... 1Mission effectiveness and a number of other utility measures are defined in Appendix C, "A Framework for Comprehensive Analysis." 2The methodology considers multiple missions, many interdependent design variables, many operational threats, and mission effectiveness and survivability metrics.

From page 59...
... The committee assessed aircraft survivability as a function of speed and signature for a current widespread SAM threat, the current stressing SAM threat, and a projected advanced responsive threat. As the examples above suggest, the studies examined by the committee varied significantly in design variables, parameters, mission vignettes, specific threats, assumptions, and utility metrics considered.

... The results provide the means for the Air Force to carry out trade-off studies to establish a family of baseline configurations for systems that could achieve IOC in 2018. Additional analyses extending the studies presented to the committee will enable the refinement of those baseline configurations.
