Question: Consider the stand by system shown in the accompanying figure
Consider the stand-by system shown in the accompanying figure. The components have an exponential lifetime distribution, and the decision switch operates perfectly. The MTTF of each component is 500 hours. Assuming that the components operate independently, calculate the system reliability at 1,500 hours.
Answer to relevant QuestionsSuppose you had the opportunity to improve quality in a hospital. Which areas of the hospital would you look to as opportunities for quality improvement? What metrics would you use as measures of quality? Is Deming’s philosophy more or less focused on statistics than Juran? Consider the system shown in the accompanying figure. The reliability of each component is shown in the figure. Assuming that the components operate independently, calculate the system reliability. Continuation of Exercise 9.32. For the data in Exercise 9.32, find a 95% confidence interval on the MTTF and the reliability at 200 hours, assuming that the lifetime has an exponential distribution. In exercise 9.32 An electronic component has an exponential time to failure distribution with hours. What are the mean and variance of the time to failure? What is the reliability at 7,000 hours?
