ENG: The object of this study is the process of rendering transport and forwarding services when organizing multimodal cargo transportation in international traffic. The task to tackle was predetermined by the need to devise recommendations for choosing the optimal cargo transportation route, taking into account the individual requirements of the customer and performance indicators of the forwarders at the transport and forwarding company. A simulation model of the work of a transport and forwarding company in the organization of multimodal transportation of goods was built and implemented in the GPSS World simulation automation software. The model involves the optimization of the duration of service provision and makes it possible to determine the required number of transportation department specialists to enable effective cooperation with customers. When constructing the model, the duration of business processes in the organization of multimodal transportation was taken into account. In addition, the model accounts for the probability of errors and service delays, as well as the average delay time when errors occur, which will make it possible to take into account the additional work time of the forwarder to eliminate them. The application of the built model in practice will allow specialists at transport and forwarding companies to organize multimodal transportation according to several alternative routes that meet the individual needs of the customer. It will also make it possible to determine the optimal number of forwarders needed to work at the multimodal transportation department. In this case, the duration of rendering transport and forwarding services will be reduced by 12–16 %, the waiting time in queues for service will decrease by 9–13 %, and the efficiency of the work of specialists at the multimodal transportation department will increase by 9–14 %.

ENG: This study’s object is the process that organizes and plans the work of a transport enterprise when transporting general, dangerous, and oversized cargo along international roads. The task addressed is the need to compile recommendations for determining the required number of personnel and the duration of rendering transport services depending on the type of cargo received for service. A simulation model of the work of a transport enterprise when organizing international road transportation has been built and implemented in the GPSS World simulation modeling automation package. The model involves determining the duration of transport service and planning the personnel support for a transport enterprise according to the functional division of labor. When building the model, the duration of the types of work provided by specialists of the transport enterprise when transporting general, dangerous, and oversized cargo was taken into account. In addition, the model takes into account the probability of errors and delays at each stage of service. The average duration of the delay in the event of errors is also determined, which could make it possible to set additional time for engaging a separate specialist to eliminate them. The application of the devised model in practice would allow owners of transport enterprises to organize business processes depending on the available type of rolling stock. It could also make it possible to determine the optimal number of specialists of various profiles required for organizing transport services for the customer. At the same time, the duration of transport services for the delivery of various types of cargo will be reduced by 8–14% while the number of specialists of the transport enterprise – by 10–15%; in turn, the throughput will increase by 7–16%.
