Expert Solution & Answer
Chapter 11, Problem 11.3E
Explanation of Solution
Reliability Metrics:
To specify the required reliability for a train protection system, the most appropriate reliability metric is Probability Of Failure On Demand (POFOD).
- It is defined as the probability to which the system will respond correctly when a request is made for service at a given point of time.
- This metric is used for protection systems where demands for service are intermittent and relatively infrequent over the system lifetime...

A factory manager has hired your company to develop and install a surveillance system in a factory. The system includes cameras small enough not to be noticed. Supervisors and security personnel can view images and record audio in real-time on monitors in a control room. The system will also store video. The factory manager has not disclosed the placement locations for the new system. The factory manager says the purposes are to watch for safety problems and for theft of materials by workers. What issues, specifications, and policies will you discuss with the factory manager or your company? What would you do?
