<p>In a processing plant in which workpieces are conveyed to selected work stations according to a programme, the computer programme chosen for the plant operation and representing a simulated operating schedule is run through during the actual operation of the plant in synchrony with the latter. The plant comprises a number of sensors by means of which data on actual events taking place in the plant, such as the passage of the workpieces through certain sections of the plant, are recorded. These sensors allow the computer to compare the actual operation with the simulated operating schedule. In response to any discrepancy between the actual and the simulated operating data, an output signal initiates manual or automatic corrective measures.</p> |
