<p>A method for tracking a batch of material through at least one stage in a process (32) in an installation for production of raw or semi-processed material using a process control system (20). Measurement data of physical parameters is recorded for each batch of material. On receipt of a user input via a workstation of the process control system (20) making a selection of one production stage (S10) for one batch of a plurality of batches, the measurement data is then filtered to extract measurement data for the one batch at the one selected stage and for at least one stage (C1, C2, C5; S1-S9, S11-S24; A1-A12, An-1-An-6) prior to the selected stage (S10, S27). The data for the selected batch and data for all prior stages leading up to it is displayed using a visualisation (8, 8') on a graphic user interface of the workstation (18, 19) of the process control system.</p> |
