DESIGNING A MULTIMODAL TRANSPORT NETWORK

Objective: To create a methodology for designing a multimodal transport network under various scenarios of socioeconomic development of the Russian Federation and its regions which take into account the influence of factors that create initial-information indeterminacy in decisionmaking. Methods: System theory, partitioning principle, theory of sets, theory of probability and mathematical statistics, basics of information theory, graph theory and reliability theory; as well as methods of system analysis, mathematic simulation of processes and systems, mathematical logic, decision-making, dynamical programming, multi-objective optimization, economic evaluation of efficiency of design solutions were applied. Results: The authors developed and proposed a concept for designing methodology of multimodal transport networks, systemic presentation of multimodal transport networks, four-level partitioning and set-theoretical presentation of multimodal transport networks layout, mathematical simulation of multimodal transport network development strategy which takes into account the scenario of socioeconomic development of a region under study, balanced system of indices for evaluation of multimodal transport network development strategy and managing the trajectory of change of its layout and capacity in accordance with set strategic objectives, method for forming layout of multimodal transport network, method for forming a variety of possible strategies of gradual changing of layout and capacity of multimodal transport network objects, method for forming an area of efficient multimodal transport network development strategies, technology for decision-makers’ work with efficient strategy area for decision-making. Practical relevance: This methodology can be used in investment evaluation and technical and economic feasibility study of strategies of multimodal transport networks’ layout and capacity change strategies as an aggregate of multimodal transport corridors designed with the purpose of implementation of strategic tasks of development of a country’s single transport network.
