Here we look at how to make sure the measurement system is able to provide the analysis, metrics, and control needed for process control improvement. Also outlined is the opportunity sizing and assessment process, the use of statistical tools, the tracking down of the source of variability, and the finding...

The benefits from process control improvement originate from increases in process efficiency, flexibility, and capacity. Often, there is a tradeoff where an increase in flexibility or capacity is accompanied by a decrease in efficiency. Better measurements, process knowledge, online metrics, and an enhanced PID can provide a more intelligent and effective...

According to Webster control is “to exercise restraining or directing influence over” whereas manage is “to exercise executive, administrative, and supervisory direction of”. Subtle but distinctly different. While process control may be necessary to ensure safety and proper operation it is process management that makes money for t

What is the most effective type of simulation? What is the fidelity needed? How can you automatically increase fidelity? How can you help operators deal with abnormal situations? How can you have a laboratory that behaves like the real plant to learn how the process responds, demonstrate creative control solutions, and quantify the benefits?
