EPC is a combination of SPC and feedback control often referred to as
algorithmic process control. It frequently is employed using PID
controllers and computer driven SPC in those industies with continuous as
well as discrete processes. For an introduction please see "Real Time
Process Quality Control..." by Yourstone in Statistical Process Control
in Manufacturing, Keats and Montgomery, ed., 1991 ISBN 0-8247-8467-7.

I would be very grateful to be invited to the interment of PreControl
Charts. The recent article in JQT should have put the last nail in the
coffin of this bit of pseudostatistical chicanery.
