Measures in LDW
You define measures in LDW with the measure properties dialog
box. Each measure consists of
! A name, limited to 255 characters.
! An ID Number, limited to 255 characters.
! Units, limited to 255 characters.
! A Goal Above, defining the goal the measure is a
member of.
! A least preferred level, in the measure's units.
! A most preferred level in the same units, and
! An upper cutoff level, above which is unacceptable, also
in the same units.
! A lower cutoff level, below which is unacceptable, also
in the same units.
! Labels, optional text strings that make up a set of
discrete possible choices for the measure levels.
! Comments, an optional text description of the measure.
You can read more about how to define measures on page 6-17.
Quantifying Measure Levels
To let LDW rank the alternatives, you must quantify how well
each meets your goals and objectives. You do this by defining the
level on each measure for each alternative. You can define
measure levels in four ways in LDW -- with point estimates,
labels, probabilities, and measure categories. You can also
evaluate alternatives without defining measure levels by using
the "Analytic Hierarchy Process" or "Direct Entry" method for
computing the common units for the measure.
Point estimates are single numbers that are an alternative's level
on a measure.
If the measure levels fall into several natural categories, you can
describe the categories with brief text descriptions called labels.
You should use probabilistic levels when you don't know the
level of an alternative for a measure with certainty but can
describe it with a probability distribution.
You can use measure categories to define a measure's levels as the
weighted sum of several sub-measures called categories.
