Logical Decisions - Classweb

Now lets make sure the alternatives are in alphabetical order.
Click on the (Preferences::Sort) option and select the "Name"
and "Ascending" radio buttons under both "Sort Rows" and "Sort
Columns." The alternative rows should be in the order Coyote,
Mountain Lion, Wolf. The columns for the measures will also be
sorted alphabetically.
This completes the preliminary definition of the alternatives. We
will describe them in detail by entering their levels (raw scores)
after we have defined the measures.
Defining Goals -- How You Will Compare the
Trucks
Goals let you define the concerns important to you when selecting
a truck to buy. You will organize those concerns in a goals
hierarchy with general concerns at the top and more specific
concerns toward the bottom. Goals hierarchies are discussed more
on page 9-6. In LDW, goals are collections of measures and other
(lower level) goals.
Let's assume you have very simple requirements. Your overall
goal is to Select the Best Truck, and you will do this by comparing
price, performance, and styling. So, under the overall goal you
have the sub-goals:
! Minimize Cost
! Maximize Performance
! Maximize Styling Quality
To represent this hierarchy, you can define four goals --
! Overall
! Cost
! Performance
! Styling
LDW predefines the Overall goal -- selecting the best truck -- so
you do not need to add it explicitly.
The cost and styling goals will only have one measure each (price
and styling) so you don't need to define separate goals for them.
(Goals should generally have at least two members).
