Structuring Goals The goals in an LDW analysis are the concerns or objectives that are affected by selecting an alternative. You describe the goals in terms of the measures and sub-goals that are their members, but you also must name each goal. You can also add comments and an ID number. You define a goal's members in the Goals Hierarchy or Quick Entry view. The members of a goal are those measures and other goals that are directly under the goal in the hierarchy. You can use the options in the Edit menu to add, delete or modify the members of a goal. Each measure and goal is a member of exactly one goal, except the "Overall" goal, which defines the top of the goals hierarchy. You can view or modify the other information about a goal in its goal properties dialog box. You can view a goal's properties box by double clicking on its box in the Goals Hierarchy or Quick Entry view, double clicking its line in the Summary dialog box, or with the Edit::Modify option. In the dialog box, the "Name" field defines how LDW refers to the goal in various lists and tables. The "ID Number" field allows an alternate description or code for the goal. You can use the Option::Change Names option to control how LDW uses these two fields to describe each goal. The comments field at the bottom of the dialog box lets you provide a more detailed description of your goal. LDW needs the "Nominal Utility" field when using representatives for the goal in assessing weights. It is the utility that LDW assigns to the other members (besides the representative) when computing the goal's weight from the weight of the representative. You should leave the nominal utility at one unless you are a very advanced LDW user. The options under the “Position” tab control where the goal is located in the goals hierarchy. The "Goal Under" combo box identifies the goal directly above the active goal in the goals hierarchy. You can change the selection in this box to move the active goal beneath any other goal in the hierarchy. If you do this, LDW also moves all of the members of the selected goal. LDW asks you to confirm this change when you close the dialog box. 6-16 Section 6 -- Using LDW 1: Structuring
The "Members" list is a list of all the measures and goals in the analysis. The measures and goals highlighted in the list are the members of the selected goal. You can add a member to the goal by clicking on an un-highlighted measure or goal to make it a member. You can delete a member from the goal by clicking on it to unhighlight it. LDW asks you to confirm all changes in the goal's member list when you close the dialog box. Some changes create loops in the hierarchy and aren't allowed. Adding a Goal. You can add a goal at any time using the Edit::Add option. Just select the "Goal" button and click OK. You can also use the Add a Goal option in the Goals Hierarchy or Quick Entry view. To do this you must first select an existing goal or measure to tell LDW where to add the new goal. If you have previously saved a goal using the Edit::Cut or Edit::Copy option you can retrieve it with the Edit::Paste option. New goals are added below the active goal or below the goal the active measure belongs to in the hierarchy. Deleting a Goal. You can delete a goal at any time using the Edit::Delete option. The deleted goal's members will become members of the next higher goal in the hierarchy. You can also delete a goal by clicking on it and then selecting the Edit::Cut option. The Cut option saves a copy of the goal and its members for later pasting. Structuring Evaluation Measures The measures in an LDW analysis are the variables that describe an alternative and are also the lowest level objectives of the analysis. You describe the alternatives in terms of their levels on the measures. You define a measure in terms of its scale, units and range, but you also must name each measure. You can also add comments and an ID number if you want. You can view or modify the information about a measure in its properties dialog box. You can view a measure's properties dialog box by double clicking on its box in the Goals Hierarchy view, Matrix view, or Quick Edit view, double clicking its line in the Summary dialog box, or with the Edit::Modify option. In the dialog box, the "Name" field defines how LDW describes the measure in various lists and tables. The "ID Number" field allows an alternate description or code for the measure. You can use the Option::Change Names option to control how LDW uses Section 6 -- Using LDW 1: Structuring 6-17

Structuring Goals<br />
The goals in an LDW analysis are the concerns or objectives that<br />
are affected by selecting an alternative. You describe the goals in<br />
terms of the measures and sub-goals that are their members, but<br />
you also must name each goal. You can also add comments and<br />
an ID number.<br />
You define a goal's members in the Goals Hierarchy or Quick<br />
Entry view. The members of a goal are those measures and other<br />
goals that are directly under the goal in the hierarchy. You can<br />
use the options in the Edit menu to add, delete or modify the<br />
members of a goal. Each measure and goal is a member of exactly<br />
one goal, except the "Overall" goal, which defines the top of the<br />
goals hierarchy.<br />
You can view or modify the other information about a goal in its<br />
goal properties dialog box. You can view a goal's properties box<br />
by double clicking on its box in the Goals Hierarchy or Quick<br />
Entry view, double clicking its line in the Summary dialog box, or<br />
with the Edit::Modify option.<br />
In the dialog box, the "Name" field defines how LDW refers to the<br />
goal in various lists and tables. The "ID Number" field allows an<br />
alternate description or code for the goal. You can use the<br />
Option::Change Names option to control how LDW uses these<br />
two fields to describe each goal. The comments field at the<br />
bottom of the dialog box lets you provide a more detailed<br />
description of your goal.<br />
LDW needs the "Nominal Utility" field when using<br />
representatives for the goal in assessing weights. It is the utility<br />
that LDW assigns to the other members (besides the<br />
representative) when computing the goal's weight from the<br />
weight of the representative. You should leave the nominal<br />
utility at one unless you are a very advanced LDW user.<br />
The options under the “Position” tab control where the goal is<br />
located in the goals hierarchy. The "Goal Under" combo box<br />
identifies the goal directly above the active goal in the goals<br />
hierarchy. You can change the selection in this box to move the<br />
active goal beneath any other goal in the hierarchy. If you do this,<br />
LDW also moves all of the members of the selected goal. LDW<br />
asks you to confirm this change when you close the dialog box.<br />
