Methodology of the organization of resource-saving production systems in railway transport

The paper presents the methodology of the organization of resource-saving production systems in railway transport. A description of the existing approaches to the organization of the energy management process in Russian Railways is given. The analysis of their compliance with the ISO 50001 is presented, the advantages and disadvantages of existing methods are analyzed. The basic principles of the proposed methodology are formulated and six stages of its implementation are presented, including the study of factors affecting the use of fuel and energy resources; the study of mathematical models of the use of fuel and energy resources; ensuring effective regulation and forecasting of fuel and energy resources consumption and tasks for saving fuel and energy resources; development of scientific and methodological principles for evaluating the effectiveness of energy-saving devices on railway transport; development of the scientific foundations of a strategy for the development a resource-saving production system in railway transport; development of improved methods and tools for monitoring the use of fuel and energy resources in production processes. The proposed solutions were tested at existing railway transport facilities, the results of which showed that the implementation of the methodology improves the efficiency of operation and the quality of organization of resource-saving production systems in railway transport. In particular, the use of machine learning methods allows to increase the accuracy of mathematical models of using fuel and energy resources up to 1.8 times, the resulting discrepancy between the results of predicting the consumption of fuel and energy resources and experimental data does not exceed 5 %, and the proposed patented technical and software solutions can be used to monitoring the fuel and energy consumption. On the basis of the obtained results, a number of regulatory documents of Russian Railways have been developed, which are implemented on the railway network and are used in organization of resource-saving production systems in railway transport.
