Abstract

"Uncertainty exists in any engineering applications. Uncertainty is usually classified into two types - Aleatory and Epistemic. Aleatory uncertainty describes the inherent variation associated with a physical system or environment while epistemic uncertainty is derived from some level of ignorance or incomplete information about a physical system or environment. Aleatory uncertainty associated with parameters is usually modeled by probability theory and has been widely researched and applied ;by industry, academia and government. The study of epistemic uncertainty is relatively new. The objective of this research is to investigate sensitivity analysis when both types of uncertainties are involved"--Abstract, page iii.
