As a reliability engineer answer the following questions as brief and concise as possible: Although each acceptable answer is worth 5 marks, students may differ on putting emphasis some questions more than others while answering questions and therefore a wide range of different answers to the questions are acceptable. 1. Give a definition of reliability that you think is more precise than other available definition and explains why that is so? 2. Why engineering assets/products fail? And how is that related to system engineering reliability? 3. Why is failure rate important for system engineering reliability? Can you elaborate the impact of failure rates on system engineering reliability? 4. How can you measure/quantify reliability? Is reliability a probability? Can it be predicted and if yes what are the possible basis for its prediction? 5. Why MTBF was popularly applied since World War II? Should we continue to use it? Explain why? 6. Is reliability lower if failure rate is increased? One maintenance engineer argues that after periodical maintenance service, the system reliability is improved because of maintenance actions applied and removal of degraded or possibly faulty parts from the system. 7. Explain the relationship between reliability and the following concepts: availability and maintainability, quality, risk, minimum life cycle cost and optimum life of assets/products? 8. Can you illustrate why system reliability engineering is important for engineering asset management
