The idea of the Import Structure option is that you will use it in
combination with the Append option in a two pass approach. In
the first pass you would select the Import Structure option to
identify the measures and their ranges. Then you would massage
that information in LDW, eliminating irrelevant measures,
identifying measures where lower levels are preferred, modifying
measure ranges, setting cutoffs, etc. At this time, you could also
organize the measures into a goals hierarchy and do preference
assessments.
Next you would use the Append option to load in the
alternatives. You can apply the ranking and cutoffs filters
available there to load in only those alternatives that are most
promising and that pass all the cutoffs.
If you selected the Update option, LDW will use the data in the
import file to selectively update the alternatives in your analysis.
After you have selected the name of the import file, LDW asks
you to select the measures in your analysis it should update and
the fields from the import file that it should use as the source of
the updates. You do this using the dialog box in Figure 8-58.

select a measure for updating, click its name in the left list and
