सारांश	Hybrid Failure Mode and Effects Analysis (Hybrid FMEA) extends classical FMEA by integrating it with multi-criteria decision methods — such as fuzzy logic, AHP, TOPSIS, or grey theory — to overcome the well-documented limitations of the traditional Risk Priority Number. The hybrid approach enables more nuanced, weighted, and uncertainty-aware prioritization of failure risks in engineering systems, manufacturing processes, and complex sociotechnical environments.	Fault Tree Analysis (FTA) is a top-down, deductive reliability method that begins with an undesired top-level failure event and systematically traces backward through chains of contributing causes using Boolean logic gates (AND, OR). First formalized by Watson at Bell Telephone Laboratories in 1961 and later standardized by Vesely, Goldberg, Roberts, and Haasl in the landmark 1981 NRC Fault Tree Handbook, FTA has become a cornerstone of quantitative risk assessment in nuclear, aerospace, and industrial safety engineering.
