The formula to calculate the Failure Rate (fr) is:
\[ fr = \frac{TF}{TT} \]
Where:
A failure rate is a measure of the frequency with which an engineered system or component fails, expressed in failures per unit of time. This metric is commonly used in industries such as manufacturing, where it is crucial to track equipment reliability and the consistency of produced goods.
Let's consider an example:
Using the formula to calculate the Failure Rate:
\[ fr = \frac{5}{100} = 0.05 \, \text{failures/hour} \]
This means that the failure rate is 0.05 failures per hour.
