Logical Decisions - Classweb

Initial Steps
Before you can begin the analysis you need to install the program
and start it. See page 2-1 for how to install LDW. To start LDW,
just double-click its icon in the Logical Decisions program group.
If you have opened one of the example files, you should select the
File::New option to begin a new analysis.
Defining Alternatives
The first step in your decision analysis is to define the alternatives
to be ranked. You will rank the following (hypothetical) small
pickup trucks:
! Coyote
! Mountain Lion
! Wolf
The alternatives are new pickup trucks with roughly the same
levels of accessories.
We will define the alternatives in the Matrix view. LDW displays
the Matrix view when you first start it. It is the window with the
spreadsheet table of measures and alternatives.
If you have closed the Matrix view, you can get a new one by
selecting the View::Matrix option. Initially, there is just one
alternative -- "New Alternative" -- and one evaluation measure --
"New Measure" – in the spreadsheet.
We can quickly add the alternatives in the matrix view. Here’s
how:
1. Double Click the cell labeled “New Alternative” in the
Matrix. This will open its properties dialog box.
2. Type the name “Coyote” into the name edit.
3. Click the “Add Another Alternative” button to add a
new alternative and open its properties dialog box.
4. Type the name “Mountain Lion
5. Click “Add Another Alternative” again and call it
“Wolf”
