| Tiivistelmä≠ | Optimization-assisted reliability analysis couples probabilistic reliability assessment with mathematical optimization to simultaneously identify failure probabilities and find design configurations that satisfy reliability targets at minimum cost or weight. Widely applied in structural, mechanical, and aerospace engineering, it integrates methods such as FORM, SORM, or Monte Carlo simulation within an optimization loop so that design decisions are driven by quantified risk rather than deterministic safety factors alone. | Statistical reliability analysis models the time-to-failure of components, systems, or products using parametric lifetime distributions fitted to observed or censored failure data. Formalized comprehensively by William Q. Meeker and Luis A. Escobar in their 1998 Wiley monograph, the framework integrates maximum likelihood estimation, censoring mechanisms, and distributional diagnostics to produce probability-of-failure curves, hazard rates, and quantile estimates that support design, warranty, and maintenance decisions. |
