Foreword
NASA has been a leader in most technologies it has employed in its programs over the years. One of the important NASA objectives is now to add Probabilistic Risk Assessment (PRA) to its repertoire of expertise in proven methods to reduce technological and programmatic risk. Fault Tree Analysis (FTA) is one of the most important logic and probabilistic techniques used in PRA and system reliability assessment today. Methods to perform risk and reliability assessment in the
