Optimal experiment design Technologies gPROMS ...

Example: Fed-batch fermentation experiments. The purpose of the simple fed-batch fermentation process shown here is to estimate the unknown parameters θ i = 1..4, as accurately as possible with the minimum number of experiments. A simple design (constant feed and equidistant measurements) will give very weak estimates of the parameters.

Tutorial 4: gPROMS Configuration — FOQUS

2021-7-15  Unlike Aspen, changes have to be made to the gPROMS simulation process in order to work with SimSinter. In fact, SimSinter does not define the inputs to the simulation, gPROMS does. On the other hand, gPROMS does not determine the outputs, SimSinter does. This odd and counter-intuitive situation is the result of how gPROMS gO:Run_XML is designed.
