Adding a Preference Set. You can add a new preference set to
your analysis using the Edit::Add option. Just select the
"Preference Set" radio button and click OK. LDW will give you
the option of copying an existing preference set or adding a new
default preference set. If you copy an existing preference set,
LDW also copies all of the preference information associated with
the preference set. LDW assigns new preference sets the defaults
for all needed preference information. You can also add a new
preference by selecting the View::Select/Change Preference
Sets option as described above.
Deleting a Preference Set. You can delete a preference set using
the Edit::Delete option. Just select the "Preference Set" radio
button and click OK. LDW will ask you to select a preference set
from a list and then to confirm before it deletes the preference set.
You can also delete a preference set by selecting the
View::Select/Change Preference Sets option as described above.
If you just want to initialize all or part of your preference
information to the default values, don't delete the preference set.
Instead, use the initialization options in the preference set
properties dialog box discussed in the next section.
Modifying a Preference Set. You can change the name and other
information about a preference set by using its preference set
dialog box. You can view the preference set dialog box by double
clicking on the name of a preference set in the View::Summary
option's dialog box or by clicking the “Properties” button in the
View::Select/Change Preference Sets option.
In the preference set dialog box, the "Name" edit box in the upper
left corner defines how LDW describes the preference set. The
"ID Number" field allows an alternate description or code for the
measure. You can use the Preferences::Change Names option to
control how LDW uses these two fields to describe each
preference set. The comments field at the bottom of the dialog
box lets you provide a more detailed description of your
preference set.
Under the “Structure” tab in the preference set dialog box, the
"Goals with a MUF" list box identifies which of the goals in the
analysis will have their own utility function. You can select a
goal to have a utility function by clicking on an un-highlighted
goal. You can delete the utility function for a goal by clicking on
its name to un-highlight it. LDW saves as much preference
