The US Cotton Ginning Laboratory (USCGL) in Stoneville, Mississippi has developed over the last 15 years the models, processes, and systems that have come to be known as Computerized Gin Process Control (CGPC or GPC). Stanley Anthony and his colleagues have reported on the concept and method at past Beltwide Cotton Conferences (Anthony, et al 1995; Byler and Anthony, 1995) and in other venues.
