Problem 2-Components reliability Following the implementation of the new design, the number of accidents has decreased; however, the rate of incidents remains unacceptably high. To address this, you request your team analyze the engines to determine whether their reliability can be improved. Using the structural details of the engines and historical accident data, the team has developed the following fault tree Your task is to identify which events in the fault tree should be prioritized for improvement to enhance engine reliability most effectively. To do this, compute the following metrics for each basic event in the fault tree: a) Birnbaum (1p) b) Critical Importance (1p) c) Fussell-Vesely (1p) d) Risk Reduction Worth (1p) e) Risk Achievement Worth (1p) Based on your calculations, determine which component should be improved first and explain your reasoning. (1p)
