of anti-crisis marketing in the anti-crisis management of enterprises is to ensure effective interaction with other functional units, operational analysis of the market situation and making strategic decisions to overcome crisis phenomena. The main functions of anti-crisis marketing are the analysis of market trends, forecasting changes in demand, development of strategies for maintaining and developing market position. The main tasks of anti-crisis marketing are to ensure the stability of sales, maintain customer loyalty, optimize marketing costs and increase the competitiveness of the enterprise. To achieve the goals of anti-crisis marketing of railway engineering enterprises, it is proposed to use such methods as: diversification of products and sales markets; flexible pricing; market and competitor monitoring using benchmarking; active use of digital marketing; implementation of СRM (customer relations management).
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.
The Concept of Anthropotechnics in the Social and Humanitarian Dimension
(Український державний університет науки і технологій, Дніпро, 2024) Bazhan, Serhii P. ; Chernova, Nataliia S.
ENG: Purpose. This research defines the conceptual foundations of anthropotechnics as a science that studies modern processes of interaction between humans and technologies in the socio-humanitarian dimension. Theoretical basis. The authors use the method of anthropological analysis, which allows generalizing the approaches of anthropotech-nics in the socio-cultural context in the "human-technology" system. Originality. Based on the results of the re-search, the understanding of the essence of anthropotechnics as a science that studies human interaction with tech-nologies and technical systems has been clarified. The idea of implementing anthropotechnical approaches to the management of the educational process gained further development, in particular in the context of practical training of applicants for education, distance learning, and dual education forms. The concept of professional activity and professional self-realization of the individual is taken into account, and promising directions in the development of anthropotechnics in the context of the application of artificial intelligence are determined. Conclusions. Considering anthropotechnics in a philosophical and sociocultural dimension is an important approach to understanding the in-teraction of technologies, people, and society as a whole, where technologies affect human perception of the world and interaction with it. The range of approaches chosen by the authors, the disclosure of their principles and catego-ries allows for considering the object of this research – anthropotechnics as a modern science – in a multifaceted and holistic way, to interpret the results of the research based on the use of the basic categories of approaches: a person, equipment, technology, activity, development, personality, system.
Congruent Approach to Marketing Management of Railway Transport Development
(Український державний університет залізничного транспорту, Харків, 2024) Задоя, Вячеслав Олександрович
ENG: The article proves that digitalization is now a key mega-trend that determines the development of enterprises, industries and national economies of the world. Digital transformations continue, which radically changes not only the external and internal business processes of railway transport, but also the consciousness and preferences of consumers of transport and logistics services, complicates the operating conditions of JSC "Ukrzaliznytsia" and requires rapid adaptation to the transformed environment. It will prove that in these conditions, marketing management should be considered a key element in the process of ensuring the development of railway transport. In order to overcome the current problems of railway transport, changes in each element of the Marketing Management System (general economic, marketing, managerial) were studied. We will especially focus on the latest trends in marketing communications that have emerged under the influence of environmental transformations. Based on the research of recent publications on this topic, we identified areas that will be relevant in the coming years in Ukraine and in the world. They are: data-based communication management (big date); continuous segmentation of consumers and the market; omni-channel; event virtualization; marketing technologies (Martech); request for business trust; streaming shopping; social responsibility; experimental marketing; maximum consistency of actions of marketing and sales teams. It is established that under the influence of digitalization, a personified transformation of individual elements of marketing management of railway transport is currently taking place, which created the basis for solving local problems, but this did not allow for positive changes in the entire railway transport economy. Haphazard, isolated, and sometimes contradictory management actions within the components of marketing management have created a significant obstacle to the formation of competitive railway transport that is not able to provide positive changes in the national economy. It is proved that the congruent approach can be the basis for overcoming these negative trends. It will allow us to form a fundamentally new conceptual field for the formation and implementation of the sectoral policy for the development of railway transport in Ukraine. Conceptual provisions for applying a congruent approach to marketing management of railway transport development are proposed.

Directions of Anti-Crisis Management of Restaurant Business
(ДДУВС, Дніпро, 2021) Pshinko, Oleksandr M.; Charkina, Tetiana Yu.; Pikulina, Olena V.; Basistha, Nandini
ENG: In this article, the authors emphasize that the pandemic and quarantine measures have brought the normal functioning of the world economy and the activities of many enterprises. 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.

Personalized Development Plans: Data and analytics enable HR professionals to create personalized development plans for employees based on their strengths, weaknesses and career aspirations. This personalized approach can increase employee engagement and retention. Optimizing recruitment processes and talent retention with the help of data analytics opens up new opportunities for increasing the competitiveness of organizations.
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. Methodology. The author offers the directions of tourist flows control, which differ from the current expansion of services to tourists in Ukraine. The development of extreme tourism with the help of co-operation of railways and sport federations was proposed. Findings. During the research the author proved that the implementation of the tasks will be promote: 1) increase in budget revenues at all levels of the inner extreme tourism; 2) raise the image of Ukraine and Ukrainian Railways; 3) increase the share of tourism and resorts in the gross domestic product to the level of developed countries; 4) bringing the number of employees in tourism and resorts to the level of developed countries; 5) the creation of an effective system of monitoring the quality of tourist services; 6) the creation of an attractive investment climate for attracting the investment in the broad development of tourism, engineering and transport and municipal infrastructure; 7) improvement the safety of tourists, ensure the effective protection of their rights and legitimate interests and preservation of the property. Originality. The author shows the theoretical generalization and new solution of a scientific problem.

Directions of Integration of Railway Transport of Ukraine into the European Railway Network
(Дніпропетровський державний університет внутрішніх справ, м. Дніпро, 2022) Martseniuk, Larysa V.; Kovalenko-Marchenkova, Yevheniia; Furfaro, Ricardo Daniel
ENG: 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”.
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, Olena
ENG: 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.
