Reference Answer
### (a) Fault Tree Analysis (FTA)
**1. Concept and Definition:**
Fault Tree Analysis (FTA) is a top-down, deductive analytical technique used in safety and reliability engineering. It begins with a predefined undesirable outcome, known as the **Top Event** (e.g., a system failure), and systematically traces backward to identify all possible contributing causes, including component failures, human errors, and external events. The analysis results in a graphical logic model—the fault tree—that depicts the causal relationships leading to the top event.
**(Sourced from retrieved context):** FTA's primary purpose is to identify potential causes of system failures before they occur and to evaluate the probability of the top event using Boolean logic. It is widely applied in high-risk industries like nuclear, aerospace, and chemical processing to understand failure modes and mitigate risks.
