GRAPH MODELING OF THE EVOLUTION OF STRUCTURES OF TERRITORIAL-PRODUCTION COMPLEXES IN NEW PIONEERING AREAS

A graph model technique is used to analyze the pattern of urban places in the Bratsk–Ust'-Ilimsk complex on the middle Angara River in Siberia. The places, serving as vertices, are connected into tree-like structures on the basis of a data matrix that uses the founding dates of the places and the distances between them. The resulting pattern of location reveals a linear-nodal structure that is typical of areas in early stages of economic development, such as the Middle Angara district, with its large hydroelectric stations and energy-intensive industries like aluminum and woodpulp. The graph technique is suitable for analyzing patterns of location at various stages of development and to predict the future evolution of the structure of urban places.
