New way of designing systems against correlated disruptions uses negative probability

Until now, systems engineers have struggled with the problem of planning for disaster impacts that are linked by correlation — like those of earthquakes and tsunamis — because of the cumbersome calculations necessary to precisely quantify the probabilities of all possible combinations of disruption occurrences. Now Yanfeng Ouyang and fellow Illinois Engineering researchers have developed a new method for designing and optimizing systems subject to correlated disruptions.
