CONCEPTUAL MODEL OF RAILWAY CAR TRAFFIC ORGANISATION BASED ON THE END-TO-END CONTROL OF FREIGHT DELIVERY TIMES
Introduction. The article presents the analysis of non-compliance of delivery times of railway cargoes with the regulatory time frames. The analysis reveals a decrease in the reliability of delivery, one of the most important quality indicators. The authors assess the operation of existing automated control systems, which shows discontinuities and non-automated functions in the framework of the end-to-end control of the goods and empty cars delivery times. The purpose of the article is to propose and justify the use of a conceptual model for organising car traffic, based on end-to-end control of delivery times and risk-oriented impact on the limiting technological elements. Materials and methods. The authors applied the methods of the modern theory of traffic management, the theory of mathematical statistics and the theory of decision making. Results. The authors propose a conceptual model based on end-to-end control of goods delivery times and a risk-oriented impact on the limiting technological elements as a part of development of end-to-end process of the goods and empty cars delivery. The model highlights the following key provisions: control of the actual delivery time to stations by assessing the compliance with the technological standard operation times; end-to-end risk-oriented control of actual delivery times of cargo and empty cars along the entire route; providing recommendations to accelerate the advancement of the car traffic based on the technical and economic feasibility study. Discussion and conclusion. The implementation of the proposed conceptual model enables to employ scientifically based operational decision-making to control the flow of the traffic at each stage along the route and to improve the quality of transport services and the quality of operational work of railway transport. The conceptual model can be implemented as a separate module integrated into the existing automated station control system.
