Another illustration emanates from the Strength industry. A major ability technology corporation knowledgeable frequent turbine failures, resulting in pricey unplanned downtime.
Fault tree Assessment is often a deductive, major-down solution that visually maps out the reasonable relationships between a failure occasion and its probable results in.
