Figure 8-29. Dialog box for Results::Scatter Diagrams option. The two lists in the dialog box determine the members that will be shown on the diagram’s axes. The cost member is shown on the horizontal axis in nominal units such as dollars. The benefit member is shown on the vertical axis in units of utility. The benefit member is often a goal that aggregates the various measures of benefit. The “Benefit/Cost Multiplier” edit lets you enter a constant to multiply the benefit cost ratios by, since cost numbers in dollars are usually much larger than benefit numbers in utility. When you click the "OK," LDW creates a display like the one in Figure 8-30. 8-34 Section 8 -- Using LDW 3: Reviewing Results
Figure 8-30. Example of Results::Scatter Diagram option. The ranges for the two axes go from 0.0 to the sums of the costs and benefits for all the alternatives with positive benefits and non-negative costs. The alternatives are shown along a line that starts from the zero cost/zero benefit point in the lower left and adds alternatives along the line in order of decreasing cost benefit. If you move your mouse over a point, its label will be shown temporarily. The label has the alternative name and the benefit/cost ratio adjusted by the multiplier you entered in the dialog box. LDW also displays the alternative’s cost and benefit levels as well as the cumulative cost and benefit at the bottom of the graph. If you click on a point the label and details will be shown permanently. If you click on a label it and the details will be hidden. Interpreting the efficient frontier. If you are selecting multiple alternatives in your analysis, you can think of the efficient frontier as the order in which you should buy them so that you get the Section 8 -- Using LDW 3: Reviewing Results 8-35
