Reliability Engineering (Industrial Eng.)

Question 2 . A computer controls the guidance system of a ship and it has three major modules. In order for the computer to function properly, all three modules must function. The reliability of two of the modules is 0.94, and the third module has the reliability of 0.98. a. What is the reliability of the computer? b. A backup computer identical to the one being used can be installed to improve overall reliability. Assuming that the new computer can automatically function if the first computer fails. Determine the resulting reliability. c. If the backup computer must be activated by a switch in the event that the first computer fails, and the switch has a reliability of 0.99, what is the overall reliability of the system? (Both the switch and the backup computer must function in order for the backup system to function.)
