Question:
a) Calculate the Mean Time Between Failures for the following device in days. (365 days in one year)
Meant Time To Failure = 3 years
Mean Time To Repair = 9 days
b) What is the availability of this device in percentage to two decimal places?
c) As Mean Time To Repair approaches 0, availability approaches?
d) As Mean Time To Failure increases, availability approaches?
e) If your company provided a lifetime warranty for the system through an extended warranty service, how many warranty replacements would need to be planned for each each year using the average failure rate, AFR? (use 365 days per year)
