Abstract
Elevator door dwell time is varied as a function of arrival time so that a show-and-go time is met. The show-and-go time is the time from when the passengers are shown which elevator to board to the time when the elevator door is ready to close after the pasengers have entered the elevator. The arrival time is a function of the distance of the elevator from the floor of the hall call signal and is the time remaining after an elevator reaches a stop control point where a hall call assignment is fixed to a car until the door of said elevator begins to open. Door opening time, door dwell time, and arrival time are subtracted from a show-and-go time. If the difference is greater than or equal to zero, the door dwell time is increased by the difference, but if the difference is less than zero the door dwell time is decreased by the difference, and the doors are then held open at a landing for the door dwell time.
