| 요약≠ | Multi-response fault tree analysis (MR-FTA) extends classical fault tree analysis to systems where multiple distinct top-level failure events or outcome metrics must be evaluated simultaneously. Rather than constructing a single tree for one top event, the analyst builds and quantifies parallel trees — one per response — then aggregates results to rank critical failure paths across all responses at once, enabling holistic system risk prioritization. | 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. |
