Failure Emergence Probability (Barlow-Proschan)
DT
Not every part of a building is equally likely to fail next, and not every failure matters equally. Using established reliability mathematics, we rank where deterioration is most likely to emerge and do the most harm — so attention and budget go to the surfaces that genuinely need them first, rather than being spread thin.
Failure Emergence Probability models, drawing on Barlow-Proschan reliability theory (notably the Barlow-Proschan importance measure for ranking which components most drive system failure), quantify the likelihood and location of the next failure across a building or portfolio. In ATH they convert the deterministic Time-to-Failure outputs into a probabilistic ranking of where intervention yields the greatest reduction in risk, prioritising the surfaces and assets whose degradation most threatens the whole system.
