Abstract

The present invention provides a method and apparatus for use in elevator systems for assigning new hall calls to one of a plurality of available elevator cars. According to the invention, a call cost is calculated for each car for accepting the new hall call. The call cost is a function of the estimated time to the desired destination of the passenger requesting the new hall call and of the delay that other passengers who are using the elevator car will experience. In one embodiment, a destination is inferred for the passenger requesting the new hall call. In another embodiment, the passenger requesting the hall call may input a desired destination at the time the hall call request is made. The elevator system of the present invention allows for use of both standard up/down hall call entry devices and destination entry devices that allow a particular destination to be entered by a passenger at the time a hall call is requested.
