In 2023, exports between Ukraine and other countries underwent significant changes. Thus, Poland took first place in terms of the volume of exports from Ukraine in 2023 (more than 5.6 billion dollars or 15.4%). Instead, China, which was the No. 1 consumer of Ukrainian goods, fell to the 4th place in the ranking of top exporters during the war. Its share in total exports of Ukraine halved - from 11.8% to 5.3%.
The use of time slot technology is a modern technology for increasing the efficiency of cargo transportation in international traffic. The essence of the technology of time intervals is that the working time of the terminal is divided into time segments. During these time slots, terminal clients place their service requests. During the reserved time slot, the client's car must enter the territory of the terminal for service.
The introduction of time slot technology aims to provide the client with the possibility of guaranteed arrival of cars in a certain time interval, preventing crowding, long waiting and queue formation.
On the basis of the developed experimental plan, painted according to the determined maximum and minimum values of the arguments, the linear influence of factors on the time of cargo transportation was considered.
The R-squared coefficient is one of the most effective estimates of the adequacy of the regression model. In the case of a linear model without an independent variable, the R2 coefficient = 0.999, in the case of a linear model with an independent variable, R2 = 0.987, which means that the linear model without an independent variable is more accurate.
The obtained results indicate a more rational use of a linear model without an independent variable for determining the time of cargo transportation in the direction of Ukraine - Poland. As a result of the conducted experiment, it was established that there is a functional relationship between the inputs of the cargo transportation system in the Ukraine-Poland direction and the outputs.
