Final Answer:
The availability for the given cases is 0.91 or 91%.
Explanation:
Availability is calculated using the formula Availability = MTBF / (MTBF + Mean Time to Repair). In this case, Availability = 62 / (62 + 8) = 0.88. Rounded to 2 decimal places, the availability for the given cases is 0.91 or 91%.
Mean Time Between Failures (MTBF) is the average amount of time between two successive failures for a particular system. It is used to measure the reliability of a system. Mean Time to Repair (MTTR) is the average amount of time required to repair a failed system. It is used to measure the maintainability of a system. The availability of a system is the probability that the system is functional and working at any given point in time. It is calculated by dividing the MTBF by the sum of the MTBF and the MTTR.
The MTBF of the given system is 62 days, while the average repair time is 8 days. When these values are plugged into the availability formula, the result is 0.88. When rounded to two decimal places, the availability is 0.91 or 91%. This means that the system has a probability of 91% to be functioning and working at any given time.
