Q & A

What is reliability engineering?

Reliability engineering is defined as the probability that an item or system will perform its required functions under stated conditions for a specified time interval.

What are the key terms in the definition of reliability?

The three key terms in the definition of reliability are probability, required function, and a specific time interval.

How does reliability relate to statistical principles?

Reliability is inherently probabilistic and non-deterministic, relying on statistical data to determine how well a component or system can function over time.

What factors influence the reliability of a component?

Factors such as environmental conditions, temperature, and stress can significantly affect the reliability of a component.

What are the two types of variables in statistics mentioned?

The two types of variables are continuous random variables, which can take any value within a range, and discrete random variables, which take specific values.

What is the Probability Density Function (PDF)?

The Probability Density Function (PDF) describes the likelihood of a continuous random variable falling within a particular range of values.

What does the Cumulative Distribution Function (CDF) represent?

The Cumulative Distribution Function (CDF) represents the cumulative probability of a random variable taking a value less than or equal to a specified value.

How is reliability function related to failure probability?

The reliability function can be calculated as one minus the cumulative distribution function of failure probability, indicating the likelihood that a component will function successfully over a time period.

What is MTBF and how does it relate to reliability?

Mean Time Between Failures (MTBF) is a measure used to indicate the reliability of a system, calculated as the average time between failures of a system during operation.

What role does live testing play in determining reliability?

Live testing provides more accurate data for reliability analysis compared to laboratory testing, as it reflects real-world usage conditions and stresses.
