G. G. Bordonaro et alii, Frattura ed Integrità Strutturale, 44 (2018) 1-15; DOI: 10.3221/IGF-ESIS.44.01 13 Acceptability limits and target values are defined for each response. Table 3 shows the acceptability value and the target value for each response. Response Acceptability Target Spread Y 1 [mm] ≥ 26 27 Contacts stress Y 2 [MPa] 130 200 Non-Contact stress Y 3 [MPa] 200 130 Rolls force Y 4 [kN] ≤ 125 80 Table 3 : Acceptability value and target value for each response. 317 points are non-dominated, but none of them satisfies simultaneously the acceptability requirements for all responses. Figure 14 shows the predicted values for the responses Y 1 and Y 4 . Figure 14 : Spread vs. force (predicted values). Figure 15 : Simulated results for the selected conditions.
