Efficient optimization of multiple objectives such as process time, viable cell density, number of operating steps & cultivation scales, required medium, amount of product as well as product quality depicts a promising approach. This contribution presents a workflow which couples uncertainty-based upstream simulation and Bayes optimization using Gaussian processes. Its application is demonstrated in a simulation case study for a relevant industrial task in process development, the design of a robust cell culture expansion process (seed train), meaning that despite uncertainties and variabilities concerning cell growth, low variations of viable cell density during the seed train are obtained. Compared to a non-optimized reference seed train, the optimized process showed much lower deviation rates regarding viable cell densities (<10% instead of 41.7%) using five or four shake flask scales and seed train duration could be reduced by 56 h from 576 h to 520 h. Overall, it is shown that applying Bayes optimization allows for optimization of a multi-objective optimization function with several optimizable input variables and under a considerable amount of constraints with a low computational effort. This approach provides the potential to be used in the form of a decision tool, e.g., for the choice of an optimal and robust seed train design or for further optimization tasks within process development."}],"publication":"Bioprocess Systems Engineering Applications in Pharmaceutical Manufacturing","publication_identifier":{"eissn":["2227-9717"],"isbn":["978-3-0365-5210-1"],"eisbn":["978-3-0365-5209-5"]},"author":[{"last_name":"Hernández Rodriguez","first_name":"Tanja","id":"52466","full_name":"Hernández Rodriguez, Tanja"},{"full_name":"Sekulic, Anton","first_name":"Anton","last_name":"Sekulic"},{"full_name":"Lange-Hegermann, Markus","id":"71761","first_name":"Markus","last_name":"Lange-Hegermann"},{"last_name":"Frahm","first_name":"Björn","id":"45666","full_name":"Frahm, Björn"}],"publisher":"MDPI","page":"21-48","doi":"https://doi.org/10.3390/pr10050883","department":[{"_id":"DEP4000"}],"user_id":"83781"}
