Abstract Traditional reliability analysis generally uses probability approach to quantify the uncertainty, while it needs a great amount of information construct precise distributions uncertain parameters. In this paper, new technique is developed based on hybrid model, which can deal with problems limited information. All parameters are treated as random variables, some their distribution not given values but variation intervals. Due existence interval parameters, limit-state strip enclosed...
Abstract Epistemic uncertainty is widespread in reliability analysis of practical engineering products. Evidence theory regarded as a powerful model for quantifying and analyzing epistemic uncertainty. However, the heavy computational burden has severely hindered its application problems, which essentially caused by repeated extreme limit-state function (LSF). In order to address issue, this paper proposes novel method solve evidence-theory-based (ETRA). It transforms conventional ETRA...
In this paper, an efficient optimization method named NIO-SLP is suggested for uncertain structures by using the non-probabilistic interval model to quantify uncertainty. A general nonlinear (NIO) problem investigated, in which both of objective function and constraints are uncertain. sequence approximate sub-problems created based on first-order Taylor expansion each one degenerates into a simple linear (LIO) problem. An iterative mechanism proposed update design space whereby make converge...
