A model function f(x1,…,xn) defined in the unit hypercube Hn with Lebesque measure dx=dx1…dxn is considered. If the function is square integrable, global sensitivity indices provide adequate estimates for the influence of individual factors xi or groups of such factors. Alternative...

Composite indicators are regularly used for benchmarking countries’ performance, but equally often stir controversies about the unavoidable subjectivity that is connected with their construction. Data Envelopment Analysis helps to overcome some key limitations, viz., the undesirable dependence...

Composite indicators are increasingly used for bench-marking countries' performances. Yet doubts are often raised about the robustness of the resulting countries' rankings and about the significance of the associated policy message. We propose the use of uncertainty analysis and sensitivity...

In computer experiments they are often used to gain accuracy in the estimation of global sensitivity statistics. However, one faces the question of interpreting results...</p>

This report is the first part of a dilogy which aims to be a compendium for regulators without a specific background in risk and safety assessment. It describes the state-ofthe- art of the safety-related equipment, methods, procedures and projects available nowadays for the prevention of risks,...

Uncertainty and sensitivity analysis was conducted on the SHERPA model, predicting air quality improvement linked to emission reduction scenarios. Major responsible of output uncertainty (PM2.5 concentration reductions in g/m3) stems from the uncertainty in the policy options followed by the...

The blowout on the Deepwater Horizon drilling rig on April 20th 2010, whilst drilling the Macondo well in the Gulf of Mexico, significantly raised worldwide awareness of the risks involved in offshore oil and gas operations. In addition to the tragic loss of eleven lives, the blowout released...
