Process Analysis

Regressive process models and their transparent, dynamic visualisation form the basis for discussions with our process experts. The potential for optimisation they identify then serves as a process roadmap for the subsequent APCTools:


With the band width controller it is possible to use buffer facilities and ensure uniform output to the subsequent process. This filters out any fluctuations and interference from previous processes, so resulting in stable process conditions.


The soft sensor uses the input quality and process settings to calculate the target quality and displays this online. A particular advantage when it comes to measured values which cannot be determined at once, involving time-consuming analysis at the laboratory, or when monitoring critical variables or as a substitute for missing online measurements in the event of breakdown.

eMPC – enhanced Model Predictive Control

eMPC acts like a GPS system, using process models as a roadmap, controlling the target values under the current raw material and process conditions. Flexible weighting is used for the strategy. Operation of the controller is predictive, continuously adapting to the latest target values measured.

ePO – enhanced Process Optimizer

Whether in an individual process stage or a lengthy production process, the ePO will monitor the relationship between process settings and production costs. It is responsible for coordinating the production specifications for each process stage and calculating the most cost-efficient strategy for the required product qualities and production volumes.
