Monte-Carlo Finite-Volume Methods inUncertainty Quantification for Hyperbolic Conservation Laws
by S. Mishra and Ch. Schwab
(Report number 2017-38)
Abstract
We consider hyperbolic systems of conservation laws and
review developments in the general area of computational
uncertainty quantification (UQ) for these equations.
We focus on non-intrusive sampling methods of the Monte-Carlo (MC)
and Multi-level Monte-Carlo (MLMC) type.
The modeling of uncertainty, within the framework
of random fields and random entropy solutions, is discussed.
We also describe (ML)MC finite volume methods and
present the underlying error bounds and complexity estimates.
Based on these bounds, and numerical experiments,
we illustrate the gain in efficiency resulting from the use of
MLMC methods in this context.
Recent progress in the mathematical UQ frameworks of
measure-valued and statistical solutions is briefly presented, with
comprehensive literature survey.
