Cost breakdown structure (CBS)

The hierarchical tree structure of the system cost elements to analyze.

Alternatives

Additional system designs to analyze to determine which design is the most cost-effective. Alternatives are specified in the Alternatives pane in the Project’s LCC Variables file. For more information, see LCC Variables Files

Time Intervals

The time intervals over which costs are determined. Time intervals are specified in the Time Intervals pane in the LCC Variables file.

Cost Equation Variables

The equations for calculating the costs associated with a CBS element.
