APC modules

Our tools create a digital twin of your facilities. High end automationX eMPC is used for completed process steps and automationX ePO for plant-wide process and production optimization.


Model Predictive Control

eModelPredictiveControl solutions optimize specific stages in a process. We use the classic advanced process control approach. Optimization of individual steps in the process that takes into account all conditions such as quality and production permits a great amount of savings (additives, raw materials, etc.) and a maximization of the required quality.

  • Reduced variances
  • Optimal set points
  • Maximum process stability
  • Minimized operator interventions
  • Reduced use of raw materials
  • Minimized rejects
  • Best possible quality
  • Adaptive model correction
  • Robust process models (24/7)
  • Soft sensors (replacement for or plausibility monitoring of physical measurements)


Process Optimizer

The eProcessOptimizer enables completely interconnected process optimization throughout all the process steps. In contrast to Standard systems, hybrid physical and historical models that are interconnected with all the required systems (ERP, PLS, QCS, etc.) combine time and energy optimization (Balanced Manufacturing―BaMa). aXBaMa Toolchain makes simulation and optimization of the entire plant possible. Our tools are based on hybrid discrete event system mechanisms (hybrid DEVS) with which you can link together a great number of different models in order to describe your plants.

  • Production coordination—optimized production sequence
  • Energy efficient production (cost optimization)
  • Preparation of process and storage for unplanned events (optimal time for your maintenance))
  • Comparison of scenarios to support production decisions
  • Real-time variance analysis
  • Quality and material tracking
  • Balancing of the most important process flows
  • Simulation and optimization of the entire plant using empirical and/or physical models
  • Identification of production limits (bottlenecks)
  • Interfaces to ERP, DCS, PLC and QCS systems
  • Automated and personalized reports



The way to optimal performance


Group level data acquisition with standardized ioT mechanisms—made possible by interfaces to all required process levels (horizontal and vertical). Separate validation processes allow safe processing of collected process data.


We analyze your processes and find relationships between parameters related to production and quality. Based on these findings, we create mathematical models that are empirical and/or physical. Missing measurements and laboratory analysis are provided by aX soft sensors.


Model predictive solutions enable the optimization of production and quality and the minimization of costs. Process modeling and simulation deepen understanding of the process. They recognize critical process steps and bottlenecks and can effectively counteract them.


Model-based simulation and optimization solutions employ a digital twin of your facility. This copy, which includes an online interface to the production process, supplies a variety of additional information—from basic OEE to optimized maintenance intervals.

Operator Training Simulator

Training simulators make up an entire area of production including utilities and secondary facilities. The visualization includes graphics, control blocks and features of the actual process (models). Simulators greatly increase the efficiency of employee training and professional development. Such an installation is built upon a variety of mathematical relationships based on physical and empirical models.


Balanced Manufacturing

The automationX BaMa tool provides a simulation-based method for monitoring, predicting and optimizing the energy and resources required by production companies that takes into account the economic success factors time, cost and quality. A digital twin of your facility is the basis for simulation and optimization!


Management of filler and rejects in paper machines

Our ePM solution enables all types of paper to be produced at the best cost and quick and precise changes between the paper grades being produced. Significant savings are achieved by maximizing the amount of filler introduced via the rejects or the fresh filler according to availability. Seamless alternating between quality and cost-effective modes of operation enables flexible adjustment to customer and product requirements.

The continual adjustment of fresh filler, amounts of rejects and chemical agents reduces the variance in the ash content of the base paper as well as variances in the retention system. This permits higher target values for ash in all grades of paper depending on what is physically possible. The innovative hybrid eMPC technology makes it possible to reproduce discrete process conditions and constant dynamic process behavior in a common process model and thus to critically improve control behavior.

Integrated management of rejects results in optimal control of rejects as well as a considerable easing of the burden on the operating team.

Project goals/accomplishments Increase in control accuracy of ash > 70%
Variance reduction in ash > 50%
Implementation period 6 months  
Amortization  < 6 months  



Stabilized pulp bleaching

The ePULP system monitors the effect of the bleaching agent minute by minute and continually adjusts the use of chemicals so that more stable process conditions (e.g., pH number) and a clearly lower variance in end quality are achieved. As a result, the operating team does not have to deal with any changes in the process and can concentrate exclusively on operations.

Avoiding excessive quality immediately results in the use of fewer chemicals. Since there is less variance, the set point and the average value of brightness finished pulp are reduced by several tenths of a percent and the total amount of bleaching agent is optimally distributed between all the steps. Not only does this ease the burden on the operating team, but also significant economic success is demonstrated and the environmental impact is reduced as a result of lower consumption of bleaching chemicals.

Project goals/accomplishments Reduced chemical use > 10%
Variance reduction in white finished stock > 35%
Implementation period 6 months  
Amortization < 8 months  



Increased refiner efficiency

eTMP ensures that a refiner is operated at the best cost. Process models of every refiner step ensure a local optimum is achieved. Missing online measurements of quality are provided by soft sensors. A higher level optimization module takes care of load shifting and thus targeted energy savings. As a result, much better exploitation of energy efficient components is possible. Computing cycles at one minute intervals permit continual adjustment of the required set points. In addition, the daily energy price forecast is taken into account during production. Intelligent optimization algorithms exploit tank levels skillfully to operate the refiners at the lowest energy costs.

Project goals/accomplishments

Savings in electrical energy > 5%
Variance reduction in quality (shives) > 25%

Implementation period 10 months  
Amortization < 6 months  



Maximized deinking yield

Implementation of an eDIP solution in the deinking plant provides the basis for a process management procedure that immediately reacts with appropriate measures to any fluctuations in raw materials and variations in the process, stabilizes quality, reduces costs and increases yield.

A higher level optimizer controls the individual steps (drum pulping, preflotation, postflotation, bleaching) as well as the process steps at all levels. This allows cost-effective DIP material preparation while meeting the defined quality goals for ash content and brightness.

Project goals/accomplishments

Maximized yield > 1%
Variance reduction in ash/whiteness > 35%
Reduced chemical use > 10%

Implementation period 8 months 
Amortization < 6 months 



Reduced drying energy

Around 70% of the total energy required by the paper industry is used for drying processes. This is reason enough to invest in reducing steam consumption. eDRY manages this without any need for intervention by your operating team. Hybrid process models (empirical and physical) that include all secondary processes reproduce the drying process, thereby enabling virtual representation of the actual paper machine. Closed loop operation of the actual paper machine optimizes steam consumption in the dryer group. The key to success is the calculated dry content after the press section.
Using the ePM solution, steam consumption is reduced considerably without exceeding the quality limits.

Project goals/accomplishments

Reduced steam consumption > 6%

Implementation period 10 months 
Amortization < 6 months
