1. A system comprising: a parametric multifaceted model of a plurality of process plants configured to receive inputs from the process plants, and to map between a first set of parameters relating to a first facet of the parametric multifaceted model of the process plants and a second set of parameters relating to a second facet of the parametric multifaceted model of the process plants; an optimization system configured to optimize integrated operation of the process plants using the second set of parameters and a first parameterized input/output control model, wherein the first parameterized input/output control model comprises a short-cut model; and a control system configured to control integrated operation of the process plants using the first set of parameters and a second parameterized input/output control model, wherein the second parameterized input/output control model comprises a detailed dynamic model, wherein the first set of parameters is different than the second set of parameters and mapping between the first set of parameters and the second set of parameters facilitates maintaining consistency between the first parameterized input/output control model and the second parameterized input/output control model, wherein the mapping between the first set of parameters and the second set of parameters is a function of current and/or anticipated operating conditions of the process plants and occurs over a time horizon during operation of the process plants to facilitate control of the process plants; and wherein the parametric multifaceted model comprises a parametric non-linear dynamic approximator and a dynamic parameterized model coupled in series.
