“…Further, new conceptual YCs that have recently been introduced include overhead bridge cranes that are being used in Singapore, two non-crossing rail mounted gantry crane (RMGC) in a block, two crossing RMGC in a block, and two non-crossing RMGCs with one additional crossing RMGC. New operational methods must be developed for the efficient operation of these new conceptual YCs (Kemme 2011(Kemme , 2012. Impacts of different yard layouts on the operational performance of the yard needs to be studies further (Petering 2013;Kim 2010, 2013).…”

This study reviews various planning and control activities in container terminals. Decision-making problems for operation planning and control are defined and new trends in the technological development for each decision-making process are discussed. Relevant research directions and open questions are proposed. The functions of the Terminal Operating System (TOS), which is the software used to implement the decision-making processes, are discussed and commercial TOSs are introduced and compared.

The growing demand for increased flexibility and throughput capacity of automated warehouses is driving the implementation of rail-guided automated vehicle storage and retrieval systems (AVSRSs). A new type of AVSRS is capable of further increased performance by utilizing multiple vehicles along one rail instead of using only a single vehicle per aisle and tier. In this work, we introduce the shuttle vehicle scheduling problem (SVSP) in AVSRSs and present methods to solve the SVSP. We conduct a series of simulation experiments to show the performance improvement of horizontal transportation in various configurations of this new type of AVSRS and discuss main benefits of deploying high-powered AVSRSs.

A note on scheduling container storage operations of two non‐passing stacking cranes

We study a scheduling problem for a container block, in which there are incoming containers only. Container placement is served by two non‐passing stacking cranes based at the opposite sides of the container block. The same time is required for any crane to move between two adjacent bays of the container block and the same different time is required for any crane to perform any down‐and‐up operation related to container lifting at the pick‐up point or container lowering at the storage point. Containers are assigned to the cranes according to one of the following policies: (1) two fixed sequences policy where a container processing sequence is given for each crane, (2) dedicated crane policy where containers are preassigned to the cranes, (3) one fixed, one arbitrary sequence policy where a container processing sequence is given for one crane and it can be arbitrary for the other crane, (4) flexible policy where any container can be assigned to any crane at any time, and (5) global fixed sequence policy where the container sequence is given and the relative processing order of containers in this sequence must be preserved by any crane. The objective is to minimize the completion time of the latest operation. We show that the problem is polynomially solvable for policy 1 and, if the number of containers to be placed in the same bay is no more than a half of all containers, for policy 4. It is NP‐hard in the strong sense for policies 2 and 3. Approximation algorithms with guaranteed absolute and relative deviations from the optimum are devised for policies 4 and 5. The results translate for the case of outgoing containers only.
