ABSTRACT:
The invention relates to a method for monitoring and analyzing a production process. In the method, a large number of variables are measured from the process,with the aid of these variables, fingerprints according to a good and a poor process situation, relative to runnability, are defined in several sub-processes and are then stored in a memory,the stored fingerprints are compared with fingerprints obtained in a normal process situation,on the basis of the comparison, the difference, displayed graphically to the user, between the recorded good situation and the momentary process situation is defined.
