RnD Article calculation

The results” of the article considers the formulation of problems and graphical interpretation of the results of numerical calculations for the case of a two-dimensional region of change of the two-dimensional variable of this problem (in economic problems of transportation, one component of the variable can characterize the location of an object in the network, the second - some economic properties, for example, transportation costs object to that location from the starting point). The cases of backbone networks are considered. The situation is a model one; by analogy, we can consider a backbone network of any length and any number of subareas.
