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 Application of Local Exhaust Systems to Reduce Pollution Concentration Near the Road(Silesian University of Technology, Katowice, Poland, 2020) Biliaiev, Mykola M.; Pshinko, Oleksandr M.; Rusakova, Tetiana I.; Biliaieva, Viktoriia V.; Sładkowski, AleksanderEN: In this study, the methodological foundations of the technology for the local reduction of chemical pollution from vehicles were improved through the use of twolevel suction units and guide plates of various lengths installed on the nozzles of the suction devices.

For low-rise buildings frame technologies using lightweight thin-wall steel constructions have become significantly widespread. The main influence on a building’s spatial rigidity under lateral forces is taken by shearwalls. The necessary stiffness can be accomplished by setting definite constructional parameters that are selected according to the design approach. The purposes of the work are to receive the dependencies of the influence of the constructional features on the stiffness of the shearwalls (using FEM models) and to set the value of the stiffness of the shearwall of any configuration by linking its parameters with the corresponding parameters of a standard shearwall through the established dependencies. The received dependencies of the effect of the main constructional factors and design approach for the stiffness of shearwalls can be used to provide spatial rigidity. A simplified design approach for estimating the influence of the main constructional features of shearwalls on their rigidity has been developed.Item Directions of Anti-Crisis Management of Restaurant Business(ДДУВС, Дніпро, 2021) Pshinko, Oleksandr M.; Charkina, Tetiana Yu.; Pikulina, Olena V.; Basistha, NandiniENG: 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.

Currently, the most common is the vibration method of molding concrete and reinforced concrete products. However, the issues of choosing a rational mode for compacting concrete mixtures, its effect on density and, accordingly, strength, water resistance, frost resistance and deformation properties of concrete, remain insufficiently studied. The best results are obtained by using the optimal frequentative vibratory influence method. In this case, concrete strength is increased by 25-30 % in comparison to the factor of concrete compacted by traditional method.Item Hubs as a Key Tool for Improving the Quality of the Service and Development of Multimodal Passenger Traffic(The Silesian University of Technology, Faculty of Transport, Katowice, Poland, 2022) Pshinko, Oleksandr M.; Charkina, Tetiana Yu.; Martseniuk, Larysa V.; Orlovska, Olexandra V.ENG: This article stresses the need to develop multimodal passenger transport. Particular attention is paid to the construction of HUBs based on railway stations. HUB is the transport interchange node, passenger complex, which redistributes passenger flows between transport modes and directions. They allow to optimize transportation processes, as well as to create an infrastructure for convenient and fast passenger transfer between different transport modes. The preconditions for creating organizational conditions to ensure the sustainable development of the passenger railway transport sector are outlined. In the near future, combined passenger transport with the participation of several modes of transport will attract tourists from around the world. The authors’ concept of the term “passenger comfort zone” is proposed, which takes into account all the needs of modern tourists. The mechanism of multimodal transportations of passengers by railway transport in interaction with other participants of the servicing process is presented. A model of institutional support for the development of multimodal passenger railway transport is proposed to create conditions for integrated transport services for passengers by the passenger railway transport complex. The expediency of forming a system of railway passenger HUBs in Ukraine is vital to attracting investments to improve transport and tourism infrastructure, as well as to roll stock and a range of services for the benefit of all stakeholders in the transport sector (e.g., the state, investors, and passengers).Item Hydraulic Concrete Composition and Properties Control System(Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпропетровськ, 2015) Pshinko, Oleksandr M.; Krasnyuk, Andrey V.; Hromova, Olena V.EN: Purpose. Scientific work aims at the development and testing of information system to meet the challenges of concrete composition design and control (for railway structures and buildings) based on the physico-analytical method algorithm for hydraulic concrete composition calculation. Methodology. The proposed algorithm of hydraulic concrete composition calculation is based on the physicochemical mechanics and in particular on the rheology of elastic–viscous–plastic bodies. The system of canonical equations consists of the equations for concrete strength, absolute volume, concrete mix consistency as well as the equation for optimal concrete saturation with aggregates while minimizing cement content. The joint solution of these four equations related to composition allows determining for the materials the concrete composition of required strength, concrete workability with minimum cement content. The procedure for calculation of hydraulic concrete composition according to the physico-analytical method consists of two parts: 1) physical, which is laboratory testing of concrete mix components in different concrete compositions; 2) analytical, which represents the calculation algorithm for concrete compositions equivalent in concrete strength and workability that comply with the specific conditions of concrete of designing the concrete composition with the desired properties for railway structures and buildings it was proposed to use the information technology in the form of a developed computer program whose algorithm includes the physico-analytical method for hydraulic concrete composition determination. Originality. The developed concrete composition design method takes into account the basic properties of raw materials, concrete mix and concrete, which are predetermined. The distinctive feature of physico-analytical method is obtaining of a set of equivalent compositions with a certain concrete mix consistency and required concrete strength, which allows to optimize the concrete composition by any optimality criterion, depending on the operation conditions. Practical value. Using the developed method will expand its functionality when applied in the form of the composition calculation computer program for the construction and repair of surface and underwater structures. The use of physico-analytical methodat production site will simultaneously solve the economic problems of construction and maintenance cost reduction,component saving and ensure obtaining the concrete with the set properties for specific operation conditions of transport engineering structures.Item Improvement of Concrete and Building Mortar Technology Using Secondary Mineral Resources(Національний гірничий університет, Дніпро, 2022) Pshinko, Oleksandr M.; Pavlenko, T. M.; Dekhta, Tatyana M.; Hromova, Olena V.; Steinbrech, Oksana V.ENG: Purpose. Improving the technology of concretes on the basis of secondary mineral resources (waste foundry sand of metallurgical and machine-building industry, ash-and-slag mixes of thermal power plants). Methodology. Generally accepted standard methods in the study of the basic properties of raw materials, concrete mixes and concretes are used in the work. The samples were moulded using specially made laboratory vacuum equipment. Findings. The study results on the main properties of concretes on the basis of secondary mineral resources confi rmed the effectiveness of vibrovacuum technology. For example, the strength of ash-and-slag vacuum concrete is on average higher than the strength of vibrocompacted concrete from a mobile concrete mix by 6–10 MPa or by 60–100 % (depending on the cement consumption). Also, high-quality concretes with moderate cement consumption for various types of construction are obtained on the basis of waste foundry sand. Originality. Scientifi c and technical bases of the technology of vibrovacuum concrete on the basis of waste foundry sand and ash-and-slag mixes were developed. Practical value. Through the development of the technology of vibrovacuum products based on secondary mineral resources concrete, high-quality concretes (increased strength, frost resistance, etc.) were obtained for road and other types of construction. This technology allows applying the existing technological equipment without fundamental design changes, carrying out immediate dismantling of moulded products, which signifi cantly reduces the metal consumption of the technology.Item Improving the Efficiency of the Heating System for Public Buildings Infrastructure in the Context of DNURT(Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпропетровськ, 2016) Pshinko, Oleksandr M.; Kuznetsov, Valeriy; Yatsenko, Dmytro K.; Gabrіnets, Volodymyr O.EN: Purpose. The paper analyses the possibility and terms of increasing the efficiency of heating and ventilation systems of public buildings at the present stage of development and the specific climatic conditions of Ukraine. The main purpose is to develop specific measures for public buildings, which will lead to a significant reduction in energy costs for heating and air conditioning system. The example is similar system of DNURT compact campus, which is heated with its own autonomous boiler that uses natural gas. Methodology.

These losses are compared with those in the world practice and based on the comparison and analysis of the current system there are offered the ways to reduce the heat loss values through the use of various technical and organizational methods. The paper also proposes involvement for this purpose of secondary and alternative energy sources. The secondary energy resources include the heat that is emitted by people and that coming out with the air during ventilation of buildings. The renewable sources include solar and geothermal energy. To enhance the heat transfer medium temperature capacity it is proposed to use the heat pumps. Findings. The maximum possible use of the proposed measures and implementation of rational schematic and engineering solutions for heat and hot water supply systems cam reduce the energy loss for heating and hot water by 30-35%. Originality. The paper for the first time proposed the use of new integrated approaches to maintain the desired heat balance in the winter period, as well as the new schematic solutions for heating and ventilation systems, both in winter and in summer, based on the use of heat pumps and secondary energy resources. Practical value. The introduction of the proposed schematic solutions and approaches demand relatively small capital investments and do not require significant reconstruction of already installed systems.Item Influence of Constructional Features on Shear Walls’ Stiffness in a Lightweight Steel Framing Buildings(Nauka i studia, Przemysl, 2013) Savytsky, Mycola V.; Zinkevych, O.
