Talk:Advanced process control

A broad term
Advanced process control (APC) is a broad term of which multivariable control is a subset. You can have APC controllers that are not multivariable. -- Bala


 * You are right, APC is a much broader term (than for just petrochemical industries). Multivariable control is mostly included in APC, but not always. I update the page. Cjohnzen 14:22, 21 March 2006 (UTC)

OpenAPC is not "Open Source" software
From what I can gather from the license presented on the web site for this company (www.openapc.com), the software they sell is not open source in any sense. It seems to be a close-source commercial product. I revised the link to point to the Open APC Foundation instead. Rbh1976 (talk) 19:24, 5 April 2011 (UTC)
