An overview is presented on existing multi-objective, one-layer and two-layer architectures that incorporate dynamic real-time optimisation for optimal process performance. A one-layer architecture, that entails a Non-linear Model Predictive Control formulation, is consequently proposed that attempts to address shortcomings identified with one-layer approaches. The proposed architecture is applied to a simplified non-linear, multi-well oil production case study, which illustrates the benefits of such an approach. |
