Multi-objective optimal control of chemical processes using ACADO toolkit

Many practical chemical engineering problems involve the determination of optimal trajectories given multiple and conflicting objectives. These conflicting objectives typically give rise to a set of Pareto optimal solutions. To enhance real-time decision making efficient approaches are required for determining the Pareto set in a fast and accurate way. Hereto, the current paper illustrates the use of the freely available toolkit ACADO Multi-Objective (www.acadotoolkit.org) on several chemical examples. The rationale behind ACADO Multi-Objective is the integration of direct optimal control methods with scalarisation-based multi-objective methods enabling the exploitation of fast deterministic gradient-based optimisation routines.

► Fast & accurate generation of Pareto sets for dynamic chemical processes.
► Implementation in open source toolkit called ACADO Multi-Objective.
► Combine direct optimal control methods (single & multiple shooting) & scalarisation multi-objective methods (NBI, NNC & ENNC).
