Optimized Design of Container Terminal Yard Space Allocation Based on Clustering Idea

Based on the idea of clustering and considering both import and export containers, we research the container yard storage space allocation problem under the dual-cycle transportation mode, establish a mixed-integer planning model for the yard space allocation of container yard with the goal of maximizing the yard space utilization, and transformed it into a two-dimensional bin packing problem to be solved with an adaptive best-fit algorithm. The numerical results show that under different yard layout scales, the utilization rate of yard space is higher in dual-cycle mode than in single-cycle mode, which provides effective reference suggestions for further solving the bottleneck faced by container ports.
