Owing that the internal trucks (ITs) are frequently used as transportation equipments between yards and quaysides, the transportation efficiency of ITs secures a crucial position in container terminal productivity. Hence, a container terminal cannot contain a big number of ITs. As such, it is an imperative to explore an appropriate IT assignment strategy.(More)
Container terminals mainly include three types of handling equipment, i.e., quay cranes (QCs), internal trucks (ITs) and yard cranes (YCs). Due to high cost of the handling equipment, container terminals can hardly purchase additional handling equipment. Therefore, the reasonable scheduling of these handling equipment, especially coordinated scheduling of(More)
This paper aims to propose an innovated design of automated container terminal (ACT) handling system, which can help the port to enhance the handling performance of the entire terminal. Different from conventional ACTs that use trucks or automated guided vehicles (AGVs) to transport containers in the terminal, the new handling system takes advantages of(More)
