Suppose that a system consists of four subsystems. For the baseline configuration, the system will fail if each subsystem fails. The reliability data of each unit that comprise each subsystem in the baseline configuration are given as: unit 1 (Exponential distribution, A=2000), unit 2 (Weibull distribution, A=2000, B=3.7), unit 3 (Rayleigh distribution, A=1500, B-2) and unit 4 (Exponential distribution, A=1200). The time is in hours. Use Excel to do the following computations. a) For the baseline configuration, calculate the system reliability for 3000 hours of operation. Also calculate the system MTTF. On one plot show the subsystems and the system reliability functions as a function of time. Suppose that a system consists of four subsystems.
