1. Consider a manufacturing process composed of three stages – (R1, R2 and R3). Stage one consists of 2 machines arranged in a doubly redundant sub system. Stage two has 3 machines that work in series, meaning that this stage operates successfully only if all the machines operate. Stage three is made up of 4 machines and only operates successfully if at least 2 machines operate. The three manufacturing stages are connected in series to produce the final product, meaning that they must all work properly to produce a final product.
Between two scheduled maintenances, each machine may fail independently of the others, with the following failure probabilities: R1 0.18 0.22 R2 0.19 0.29 0.28 R3 0.35 0.24 0.19 0.38 Use this information to answer the following questions to 3 decimal places (expressing probability as a number between 0 and 1 and do not specify units or enter text of any kind): 1. The reliability of sub system stage 1 is. 2. The reliability of sub system stage 2 is. 3. The reliability of sub system stage 3 is. 4. At stage 3 the probability of 2 machines breaking down between scheduled maintenances is. 5. The probability of the manufacturing process as a whole failing between scheduled maintenances is.
