Unformatted text preview: process with increments of one second and a variance of 0.1V 2 . If the voltage of the power supply varies from nominal by more than 3V, it will cause the entire system to fail. What is the expected value of time to failure of the system? If the variance is cut to 0.03V per increment, what is the expected value of time to failure of the system? You may demonstrate your anwers using closed form mathematics or simulations. 4) The unreliability F(t) i of each element of the system below was reduced by a factor of two (through robust design of course). What was the approximate effect on system reliability R(t)? 2 1 3 4 This system will fail if subsystem 1 fails or if subsystems 2,3, and 4 fail. 2 of 2...
