Application of Situational Awareness in Reactor-based Infrastructure
Key infrastructure is interdependent and prone to cascading failures.To effectively respond to nationwide events,it is necessary to create a common operational picture to maintain situational awareness.This paper presents a key infrastructure model and analysis method which is suitable for nationwide situational awareness applications.The model uses directed graphs combined with finite state transducers to represent the dependencies and operational states of key infrastructure systems.An analysis method utilizing graph centrality measures is developed to quantify the system-specific and infrastructure-wide impacts of disruptions.Additionally,an entropy-based analysis method is created to estimate the operational states of infrastructure systems in cases of data unavailability.The proposed methods are applied to a practical case study and evaluated using a dataset of system failures observed during a storm period.The results demonstrate that the proposed modeling and analysis methods are suitable for real-time situational awareness applications.
