Complexity and Cost Effectiveness Measures for Systems Design

Abstract

This paper proposes two measures intended to aid high level decision makers in
\ncomparing alternatives during pre-competitive studies or during the
\narchitectural design process of composite systems. The first measure is a
\ncomplexity estimate and is based on Boltzmann’s entropy concept. It measures the
\ndistribution of functional couplings in the system’s decomposition. The second
\nmeasure is intended to estimate the costs and benefits of a functional coupling
\nrelated to system’s perfo
