Transportavimo išlaidų modeliavimas ir optimizavimas

The article deals with ways of flow distribution in the transport network in order to minimize transportation costs. It describes the structure of transportation costs and principles of defining the dependence on the volumes of flow in pertinent transport modes, such as railways and road transport. It analyses classical models of flow distribution and presents a new approach to flow distribution in a transport network, based on flow optimization in individual contours or groups of contours of the network. The suggested approach is more rigorous than classical ones in mathematical terms and therefore avoids problems of heuristic nature that characterize classical approaches. The suggested approach has been tested in experimental calculations
