Dynamic aspects and behaviors of complex systems in performance and reliability assessment

Reliability and performance evaluation are important, often mandatory, steps in designing and analyzing (critical) systems. In such cases, accurate models are required to adequately take into account interference or dependent behaviors affecting the system, its parts and the external environment, especially if the system experiences high complexity. The techniques and tools to adopt in the evaluation have to adequately fit the problem considered. The main goal of this paper is to identify the dynamic-dependent aspects that can affect the reliability and performance of a system. Starting from the concept of dependence at the basis of system decomposition, an analytic framework and some of the most important dynamic-dependent aspects and behaviors are characterized in terms of both dynamic reliability and performance.
