Design of experiment

Assuming that the responses of the experiment can be approximated well with a linear model, we opted for a fractional factorial. For the first round of measurements, we chose to design the experiment such as to minimise the costs. As we have five factors, we used a 25-3 design [\ref{874005}] with the generator (1, 2, 3, 13, 23), yielding 8 measurement runs to perform. The system is of resolution III, meaning that the main effects are aliased with first order interactions.
