Question

Document1 Word ll me what you want to do A device used in a ground radar system has age to failure that is described approximately by a Weibull distribution with characteristic life of 83 hours, shape parameter 1.5, and location parameter zero. Assume a constant failure rate. When it fails it takes on average 3.5 hours to repair 1. a. Calculate the reliability over a 25-hour period, and the steady state availability of the device. b. Calculate the reliability over 25 hours, and the steady state availability of a subsystem that consists of two of these devices in active parallel redundancy c. Identify all assumptions made in these calculations and discuss their validity
