Logical Decisions - Classweb

method uses a geometric approach to find a
reasonable set of weights based on your ordering.
! The "Smart" method lets you define the relative
importances of the active members using "swing
weights."
! The "Pairwise Weight Ratios" method is like the "Smart"
method except that you enter the relative
importances of pairs of active members directly.
! The "Analytic Hierarchy Process (AHP)" is an extension
of the "Pairwise Weight Ratios" method. Instead of
entering ratios for selected pairs of members, you
enter ratios for ALL possible pairs.
! The "Tradeoff" method defines weights by having you
compare simple alternatives that differ in two
active members but that you prefer equally. LDW
computes the weights that give these equally
preferred pairs equal utilities for the active goal.
! Finally, LDW lets you directly enter the weights for the
active members.
Each of these methods is discussed in detail in the following
sections.
You begin the weight assessment process by clicking the "Assess"
button. What happens next depends on the method you have
selected.
You can restore the active goal's MUF to its initial default state by
clicking the "Reset" button.
The status line above the weight assessment method tells you
how much of the assessment for the active goal you have
completed. A status of "Defaults Used" shows that you haven't
done any assessments for the active goal or that you have
initialized its MUF. "Partial Assessment" shows that you have
completed part of the weight assessment but not all. Finally,
"Assessment Complete" shows that you have completed all of the
needed assessments for the selected method.
You can review or make changes by clicking the "Assess" button
even if the status says "Assessment Complete".
