ЛОГІСТИЧНИЙ ПІДХІД К ОРГАНІЗАЦІЇ НЕЗБАЛАНСОВАНИХ ВАНТАЖНИХ ПЕРЕВЕЗЕНЬ НА ТРАНСПОРТНИХ МЕРЕЖАХ

Abstract

This article describes the logistics approach, which through the use of transport technologies solves the problem of optimal organization of unbalanced transportation of goods on transport networks. This situation often arises when the volume of deliveries of goods from its suppliers exceeds the capacity of warehouses of its consumers. In this case, we are faced with the need to use intermediate points for the temporary storage of surplus cargo and as a consequence of a multi-stage transport task. The object of research is the process of freight management on transport networks. The purpose of the work is to study the peculiarities of decision-making on freight transport management on transport networks with the use of information technology. Research methods - the method of reducing the network representation of freight into a matrix model and the method of potentials to find the optimal plan of freight. The matrix of transport correspondence between suppliers, consumers and intermediate points is not set explicitly, but simply introduced a map of their location, ie the transport task is set using the transport network. With the help of the modified Dijkstra method, the shortest routes between suppliers and consumers of cargo are found on the transport network, as well as between them and intermediate points for temporary storage of excess cargo. The optimal plan of cargo transportation is calculated with the help of the designed software and tool complex, which combines the stage of reduction of the network representation of the scheme of cargo delivery to the tabular form and the stage of planning and further implementation of mass cargo transportation on the transport network.
