The article discusses methodological approaches to the construction of multicom-modity hierarchical communication networks and identifies the main tasks of pro-cessing and distribution of discrete correspondence flows, which allow to create favorable conditions for reducing material, financial and labor costs in transport systems with further mechanization and automation of production. The number of levels of hierarchy in the network, as a rule, is determined by the administrative division of the territory, the subordination of territorial administration bodies, the adopted technology for processing and distributing the flows of goods and information. Three levels of hierarchy are identified in the network — trunk, zonal and internal, and four types of nodes. Nodes of the first, second and third types, located on the trunks of the transport network or data transmission network and connecting them sections of vehicle routes or communication channels, constitute the trunk network. All trunk nodes have service areas that form zonal levels of the trunk network. Nodes of the fourth type are located in the internal service area of any main node and together with it form an internal network. Multicommodity communication networks are characterized by the presence of multiple sources and drains of correspondence flows (products or requirements). Correspondence is understood as a pair of different network nodes, between which there is a directed discrete flow of elements of a given value. In the backbone network, all correspondence is transmitted through communication channels or transported in vehicles in transport blocks of a given size (capacity, volume). The size of a transport block is measured by the number of units of correspondence that fit into it. All trunk nodes are sorting centers, in which correspondence is first sorted by destination addresses, and then packed into transport blocks. This article some aspects of the creation and implementation of spatial data infrastructure, information system and special mathematical support for transport networks and data transmission networks are presented. A conceptual approach to building an information-analytical decision support system for managing the processes of handling and distribution of discrete flows in hierarchical communication networks is considered. The issues of creating a toolkit and information platform (portal) for automating decision-making processes in the tasks of operational management, current planning and long-term development for trunk transport networks and data transmission backbone networks are discussed.
