Abstract
An exemplary method of assigning calls to elevator cars includes ensuring that a passenger separation requirement is satisfied. The passenger separation requirement is satisfied when a passenger belonging to one service group is not carried in the same elevator car simultaneously with another passenger belonging to a different service group, for example. A call is assigned to an elevator car to carry a passenger belonging to the one service group while the elevator car is assigned to carry or is already carrying another passenger belonging to the different service group.
