R. Citarella et alii, Frattura ed Integrità Strutturale, 34 (2015) 554-563; DOI: 10.3221/IGF-ESIS.34.61 563 carry out four additional simulations, corresponding to the four combinations of noise levels defined in the numerical plan. The performance parameters corresponding to the optimal configuration will come out from an average of the results obtained from the four simulations. The confirmation experiment provided a positive assessment. C ONCLUSIONS he adopted values of the control factors are varying in a small range since this analysis is part of a refinement that starts from a prior knowledge of the phenomenon and allows an a priori restriction of the domain in which to search for the optimum. This also explains the use of only two levels for the control and noise factors. The DoE approach allows to analyse a limited number of design configurations of the coupling without penalising the information content available from e.g. an extensive plan of numerical simulations, provided that there are no interactions (as in this case) between the control factors that would invalidate the applicability of the superposition principle.
