Using LDW 1: Structuring
Introduction
The next three sections describe how to use Logical Decisions
(LDW) by providing detailed instructions on the three main steps
in an LDW analysis:
! Structuring the analysis,
! Assessing preferences, and
! Reviewing results.
This section describes the LDW options related to structuring the
analysis. The next sections describe options for assessing
preferences and reviewing results. You should read the Quick
Start section before these sections.
Structuring a Logical Decisions Analysis
You structure an LDW analysis by defining the alternatives you
will rank, the measures you will use to describe the alternatives,
and the goals you will use to group the measures. Its best to
finish structuring your analysis before you begin the preference
assessment step. However, since this is not always possible, LDW
lets you make structural changes any time with only a minimum
loss of preference data
.
This section includes descriptions of the editing options available
for structuring your analysis and of the views where the
structuring takes place. Then there is a discussion of the
information you need and how you structure each of the objects
that make up an LDW analysis.
Editing Options for Structuring Your Analysis
The options in the Edit menu provide the tools you will need to
structure your analysis. These options let you add, delete, or
modify the various objects that make up an LDW analysis. These
options are briefly discussed here and are discussed in more
detail in the sections for the different views below.
