   Instantaneous Failure Rate or Hazard Rate • Hazard measures the conditional probability of a failure given the system is currently working. • The failure density (pdf) measures the overall speed of failures • The Hazard/Instantaneous Failure Rate measures the dynamic (instantaneous) speed of failures.

   Failure-Rate Curve is a graphical representation that shows how the probability of failure of a system or component changes over its operational lifetime. It plots the failure rate against time, helping to visualize and analyze reliability and performance characteristics.

   Failure Rate or r(t)- The failure rate of a component or system is expressed as the probability per unit time that the component or system experiences a failure at time t. In such cases, the component or system was using at time zero and has run to time t.

   What is failure rate?

   • Failure rate is the frequency with which an engineered system or component fails, expressed for example in failures per hour. It is often denoted by the Greek letter (lambda) and is important in reliability theory.

   What is annualized failure rate (AFR)?

   • Annualized failure rate (AFR) is the relation between the mean time between failure (MTBF) and the assumed hours that a device is run per year, expressed in percent. Suppose it is desired to estimate the failure rate of a certain component. A test can be performed to estimate its failure rate.

   What is failure per unit time?

   • failure per unit time occurs in the interval given that no failure has occurred prior to the beginning of the interval. It could be constant, decreasing, increasing... Hazard Rate: It is the limit of the failure rate as the length of the interval approaches zero.

   What is failure rate curve?

   • Failure-Rate Curve: The manufacturer conducts tests and generates a curve showing the probability of failure of the components over their expected lifespan. This helps in predicting failure rates and planning for reliability improvements. Scenario: A factory uses machinery critical to production processes.

   What is the failures in Time (FIT) rate of a device?

   • The Failures In Time (FIT) rate of a device is the number of failures that can be expected in one billion (109) hours of operation. This term is used particularly by the semiconductor industry.

   What is failure distribution function?

   • By calculating the failure rate for smaller and smaller intervals of time, the interval becomes infinitely small. This results in the hazard function, which is the instantaneous failure rate at any point in time: Where, T is the failure time. The failure distribution function is the integral of the failure density function, f(x),
