wherein a first display mode having a first setting is assigned to that of the at least two elevators in the shuttle mode having the highest rank in the preference order, and at least one second display mode having a setting being different to the first setting is assigned to the others of the at least two elevators in the shuttle mode.

11. A device configured to monitor a plurality of elevators, wherein at least two of the plurality of elevators are set into a shuttle mode in which the corresponding elevator travels between two pre-defined floors, the device including

memory storing an elevator monitoring program; and

a processor configured to access the elevator monitoring program and perform:

calculating at least one of an arrival time and a departure time of an elevator car of each of the at least two elevators in the shuttle mode at a predetermined floor;

determining a time required by a user for reaching each of the at wo elevators in the shuttle mode from an operation terminal location;

calculating a preference order of the at least two elevators in the shuttle mode on the basis of the time of arrival and/or departure of the elevator car of each of the at least two elevators in the shuttle mode and the time required by the user for reaching each of the at least two elevators in the shuttle mode from the operation terminal location;

assigning one of a plurality of display modes to each of the at least two elevators in the shuttle mode according to the preference order; and

causing displaying of an elevator identification according to the preference order by using the assigned display mode.

12. An elevator system including

a plurality of elevators, wherein at least two of the plurality of elevators are set into a shuttle mode in which the corresponding elevator travels between two pre-defined floors;

at least one operation terminal including a display for displaying information related to the at least two elevators in the shuttle mode;

a controller configured to

calculate at least one of an arrival time and a departure time of an elevator car of each of the at least two elevators in the shuttle mode at a predetermined floor;
