Many algorithms that solve optimization problems are being developed and used. However, large and complex optimization problems still exist, and it is often difficult to obtain the desired results with one of these algorithms alone. This paper applies tabu search and ant colony optimization method to the container load sequencing problem. We also propose a(More)
We propose a noise-tolerant genetic algorithm (NTGA) to be used for deriving a policy for container stacking at an automated container terminal. The evaluation of a candidate stacking policy is inevitably noisy because an accurate evaluation requires too expensive simulations of crane operations at the stacking yard under various scenarios. Although the(More)
