Calculate using alternatives
|
Indicates whether to calculate using alternatives. When this checkbox is cleared (default), all other properties on this page are unavailable and ignored during LCC calculations. If this checkbox is cleared when variables do vary by alternatives, zero is used as the value for each variable. When this checkbox is selected, other properties are made available on this page. The equation for each item in the CBS tree is run once for every selected alternative. If time intervals are also selected, see Alternative and Time Interval Calculations for more information.
|
All alternatives
|
When selected, cost calculations run for all alternatives in the LCC Variables file.
|
Selected alternatives
|
When selected, the buttons described in Alternative and/or Time Interval Selections become available so that you can add and remove specific alternatives from those in the LCC Variables file. The Available list on the left displays the alternatives that are available for selection. The Selected list on the right displays the alternatives that have already been selected.
