Abstract
The solutions for rail yard digital twin design based on simulation modeling are presented. Simulation models in railway transport are traditionally used as a tool for substantiating design decisions. Operational management of railway transport based on simulation models requires solving the problem of adjusting model parameters using information system data. An approach to the design of an Industrial Rail Yards Digital Twins (IRYDT) is proposed, based on the use of the track plan digital sub-twin and the rail yard operation technology digital sub-twin as subsystems of a rail yard's simulation model. The design features of each sub-twin are shown. The main functional modules of IRYDT are presented, which include data synchronization, decision making, and training modules. An original algorithm for synchronizing the IRYDT with actual data has been developed. The results of a comparative analysis of various approaches to creating rail yard digital twins are presented.
