Abstract

Fault Tree Analysis (FTA) is a kind of way to consider synthetically, quantificationally the systems' abnormality. The thesis is focused on the Lifeline analysis. Using fault tree analysis, we use the Beijing urban lifeline to emphasize the early warning and risk assessment. The establishment of pipeline corrosion, pipeline defects, third-party damage, voltage regulator leakage, valve leakage are the major resons for gas pipeline default.
