The invention relates to a method for monitoring and analysing 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 the 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.
L'invention concerne un procédé de surveillance et d'analyse d'un processus de production. Dans le procédé, un grand nombre de variables sont mesurées à partir du processus. A l'aide desdites variables, des empreintes digitales selon une bonne ou une mauvaise situation, en ce qui concerne l'exécutabilité, sont définies dans plusieurs sous-processus et sont ensuite stockées dans une mémoire. Lesdites empreintes digitales stockées sont comparées aux empreintes digitales obtenues dans une situation de processus normale. Sur la base de la comparaison, la différence, apparaissant graphiquement à l'utilisateur est définie entre la bonne situation enregistrée et la situation de processus momentanée.
