Abstract (English):
The subject of the article is to optimize the process of assessing the instantaneous state of ship cargo terminals that are part of a transport hub and the dynamics of their changes in a short-term period of time. Modern cargo operations management systems use for this purpose software and hardware complexes that calculate the current load of a transport node in the form of a system of parameters characterizing the degree of workload of all its constituent elements. The disadvantage of this approach is the need to use powerful numerical tools, and the complexity of assessing possible development scenarios in the presence of a number of random factors. The purpose of the article is to develop a method for assessing local changes in the energy model of a transport hub, which allows solving problems of optimizing the operation of dry cargo terminals in a stochastic system of a transport hub. The novelty of the conducted research lies in the use of the method of analogies between the processes occurring in the transport node and thermodynamic systems, which makes it possible to quickly analyze random changes in the state of the transport node using relatively simple computing programs. The result of the presented work is an algorithm for optimization and selection of the most preferred alternatives for the distribution of ship cargo terminals in the transport hub system
