A line production management system is provided. In the line production management system, a primary computer, a primary controller, a secondary controller, a tertiary controller and a number of processing machines are provided. The primary controller maintains work files containing work sequence data defining the classification, work priority and quantity of the work objects to be processed, and transmits the work file information through a communication network. The secondary controller generates and maintains correlation files to correlate each work sequence data included in the work files information with the codes which determine each processing to be applied to each work object in each work station, and transmits the correlation files through the communication network. The tertiary controller generates step files based on the work files and correlation files received through the communication network. The step files contain processing instruction data for each work station. In each work station, the processing machines are automatically controlled according to the processing instruction data received from the tertiary controller.
