ABSTRACT
This paper extends an earlier published methodology for measuring
the technical performance risk of a system to that of a system-of-systems
(SoS). The earlier work established an approach for combining an individual
system's Technical Performance Measures (TPMs) into an overall
measure of performance risk, defined as the Technical Risk Index (TRI).
This paper extends this approach so a similar index can be developed
for a system composed of many interdependent or connected systems that
come together as a whole to provide an SoS capability.
