“…Надійна організація логістики постачання формується з використанням існуючих елементів інфраструктури транспортної мережі з урахуванням ризиків і збоїв [2,3]. Ресурси мають використовуватися більш ефективно, а логістична система має будуватися з одночасним використанням різних джерел постачання та з додержанням таких принципів доставки, як «гнучкість» і «саме вчасно» [4,5,6], оскільки це допомагає зменшити ризики відмови та проблеми в логістиці постачання товарів.…”

The article analyses the current state and prospects for developing logistics for supplying various types of cargo in international traffic to be transported in containers. It allowed us to formulate the purpose of the study in this development. This topic is relevant since the efficient organisation of containerised supply logistics can improve the functioning of transport systems. An effective way to reduce the cost of supplying a cargo unit is efficient resource use (railway stations, ports, warehouses, wagons, vehicles, containers). The study paid considerable attention to developing the relevant infrastructure, solving specific problems of efficient use of all types of resources, using digital technologies, and building reliable models of logistics supply systems. The article builds a structural model based on the principles of logistics interaction of possible participants in the supply process, representing the interaction of subsystems that significantly affect the quality of the relevant operations. We formed five schemes of interaction between logistics participants for supplying specialised vehicles in containers with the participation of automobile, railway, and sea transport and the relevant infrastructure. These schemes identify the main ports of departure in the United States (New York and Houston) and ports of destination in Europe (Klaipeda (Lithuania), Constanta (Romania)), and take into account the possibility of using road and rail transport resources in European countries and Ukraine. We developed a mathematical model of logistics functioning for the supply of specialised vehicles in containers from North American enterprises to Ukraine, which accounts for the specifics of sequential operations and the peculiarities of determining the performance indicators of each supply chain operation. The prospect of using these models is to build a simulation model of logistics for the supply of specialised vehicles in containers from North American companies to Ukraine, conduct simulations using a software environment, and determine the rational option under the established conditions. Keywords: model, logistics, supply, vehicles, international transportation.

The paper highlights the current state and prospects for logistics development of perishable goods supply in international traffic, which made it possible to justify the study aim in this research. The chosen topic is quite relevant because developing supplies to European countries have a real perspective according to last tendencies in the international perishable goods market. This fact is additionally justified by increasing delivery volumes of milk and meat products, and animal fats every year. One of the directions for supply logistics cost reduction is an efficient use of transport resources (vehicles, warehouses). The scientific projects and their results have shown that a well-developed market for transport services with appropriate operators and infrastructure allows effective logistics implementation for perishable goods delivery in international traffic to costs reducing for all supply chain participants. A structural model has been designed for the sequential interaction of logistics participants during perishable goods supply on routes from Ukraine to Poland, which is formed from certain participants implementing relevant operations. The sequence is designed based on order analysis of transport enterprises by cargo order volumes, transportation distances, operations cost, operations time, as well as statistical data of corresponding parameters. Three alternative options for the logistics of perishable goods delivery were formed, using road transport with various load capacities and warehouses. The designed schemes consider opportunities for using a consolidation warehouse in Ukrainian territory for a possible combination of products and involving a perishable cargo distribution warehouse in Poland territory. The operation costs of relevant supply logistics variants are selected as a criterion for evaluating proposed solutions. These costs are affected by: operations cost; the volume of perishable goods batch; transportation distances; shippers (consignees) quantity; operation time parameters. The mathematical models’ components for logistics of perishable goods supply have been designed according to alternative three options, considering performing operations specifics at each stage, as well as the peculiarities of cost and time determining for each operation performing in the supply chain. Keywords: sustainable model, sustainable logistics supply, perishable goods , international transportation.

“…Using traffic flow modeling is a cost-effective way of studying transportation, which allows for reliable predictions of delays and traffic congestion. The variety of traffic controlling options leads to using numerous criteria, making it possible to model and predict the sustainability of traffic flows and traffic jam conditions [2,3].…”

Assessing the transport flow robustness is a significant aspect of a qualitative solution to traffic management problems. Therefore, management should be based on appropriate criteria, accounting for different factors characterizing traffic flow sustainability. That’s why it is crucial to establish the impact rate for each group of factors on the robustness criterion. Therefore, the current study aims to obtain the dependence of the criterion changes for traffic flow sustainability on the traffic jam occurrence when changing the gradients’ product of traffic flow density and its speed. The value of the robustness criterion allows for performing an impact rating for input factors on traffic flow sustainability. All factors affecting transport flow robustness are divided into three groups. Based on simulation results, factors rating that impact the robustness margin value of the traffic flow is presented. Length and weight of automobiles are at first place according to impact terms on the sustainability loss of the traffic flow. In second place of impact on sustainability loss are the temporary factors group and factors group that considers the roadway environment’s infrastructure. Hence, the results can be used to analyze sustainability traffic flows in controlled highway network stretches and develop measures to increase sustainability reserve.
