A Dynamic and Discrete Berth Allocation Problem in Container Terminals Considering Tide Effects

This study aims to minimize vessels’ departure delay time at Shahid Rajaee (SHRA) shallow port of Iran. The problem of SHRA port is its low-depth channel; explaining that when the ebb happens, vessels with high draft are not able to pass through the access channel and thus have to wait for the flow. A mixed integer linear planning model, which is capable of considering tide effects in berth allocation problem, was utilized for the purpose of the study. Loading and unloading data of SHRA port’s current situation were compared with the model outputs to validate the model. The results showed that the proposed model can considerably reduce vessels’ delay time. Next, a sensitivity analysis was performed on the depth of the access channel. The results revealed that channel dredging can significantly reduce vessels’ departure delay time and improve the performance of SHRA container port. Finally, active and active–reactive procedures were suggested to consider parameters’ uncertainty. The findings indicated that active–reactive procedure outperformed active procedure.
