CONSTRUCTION OF GIS FOR LOCAL OUTLET CHAIN
Special GIS for foodstuffs distribution network has been constructed, which includes three components: outlets coordinates, their semantic characteristics, and spatial customers’ “attraction polygons”. Semantic characteristics of outlets comprise quantitative description of trade attributes for rural minimarkets or local supermarkets. The boundaries of polygons (polylines of equal attraction) are based on physiological law of seller - customer attraction. In the offered model, the customer’s “physiological attraction” to the source of foodstuffs is compared with mutual attraction of oppositely charged bodies in physics. On the basis of the regression model of seller - customer “physiological attraction”, equal attraction polylines position is calculated (within walking distance, on time base). These polylines envelope attraction polygons of each rural shop “next door’. The offered technique makes it possible to represent a rural outlet chain as a GIS with coordinate- and attributive description. The model facilitates solving a social problem, i.e. determination of outlets optimal position for settlements households.
