Economic and geographic method in modeling oil products cargo flows on the North-Caucasian railway region
In the process of modeling the freight market using the method of economic and geographical differentiation of the «areas of influence» of the loading stations, essentially higher-order classical algebraic curves arise (namely, Cartesian ovals and Pascal's snail). This circumstance means that the transport and logistic constructions produced in this way have a fairly fundamental mathematical basis. The methodology proposed by the authors for using the computational, analytical and graphical capabilities of mathematically oriented software products allows creating territorial models of the freight transportation process on the basis of a comprehensive assessment of the railway landfill infrastructure and analysis of the qualitative and quantitative indicators of freight companies' activities.
