Abstract : This report describes analytical work that was performed to compute measures of effectiveness (MOEs) of advanced marine vehicles (AMVs) in performing search and rescue (SAR) missions. The report also discusses difficulties that were encountered in analyzing the SAR data base. The objective of this study is to search the 1981 SAR data base for information that is pertinent to an analysis of an AMV in performing SAR missions. Correlations are identified between the probability of saving lives and other factors in the SAR data base, especially environmental factors and time delays. These correlations are used to quantify the potential contribution of the AMV to overall SAR performance under a range of environmental conditions. Survival curves generated from the 1981 SAR data base show that in approximately one third of the SAR cases, the probability of survival very definitely degrades with time. Consequently, a high-speed AMV could provide an increase in the probability of saving lives in cases where distance to scene is substantial. The relatively shallow slope of the curve suggests, however, that moderate speed advantages or speed advantages over short distances(especially if get-away time is increased for the AMV) will have little or no effect on SAR mission effectiveness.
