Destination Based Dispatching
ETA and DBD dispatching are available. ETA (Estimated Time of Arrival) dispatching is
designed to minimize average hall call waiting times. When a new hall or car call is registered,
all hall calls are evaluated to determine the optimum car assignment to minimize waiting time.
With DBD (Destination Based Dispatching) passengers enter their destination floor and are
assigned a specific elevator. The time from destination entry (source) to when the car reaches
the destination floor is called Journey time. The goal is to minimize the average journey time
for all known passengers, primarily by grouping passengers traveling to the same destination.
An iCentral dispatcher is required for Destination Based Dispatching.
In addition to the standard dispatching bonuses and penalties, DBD applies a coincidence
bonus for source and/or destination floors that share a common stop. The DBD engine also
considers the additional time and space required to accommodate Special Access passengers.
Dispatcher related DBD parameters are found on the following System > System Configuration
> Destination Based Dispatching tabs. Most car-related DBD parameters are set on the Control-
ler > Configuration > Destination Based Dispatching tabs. Please refer to “Configuration - Des-
tination Based Dispatching” on page 9-95.
