Destination dispatch

Destination dispatch is an optimization technique used for multi-elevator installations, which groups passengers for the same destinations into the same elevators, thereby reducing waiting and travel times when compared to a traditional approach where all passengers wishing to ascend or descend enter the same lift and then request their destination.

Using destination dispatch, passengers request travel to a particular floor using a keypad, touch screen or proximity card room-key prior in the lobby and are immediately directed to an appropriate elevator shaft.

Algorithms[edit]

Based on information about the trips that passengers wish to make, the controller will dynamically allocate individuals to elevators to avoid excessive intermediate stops. Overall trip-times can be reduced by 25% with capacity up by 30%.[1]

Controllers can also offer different levels of service to passengers based on information contained in their key-cards. A high-privilege user may be allocated the nearest available elevator and always be guaranteed a direct service to their floor, and may be allocated an elevator with exclusive use; other users may be provided with extended door-opening times.[2]

Limitations[edit]

The smooth operation of a destination dispatch system depends upon each passenger indicating their destination intention separately. In most cases, the elevator system has no way of differentiating a group of passengers from a single passenger if the group's destination is only keyed in a single time. This could potentially lead to an elevator stopping to pick up more passengers than the elevator actually has capacity for, creating delays for other users.[citation needed]

Manufacturers[edit]

Elevator manufacturers that offer destination dispatch include Otis Elevator, Kone Corporation, ThyssenKrupp, Schindler Group, Fujitec, Mitsubishi and Motion Control Engineering.
