Logical Decisions - Classweb

Assume that you prefer A and B equally. This means that the
decrease in Power for B compared with A is just compensated for
by the increase in Fuel Economy.
This implies that the Power and Fuel Economy measures should
have equal weights given their ranges in this example. Assume
that you feel A and B are equally preferred. To let LDW know,
1. Click on the "Equal" button at the right of the window.
2. LDW will connect A and B with a line of equally
preferred possibilities and ask you of the proposed
tradeoff is OK.
3. Click “OK” to accept the tradeoff.
This returns you to the tradeoff dialog box. You will see the
tradeoff you just did listed in the "Previous Tradeoffs" box. You
will also see that you don't need any new tradeoffs for the
"Performance" goal.
Click the "Done" button to return to the assess weights dialog box.
We are done with the weight assessments for the "Performance"
goal.
Now we will do the assessments for the “Buy The Best Truck”
goal:
1. Select the "Buy the Best Truck" goal from the goals list.
2. Click on the "Assess" button to begin the assessment for
the "Best Truck" goal.
3. LDW will again display the tradeoff assessment dialog
box, but with a new list of measures and goals to select
from.
The list should now contain the "Performance" goal, the "Styling"
measure and the "Price" measure. The "Power" and "Fuel
Economy" measures don't appear on the list because they are in
the "Performance" goal. The list only contains the measures and
goals that are members of the "Buy the Best Truck" goal.
First, we will assess a tradeoff between Performance and Price.
