Abstract:
1. A parts production management system that sets a linking relationship between a parent lot number at an input port of a part producing production line and a child lot number at an output port of the production line, the parts production management system comprising: a first table in which a line cycle number representing a line cycle for processing a group of parts and a parent lot number of a part input for being processed in the 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 the part processed in the line cycle represented by the line cycle number are stored while being linked together; a lot linking unit that stores the line cycle number of the line cycle for processing a parent lot and the parent lot number in the first table while being linked together when the parent lot is input to the production line and stores the line cycle number of the line cycle that has processed the 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; and a line cycle management unit that acquires line cycle numbers corresponding to line cycles processing the groups of parts and stores the line cycle numbers, line codes specifying the production lines in which the line cycles corresponding to the line cycle numbers are operated, and start dates of the operations of the line cycles at which the operations of the line cycles are started in a line cycle table while being linked together when the groups of the parts are input to the production lines.
