Item Especially the Functioning of Railway Stations in the Conditions of the Organization of Transport Dangerous Goods(Дніпропетровський національний університет залізничного транспорту ім. академіка В. Лазаряна, Дніпропетровськ, 2016) Kozachenko, Dmytro M.; Zhuravel, Irenа L.; Zhuravel, Vyacheslav V.ENG: Purpose. Ensuring a sufficient level of transport safety is an important task in the context of development of railway transport as a part of international transport corridors and under increasing freight traffic volumes. The intensification of the transport process when there is the significant depreciation of fixed assets actualizes the development and implementation of methods to of improving the safety of railway transportation of dangerous goods, as well as technological and organizational measures, which are directed decrease of risks of emergency situations with its goods. Methodology. The methods of system analysis and theory of the railways operating management were used. Findings. The regulatory framework of the dangerous goods transportation by rail was characterized. The main indicators of the dangerous goods transportation under modern conditions of railway transport functioning were investigated. A detailed structure of the factors, which influence on the stations operating conditions during the transportation of dangerous goods was developed, and the measures of the stations technology improving in order to increase the traffic safety were proposed. Originality. Authors had detailed features of the functioning of the railway stations functioning under the dangerous goods transportation management. Practical value. Taking into account the factors and implementation of the proposed measures will improve the safety level of dangerous goods processing at railway stations.Item Researching Operation of the Railway Stations with Using of Their Ergatic Simulation Models(Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпропетровськ, 2013) Bobrovskyi, Volodymyr I.; Kozachenko, Dmytro M.; Vernigora, Roman V.ENG: The general scheme of railway station’s model and technique of formalizing the technologic processes at stations are described. Designed model can be used for optimization of technical and technological parameters of railway stations, including with using the grapho-analitical method.Item Techno-Economic Evaluation of the Efficiency of Improvement of Techniques Rationing Fixing Rolling Stock on the Station Tracks(Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпропетровськ, 2013) Kozachenko, Dmytro M.; Pasichnyi, Oleksandr M.ENG: Purpose. This is dedicated to evaluation of the efficiency of improvement of the advanced method of normalization of quantity of wheel chocks for fixing rolling stock on station tracks, which was proposed as a result of former study. Methodology. In this study the simulation modeling of station work is used for calculation of rolling stock downtime. The method of techno-economic comparison is used to evaluate the efficiency of improvement of the new method of rationing number of wheel chocks for fixing rolling stock. Findings. The effect of the proposed method to the conditions of work of the railway stations had been analyzed. It was revealed that the introduction of improved methods of rationing fixing rolling stock will lead to substantial savings in operating costs of the railway.Originality. The advanced method of normalization of quantity of wheel chocks for fixing rolling stock on station tracks is proposed at first, that’s why the techno-economic evaluation of its efficiency has also been made for the first time. Practical value. The result of this study shows that use of the advanced method of evaluation of wheel chocks number for fixing rolling stock will lead to savings in railway’s operating costs because of decreasing rolling stock downtime.
