Abstract

Robustness is the ability of systems to survive unforeseen or unusual circumstances, allowing them to withstand local damage and redistribute stresses to reduce disruptions from component failures. It may be measured by calculating the probability of system failure when specific components fail, compared to the overall system reliability. However, treating robustness and reliability as opposites can be misleading. To clarify, recent methods suggest plotting reliability and robustness separately on a Reliability-vs-Redundancy plot, allowing for a simultaneous quantification of both aspects. This paper applies Reliability-vs-Redundancy plots to several exemplificatory case studies, to (1) illustrate patterns for simple structures, (2)... (More)

Robustness is the ability of systems to survive unforeseen or unusual circumstances, allowing them to withstand local damage and redistribute stresses to reduce disruptions from component failures. It may be measured by calculating the probability of system failure when specific components fail, compared to the overall system reliability. However, treating robustness and reliability as opposites can be misleading. To clarify, recent methods suggest plotting reliability and robustness separately on a Reliability-vs-Redundancy plot, allowing for a simultaneous quantification of both aspects. This paper applies Reliability-vs-Redundancy plots to several exemplificatory case studies, to (1) illustrate patterns for simple structures, (2) show effects of various initiating events (like vehicle impacts) associated with different probabilities of occurrence, and (3) incorporate risk aspects by accounting for costs/consequences of failure, which may include disruptions to the wider network.
