Robust Optimization
The same membrane diafiltration case study was also used
to demonstrate PrOMMiS capabilities for technical risk
reduction via robust optimization. Industrial processes
must be able to perform satisfactorily in light of pro-
cess and thermophysical uncertainties. In the membrane
diafiltration cascade application, there exists potential
uncertainty over the location and rate of membrane foul-
ing, feedstock concentration and flowrate, and membrane
manufacturing variation. Understanding the potential
impacts of these phenomena on process performance and
understanding how to minimize those impacts via process
