A survey of the available container terminal data online by Wiese,
Kliewer, and Suhl (2009), also included in Wiese, Suhl, and
Kliewer (2011) found that RTGCs were used as the main stacking
MHE in 63.2% of the 114 container terminals studied. Automated
RMGCs are known as automated stacking cranes (ASCs). ASCs are
able to completely operate without human interaction as long as
they interact with automated transfer vehicles. However, if ASCs
are to interact with non-automated vehicles (e.g., external trucks),
the pickup (and deposit) moves from (to) non-automated vehicles
is done manually for safety reasons. Based on results from the
same study, Wiese et al. (2011) point out that 6.1% of the terminals
considered use automated RMGC (ASCs) most of which were located
in Europe. The (distant) second most used material handling
equipment (MHE) in the storage yard is the straddle carrier (20.2%,
see Wiese et al., 2011), shown in Fig. 2b. Straddle carriers (henceforth
referred to as SCs) are non-automated transport vehicles that
are capable of self-lifting and stacking containers. Given the selflifting
and stacking capability of SCs some container terminals
use them for both transferring containers between the quay and
the storage yard, and for storing containers in the yard.
