Abstract: The present invention represents a unique methodology for evaluating subsystem technology in a system-of-subsystems environment. According to typical inventive practice, the technology to be evaluated and the requirements for effecting the technology are defined, the requirements relating to both a subsystem encompassing the technology and a system overarching the subsystem. The technology and the requirements are modeled, the modeling including establishing plural submodels of the subsystem wherein the submodels are considered as characterized by plural linkages between them and as constituting a model of the overarching system. Sensitivity analysis and trade space exploration are performed, the performance including determination of plural design variables of the submodels, plural relationships between the design variables, and respective sensitivities of response variables to the design variables.
