Destination Oriented Allocation System (DOAS)

The Destination Oriented Allocation System (DOAS) greatly enhances the operating efficiency of the elevator and shortens passengers' average waiting time. When a passenger enters a destination floor at a hall, the Destination Oriented Allocation System (DOAS) indicates which car will serve the floor. The passenger can wait for and board the car dispatched. When the car has arrived, the passenger does not need to press a button in the car because the destination floor is already registered.
