Modeling and Analysis of Uncertainties in Survivability and Vulnerability Assessment.
Abstract
Survivability and vulnerability (S/V) assessment of protective structures involves many uncertainties. Most of the uncertainties arise because of complexity in the weapons effects phenomena and limited data base. Evaluation and analysis of S/V are further complicated by inherent variability (e.g., material behavior, threat scenario, explosive effects) and imprecision (e.g., definition of damage, failure) in every component of the assessment chain. The importance of uncertainties has always been recognized in S/V assessment. However, until very recently, the treatment of uncertainties is limited to statistical techniques. Uncertainties are modeled when it is uncertain. This approach is used to treat uncertainty in the analysis models as well. Keywords: Buried structures; Stochastic equations; Blast; Shock.
