Comparison of some reliability assessment methods.

Methods & Techniques	Preferred Step(s)	Benefits	Limitations	Ref
Failure Mode Analyses (FMMA, FMEA, and FMECA)	Design	Comprehensive Implementation	Scoring requires consensus	[28]
Tree Analyses (FTA, ETA, and BBN)	Design, Implementation	Events interdependencies are represented as a graph. Helpful for decision making	Heavy for high level granular system	[29,30,31,32]
RBD	Design	Design Optimization and uncertainties consideration	demanding in terms of computational resources	[19]
Hazard Analyses	Design, Operation	Hazards structuration Specifies operational risk factors	Heavy documentation Well-defined targeted system	[33]
Markov Chain	Operation, Maintenance	Used to model dynamic problems and maintenance processes	demanding in terms of computational resources	[34]
Monte Carlo Simulation	Operation, Maintenance	Straightforward Implementation Helpful for decision making	Computational resources consuming	[35]
