Abstract
An exemplary method of controlling an elevator system includes determining that a new passenger requests elevator service from a departure floor to a destination floor. Any candidate elevator cars are ranked. A number of stops for each assigned passenger for a ranked candidate elevator car is determined if the new passenger were assigned to that car. A determination is made whether any ranked candidate elevator car is a qualified car that can accept the new passenger and limit a number of stops for each passenger assigned to that car to a desired maximum number of stops. The new passenger is assigned to a qualified car that has a most favorable ranking of any qualified cars.
