Abstract

To control technical equipment (110) that performs a production batch-run (220) of a production process (200), a controller module performs a method (700) in that it accesses a reference time-series (*R*(1), *R*(2)) with data from a previously performed batch-run. The reference time-series (*R*, *R*(1), *R*(2)) is related to a parameter (660-1, 660-2) for the technical equipment (110). While the technical equipment performs the production batch-run (220), the module receives (720) a production time-series (*P*) with data, identifies (730) a sub-series (*R*(1)A, *R*(2)A) of the reference time-series (*R*, *R*(1), *R*(2)), and compares (740) the received time-series (*P*) and the sub-series (*R*(1)A, *R*(2)A) of the reference time-series. This results in an indication of similarity or non-similarity. In case of similarity, the module controls (750) the technical equipment during the continuation of the production batch-run, by using the parameter (660-1) as control parameter and/or by indicating a parameter from the reference time-series as a recommendation to the operator.
