Dynamic generation of scenario trees
WebJul 10, 2006 · This paper presents a system software infrastructure that supports execution and analysis of multiple dynamic event-tree simulations on distributed environments for testing of event tree completeness and the assessment and propagation of uncertainty on the plant state in the quantification of event trees. Level 2 probabilistic risk assessments … WebIn this paper, relying on a discrete modeling framework, we present a scenario generation algorithm able to capture this time-varying asymmetric tail dependence, and evaluate resulting optimal investment policies based on 4-stages 1-month planning horizons. The scenario tree aims at approximating a stochastic process combining an ARMA-GARCH ...

WebNov 1, 2010 · The scenario trees serve as an approximation of the true multi-dimensional probability distributions of the problem’s random variables. Improving the accuracy of this approximation requires larger trees. Larger trees, in turn, mean higher computational effort, which may quickly become prohibitive.
