This paper compares Evidence Theory (ET) and Bayesian Theory (BT) for uncertainty modeling and decision under uncertainty, when the evidence about uncertainty is imprecise. The basic concepts of ET and BT are introduced and the ways these theories model uncertainties, propagate them through systems and assess the safety of these systems are presented. ET(More)
Methods for designing targeted tests for reliability validation of structures obtained from reliability-based design are presented. These methods optimize the test parameters to minimize the variance in the estimated reliability (or equivalently the failure probability) estimated from the tests. The tests are designed using information from analytical(More)
