Abstract
An elevator control system includes one elevator control for each elevator car, one group supervisory device for each floor connected in two ways to the elevator controls, a group supervisory accessory connected to group supervisory devices, and a statistical device connected to the group supervisory devices and also to the group supervisory accessory. The group supervisory accessory calculates a car suspending time interval at each of the forward floors in a direction of travel of the elevator car in accordance with a percentage getting-off or -on from the statistical device by considering car and floor calls and the number of passengers within the elevator car increased due to non-responding floor calls and also a presumed arrival time interval at each floor. The group supervisory devices receive those presumed arrival time intervals to assign the optimum elevator car to the desired floor call through an associated one of the elevator controls.
