“…Then, partial realistic preferences for the feature interaction directions are considered, and these constraints are added to the optimization model. And the maximum separation model is constructed as (19). LINGO 18.0 software is used to solve the model to obtain optimal feature capacities as ψ(C j ) = {s −2 (0.004), s −1 (0.009), s 0 (0.019), s 1 (0.182), s 2 (0.786)} {s −2 (0.048), s −1 (0.044), s 0 (0.018), s 1 (0.246), s 2 (0.643)} A 10 {s −2 (0.011), s −1 (0.015), s 0 (0.013), s 1 (0.146), s 2 (0.815)} {s −2 (0.039), s −1 (0.042), s 0 (0.015), s 1 (0.166), s 2 (0.738)} A 11 {s −2 (0.007), s −1 (0.024), s 0 (0.05), s 1 (0.264), s 2 (0.655)} {s −2 (0.059), s −1 (0.086), s 0 (0.035), s 1 (0.217), s 2 (0.604)} A 12 {s −2 (0.013), s −1 (0.011), s 0 (0.018), s 1 (0.17), s 2 (0.787)} {s −2 (0.081), s −1 (0.071), s 0 (0.024), s 1 (0.197), s 2 (0.629)} A 13 {s −2 (0.008), s −1 (0.012), s 0 (0.019), s 1 (0.112), s 2 (0.849)} {s −2 (0.04), s −1 (0.032), s 0 (0.018), s 1 (0.13), s 2 (0.78)} A 14 {s −2 (0.006), s −1 (0.017), s 0 (0.029), s 1 (0.154), s 2 (0.794)} {s −2 (0.098), s −1 (0.275), s 0 (0), s 1 (0.137), s 2 (0.49)} A 15 {s −2 (0.014), s −1 (0.025), s 0 (0.021), s 1 (0.…”
