Abstract | As modern systems continue to increase in size and complexity, they pose significant safety and risk management challenges. System engineers and much of the government research efforts are focused on understanding the attributes and characteristics that emerge from the interactions of components and subsystems. As a result, the objective of this research is to develop techniques and supporting tools for the verification of the resilience of complex engineered systems during the early design stages. Specifically, this work focuses on automating the verification of safety requirements to ensure designs are safe, automating the analysis of design topology to increase design robustness against internal failures or external attacks, and allocating appropriate level of redundancy into the design to ensure designs are resilient. In distributed complex systems, a single initiating fault can propagate throughout engineering systems uncontrollably, resulting in severely degraded performance or complete failure. This research is motivated by the fact that there is no formal means to verify the safety and resilience properties, and no provision to incorporate related analysis into the design process. |
