[edit] 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)
