Abstract
A traffic management system for an automatic material handling system (AMHS) divides time into a series of discrete time periods and analyzes a plurality of move requests that are to be executed within a particular time period is disclosed. The traffic management system receives a plurality of move requests from the AMHS and determines how many move requests are to be executed and selects which move requests in particular will be executed in the next time period. The traffic management system prioritizes the selected move requests by analyzing each source node and destination node contained in a move request in conjunction with other node traffic data. The traffic management system analyzes this data to ensure that a move request is not executed if a material transport vehicle would be dispatched to a node having a node traffic balance value that exceeds a predetermined value and a node traffic density value that exceeds a predetermined value.
