Abstract
A system for preparing manufacturing-process specifications employs process data serving both for a production control system and a simulation system, and effectively uses a result of simulation. The system prepares the manufacturing-process specifications through the steps of controlling apparatuses according to the manufacturing-process specifications, to carry out manufacturing processes; collecting data measured through the manufacturing processes; simulating the manufacturing processes according to corresponding models and parameters; correcting the models and parameters according to the collected data; and amending the manufacturing-process specifications according to a result of the simulation.
