118-130The 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. -

146-158Subject of research - the evolution of logistics objects (LO). The purpose of the research is the development of methods to study the LO in their development, taking into account changes that they execute logistics functions. Research methodology based on set theory, graph theory, theory of transport systems, general systems theory and the author's methodology terminalistics. The authors studied the most significant for the evolution of the LO characteristics and factors influencing them. The condition of LO is a set of indicators identifying the overall hierarchical system (defining its type) and characterizes his work in general. This study describes an evolutionary-functional approach. This approach is reflecting the characteristics of the development of the functional arsenal of LO and its role in the system of delivery. Its essence is also presented graphically. The author has developed a classification of types of LO, given their evolution and hierarchy. The basis of the typology of LO is the LO evolution of the implemented logistic services. Also this study describes the stages of functional development of the LO. A parametric description of the LO and the conceptual framework taking into account the classification and evolution of the LO present in this study. Еhe author proposes the methodology of research LO on the basis of the evolution of the network states. The evolutionary-functional theory is reflected in the form of a "rhombus evolutionary and functional development of the LO." This theoretical and graphical model evolutionary network conditions may be applicable: 1) in determining the terms of the best mode of operation LO for planning of objects of terminal and warehouse infrastructure, 2) the operation and development of terminal and warehouse infrastructure; 3) as an evaluation tool to identify bottlenecks and system improvement of all aspects of the work LO. The results of the study can be used in the design, planning, development and evaluation of objects of terminal and warehouse infrastructure of Russian Railways.
