Estimation of efficiency of work of transport and technological systems of sea ports under conditions of drainage of loads

The article analyzes the existing approaches to the strategic development of Ukraine’s maritime transport, including the infrastructure of seaports under conditions of deregulation of their work. The formation of the necessary conditions for a balanced, rational development and deployment of the transport infrastructure, the elimination of the existing imbalances between it and other sectors of the economy require the development of its strategy for the medium and long-term time horizons. The implementation of the development strategy and location of the transport infrastructure in order to solve the problem of complete, timely, uninterrupted and high-quality satisfaction of the rapidly growing demand of consumers of services with possible minimum costs will require its priority, advanced and accelerated formation in relation to the economy as a whole and its individual sectors. Ports are the most important points of transshipment of cargo to sea transport from adjacent regions and the country as a whole. The peculiarity of the work of the transport and technological complex of the seaport in modern technical, economic and political conditions is that it works mainly in view of the increased deregulation according to the nomenclature and the number of transported goods. The peculiarities of the work of seaports of Ukraine in the conditions of deregulation are studied using the example of the Mariupol port of the Eastern region of Ukraine for transportation of various types of cargo. A graphic model demonstrating the changes in the main port performance parameters was constructed depending on the influence of various conditions and factors. The complexity of the work of seaports lies in a certain “unpredictability” of the nomenclature and volume of logistic flows of goods and the requirements of consumers, not fully dependent on the specialization and areas of work of the ports. In the study of this problem, the zones of deregulation of the volumes of cargo flows passing through the seaports of Ukraine were determined, the influence of deregulating factors on their competitiveness was described. The analysis showed that changes in the nomenclature and volumes of cargo traffic have a significant deregulation effect on the operation of the transport infrastructure of the seaport, and with a significant level of cargo traffic it is necessary to take into account, including the seasonal factor. When assessing deregulation changes in seaport traffic, measures to change the load on its transport infrastructure should be developed in accordance with a specific area of border change, i.e. infrastructure spending increases or decreases accordingly. This will allow you to choose a rational direction to increase the efficiency of the entire transport and technological system of the port, improve the state of the port infrastructure and increase the competitiveness of the Eastern region of Ukraine. The method of mathematical analysis determines the limits of deregulation of the transport and technological complex on the example of the Mariupol sea port, depending on different performance indicators, directions and range of cargo traffic according to long-term, more than 12 years, observations. The area of change in the limits of the deregulation of cargo flows has been determined, which makes it possible to adjust infrastructure costs accordingly and increase the competitiveness of the seaport.
