The subject of the study - is a terminal network. The purpose of this study is to develop a set-theoretic model of terminal network. Research methodology bases on set theory, theory of transport systems, General systems theory and the author's methodology of terminalistics. In this study describes of the terminal network, its key elements and its logistics facilities; the factors affecting the composition and configuration of the terminal network. Also this study develops the model of the terminal network as a logistics chain, and its proposed integrated set-theoretic model of the terminal network of the region. A graphic model of the terminal network as a supply chain presents in the study. The task of finding the best option terminal network in this formulation becomes a three-tier and two-stage. The results of the study can be used as mathematical tools in the design, planning, development and evaluation of objects of terminal and warehouse infrastructure of Russian Railways.

Currently, much attention is paid to the creation of terminal «dry port» for maintenance of traffic node. «Dry port» is one of the possible ways to increase capacity of the transport node. The capacity of transport node depends on the following interrelated elements: infrastructure solutions, technological, technical, organizational, and exogenous. Insufficiency of technical equipment, low level of production culture, informational inconsistency - lead to excessive downtime of vehicles at berths and terminal and warehouse facilities of the port. Technical devices, shunting locomotives, lifting and transport equipment cannot cope with the increasing flow of transportation of containers and cargo, leading to paralysis of the movement of freight flows. The result is the accumulation of cars at the entrances to the transportation hub the formation of «abandoned» trains. The lack of logistics management principles of traffic promotion in the organization of multimodal transport required a modern approach to organization of effective work of the transport node. In this work the effective interaction between various types of transport in the transport node is represented in the form of a set-theoretic model. Considered the elements that contribute to the throughput of dry ports and sea port. The efficiency of technological processes systems of interaction of railway and marine transport in the node depends on the following conditions: the actual time of wagons in transportation must comply with regulatory process time; organization supply wagons in accordance with the processing capabilities of the cargo platforms; ensuring the maximum amount of overload of goods on the «direct option». To implement these conditions it is necessary to organize the interaction of different modes of transport in the transport node together with the terminal «dry port» in the system «terminal - station - port», in which the capacity of the railway component of the transport node is treated comprehensively along with the «dry port». Further technical and technological development of transport nodes is organization of cargo handling outside the port terminal «dry port».
