STUDY OF INTERACTION OF AUTOMOTIVE AND RIVER TRANSPORT AT THE PORT TERMINAL BY THE METHOD OF SIMULATION

Abstract

The aim of the study is to improve the technology of interaction between road and river transport on the territory of the port. The object of research is the port handling fronts; the subject of research is the technology of servicing various types of transport on the territory of the port terminal. Research methodology - simulation. The result of the study is an analytical assessment of the work of inland waterway transport for the carriage of goods, which indicates the absence of an integrated approach to improve the interaction of various modes of transport on the territory of the port terminal. Therefore, it is proposed to search for a rational technology based on simulation methods, which can reduce the time of non-production downtime. Competent organization of reloading from road to river transport and vice versa provides for the creation at the cargo terminal of such a traffic control system that provides collection and storage of operational information about the location of vehicles on the cargo fronts of the port terminal, the state of loading and unloading mechanisms, and allows making decisions on their use and transmitting commands to car drivers in order to improve the efficiency of interaction between road and river transport during cargo transshipment. For the proposed technology, the time for transshipment of cargo and idle time of vehicles under unloading was calculated using the theory of queuing systems. Counting the idle time of vehicles in various disciplines of choosing the cargo front (random or adjustable mode) made it possible to select the optimal system for regulating the approach of vehicles to the cargo fronts of the port terminal. The expected economic efficiency due to the reduction in the time of transshipment of goods from one mode of transport to another, according to the results of calculations, is 20,5 thousand EUR. The scientific novelty lies in the theoretical substantiation of various technologies for the interaction of road and river transport on the territory of the port terminal. At the same time, the problem of determining the optimal control system for the delivery of vehicles of the cargo fronts of the port terminal, on which reloading to river vessels occurs, has been formalized and solved using the methods of simulation modeling. This allows to reduce the downtime of transport units and more efficiently use the loading and unloading mechanisms, and, consequently, to reduce cost indicators. Practical significance: the proposed technology can be introduced into the technological processes of large river port terminals, where various types of transport interact. The simulation results are recommended to be used by the dispatcher staff when planning to bring vehicles to the berthing cargo fronts.
