Turpak S. Theory development of railway transport functioning at metallurgical enterprises

The object of research is transport-technological processes of micro logistical systems (MLS) of rail transport metallurgical enterprises (RTME). The subject of researches is logistics technology of the intelligent control of RTME MLS. The purpose of the research is the increase of efficiency of functioning of the RTME by reducing logistics costs, solution of the scientific problems of creation of the logistics system, planning techniques and operational management of the transportation, which, in contrast to the existing approach of separate solutions to specific problems, will allow you to perform a comprehensive optimization of transportation systems. Research methods: the formalization of control systems of transport and technological processes is based on the principles of the system analysis and logistic approach; factor and regression analysis of transport streams parameters are used to select and determine the impact of major factors on the performance of transport; the probabilistically-statistical analysis of the intervals of the train movement was executed to determine the parameters of the input flows of MLS; scientific provisions of the theory of automatic control systems were used to define the structure of the simulation model of the delivery system and cargo handling on RTME; when choosing optimal parameters of the functioning of the transport system of metallurgical enterprises the method of simulation modeling was applied; the methods of the statistical analysis of dynamics of the time series were used to prognosticate cargo traffic. Scientific approaches to the formation of intelligent logistics technology of the operational management of the transportation that optimizes generalized logistics criterion for the allocation of resources of the transport system through the implementation of new technological procedures for the selection of RTME operating parameters were theoretically proved. Obtained results allow to improve the efficiency of RTME and reduce transportation costs due to the implementation of logistics technology of the smart control systems usage and to determine the optimal parameters of functioning of the transport system. The work was implemented at PJSC "Zaporizhstal", PJSC "Zaporozhye Ferroalloy Plant", PJSC "Dneprospetsstal", PJSC "Zaporozhogneupor", JSC "Central transport company", JSC "Meta-Trans". The scope is the railway transport of metallurgical enterprises.
