Abstract
A method of assigning destination calls to cars (A-F) in an elevator system (20) having a plurality of hoistways (21-23) in which there is more than one car in each hoistway includes determining (33) the time for each car to respond to the call Among the cars with an acceptable response time, a determination is made regarding (34) the amount of additional delay in the hoistway that assignment of the call to one car will impose on the either car in the same hoistway. The call is assigned to that car which creates the least additional delay for cars in any hoistway.
