An air supply system for a power plant is being designed. There are two options unde consideration. The first option has two subsystems connected in parallel; the failure rate of each subsystem is equal with A1 = 0.01 per hour. Both subsystems must work for the air supply to fully function. A B The second option connects the subsystems with A as the main supply, providing 100% of the ai requirement, and B acting as a 100% cold standby. In this case, however, each subsystem has a higher failure rate of A2 = 0.02 per hour. The reliability of the "cold standby" switch is 0.95. A Switch B For a daily service time of 8 hours, which alternative has a higher reliability? Why?
