9. LDW will ask if you want to append new alternatives
whose names match existing alternatives.
10. We don't want to do this, so answer "No."
11. LDW will ask if you want to "Apply Cutoffs". If you
answer yes, LDW will not append an alternative that
fails any of the cutoffs.
12. We don't want to append failing alternatives, so answer
"Yes."
13. LDW will ask you to enter the maximum number to
append. If you enter a number less than the number of
records in the file (say 10), LDW will rank each
alternative as it reads it and will only append the top 10
ranking alternatives.
14. For now, just accept the default large number by
clicking “OK.”
When you click "OK", LDW will scan the database and append
any records that pass all the cutoffs.
If you next look at the Matrix view, you will see that only one new
alternative has been appended -- the "Tiger". The "Coyote",
"Mountain Lion" and "Wolf" records were not appended because
their names matched existing alternatives.
The "Falcon" alternative was not appended because its price of
$27,000 was above the upper cutoff of $25,000. The "Crocodile"
alternative was not appended because its styling label --
"Laughable" -- was not on the list of acceptable labels.
Defining Interactions Between Goal Members
The final (optional) step in the preference assessment process is to
define the interactions between the members of the goals. This is
probably the most unfamiliar part of the process and the most
difficult to explain. Fortunately, in most situations interactions
are not needed and the default weighted average is the
appropriate way to combine an alternatives utilities on the
measures. See page 9-55.
