| Abstract | The need for automation in ports is growing, and a strategy gaining attention involves automating through retrofitting methods to enhance productivity while maintaining the flexibility of rubber-tired gantry cranes (RTGC) in the port. RTGCs offer greater flexibility than rail mounted gantry cranes (RMGC) as they are not fixed to specific container blocks and can move to adjacent blocks. Therefore, an operational strategy is required that can adapt to situations such as changes in the number of cranes for efficient operation. In this study, a score-based dispatching logic is proposed to efficiently allocate tasks for port yard cranes in real-time. In this logic, scores are calculated as the sum of appropriate weighted values for various factors, and tasks with the best scores are prioritized for execution. Comparing the performance metrics with other dispatching rules through AutoMod simulation, the superiority of the score-based dispatching logic is confirmed. Also, it is found that inter-block movements of RTGCs can improve key performance indicators in port yards, such as turnaround time. |
