In this paper, we present a Hierarchical Differential Evolution (HDE) algorithm for minimal cut set (mcs) identification of coherent and non-coherent Fault Trees (FTs). In realistic application of large-size systems, problems may be encountered in handling a large number of gates and events. In...

Dynamic reliability aims at estimating failure risks associated with very rare scenarios, while accounting for the system dynamic evolution. In a Monte Carlo game devised for this purpose, the most time consuming operation consists in performing these dynamic calculations, which are repeated in...

The methodologies employed in the probabilistic safety assessment (PSA) of hazardous engineering systems have reached a high level of maturity. However, a few issues are still worth of further investigation in order to increase the confidence in the results obtained. In this view, in the past...
