<p>PURPOSE:To obtain the data prediction device equipped with a high-precision correcting means by providing the correcting means which corrects a predicted value of next data by using an index smoothing method, and adaptively updating the weight of the index smoothing method. CONSTITUTION:A 1st predicted value found by a prediction means 31 is inputted to the correcting means 32, which corrects the 1st predicted value by using the index smoothing means to obtain a 2nd predicted value. A rolling condition setting device 20 decides whether or not this predicted value is equal to a desired value, chances rolling conditions when their difference is still large, and sends the changed rolling conditions to the data prediction device 30 again. Once the second predicted value matching the desired value is obtained, the rolling conditions are set in a rolling process 10. Thus, the correcting means makes corrections by using the weight which is updated adaptively in sequence to make the sufficient corrections following variation of a system even if the actual system has the variation.</p> |
