Tuning a process while performing SPC: an approach based on the sequential design of experiments

An approach to process control called generalized SPC which allows for the diagnosis of a process while the process is being tuned is discussed. A control module, the run by run controller, that implements a form of adaptive control based on the sequential design of experiments is discussed. Statistical process control is compared to the run by run controller.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
