conversion scale

The first sensitivity analysis considers changes only in the conversion scale of the qualitative criteria sustainability, with all other inputs maintained as used to obtain the third numerical example above (i.e., the defuzzified scores in the fourth column of Table 9).

The second sensitivity analysis is applied to changes only in the conversion scale of the qualitative score corporate governance.

The initial step requires defining conversion scales for the three qualitative criteria presented in Table 1.

At this point, we must remember that whenever using MCDA, it is important to fully understand how changes in the input parameters impact the scores (and the orderings) obtained, with special attention towards the conversion scales adopted.

In this sensitivity analysis, we consider that the conversion scales are exactly as exhibited in Table 3, Table 4 and Table 5, and that the level on uncertainty in the elements of the fuzzy decision matrix is kept fixed at 20% (i.e., [beta] = 20%).
