Abstract
A transfer or production line utilizing a plurality of stations is described which has a computer at each station. Each computer has a part processing record for all workpieces currently in the line. As the workpiece transfers down the line, a part position index, contained in each of the station computers, is updated to indicate which part processing record is associated with the workpiece at each station. The information in the part processing record is utilized by the station computer to inhibit the station from cycling if the record indicates that a prerequisite had not been completed.
