Abstract. Optimization of the network of transformation centers is one of the conditions for the effective functioning of the macro-logistic system. Acting as links in logistics chains, transformation centers perform the most important functions of promoting material flows between the elements of production processes, commodity circulation and consumption. The article studies and reveals the role of transformation centers, which implement the most important tasks of mutual cooperation of trunk and local modes of transport.  The stages of logistic approach in choosing the variant of transformational centers location have been investigated. It has been determined that the transformation centers, being the basis for the creation of macro-logistic transport and storage systems of the corresponding level, perform the functions necessary to smooth the unevenness, inaccuracy of production, consumption and modes of transport turnover. The logistic concept which assumes the necessity of transformational centers as transport terminal complexes, warehouse complexes to create positive results of interaction of factors characterizing optimization of processes of advancement of material flows in logistic chains has been analyzed.  The results of the study showed that in maritime transport, the main factor in the development of transport container terminals, as varieties of transformation centers - is the formation of complexes of means of transportation of centralized systems of movement of goods.  Currently, the system of container transportation is among the most rational methods of technology and organization of multimodal cargo transportation. The concept of this system is based on the fact that it is proposed to transport cargo flows in a single cargo unit-capacity mixed modes of transport. In the conditions of functioning of the local transformation center, in addition to the implementation of complex logistical operations for the processing of material flows, operations for the development of preparatory processes of products for production consumption in the end are performed. This determines the representation of transport and warehouse systems of transformation centers as varieties of flexible production and logistics systems.

Key words: transformation centers, material flow, transport and storage system, logistics chain, container terminal, automated container terminal management systems.

Abstract. The article assessed the effectiveness of laser surfacing technology designed to restore metal parts subject to high wear, dynamic loads and mechanical influences during operation. Laser surfacing, as a new technology based on the use of lasers and nanomaterials to harden alloys, is an effective method of restoring worn parts or improving the strength characteristics of new mechanisms and machines. This technology allows the material to be precisely applied to the surface of the parts, which ensures high accuracy and quality of restoration. As a result of the use of laser surfacing, it is possible to significantly increase the service life of parts and ensure their reliable operation under conditions of increased operational load. This makes this technology in demand in various industries where high wear resistance and strength of parts and mechanisms are required.

Additionally, laser surfacing is characterized by high efficiency and cost-effectiveness of the parts restoration process. Due to the possibility of using a variety of materials and precise control of the application of a layer of material to the surface, this technology minimizes waste and reduces production costs. Moreover, laser surfacing is capable of restoring not only surface defects, but also improving the mechanical properties of the material, which increases its strength and durability. Thus, the use of laser surfacing in production promises significant benefits, including increased resource efficiency, reduced maintenance costs and improved quality of the final product.

Keywords: strength characteristics of parts, laser surfacing, thermal effects, laser installations, lasers, nanomaterials, life of parts.

Annotation. In maritime logistics, automation of seaports performs the most important functions to ensure stable high growth in international shipping volumes and strengthen competitive and price pressure in the business of shipping companies. The article provides a comprehensive assessment of the effectiveness of the automated Container Terminal Management System (CTMS), designed to automate the management of the container terminal and all operations with containers and cargo.  It has been established that CTMS, in comparison with the automated container site management system (ACS MS), has a number of advantages in accelerating the turnover of containers at the terminal by optimizing storage locations and the possibility of operational control over the operation of the terminal. The possibilities of a significant increase in the speed and accuracy of container cargo handling using CTMS have been identified. The main directions of effective functioning of CTMS are defined, taking into account the fact that all operations controlled by it are carried out using mobile data collection terminals. Their use when performing operations in a warehouse allows you to reduce the number of errors, the time of operations, and provides the opportunity to obtain accurate information in real time.

Keywords: Automation of management, container terminal, containers, container turnover, storage, loading, personnel management, operational control

Abstract. This paper investigates in detail the aspects of supersonic gas jets application in the process of thermal destruction of rocks. The main attention is paid to various aspects of heat transfer, which is key in the use of such methods. The main thermodynamic parameters of a high-intensity gas heat carrier in interaction with rocks are considered. Important characteristics are the heat transfer coefficient from the gas jet to the rock, the effective gas temperature at the rock surface and the specific heat flux. In order to achieve a more accurate mathematical description of the process of thermal destruction of rocks, the authors present a model of the interaction between the gas jet and the rock. They draw attention to the importance of the correct choice of geometric and thermal modeling parameters. Particular attention is paid to the stress-strain state of the rock under the influence of the gas jet heat flow, which is a key aspect in analyzing the efficiency of the fracture process. Various methods and parameters affecting the efficiency of heat exchange between the gas jet and the rock are also analyzed. An elastic half-space, which is a rock interacting with an external high-temperature medium, is considered. Heat exchange occurs according to the law of convection, and the maximum parameters of heat exchange from the jet to the rock are in the vicinity of the central point of its spreading at braking on the rock surface. The stress-strain state of the rock under the influence of the gas jet heat flow is investigated.

Key words: thermal tool, in-chamber pressure, fire-jet destruction, rocks.
