|Abstract:||Development and acquisition efforts of cyberphysical systems can often encounter cost or schedule overruns due to the complexity of the system. It has been shown that certain amount of system complexity is related to the system functionalities (effective complexity), whereas excessive complexity is related to unnecessary intricacies in the design (apparent complexity). While the former is necessary, the latter can be removed through precise local redesign. One of the major challenges of systems engineering today is the development of tools, quantitative measures, and models for the identification of apparent complexity within the system. This research has the goal of evaluating and measuring the structural complexity of the engineered system, and does it through the analysis of its graph representation. The concepts of graph energy and other spectral invariant quantities allow for the definition of an innovative complexity metric. This metric can be applied knowing the design of the system, to understand which areas are more in need of redesign so that the apparent complexity can be reduced.|
