Booming the global container trade, scarcity of land at ports in many metropolitan areas has the same difficulties with expanding the terminal area to improve capacity. As a result, alternative solutions, high-density, Automated Container Terminals (ACT) are currently considered to increase the performance of container terminal. In this paper, a concept of New Combination system-ACT (NC-ACT) is proposed. The average percentage cost per container and land needed is analyzed, evaluated, and compared with four prior systems. Four prior systems include general ACT (AGV-ACT) using Automated Guided Vehicles (AGVs), Linear Motor Conveyance System (LMCS), overhead Grid Rail system (GR), and Automated Storage/Retrieval System (AS/RS). NC-ACT is shown that the efficiency is higher, the capacity is higher, unchecked containers are accessed randomly, and it has lower average percentage cost/ storage capacity/acre than four prior ACT systems.
