Parsimonious Estimation of Probabilities of Undesirable Events in Structural Reliability Frameworks
We consider the exceedance of a threshold reliability value by the unidimensional output of a computer code G with multivariate probabilistic input v. When G is assumed monotonous with respect to v, the Monotonous Reliability Method, proposed by de Rocquigny (2009) in an engineering context, can provide bounds and crude estimates of the probability of occurence pf of such an undesirable event, using a sequential design of experiments. In the talk associated to this article, the formalization and a technical deepening of this idea are considered, as a large basis for future theoretical and applied studies in structural reliability. Two refined statistical estimators of pf are defined and their parsimonious properties are showed, which makes them useful in the frequent industrial context when the code G is time-consuming.
