Review of statistical model calibration and validation-from the perspective of uncertainty structures

Abstract

Computer-aided engineering (CAE) is now an essential instrument that aids in engineering decision-making. Statistical model calibration and validation has recently drawn great attention in the engineering community for its applications in practical CAE models. The objective of this paper is to review the state-of-the-art and trends in statistical model calibration and validation, based on the available extensive literature, from the perspective of uncertainty structures. After a brief discussion about uncertainties, this paper examines three problem categories-the forward problem, the inverse problem, and the validation problem-in the context of techniques and applications for statistical model calibration and validation.
