The formula to calculate the average availability is:
\[ A = \left( \frac{TA}{TH} \right) \times 100 \]
Where:
Average availability is a measure of the proportion of time that a system, service, or component is operational and accessible when needed. It is typically expressed as a percentage and is used to evaluate the reliability and performance of systems, particularly in fields such as IT, telecommunications, and manufacturing. High availability indicates that the system is rarely down and is almost always available for use, which is crucial for critical applications and services.
Let's assume the following values:
Using the formula:
\[ A = \left( \frac{720}{744} \right) \times 100 = 96.77 \]
The Average Availability is 96.77%.
Let's assume the following values:
Using the formula:
\[ A = \left( \frac{1000}{1050} \right) \times 100 = 95.24 \]
The Average Availability is 95.24%.
