almost equally unacceptable, while as power increases above 122 hp each additional horsepower really makes a difference. Suppose you again use the mid-level splitting technique and find that your mid-preference level for the range from 109 to 130 is 122 hp. We want to modify the lower SUF range to reflect this. Make the modification as follows: 1. Select the 109-130 range by clicking on its line. You can also use the left arrow key to move the selection from the split point to the adjacent sub-range. 2. Set the mid-preference level by typing the number "122" in the "Level" edit box. This results in the SUF shown in Figure 4-6. Figure 4-6. Result of setting mid-preference level of 122 for range from 109 to 130 hp. Similarly, you can set the mid-preference level for the higher range. Assume that the mid-level splitting technique tells you that your mid-preference level is 140 for the range from 130 to 175 hp. You might get this result if you feel that there are decreasing returns for horsepowers over 130. 4-14 Section 4 -- Introductory Tutorial
1. Press the left arrow key to "wrap around" and select the upper 130-175 range. 2. Set the mid-preference level for the range by typing "140" in the "Level" edit box. Don't forget to press Enter to update the graph. You should get the SUF shown in Figure 4-7. This completes the definition of the SUF for Power. Figure 4-7. Final SUF for Power. Assessing the SUF for a Measure With Labels. Since the "Styling" measure uses discrete labels rather than a continuous scale, we need to use a different method to convert its levels to common units. We will use the direct assessment method to directly assign a utility for each label. To do this: Section 4 -- Introductory Tutorial 4-15
