Abstract
An article handling system comprises closed loop pathways, movable carriers adapted to travel along the pathways, a plurality of article storage buffer stations located adjacent to the pathways, and a hierarchical control system for controlling the transfer of articles to or from a given one of the article storage buffer stations by a movable carrier. The buffer stations provide distributed article storage which allows the system to operate with enhanced speed and efficiency.
