A METHOD OF SUPERVISING OR CONTROLLING A DEVICE BY MEANS OF A COMPUTER MODEL

摘要

The invention concerns a method of supervising or controlling a real device (4) by means of a computer model (6) of the device. The real device (4) is operated (12) and the computer model (6) is run (14). The device (4) and the computer model (6) are thereby fed with (10) and/or execute the same data. Parameters concerning the state of the device (4) are registered (16). The corresponding parameters concerning the state of the computer model (6) are determined (18). The parameters concerning the state of the device (4) are compared (20) with the corresponding parameters concerning the state of the computer model (6). An assessment is done (22) whether deviations between said parameters concerning the state constitute normal deviations. At least one measure is carried out (28-34) when a non-normal deviation is detected.
