Safety Assessment of Critical Aircraft Systems Under Multisource Uncertainty Based on Evidence Network

open access: yesInternational Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
As civil aircraft components become more autonomous in China, airworthiness certification is facing the problem of insufficient failure data, leading to challenges in terms of uncertainty. Traditional probabilistic models struggle to effectively integrate multisource uncertainties, limiting their application in data‐scarce scenarios.
