1. An apparatus comprising: an analytic network process (ANP) storage memory that stores an ANP weighted supermatrix representing an ANP model; and a processor in communication with the ANP storage memory, the processor being configured to facilitate measuring how alternatives synthesize with respect to a fixed node in the stored ANP weighted supermatrix to determine a perspective metric vector for the fixed node; and maintaining a same proportionality in the stored ANP weighted supermatrix, while inducing a family of row perturbation changes within the ANP supermatrix by predetermined amounts of an ANP-row-family-parameter, for the measuring of the perspective metric vector for the fixed node.
