Sensitivity Analysis in Cost-Benefits Analysis

Methods and Models II Track



The Army has been using Cost-Benefits Analysis (C-BA) for all new requirements with cost impact for two years. As with the Analysis of Alternatives (AoA), a sensitivity analysis of the C-BA results is required. The C-BAs frequently use weighted decision matrices to combine the benefits into a single Cost-Benefit Index. This greatly simplifies the sensitivity analysis and facilitates allocation of cost to the individual benefits. The author reviewed the sensitivity analysis in 80 C-BAs. This session will address some of the techniques for presenting sensitivity analysis, the basic math behind the sensitivity analysis and allocating cost to benefits and generalizing the results to more complicated problems.
