Cost Benefit Assessment of Candidate Decision Aids for Naval Air ASW.
Abstract
General methodologies are developed for assessing potential benefits and costs of candidate (early design stage) decision aids. Two types of decision aiding benefits are considered -- increases in mission achievement, and decreases in operator workload. The methodology assess both benefits across a range of related scenarios. Cost assessment considers total costs of developing, implementing, and maintaining an aid as well as savings, e.g., removal of equipment superseded by the aid, simplification of training procedures. Net costs are computed by subtracting savings from total costs. The benefit assessment methodology is applied to two candidate decision aids for the Naval Air ASW Tactical Coordinator (TACCO). One, the Sonobuoy Pattern Planning Decision Aid, helps the TACCO utilize in-situ environmental conditions and intelligence updates during selection of sonobuoy search pattern. The other, the Attack Planning Decision Aid, helps the TACCO obtain attack criteria and place an optimal attack. Both aids produce substantial increases in mission achievement. The Sonobuoy Pattern Planning aid yields a moderate decrease in operator workload, while the Attack Planning aid yields a more sizable decrease in operator workload. Further development of both aids is deemed justifiable, and a detailed man-machine interface for the Sonobuoy Pattern Planning Aid is presented. (Author)
