Abstract: According to demands of uncertainty quantification for reliability certification, in hierarchy of complex engineering system and development from calibration, verification & validation to prediction ability of modeling & simulation (M&S), the principle and method of uncertainty quantification of M & S are investigated. An example on detonation process is shown in which the ideas are demonstrated.

Key words: numerical simulation, uncertainty quantification, verification&validation, reliability certification
