Fault Tree Analysis Concepts

This video tutorial from Digital eLearning introduces Fault Tree Analysis (FTA), a top-down approach used to identify the causes of undesired events. The video explains the types of events and logic gates used in FTA, and provides qualitative and quantitative analysis methods. Two case studies are presented: one on a missed bus scenario and another on a pool collapse, demonstrating practical applications of FTA. The tutorial concludes with a call to follow Digital eLearning on social media.

What is the primary approach used in Fault Tree Analysis (FTA)?

• Sideways approach

• Top-down approach

• Bottom-up approach

• Circular approach

Who originally developed Fault Tree Analysis (FTA) in 1962?

• Nikola Tesla

• H J Watson

• Isaac Newton

• Albert Einstein

What is an undeveloped event in FTA?

• An event that can be further developed

• An event that is always ignored

• An event with no scope of further development

• An event that occurs at the top level

Which logic gate in FTA requires all input events to occur for the output event to occur?

• NOR gate

• AND gate

• XOR gate

• OR gate

What type of information does qualitative FTA provide?

• Probability estimation of a top event

• Cost analysis of a project

• Path route causes and weak areas

• Time required for project completion

What is the purpose of quantitative FTA?

• To estimate the probability of a top event

• To create a new event

• To identify the weakest link in a system

• To develop new logic gates

What should be done if corrective actions are required according to quantitative FTA?

• Increase the probability of fault occurrence

• Remove all logic gates

• Ignore the fault path

• Develop measures to eradicate the fault path

In the 'Missed the Bus' example, what are the two events leading to 'I wake up late'?

• I was lazy and I had a faulty alarm

• I walked slowly and I had a pain in my leg

• I slept late and the alarm did not ring

• I had a late breakfast and I met a friend

In the 'Pool Collapse' example, which event is considered a basic event?

• Too much pressure against the walls

• Missing parts

• Faulty construction

• User does not follow instructions

What is the key takeaway about creating an FTA?

• Multiple approaches can be valid as long as the team agrees

• There is only one correct way to create an FTA

• FTAs are only useful in the aerospace industry

• FTAs should always be created by a single person
