The aim of this paper is to present results of modeling of regional infrastructures. The paper is based on research into customer relationship management in SMEs. Part of this research was the identification of the influence of foreigners with long-term residence in the Czechia on supplier-customer relationships given by the region of origin of foreigners. The research was focused on regional geospatial relations, associated with dislocation of source countries of which 185 have been identified. The aim of the analysis was to identify spatial relationships (clusters of areas with increasing, decreasing and constant distribution of the number of foreigners) using a virtual infrastructure modeled using minimal distances. To identify relationships, a model has been developed to model infrastructure at different regional levels. Infrastructure properties were set using additional parameters. However, this modeled infrastructure shows disproportions which need to be identified and eliminated, and in this sense, the generation of infrastructure. Comparison method, exploratory analysis, multiagent systems simulation, incidence and precedence matrix and geostatistics were used to identify infrastructure characteristics. The research proved the importance of individual infrastructure parameters, especially the number of minimum edges for individual states.
