Logical Decisions - Classweb

The utility of an alternative on the "Overall" goal is its overall
utility. The alternative with the highest overall utility is the most
preferred.
Deciding which Goals Should Have a MUF
LDW includes each measure in your analysis in the MUF for
exactly one goal. In addition, LDW includes goals that have their
own MUF in the MUF for exactly one higher level goal. LDW
does not explicitly include goals that do not have their own MUF
in any other MUF.
LDW lets you decide which goals should have their own MUF. A
goal that has its own MUF will combine the utilities for the
measures and goals directly below it in the goals hierarchy into a
utility for the goal.
The exception is that the MUF for a goal will not include the
utility for a goal directly below it that does not have its own MUF.
Call the goal having the MUF the MUF-Goal and the goal below it
without a MUF the NONMUF-Goal. LDW includes the utilities
for each of the NONMUF-Goal's members in the MUF-Goal's
MUF.
If you request a ranking of the alternatives on the NONMUF-Goal
LDW will compute a temporary MUF for it. The MUF will
combine the utilities of the goal's members based on their weights
in the MUF-Goal MUF. The only goal required to have its own
MUF is the "Overall" goal.
Figure 9-7 shows how you might combine the members and goals
in a goals hierarchy into MUFs.
