Improving the mechanism of port handling complexes

The issue of modernization of cargo flow mechanization schemes, while optimizing logistics costs with the aim of increasing port capacity, was considered. The process of cargo transshipment using various lifting and transport machines is studied, the schemes of complex mechanization of port terminals are presented. The main schemes of complex mechanization in the port are analyzed on the example of transportation of artificial cargo - slab. The leading link of these schemes is the gantry crane, for which a dynamic 3D model has been developed, which allows you to create a scenario of the transport operation using simulation systems. With the help of the simulator, it is possible to evaluate indicators of performance and reliability of the crane. The results of the calculations of the characteristics of the warehouse, its capacity and the layout of the slabs are given. To build a logistics algorithm for cargo transportation operations, input data (structure of freight traffic, energy costs, logistics costs), objects (lifting and transport equipment, ships, railway transport) and output information in the form of a report with simulation results are determined. The paper proposes an algorithm for the simulation model of the port transshipment complex, which allows you to visualize the technological process of transshipment operations and optimize the parameters according to the specified quality criteria. The materials of the article can be useful to specialists of the mechanization services of sea and river ports, as well as used in the educational process as tasks for laboratory, practical and course work
