1. What is reliability centred maintenance? What are the important steps involved in implementing it in any plant?
2. What is the importance of maintenance budgeting? Give the advantage of Zero Based Budget.
3. A remote control unit has 25 components in series. Each component has a reliability of 0.999. What is the reliability of the remote control unit? If it is desired to have a reliability of 0.996 for 3000 hours of operation, what should be the failure rate of each component? Assume that the time to failure for each component is exponentially distributed.
4. Define hazard rate the discuss the three periods or regions of the life cycle of a unit or device as illustrated by the ‘bath-tub’ curve.
5. How can be questionnaire for ‘Maintenance Audit’ prepared? What is the main difference of audition result areas compared to auditing management processes?
6. Write short notes on the following:
a) Maintenance windows
b) Cost Absorption and Cost Apportionment
c) Design and Maintainability
d) Maintenance Audit
