3. Assessment of the conditional utility functions.
4. Assessment of the scaling constants.
5. Consistency check.
Before the assessment began it was made very clear to the DM that the
preferences of interest to the model are his. It was explained that there are no correct
preferences and that the preferences should represent his subject feelings.
Also, since one of the purposes of the utility analysis is to make the DM think
with care about his preferences, it was emphasized that changes along the process were
completely normal and necessary for a correct analysis.
As described earlier, the ranges of the attributes were defined based on research
and expert assessment. Thus, it was also emphasized that the preferences assessed should
only consider the consequences within that limited space, which is represented by (y, z)
with y 0 ≤y≤y * and z 0 ≤z≤z * (see fig. 26). 106
