Control methodology of transfer crane with look-ahead rule in harbor transportation system

Abstract

Currently, container ships move cargo with minimal participation from inland chassis trucks. However, there is slack time between the departure of container ships and the completion of cargo handling of container ships without the participation of inland chassis trucks; therefore, inland chassis trucks can be used to move cargo without delaying the departure time. In this paper, we propose a solution involving the control algorithms of transfer cranes (TC). The TCs work according to the heuristic rules with look-ahead to forecast the arrival times of yard and inland chassis trucks. Simulation results show that the waiting time of inland chassis trucks can be reduced to meet the departure times of container ships.
