Compare the reliability of A with B. Solve the question and write which one is a better design. UPS Gen A Gen UPS UPS Gen Two designs are proposed to provide uninterrupted electrical power to the ATC system which must be online 24 hours/day, 365 days/year. One failure every five years is the most that can be tolerated. • Design A has two UPS (Uninterruptible Power Supply) systems (one redundant) working with a generator. • Design B has two generators (one redundant) working with a UPS system. Manufacturer's MTBF data is: UPS 150,000 hr; Gen 273,750 hr. Which is the more reliable design, A or B?
