Question: A series system has four independent identical components The reliability
A series system has four independent identical components. The reliability for each component is exponentially distributed. If the reliability of the system at 8,000 hours must be at least 0.999, what MTTF must be specified for each component in the system?
Answer to relevant QuestionsWhy is it difficult to define quality? Is there a difference between quality for a manufactured product and quality for a service? Give some specific examples. Consider the parallel system shown in the accompanying figure. The reliability of each component is provided in the figure. Assuming the components operate independently, calculate the system reliability. A component in an automobile door latch has an exponential time to failure distribution with cycles. What are the mean and variance of the number of cycles to failure? What is the reliability at 8,000 cycles? Suppose that units are placed on test and that two of them fail at 200 and 400 hours, respectively. The test is terminated at 1,000 hours without replacing any of the failed units. Determine the failure rate.
