Abstract (en)
[origin: WO2021038079A1] The present invention relates to a device and to a method for analyzing a sequential process, the sequential process having at least one repeating sub-process, and the method comprising the following steps: a. recording process data of the sequential process over a reference time period; b. automatically determining phase limits on the basis of the recorded process data; c. identifying at least one repeating sub-process, the duration of which is limited by two adjacent phase limits; d. determining at least one reference variable for each identified repeating sub-process from the process data recorded in the time period; e. recording process data of the sequential process over a time period following the reference time period and repeating steps b. and c. in order to detect the recurrence of an identified sub-process; f. comparing the recorded process data of the detected sub-process with the at least one reference variable of the corresponding identified sub-process in order to ascertain deviations from standard operation.
