Optimisation: DoE and RS Methods
Design of Experiment and Response Surface Methods are techniques which sample the objective function and construct an approximation to it - this is very effective where each of the performance simulations is expensive and might require hours of computer time and can dramatically speed up your search for a better design. This so-called "surrogate" surface is then searched using the previous methods and then further refined using additional performance simulations. At the end of the optimisation the improved designs proposed to you are always simulated using the performance simulation you have set up and these results are available to work on further as part of your design process.
