Exam Problem 3 Turlock Irrigation District's main irrigation substation is controlled by a super computer with four individual modules. In order for the substation to function at maximum efficiency, the super computer must work properly and the four modules must function. The four modules have an individual reliability of0.97, 0.92, 0.99 and 0.95. Extend answers four decimal places A. (1) What is the reliability of the super computer? (2) What is the super computer failure rate? B. A back up computer will be installed in the event of the super computer's failure. It will function identically to the super computer. (1) Assuming the backup computer automatically functions if the super computer fails, what is the resulting reliability? (2) Is the reliability better or not? C. If the back up computer must be activated by a switch in the event the super computer fails and the switch has a 0.965 reliability. What is the overall reliability of the system? D. Identify the Rulels) for Parts A-C
