Statistical, sensitivity and reliability analysis using software FReET

Popis výsledku v původním jazyce

The objective of the paper is to present methods for efficient statistical, sensitivity and reliability assessment. The attention is given to the techniques which are developed for an analysis of computationally intensive problems which is typical for anonlinear FEM analysis. The paper shows the possibility of "randomization" of computationally intensive problems in the sense of the Monte Carlo type simulation. Latin hypercube sampling is used, in order to keep the number of required simulations at anacceptable level. The technique is used for both random variables' and random fields' levels. Sensitivity analysis is based on nonparametric rank-order correlation coefficients. Statistical correlation is imposed by the stochastic optimization technique- the simulated annealing. The multipurpose software FReET is briefly described. The most interesting applications of FReET software are referenced in the paper.
