Flexible Load Sequencing in Container Terminals

In this study, a method for estimating the quay crane (QC) operational time is used to determine the best loading sequence for containers. Detail parameters such as the distances to be traveled by the QC spreader in the horizontal and vertical axes, acceleration and deceleration rates, maximum speed of the spreader and hoist are considered. The objectives of this study include minimizing the total QC operational time and the number of relocations that occur in the yard during the container retrieval process. A tree search-based algorithm is used to find the best loading sequence. Numerical experiments are performed to find the acceptable width of the tree search, analyze the effect of each objective’s weight settings, and evaluate the proposed approach.
