Tóm tắt	Multi-response Event Tree Analysis (MR-ETA) extends classical event tree analysis by simultaneously tracking multiple system performance or safety response variables across all accident sequences. Instead of evaluating a single outcome (e.g., probability of failure), it propagates several concurrent response metrics — such as damage severity, downtime, cost, and environmental impact — through the event tree branches, enabling richer risk characterization and trade-off decisions under a single probabilistic framework.	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.
