Abstract: A parts production management system includes: a first table in which a line cycle number representing a line cycle that is a process unit for processing a group of parts and a parent lot number of a part input for being processed in a line cycle represented by the line cycle number are stored while being linked together; a second table in which the line cycle number and a child lot number of a part processed in the line cycle represented by the line cycle number are stored while being linked together; and a lot linking unit that stores a line cycle number of a line cycle for processing a parent lot and a parent lot number in the first table while being linked together when the parent lot is input to a production line and stores a line cycle number of a line cycle that has processed a child lot and the child lot number while being linked together when a process in the production line is completed and the child lot is output from the production line.
