“…An important factor for ensuring the export of the Ukrainian grain is the effective logistic system of its delivery from producers in seaports, through which about 97% of the Ukrainian export grain is carried out (Kozachenko, D. et al, 2017). At the same time, it should be noted that the Ukrainian logistic system demonstrates rather a low efficiency now.…”

“…The main export streams of grain (about 63%) follow to seaports by railways (Kozachenko, D. et al, 2017). Ukrainian railways carry out about 90% of all goods turnover with a use of electric traction.…”

“…The choice of nodal elevators (stations) and formation on their base of concentration regions for grain loading represents a very complex multivariate and multiple-factor optimizing task. For solving of the specified task it is necessary to consider the existing infrastructure of stations and elevators, possibilities of their development, existing and expected volumes of grain loading, and also the additional expenses connected with storage of grain, loading of routes, delivery of grain to junctions by road transport, expenses on transportation of grain by railway transport to ports (Kozachenko, D. et al, 2017). Problem definition.…”

“…The task has the constraints: Constraint (12) means that each station st can be included no more than in one region of concentration * u R , however, it can be not included in the region. Constraint (13) defines that the total volume of grain loading for each region of concentration * u R has to be not less than Qmin (6), otherwise such region is excluded, and the stations belonging to it are redistributed between other regions. Constraint (14) excludes a possibility of the addition of station st to the region * u R , if it is not provided in an initial set of regions R. The task (11)-(14) represent a problem of multi-criteria optimization.…”

The research objective is to increase the efficiency of export railway transportation of grain freights in Ukraine by the introduction of consignor routing, a concentration of loading of grain on junction elevators and the organization of the movement of grain routes according to the schedule. According to the researchers in USA and EU, one of the effective directions for decreasing the expenses in a logistic chain of grain delivery to ports is consignor routing of railway transportation. Consignor routing of transportations of grain freights provides a concentration of their loading at junctions. The choice of junctions is proposed to be carried out on the basis of methods of the cluster analysis. For formation of regions for a concentration of grain loading the theory of sets and multicriteria optimization are used. As a result, on the basis of the modified simplex method are chosen 24 regions of possible concentration of grain loading that cover 70 stations on Ukrainian railways providing 7,5 million t consignor routing for grain in a year with minimal additional expenses. The assessment of the efficiency of railway transportation routing of grain freights is calculated with use of the developed simulation model. Researches showed that application of consignor routing allows to reduce a turn-round cycle for grain wagon in a logistic chain of deliveries up to 27%, and application of the schedule for consignor routes allows to reduce a turn-round cycle up to 62%, in comparison with transportation by car loading. Thus, as showed the calculations executed for one of the directions of grain transportation for export, the necessary operation park of grain-carrier wagons is reduced twice, thereby allowing to cut logistic expenses on a delivery of the Ukrainian grain through seaports to the world markets.

“…Основная часть зерновых грузов вывозится из Украины морскими судами, на которые приходится более 90 % экспорта. При этом доставка зерна в морские порты осуществляется по железным дорогам (61 %), автомобильным транспортом (36 %) и речным транспортом (3 %) [4]. Одним из существенных преимуществ перевозки зерновых железнодорожным транспортом для Украины является то, что около 90 % железнодорожных перевозок выполняется с помощью электрической тяги с использованием электроэнергии, генерируемой отечественными электростанциями.…”

The research objective is an analysis of the participation of the Black Sea Basin countries (Ukraine, Russia, Kazakhstan, Bulgaria and Romania) in world grain trade. We started this research before the start of Russia’s military actions in Ukraine, and completed it during these actions, so we have a vision of the situation before and after start of war. Subject of research: stability of grain supplies (wheat, corn, barley) from the Black Sea region as a whole and from some of its countries. Results of the research: The research revealed the growing role of the Black Sea region in the pre-war period in the world grain market and identified its key leaders. The share of the Black Sea region in world trade in wheat increased to 34%, barley – to 40,6%, corn – to 25,3% in 2019/2020 marketing year. The calculated coefficients of variation confirmed the decrease in the scattering of grain exports in 2015-2020 vs. 2010-2015, which indicates an increase in stability and reliability of supply in this period. The situation changed radically after the Russian invasion of Ukrainian territories. The maritime logistics corridors of Ukraine that is the one of the key players in this region, were blocked and started working only five months later, but not at full capacity. All these events had its destructive consequences for world trade, in particular, the increase in world prices, disruption of the stability of grain supplies from the Black Sea region and the destruction of established logistics corridors, etc.
