Advanced Process Control (APC)
The Advanced Process Control (APC) is a collection of software that
helps in controlling critical variables and forecasting real-time quality.
This software includes the Statistical Process Control (SPC), which
makes use of statistical analysis and random sampling to determine
an external cause of why the quality of a product changed.
The Run2Run (R2R) is also included in the list. Although it is
commonly used in the semiconductor industry, it is also applicable to
batch processes in the likes of chemical vapor deposition and batch
chemical reactors. Using the R2R, the product quality is tested every
end of the run, consequently changing set-points between two
consecutive runs.
The APC has proven its competitiveness in the market, one such plant
having an increased rate of production of five percent and saving as
much as €1.3 million.
