A fuzzy-parameterised stochastic modelling system for predicting multiphase subsurface transport under dual uncertainties

Abstract

A fuzzy-parameterised stochastic modelling system (FPSMS) was proposed in this study to investigate the impacts of uncertainties associated with hydrocarbon contaminant transport in subsurface. FPSMS integrated the multiphase numerical simulator, the fuzzy transformation method, and the Monte Carlo simulation technique into a general modelling framework, and was capable of dealing with coupled probabilistic–possibilistic uncertainties (in …
