available; that is, a crash program substituting resources for time is highly 

 unlikely. As a consequence, the most rational basis for decision-making 

 will include a measure of a candidate's conventionality. 



Capability Matrix. Due to the foregoing assumptions and 

 simplifications, the only system state of concern is the operative one, so 

 the capability matrix reduces to a row vector of k elements. Therefore 



E = e|^ = d(C|^); k = I, . . ., m 



The resulting effectiveness vector will have m terms 

 E = d(cT C2 . ■ ■ c^) 



Each figure of merit, e|^, will have an associated weight W|^, and the 

 dependability will have a weight w^j. The overall effectiveness, E, is defined 

 as 



m 



n 



I = 1 



E = d-d I I ,. Wi 



The product of the figures of merit raised to their respective weighting 

 factor is used to satisfy the requirements of dimensional analysis. A different 

 measure of the overall effectiveness of the systems could be computed using 

 the equation

 i = 1
