Figure 8-12. Example of Review::Weights::Percentage Weights display. LDW displays the weights as percentages that sum to 100 percent. It includes all measures in the analysis, no matter which goal they belong to or whether individual goals have their own MUFs. The table does not include any effects from interactions. The first column, labeled "Percentage Weights," contains the weights that result from using the "nominal" ranges of the measures defined using the dialog box for each measure. The second column, labeled "Effective Weight" contains the weights that would result if the range for each measure specified in its properties dialog box corresponded to the range of the alternatives on that measure. If the alternatives vary over a wider range than the properties range for a measure, the effective weight will be higher than the percentage weight (assuming no changes in the other measure's ranges). Conversely, if the alternatives vary over a narrower range than the properties range, the effective weight will be lower than the percentage weight. In the extreme case where the alternatives all have the same level on a measure, the effective weight will be zero, since that measure does not help to distinguish between the alternatives. This may 8-14 Section 8 -- Using LDW 3: Reviewing Results
e true even if the measure has a very high percentage weight. All of the other displays in LDW are based on the percentage weights rather than the effective weights. MUF Formulas The MUF Formulas display lets you view the scaling constants that define the Multi-measure Utility Functions (MUFs) for the current preference set. You can view the MUF Formulas table by selecting the Review::Weights::MUF Formulas option. When you select it, LDW displays a table like the one in Figure 8-13.
