An algorithm dispatches a series of cabs in a passenger conveying system of the type wherein there are at least four cabs moving between two floors. One cab is positioned at each floor at all times, and a cab is moving to each floor at all times. A control monitors the actual position of the cab, and compares the actual position to a desired position. If the desired and actual positions differ, then the control modifies a cycle time for at least some of the cabs to move the cabs closer to the desired position. In one embodiment, the four cabs are provided in two sets of paired cabs. The paired cabs move in direct opposition to each other. Preferably, the correction in the monitored/desired position of the cabs is made by changing the time period for which the doors are held open when the cabs are at a floor. |
