Q A circuit board has 4 components A B C & D having reliability of 0.990,0.995,0.890 and 0.980. what is the reliability of circuit board? Two alternatives suggested to increase system reliability are; a. Redesign, develop and test a new over designed configuration of component C at a cost of Rs 25000 which would result in a component reliability of 0.960 for component C. b. Modify the circuit board with a back up component C which is automatically placed into service if the primary component fails. This use of redundancy would cost Rs 10,000. Compute the system reliability of these two alternatives. Which one to choose?
