Computational toolkits for model-based design and optimization

We review recent advances in software platforms for modelbased design (MBD) organized in five overarching themes - from (1) simulation to optimization, (2) commercial to opensource, (3) process-centric to multiscale, (4) mechanistic to data-driven, and (5) deterministic to uncertain - illustrated with several recent examples in membrane system design. We posit MBD provides (chemical) engineers with principled frameworks to tackle global grand challenges such as sustainable energy, clean water, and equitable access to healthcare by integrating knowledge across disciplines. As such, we predict MBD software, which has historically focused on engineered systems, will evolve to interact with models for natural and social systems more holistically. Finally, we emphasize the importance of open-source software development, especially by users who become contributors.
