In 2016, we introduced the concept of model‐predictive safety (MPS; Ahooyi et al,AIChE J. 2016; 62:2024‐2042). MPS is a proposed innovation in functional safety systems to methodically account for process nonlinearities and variable interactions to enable predictive, prescriptive actions, while existing functional safety systems generally react when individual process variables exceed thresholds. MPS systematically utilizes a dynamic process model to detect imminent and potential future operation hazards in real time and to take optimal preventive and mitigative actions proactively. This work expands the concept of MPS and formulates two min–max optimization problems, offline solutions of which are the optimal proactive preventive and mitigating actions that MPS takes online, in response to predicted process operation hazards. A nested particle‐swarm optimization (PSO) algorithm is proposed to solve the min–max optimization problems. The application and performance of the min–max optimization formulations, the PSO algorithm, and MPS, applied to two chemical process examples, are shown through numerical simulations.
