g Operations Activity #2: Serial and Parallel Systems un 17#11:59 PM CDT Conceptual Overview: Explore the reliabilities of serial and parallel processes The reliability of a system of components equals the product of the individual reliabilities of each component. In the serial system below, the product of the three reliabilities is 098-o 91-o g9-0 883 Aithough the reliability of each component is above 0 90, the system reliability is only 0.883 because of the multiple chances for a failure Duplicating an unreliable process so that it has two parallel chances to succeed can improve reliability dramatically. The reliability of a parallel process equals one minus the probability that both routes fail. That s, Rnew 1-(1 - Rold) (1-Rold) Click on the unreliable process B below to change it to a parallel process. The new reliability is computed in the middle and is the reliability used in computing the overall reliability of the process. Click on any of the processes to alternate them between serial parallel processes and observe how the overall reliability of the system changes Having a parallel process is obviously more expensive so the company only wants to implement parallel processes when they would improve reliability dramatically, In this case, implementing duplicate systems for which components improves reliability appreciably? 0.98 0.91 0.99 Created bry Gary H, McClelland, Prodessor EmeritusUniversity od Colorado Boulder search
