Abstract

Traditional forms and ways of interaction between manufacturing and rail transport in the process of materials movement at the metallurgical enterprise with the changed production environment show its inefficiency. Moreover, the management of production and transport system focused on transportation where the transport only adapts to the needs of production does not meet modern requirements. Furthermore, this way of management leads to significant delays, costs and losses, which is unacceptable in a competitive market. At this stage, one of the most important question is creation of the effective management mechanism. This mechanism provides high efficiency of interaction between production and transport, shift of emphasis to the activation of production resources and elimination of production losses at all stages of the material movement processes. In order to solve this problem, it is necessary to make the transition between the management of rail transportation and logistics management process of material movement of enterprises. The logistics management process is based on a process view of working capital. Authors identified the technological scheme and indicators of interaction between production and transport. Moreover, they developed method to optimize the duration of process of cargo handling and resource costs and proposed the model of synchronization of cargo and transport modules. It was established that integrating role in the formation of a continuous process of material movement, linking in each flow all its participants. The flows between them perform logistic cycles: systemic and functional (technological). Consequently, the key indicators of logistics cycles are duration (productivity) of the structure and consumption of production and transport resources. Furthermore, authors propose the model to solve the optimization problem of the systemic cycle. It was indicated that end-to-end logistics management of the material movement process in the system cycle of handling the railcars of the external fleet should be based on technology of logistics system also called just in time. This technology is widely used in foreign countries and ensuring the delivery of raw materials semi-finished and finished products to the right place, in the right amount and exactly on time. In order to handle bulky cargoes, authors developed two types of logistics facilities: transport-cargo (TGK) for processing the external railcars park (VP) and transport and technology (TTK) to work with the railcars industrial park (ZP). The developed methodology was applied in the study to improve the efficiency of TGC for unloading of mass iron-containing raw materials (up to 800 railcars per day) at sinter plant of a large metallurgical industry. Furthermore, the developed methodology reduced the duration of acceptance and unloading of railcars of the external park from 20-22 to 10-12 hours. Moreover, the introduction of technical solutions is mainly implemented because of the resources of the sinter plant. The development and implementation of JIT logistics technology to manage the systemic cycles that form the process of material movement can significantly improve the efficiency of the organization of cargo handling processes and the operation of the transport infrastructure at the enterprise. Finally, it can reduce the volume of transport work and significantly reduce transport costs and production losses.
