Fault Tree Analysis

Fault Tree Analy­sis is a top-down, deduc­tive approach to under­stand­ing how a series of low­er-lev­el events can result in an unde­sired event, acci­dent, or equip­ment fail­ure. This dia­gram uses a set of sym­bols to rep­re­sent for­mal log­ic and to assign prob­a­bil­i­ties. Per­form­ing Fault Tree Analy­sis helps us to under­stand how spe­cif­ic sys­tems can fail, assign risk rates, and iden­ti­fy the best ways to reduce these risks.
