Question
Chapter 4.S, Problem 22P
Summary Introduction
To determine: The most cost-effective option.
Introduction:
Mean time between failures (MTBF):
The mean time between failures is a term which denotes the time that is elapsed between the first failure of a product and the second failure of a product. It is calculated during the normal system operation.
Mean time to repair (MTTR):
The mean time to repair is the time incurred for a device to fail and also the time elapsed to repair the device. The repair is carried out after the failure of the device.

In the context of system reliability, explain the difference between Mean Time Between Failures (MTBF) and Mean Time To Recovery (MTTR). How do these metrics impact system design?
The Management Department recently purchased a smallcopier for faculty use. Although the workload of the officestaff has improved somewhat, the secretaries are still making too many trips to the Dean’s office when the departmental copier is out of service. Sylvia, the departmentalsecretary, has been keeping track of failure rates and service times. With a mean time between failures of 100 hoursand a mean time to repair of 24 hours, how much of thetime is the new copier available for faculty use?
The diagram below identifies the elements of service as provided by a soft drink vending machine. Each element has an estimate of its own reliability, independent of the others. What is the reliability of the "system"?
