Economic MPC

Economic MPC (EMPC) is an advanced control strategy that integrates economic objectives directly into the model predictive control framework, rather than just minimizing tracking error. This single-layer approach resolves the conflict between RTO and MPC layers found in traditional control architectures. According to ISO 22301 and ISO 27701, it ensures critical business functions remain economically viable during disruptions. Unlike conventional MPC, which only pursues stability, EMPC optimizes for economic performance in real-time, making it a key tool for both operational efficiency and risk-adjusted resilience. This approach is particularly relevant for industries facing volatile energy prices or carbon-related regulations, where economic stability is a prerequisite for business continuity.

Implementation typically follows three steps: 1) System identification and economic model formulation; 2) Gradient-based controller design and constraint integration; 3) Field validation and risk-adjusted-tuning. For example, a Taiwanese petrochemical plant can use EMPC to dynamically adjust the propylene/propane splitter's-operating point in response to real-time energy prices, ensuring the highest economic yield while adhering to environmental regulations. This directly impacts the RTO (Recovery Time Objective) and RPO (Recovery Point Objective) metrics by minimizing economic losses during disturbances. Companies using EMPC have reported up to a 20% reduction in energy-related costs and a 15% improvement in stability-adjusted profit-per-unit-produced compared to traditional control methods.

Three main challenges exist: Technical Talent Gap, Data Silos, and Risk-Adjusted ROI Justification. First, the talent shortage can be addressed through partnerships with universities or specialized consultants like Winners Consulting. Second, data silos between OT and IT systems can be resolved by implementing unified data-sharing platforms (compliant with ISO 27701). Third, the difficulty in quantifying the ROI of a control-level upgrade often leads to project delays; this can be mitigated by framing EMPC as a component of the ISO 22301 Business Continuity Management System (BCMS), where economic resilience is a measurable outcome. The priority should be a 3-month pilot project to demonstrate value before full-scale deployment.
