Advanced Process Control Increases Profits
Advanced process control has come to be a term synonymous with
computer based technologies. Many companies use this process to
help them with increasing their profits by improving the product
capacity and minimizing expenses. Some companies have reported
that they have cut their operating expenses by up to 6% once
they started using advanced process control.
The exact meaning of advanced process control depends on what a
company uses it for. It could mean cascade control features, a
time delay compensator or optimization strategies. In layman's
terms it refers to using computer software to make things work
smoothly and efficiently. Modern approaches to this system rely
upon a study of system behavior and using process models.
Models of advanced process control
There are four models in advanced process control: 1.
Mechanistic model - the structure of the final model that is
desired can be either a lumped parameter or a distributed
parameter. A lumped parameter uses ordinary differential
equations while a differential parameter is used to describe
behavior in one dimension and is much more complex. The
mechanistic model of advanced process control is not financially
feasible for most companies.
2. Black Box Model - this model describes the relationship
between the system inputs and outputs. It can track trends in
process behavior.
3. Qualitative model - this model is used when the process needs
mathematical configuration or when the process is carried out at
distinct operating systems.
4. Statistical model - this model describes techniques in terms
of statistics. It provides information about the likelihood of
something happening so that a solution can be found before a
problem occurs. This model does not capture system dynamics. It
does play an important role in analysing data so as to assist in
higher level decision making.
Using one or more of these models helps companies to see where
they can cut down on their expenditures and increase their
profit margins.
