“…Depending on the qualitative estimation of the set of these parameters, an auxiliary database is created for the categories of delivery: the use for each type of cargo, only for logistics operations with the objective delivery function subject to time, only for logistics operations with the objective delivery function subject to cost (for example, for formation of warehouse reserves, in particular, coal for heat-power stations) [9,19,[23][24][25][26]. Formation of such an auxiliary database by categories of delivery allows to save time of calculations and resources of computer equipment [27][28][29][30].…”

“…In addition, the practical operation of various software systems aimed at finding the optimal route for the transportation of goods by different modes of transport, in the presence of transit points for their transshipment, in the case of large databases, shows that there is still a need to create a mathematical model that would allow them to carry out efficiently and with minimal load of computer resources to perform such calculations [9,10,11,12].…”

One of the problems of modernizing multimodal transportation of goods in post-Soviet countries is the optimization of the transport supply chain. This requires, in particular, a software package that is to be adapted to local conditions, to the expanded set of risks and the need, in general, to perform optimization on the base of fuzzy data. When choosing the objective function, it is necessary to take into account not only the cost of the specific option of route, the time of transportation, but also the degree of reliability of both the contractors and the infrastructure. For creating a mathematical model were used graph theory and fuzzy logic. Separate types of transport are considered as directed graphs. The set of directed graphs of modes of transport is a multidimensional graph, under the presence of connecting arcs between their nodes. These nodes represent the points of transshipment. The software package assesses the reliability of each section of the supply chain. The developed software package using the proposed mathematical model will allow improving multimodal transportation of goods.
