 Organization of transportation significantly affects the performance indicators of logistics systems. Therefore, more and more attention are paid to the development of organizational and managerial measures, the implementation of which helps to reduce delivery time, to ensure their reliability at an economically viable total cost based on digital technologies.
Automated management of the entire transport and logistics system of the port is becoming a mandatory requirement to ensure high-quality logistics in the supply chains. It is the precise organization of the logistics process that contains significant resources to reduce costs, increase speed, as well as reliability and quality of supply chains, but without the synergy of logistics and information technology, this is not possible.
The aim of the study is to increase the efficiency of the seaport and the provided port services by coordinating the flow processes formed by all participants in legal relations arising in the process of transshipment and processing of cargo in the seaport. In the formation of the reliability and quality of transport services, to which port services can be fully attributed, basically two methodological approaches are used: a process and a system approach.
The article focuses on the role and importance of seaports, as well as the formation of the quality of port services based on the application of the process approach. A classification of port services is proposed, which implies a wider list of classification features that consider the role and place of port services in the technological process of port operation. The analysis of the main technological processes associated with the passage of state control procedures in the seaport. The necessity of developing a unified network technological process of the seaport is identified and the principles of its formation are described.
The results of the study allow us to conclude that the interaction between all participants in the technological process of cargo handling in the seaport is low, which negatively affects the quality of port services and the competitiveness of the port. The development of a unified network technological process of the seaport will allow us to systematize the main processes of the seaport and to reveal the systemic links between them, which ensures stable and efficient operation of the port, as well as the interaction between the flows of information, cargo and transport.

 In the logging process, it is possible to build a technological chain in various ways. When transporting wood from the cutting area, water or land transport can be used. The use of forest warehouses and the processing of wood on them also increase the number of different configurations of logistics channels. Performing operations in different natural production conditions differs in productivity and material costs. The efficiency of production depends on the choice of logging technology in dynamic natural production conditions. In previous publications the authors presented a graphic-analytical model and method to solve the problem. The proposed mathematical dependencies allow us to search for the maximum material flow of the minimum cost in the logistics network of the enterprise. In addition to the dynamic component, the method differs by considering the income of the enterprise from the sale of commodity products. The purpose of this study is to use this technique to improve the logistics network of logging enterprises, considering the complex of transport, loading and unloading and processing operations in dynamic natural production conditions. The solution of the considered problem is based on the algorithm for determining the flow of minimum cost in a transport network Bascara of Gowan. It is modified because when the flow passes through any of the arcs, the throughput of arcs that reflect similar operations in the same period decreases. This considers the reduced productivity of machines and equipment involved in different parts of the logistics network. The given minimum cost flow found in this way is optimal if there are no negative cycles in the network with modified arc costs. The presented studies consider a numerical example of solving this problem for the conditions of the Krasnoyarsk territory. The numerical example showed the efficiency of the method of finding a rational logistics channel for logging operations in dynamic natural production conditions.
