Cost Benefit Analysis (CBA) for Human Effectiveness Research Biacoustic Protection.

摘要

Human Systems IAC was asked to assess the costs and benefits associated with providing improved hearing protection for Air Force flightline personnel. To ensure individuals with a direct stake in this area of study were included, input was obtained from subject matter experts as well as stakeholders such as Air Force fighter pilots and maintenance crew chiefs. A standard eight- step process was used to identify and evaluate the costs and benefits associated with the current bioacoustic protection system in use and two alternative systems. This study evaluates the costs and benefits associated with three hearing protection alternatives. Each alternative was estimated for cost and evaluated for relative benefits. By assigning a numerical value to the benefits, Human Systems IAC was able to develop a cost/benefit ratio (CBR) for each of the three alternatives. The lower the CBR, the more desirable the alternative. Human Systems IAC found that the most effective alternative with respect to the stated goals is alternative number 3, ACCES with ANR (CBR = 9.0). The second most desirable alternative was ACCES (CBR = 10.9). Based on the evaluated cost and benefits the least cost effective solution in providing hearing protection was alternative number 1, the fielded system (CBR = 11.6).
