ABSTRACT:
A system for managing successive processes which are to be performed on raw articles in a production line for producing finished articles. The system comprises a process managing block for receiving data on preceding processes which have already been performed on partially finished articles on the production line and delivers conditions for the processes which are to be subsequently performed on the production line, a data accumulation block for statistically accumulating data concerning preceding processes carried out on the production line, and a simulation block for determining optimum conditions for the processes which are to be subsequently performed based on the data concerning the preceding processes which have been actually performed on the production line and the statistical data accumulated on the data accumulation block. The simulation block provides optimum process conditions to the process managing block. Any deviation of the characteristics of the unfinished product caused by preceding processes are compensated for by appropriately varying the conditions of the subsequent processes whereby finished articles of high quality are produced with a high yield.
