The dissertation is devoted to increase the efficiency of cargoes delivery in international piggyback connection. As a result of problems analysis in the international transport implementation in Ukraine, was established that the main problems of international road transport can be attributed to: imperfect customs legislation of Ukraine; accident rate; high costs; unsatisfactory condition of the road complex (51,1% does not meet the requirements for equality, 39,2% - for the strength.); technical condition of cars; low qualification and driver's responsibility; incompetence of forwarding groups; untimely payments with carriers; non-compliance with the terms of loading / unloading of vehicles during loading of products; big queues at the border. With the help of mathematical modeling, it is possible to estimate functional links between different parameters that influence the delivery time in international communication. In order to establish the equivalent cargo delivery distance, the hypothesis was taken into consideration: placement parameters of all participants in the transport process would increase the efficiency of international cargo delivery. With the help of the developed mathematical model of determining the equivalent distance on the cost criterion, when the consignor coincides with the railway station and model, when the shipper is remote from the terminal, the factors that influence the determination of the area of effective use of the piggyback connection are established. With the help of mathematical modeling methods, the effective zone of piggyback connection use in the international delivery of goods by the cost criterion is determined. Graphically, the area of effective use of the piggyback connection looks like a deployed parabola, the top of which is on the line of the rail route. The established area of efficient use of the piggyback allows choosing a rational delivery scheme based only on the tariffs for the transportation and disposition of the consignee. Based on the conducted research, economical-mathematic model for analyzing the equivalent distance based on the cost criterion, taking into account the disposition of the consignor and consignee, the distance between the railway stations of departure and destination, the railway tariff for transportation and the cost of road transportation, was developed. The area of effective use of the piggyback connection based on the model of determination of the equivalent distance according to the criterion of the cost of transportation is specified. Unlike previous studies, it has been established that the area of effective use of the piggyback connection is not sustainable, and is determined for each individual case of dislocation of the consignor with unchanged other parameters. The ease of use of the developed economical-mathematic model has advantages over all previously proposed because it allows you to calculate the economic feasibility of using the type of combination not only as an area of effective use, but also for each individual case to determine the efficiency of choosing the type of connection. The use of models gives the opportunity justify economically the choice of type connection and will allow the motor transport company to reduce transportation costs by 10-15%.
