Annotation. The article analyzes the interaction of the main railway and sea transport in modern conditions. A review of new studies and publications in this direction showed that their disadvantage is the lack of a systematic approach and focus on solving only certain organizational issues of interaction. The researches of scientists of the Dnipro University of Railway Transport named after academician V. Lazaryan, characterized by a comprehensive coverage of all problematic issues, are highlighted. Cases of servicing ports by non-public railway stations, in which additional costs of stevedoring companies arise in the absence of a mechanism for their compensation, are highlighted.To obtain an answer to the main research question - the nature of the shortage of receiving-departure and marshalling tracks at railway stations of port railway junctions and the associated delays of wagons waiting for delivery to the port for cargo operations, the work of the Odessa railway junction and the Odessa-Port station serving State Enterprise "Odessa Sea Trade Port".The paper analyzes the technical equipment of the railway infrastructure of the stations of the Odessa junction and formulates a conclusion about the sufficiency of the track development of spans, stations and the throughput of sorting devices. Based on the analysis of the plan for the formation of trains at the junction stations, the organization of work with dispatch routes and container trains, elements of a negative impact on the organization of the work of the port and the Odessa-Port station were identified. These include systemic violations of the train formation plan at the Odessa-Port station, as well as peak loads on the railway infrastructure of the station and cargo devices when servicing railway routes upon arrival and during the formation of dispatch routes and container trains. Inaccuracies in the unified technological process of operation of State Enterprise "OSTP" and the Odessa-Port station were noted when determining shunting locomotives serving the station and the port, which lead to an underestimated number of locomotives and, as a result, additional delays of the rolling stock.The main reason for the disruption of the normal operation of the infrastructure of the railway stations of the Odessa railway junction was established – a systematic violation of the current plan for the formation of trains.As a recommendation for the creation of an operator of the railway infrastructure of the Odessa-Port station and the access road of the State Enterprise "OSTP", the need to improve the draft law of Ukraine "About Railway Transport" was considered in order to create a legislative framework for companies of operators of railway infrastructure similar to European ones.

Purpose. The aim of the work is a comprehensive analysis of the technical and technological parameters of pre-port railway stations in Ukraine as key elements of the port infrastructure, ensuring the interaction of railway transport with seaports. Methodology. In the process of research, the methods of analysis and synthesis were used to study the content and the main provisions of scientific publications on the issues of establishing effective interaction between rail and sea transport,  with their subsequent comparison and generalization; methods of statistical analysis for research and systematization of technical equipment of port stations. Results. More than 60% of export cargoes go through Ukrainian ports; while 75% of export volumes are delivered to ports by rail. Currently, due to changes in the conditions for the functioning of the economy and the transport system of Ukraine, there is an imbalance between the capacities of ports and the port railway infrastructure for processing freight flows. Based on the analysis, it was found that the throughput of most stations does not correspond to the prospective, and for some stations - and the actual, volumes of work. In particular, for some stations, the capacity of track development is insufficient; a significant problem is also the low efficiency of the shunting means. An effective way to solve the problem of reducing the imbalance in the processing capacity of ports and the pre-port railway infrastructure is public-private partnership in the implementation of appropriate investment projects, the assessment of which should be carried out using modern scientific approaches. Scientific novelty. The authors have systematized the existing technical equipment of the port stations of Ukraine from the point of view of its sufficiency to ensure the existing and prospective volumes of transportation. Practical significance. The results obtained make it possible to provide a scientific basis for further research into assessing the throughput capacity of pre-port railway stations and the effectiveness of infrastructure projects aimed at increasing it.

Purpose. In modern conditions, the problem of increasing the efficiency of the railway transport of industrial enterprises is very urgent, and, first of all, this applies to enterprises of the metallurgical and mining industry, which are the largest recipients and consignors of goods by the railways of Ukraine. In this regard, the purpose of the study is to develop measures to increase the throughput and carrying capacity of the railway infrastructure of a mining enterprise in the context of an increase in the transportation of raw materials. Methods. The analysis of the technical equipment and technology of the railway transport of a large mining and processing plant in Ukraine was carried out using the methods of graphical analytical modeling. Results. The track development of the mining and processing plant ensures the delivery of iron ore from the quarry to the crushing and processing plant. The plant is presented as a system for transporting raw materials from loading points to unloading points, in which the process of its consumption is uniform (unloading ore on the tracks of a crushing plant), and the process of its replenishment is uneven (loading ore at loading points). Smoothing the uneven supply of raw materials between the points of loading and unloading provides the track capacity of the station adjacent to the crushing plant. The carrying capacity of the existing railway infrastructure of the plant does not ensure the mastery of the estimated volumes of transportation of raw materials. Analysis of the results of graphical modeling of the mining and processing plant showed that the limiting elements are the processing capacity of the crushing plant and long distances between the loading points and the abutment station. Organizational and technical solutions are proposed to increase the throughput of the railway infrastructure of the mining and processing plant. Practical significance. The results obtained can be used in the implementation of recommendations aimed at increasing the efficiency of the functioning of the railway transport of the mining and processing plant in conditions of an increase in the volume of transportation of raw materials.

Required Quality

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.

Within the last decade, research has focussed on corporate social responsibility (CSR) practices as a strategic tool that enables firms to improve stakeholder perception, brand image and corporate reputation. However, one area that remains understudied is the role played by CSR practices in managing corporate reputation under conditions of supply chain risk. To answer this research question, we conduct a literature review and develop the corresponding hypothesis. We test our hypothesis using quantitative analysis of both primary and secondary data collected from organizations dispersed globally. The results highlight that under conditions of supply chain network disruption risk, CSR practices play an important role in enabling firms to manage the negative impact of such risk drivers on corporate reputation. The study further suggests that CSR practices positively impact supply chain risk management (SCRM) practices and are a necessary condition for SCRM practices to be effective in improving corporate reputation of organizations.

Noise generated by railway wagons in operation is produced by large numbers of noise sources. Although the railway transport is considered to be environmental friendly, especially in production of CO2 emissions, noise is one of problems that should be solved to keep the railway transport competitive and sustainable in future. In the EU, there is a strong permanent legislation pressure on interior and exterior noise reduction in railway transport. In the last years in Slovakia, besides modernization of existing passenger wagons fleet as a cheaper option of transport quality improvement, quite a number of coaches have been newly manufactured, too. The new design is usually aimed at increased speed, higher travel comfort, in which reduction of noise levels is expected. However, not always the new designs meet all expectations. Noise generation and propagation is a complex system and should be treated such from the beginning. There are possibilities to simulate the structural natural frequencies to predict vibrations and sound generated by these vibrations. However, the real picture about sound fields can be obtained only by practical measurements. Simulations of the wagon’s natural frequencies and mode shapes and measurements in real operation using a digital acoustic camera Soundcam have been done, which showed that for the calculated speeds the largest share of noise from the chassis was not radiated through the floor of the wagon, as was expected, but through the ceiling of the wagon. To improve the acoustic properties of the wagon at higher speed, it was proposed to use high-volume textile insulation in the ceiling of the wagon. The paper briefly presents modern research approaches in the search for ways to reduce internal noise in selected wagons used in normal operation on the Slovak railways.

Ensuring the environment is safe for human life and health is one of the vital goals of the entire world community. Seaports inevitably affect the atmosphere, hydrosphere and soil. The main source of environmental pollution are merchant ships, which produce the most danger for the marine environment. The solution to the problem of waste management should be carried out through the state regulation, which should take into account the national characteristics of the population and the positive experience of European legislation. The author notes that the effective functioning and development of seaports depends on a number of factors, including the level of their technological and technical equipment, development of maritime infrastructure, compliance of the management system with modern international requirements, provision of regulatory framework. The current legislation of Ukraine and the requirements of the European legislation in the field of waste management are considered and analyzed. Approaches to solving the global problem in the context of European integration are proposed, namely: creating the necessary regulatory framework to reduce ship waste and cargo residues into the sea, as well as preventing or limiting the negative impact of seaports on the environment and human health; creation of modern infrastructure. The lack of regulation has a direct impact on the environment, on the efficiency of not only the port and transport industry, but also the economy as a whole. The study aims to highlight a fundamental criterion − waste management in the ports of Ukraine. It is concluded that in Ukraine there is no clear organizational structure of waste management. The author concludes that it is necessary to use European standards for waste management in ports

The railways are a priority transport mode for the European Union given their safety record and environmental sustainability. Therefore it is important to have quantitative models available which allow passenger demand for rail travel to be simulated for planning purposes and to evaluate different policies. The aim of this article is to specify and estimate trip distribution models between railway stations by considering the most influential demand variables. Two types of models were estimated: Poisson regression and gravity. The input data were the ticket sales on a regional line in Cantabria (Spain) which were provided by the Spanish railway infrastructure administrator (ADIF – RAM). The models have also considered the possible existence of spatial effects between train stations. The results show that the models have a good fit to the available data, especial the gravity models constrained by origins and destinations. Furthermore, the gravity models which considered the existence of spatial effects between stations had a significantly better fit than the Poisson models and the gravity models that did not consider this phenomenon. The proposed models have therefore been shown to be good support tools for decision making in the field of railway planning.DOI: http://dx.doi.org/10.4995/CIT2016.2016.4053

Dark Side

The academic research in the area of service marketing generally assumes friendly or neutral context of the encounters between employees and customers while providing or consuming the product. Recently, however, scholars are witnessing a new notion, namely ‘Dark Side of Marketing’ (DSM) which entails an increasing stream of pertinent publications in the literature. DSM is a complex yet multifaceted notion and refers to adverse effects of marketing paradigm implementation for humans, businesses and environment. Deviant behavior is a notable phenomenon pertinent to the nature of DSM, as it is mostly examined in relevant studies in comparison with other DSM manifestations. Deviant behavior is also emphasized in DSM studies because of its definitely negative impact on customer satisfaction, loyalty, WOM and, ultimately, on business performance metrics. To date, there is no DSM studies completed in the context of the Russian service industry as literature witnesses although this research question bears an apparent relevance for local business. This paper is destined to bridge this gap by defining the deviant behavior antecedents and gauging their consequences for marketing actors at the servicescape. The research results are based on empirical study of data collected from n=133 sample and on the analysis with utilization of Structural Equitation Modeling (SEM) method.
