with the highest overall utility. The edit box labeled "Utility Lines to Show" determines how many "iso-utility" lines LDW will draw in the figure. The lines will be color coded, with red lines indicating lower utilities and green lines indicating higher utilities. You can select up to 250 lines. Selecting a large number of lines will result in the area of the graph being almost completely covered with varying shades of red and green. If you select only one line, you can enter the utility to show with the single line in the edit box labeled "Utility to Show". LDW will display 10 points along the line and will label them with their levels on the selected measures (see Figure 8-9). When you click "OK", LDW will display a graph like the one in Figure 8-8. Figure 8-8. Example of Review::Graph Pairs of Measures option. The graph is like the tradeoff graph from the Review::Single Tradeoffs option. It shows a rectangle with one measure on the horizontal axis and one on the vertical axis. You can think of any point in this rectangle as a simplified alternative that has the indicated levels on the two measures and a nominal level on all of the other measures. For example, a point in the upper left corner of the rectangle represents a computer alternative with a hard disk size of 120 mb and a hard disk access time of 15 ms (the best hard drive in the rectangle). A point in the lower right corner 8-10 Section 8 -- Using LDW 3: Reviewing Results
epresents a computer alternative with a hard disk size of 60 mb and a hard disk access time of 28 ms. A point in the very center of the rectangle would represent a computer alternative with a hard disk size of 90 mb and a hard disk access time of 21.5 ms. The lines on the graph represent sets of simplified alternatives that you prefer equally. LDW labels each line with the utility that would be assigned to that line if the two measures were the only ones in the analysis and had their own Multi-Measure Utility Function (MUF) based in their relative weights and Single Measure Utility Functions. Crosses that appear on the graph represent the levels of actual alternatives on the two measures. Figure 8-9 shows an example of the option with a single utility line of u = 0.75 displayed. LDW draws 10 points along the line and labels them with their levels on the horizontal axis and vertical axis measures. Figure 8-9. Example of Review::Graph Pairs of Measures option with one utility line.
