Density modification based reliability sensitivity analysis
Paul Lemaître, Ekatarina Sergienko, Aurélie Arnaud +3
Sensitivity analysis of a numerical model, for instance simulating physical phenomena, is useful to quantify the influence of the inputs on the model responses. This paper proposes…
Well Placement Optimization under Uncertainty with CMA-ES Using the Neighborhood
Zyed Bouzarkouna, Didier Yu Ding, Anne Auger
In the well placement problem, as well as in other field development optimization problems, geological uncertainty is a key source of risk affecting the viability of field developm…
Chemical differentiation of planets: a core issue
Herve Toulhoat, Viacheslav Zgonnik
By plotting empirical chemical element abundances on Earth relative to the Sun and normalized to silicon versus their first ionization potentials, we confirm the existence of a cor…
Efficient Estimation of Sensitivity Indices
Sébastien Da Veiga, Fabrice Gamboa
In this paper we address the problem of efficient estimation of Sobol sensitivy indices. First, we focus on general functional integrals of conditional moments of the form $\E(ψ(\E…
