ENG: The object of this study is the process of goods delivery in international road transport using various types of logistics chains. The problem being solved is due to the need to develop recommendations for exporters of goods to reformat or design new supply chains during wartime. The expediency of organizing foreign trade operations by the cargo owners' own forces or with the involvement of enterprises providing logistics consulting services is considered. A simulation model of goods delivery in international road traffic was built and implemented in the GPSS World simulation automation package. The model involves the optimization of organizational and technological processes related to the activity of both a separate link and the entire supply chain. The study takes into account the components of the time characteristics of the performance of preparatory work when establishing cooperation with institutions and organizations, as well as the direct service of the exporter. The application of the developed model in practical activities will provide an opportunity for exporters to obtain information about the duration and reliability of the stages of a foreign trade operation and the feasibility of involving consulting enterprises in cooperation. At the same time, the simulation results reflect the performance indicators of the proposed supply chains when delivering goods by road transport along various routes. The proposed simulation model will make it possible to reduce the time spent searching for links in the formation of a supply chain by 8–12 %, and the duration of a foreign trade operation by 10–14 %. Thus, the reliability of cooperation with intermediary organizations will increase by 8–11 %.

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%.

ENG: The object of this study is the process of planning the work of a manufacturing enterprise that needs transport and forwarding services when exporting goods to counterparties in different countries of the world.The problem being solved is predetermined by the need to devise recommendations for choosing a transport and forwarding company when serving an individual customer, based on its individual needs and conditions of cooperation. A simulation model for the selection of a transport and forwarding company was constructed and implemented to meet the customer’s needs when exporting goods, applying the GPSS World simulation automation package.The model provides for the optimization of the choice of a transport and forwarding company for servicing counterparties based on the assessment of their activity indicators over previous periods of cooperation. When building the model, the types of commercial conditions of the exporter’s cooperation with the transport and forwarding company, indicators of the quality assessment of the basic level of service and the duration of service at all stages of the foreign trade operation were taken into account. The application of the constructed model in practice will enable exporters and importers to choose a transport and forwarding company depending on the individual needs of customers in the delivery of goods. The simulation results reflect the performance indicators of the provision of transport and forwarding services by various specialized enterprises. This will make it possible to involve in the transport and forwarding service of a separate counterparty an organization that will meet all the requirements of goods buyer in accordance with the terms of the international economic contract. At the same time, the duration of choosing and agreeing the terms of cooperation could be reduced by 12–15 % while the efficiency of transport and forwarding services would increase by 13–16 %.
