The object of the study is a seaport as a transport hub with an internal infrastructure consisting of various departments whose actions are coordinated by the management system. It is noted that the introduction of information systems into the port management structure allows coordinating actions between port departments and external partners. The seaport is considered as a system consisting of subsystems, information about the state of which allows to streamline the processes of cargo movement, to carry out the activities of the port for a certain planning period and to make decisions in case of non-standard situations. It is noted in the paper that loading and unloading operations in the port are carried out by means of lifting and transport equipment, which has recently been produced with automatic and automated control. Attention is drawn to the fact that automated loading and transport equipment and related technologies for processing and tracking storage locations of processed goods contribute to improving the seaports efficiency. It is emphasized that the use of information technologies in seaports reduces the errors probability that may occur due to the human factor, contributes to the optimization of technological processes and reduces vehicle downtime. It is particularly noted that the development of information systems contributes to the integration of the cargo plan of the seaport with the shift-daily plan and the arrival of vehicles for processing, which allows for the operational management of the seaport. These data indicate that information resources are an economic value and act as one of the factors of seaport management. The information technologies used in the transport industry are considered and trends in the development of information systems of the port economy are identified in the paper. Based on the analysis of literary sources, it is concluded that the introduction of information technologies in ports contributes to increasing productivity and strengthening cooperation between interested parties in the transport sphere of activity. Smart ports will allow the port industry to interact with external enterprises with higher accuracy, openness and transparency, thereby improving relations and efficiency.

The seaport is a place for cargo transshipment and storage. The speed of vehicle processing is one of the indicators of port’s performance. The time of vehicles being under processing depends on the performance of a fleet of transshipment machinery. The stochastic nature of vehicles’ arriving leads to the intense operation of handling facilities and formation of wait lists for vehicles to be loaded or unloaded, or to the downtime of transshipment machinery when vehicles are absent. Depending on the operational situation, transshipment machinery is brought out for maintenance operations that can be performed by unit, which provides the increase in the technical use coefficient. For maintenance of individual units, the decomposition of handling facility is performed; statistical data on the time of maintenance conduction for all units is collected. Statistical data are entered into the database. When transshipment machinery is brought out of operation for a short period, the unit is selected, the service time of which coincides with the downtime of a brought out facility. To visualize the process of situational management of maintenance and define conflict situations, a simulation model was developed with the use of the apparatus of Petri nets. The analysis of the model helped to reveal conflict situations that can be solved both during situational management of transshipment machinery fleet and by means of models nested into conflict places.
