Multiobjective Optimization for Plastic Sheet Production

In this work, we formulate a Multiobjective Optimization problem using conflicting performance objectives in polymerization systems such as maximize monomer conversion and minimize molecular weight distribution. The problem is subject to a mathematical model comprising highly nonlinear Partial Differential Equations. These describe the dynamic response of the poly( methyl methacrylate) cell-cast process. A full discretization approach was used for solving the associated Nonlinear Programming problems. We analyze the effect of different process constraints on the Pareto curve and select suitable operating policies in an open-loop environment.
