A Critical-Shaking Neighborhood Search for the Yard Allocation Problem

Andrew Lim, Zhou Xu

The Yard Allocation Problem (YAP) is a real-life resource allocation problem faced by the Port of Singapore Authority (PSA). To overcome its NP-hardness practically, we propose an effective heuristic procedure, named critical-shaking neighborhood search, to solve the problem. Extensive experiments show that the new method can produce solutions with higher qualities in a much shorter time, as compared with other heuristics proposed in the literature. Further to this, it also improves or at least achieves the best solutions to all the benchmark instances of the problem.

Keywords: port logistics, planning, scheduling, packing, heuristics, automation
